Earthquake today. Interactive map of volcanic activity
Where can I find the forecast for Ecuador?
On your website I only found information on aftershocks (replicas), but they
here they repeat 10-20 per day.
1. The main impact of 7.8 points and 4 times more powerful than Japan occurred not in the mountains, but in the ocean!!!
2. Pendulum vector = north-south, then west-east, and then sharply downward, like in a cyclone.
The feeling was that it wasn’t the ceiling that was moving, it was the floor. Like a vacuum under your feet.
3. Typically, the 1st-4th floors of high-rise buildings were destroyed. The top floor was the least damaged.
4. The volcanoes of Ecuador did not respond. What if they answer? Andes, Cordillera, Iceland, Kuril Islands,
Japan, etc. , the entire Pacific Rim is in turmoil. It won't seem enough.
5. I don’t see an analysis of the situation. Or the actions of scientists can only be seen in movies like "2012"
San Andres Fault...?
IN recent years 20-25 on planet Earth the process of its compression intensified, i.e. reducing its volume. Accordingly, the number of earthquakes and volcanic eruptions throughout the ball increased sharply.
Moreover, a pattern is noted: volcanic activity replaces seismic activity and vice versa. Minor shaking of the earth around erupting volcanoes does not count.

Let's take an area with increased seismic activity - the Kamchatka Peninsula.
Statistics of events by year or by century where?
Hello!
I would like to hear the forecast for Antalya; this month there have already been three significant earthquakes, and there is a clear upward trend.
12/28/2013 there were 6.0 points in the Mediterranean Sea
12/25/2013 was 4.3 points Serik (Antalya)
12/08/2013 there was 5.0 points in the Mediterranean Sea
Smaller ones are 3-4 points almost every day, but they are not felt, but we felt these ones.
I noticed one more pattern. I’m not sure whether we can talk about an increase in gravitational attraction in the regions. I don’t run around the Planet with instruments. But this is what is observed! In areas marked by seismic activity, the number of cases increases noticeably:
1. Emergency situations associated with cars falling from bridges and cliffs.
2. Falling from a height or into holes, cracks, ravines...
2. Cases of suicide associated with jumping into the abyss, from bridges and high-rise buildings.
3. Spontaneous destruction of buildings for no apparent reason.
BUT cases should not be isolated!
There is an increase in seismic activity in the Vrancea zone at the end of November 2013. Above 4.0 I predict 100 percent. Entrance in Romania (using the elastic recoil method), it is likely that the epicenter is within a 150 km radius. By dates: November 27,28.
| Nice surprise about this shorter form. Can you tell us what it is you are talking/writing about?Has any info. about this shorter form was posted before (and i just missed |
Most of the largest earthquakes occur according to one scenario: rigid plate structures consisting of earth's crust and mantles move by colliding with each other. There are 7 largest plates in the world: Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
Over the past two billion years, the movement of plates has accelerated significantly, which, accordingly, has increased the chances of such a catastrophe. On the other hand, based on displacement studies tectonic plates, scientists can, albeit roughly, predict the occurrence of the next major earthquake. Based on publicly available data, we have compiled a list of cities where the likelihood of such an event is already very high.
San FranciscoA powerful earthquake with an epicenter in the Santa Cruz Mountains, about a hundred kilometers from the city of San Francisco, is just around the corner. Or rather, over the next couple of years. However, most residents of the City by the Bay prepared for the disaster by stocking up on medicines, drinking water and food products. In turn, the city authorities are busy urgently carrying out work to strengthen the buildings.
FremantleFremantle is a port city located on the west coast of Australia. According to seismological studies by specialists from the University of Sydney, a strong earthquake of about 6 points on the Richter scale is expected there between the end of 2016 and 2024. However, main danger is that a shock could occur on the ocean floor near the city, causing a tsunami.
TokyoAccording to experts, a major earthquake with an epicenter in the Japanese capital has a 75% probability of occurring at any time over the next 30 years. According to the model created by scientists, about 23 thousand people will become victims of the disaster and over 600 thousand buildings will be destroyed. In addition to increasing the level of seismic resistance of buildings and demolishing old structures, the Tokyo administration will introduce non-combustible building materials. The Kobe earthquake in 1995 showed the Japanese that people more often become victims not of collapsed buildings, but of fires that occur after a disaster.
Los AngelesEarthquakes happen quite often in the City of Angels, but there haven't been any truly major ones for over a century. The gloomier is the forecast presented by seismologists and geologists from the US Geological Society. Based on the analysis of soils and tectonic plates under central part California, scientists have concluded that an earthquake of magnitude 6.7 may occur here before 2037. A shock of such force, under certain circumstances, can turn a city into ruins.
PanamaWithin a few next years A powerful earthquake measuring more than 8.5 on the Richter scale will occur in the area of the Isthmus of Panama. Experts from the University of San Diego came to these conclusions after conducting seismological studies of faults adjacent to the Panama Canal. The effects of an earthquake of truly catastrophic proportions will be felt by the inhabitants of both Americas. And most of all, of course, the capital of the republic, Panama, where about 1.5 million people live, will suffer.
Petropavlovsk-KamchatskyA strong earthquake in the medium term, i.e. in the next 4-5 years, will occur in the Petropavlovsk-Kamchatsky area. Such data were reported in the seismology department of the Schmidt Institute of Earth Physics. In connection with this forecast, work is being carried out in Kamchatka to strengthen buildings, and the Ministry of Emergency Situations is checking the seismic resistance of buildings. In addition, a network of stations was organized to monitor the symptoms of an approaching earthquake: high-frequency vibrations of the earth's crust, water levels in wells, and fluctuations in magnetic fields.
GroznyAccording to the same seismology department, a major earthquake in the period from 2017 to 2036. may occur in the North Caucasus, on the border of Chechnya and Dagestan. Unlike the situation in Kamchatka, no work is being carried out there to reduce possible damage from earthquakes, which could lead to more human casualties than if such work had been carried out.
New YorkNew research results from American seismologists from Columbia University indicate a high seismic hazard currently in the vicinity of New York. The magnitude of the earthquake can reach five points, which can lead to the complete destruction of old buildings in the city. Another cause for concern was the nuclear power plant located right at the intersection of two faults, i.e. in an extremely dangerous region. Its destruction could turn New York into a second Chernobyl.
Banda AcehIndonesia is located in the most seismically active zone on the planet, and therefore earthquakes here will not surprise anyone. In particular, the island of Sumatra constantly finds itself almost directly at the epicenter of tremors. A new earthquake, predicted by seismologists, with an epicenter 28 km from the city of Banda Aceh, which will occur in the next six months, will not be an exception.
BucharestA strong earthquake in Romania could be triggered by blasting of shale rocks carried out in the Carpathian Mountains region. Geophysicists from Romanian national institute They report that the epicenter of the future earthquake will be located there, at a depth of 40 kilometers. The fact is that work to search for shale gas in these layers of the earth can cause displacements of the earth’s crust and, as a result, earthquakes.

Vladimir Erashov
In recent decades, the greenhouse effect has become the talk of the town; it is blamed for the increase in all earthly disasters. But here's a sensational surprise - THE GROWTH OF THE GREENHOUSE EFFECT AND THE NUMBER OF EARTHQUAKES COINCIDED ONLY UNTIL 2005, THEN THE PATH diverged, THE GREENHOUSE EFFECT CONTINUED TO GROW, WHILE THE NUMBER OF EARTHQUAKES STARTED TO DROP SHARPLY. Moreover, the statistics of earthquakes are as follows, we will present them below, which does not leave the slightest doubt about the presence of the indicated trends. The number of earthquakes on Earth increased significantly until 2005, and then began to decrease significantly. Earthquakes in modern times are recorded by many tracking stations with great accuracy and very scrupulously. From this side, any error is excluded in principle. Consequently, the indicated trend is an indisputable fact, a fact that allows us to look at the problem of climate warming in a very unconventional way.
First, let's look at earthquake statistics: this statistic obtained after processing (summarizing) the daily number of earthquakes stored in the archive of the site http://www.moveinfo.ru/data/earth/earthquake/select
Let us clarify that the site stores earthquakes of magnitude four and above, starting in 1974. It has not yet been possible to process all the statistics, it is very labor-intensive, we present statistics for January earthquakes; for other months the picture is similar.
Here are the statistics:
1974 -313, 1975-333, 1976 -539, 1977 – 323, 1978 – 329, 1979 – 325, 1980 – 390, 1981 -367, 1982- 405, 1983 – 507, 1984 – 391, 1985 – 447, 1986 – 496, 1987 – 466, 1988 – 490, 1989 – 490, 1990 – 437, 1991 – 516, 1992 – 465, 1993 – 477, 1994 – 460, 1995 – 709. 1996 – 865, 1997 – 647, 1998 – 747, 1999 – 666, 2000 – 615, 2001 – 692, 2002 – 815, 2003 – 691, 2004 – 915, 2005 – 2127, 2006 – 971, 2007 – 1390, 2008 – 1040, 2009 – 989, 2010 – 823, 2011 – 1211, 2012 – 999, 2013 – 687, 2014 – 468, 2015 – 479, 2016 – 499.
And so in 2005 there was a radical change in the number of recorded earthquakes; if before 2005 the number of earthquakes, albeit with minor stops, only grew, then after 2005 it began to steadily decline.
Main conclusion:
The catastrophic increase in the number of earthquakes that occurred on Earth until 2005 greenhouse effect not connected in any way, it occurred for other reasons, these reasons remain to be determined.
An interesting fact is that in 2005, in parallel with the increase in the number of earthquakes, a radical change occurred in the speed of the Earth’s rotation; the Earth began to slow down its rotation. Now it is still impossible to state unequivocally that these facts are connected with each other, but it is also very unlikely that they coincided by chance. Moreover, short-term surges in the number of earthquakes correlate very well with surges in the Earth’s rotation speed.
From the works of scientist Sidorenkov N.S. It is known that the speed of rotation of the Earth has a very good correlation with the temperature on the Planet; a higher speed of rotation of the Earth corresponds to a higher average temperature - this has been established experimentally over a fairly long period of observations. Then a completely logical question:
Will a decrease in the Earth's rotation speed be followed not only by a decrease in the number of earthquakes, which has already followed, but also by a decrease in average temperature, that is, do not these factors signal us about the beginning of an era of cooling?
Apparently it is too early to put an end to this issue, but Russian science has no right to leave this issue without attention, the stakes are painfully high. Of course, no scientist will cancel the future cooling of the climate, which may be about to begin, but this cooling should not fall on Russia out of the blue.
In this regard, I ask readers not to be lazy, but also re-read the article “Transparent Climate”.
Isn't it time Russian science wake up?
24.05. 2016
The destructive power of an earthquake depends on its magnitude (at the hypocenter, i.e. at the source), the depth of the earthquake source and the distance from the epicenter (the point of projection of the source onto the surface of the earth).
Examples of media reports and explanations of terms:
“According to ***, there, at such and such Moscow time, an earthquake occurred magnitude in the outbreak M=4.3 points on the nine-point Richter scale, at a depth of 15 km from sea level.
The epicenter of the earthquake was located 100 kilometers southeast of the city ***. Tremors were felt in the village of *** by force up to four points, and in the city *** - three points (on a 12-point scale). According to the latest data, there are no casualties or serious damage. Over the course of a week, 4 earthquakes with a magnitude from 2.3 to 4.3 on the Richter scale were recorded in the indicated area, which were also felt in neighboring regions. According to statistics provided by seismologists, the average interval between series of earthquakes with a magnitude of up to four in this area is approximately *** years."
Or
“An earthquake with a magnitude of 4.3 at the source occurred there. Its epicenter was located one hundred kilometers southeast of the city ***. The depth of the source was 15 km” from sea level.
Or
The four-point earth happened today somewhere.
The magnitude of an earthquake (not to be confused with “strength”, and leave the points alone) - quantitatively characterizes its energy at the source, on a nine-point Richter scale (0-9). Calculated based on the results of measurements by instruments (seismographs) at the seismic stations closest to the epicenter different countries. An earthquake with a magnitude of 6.0 or higher, with a nearby epicenter and a shallow source, is considered strong and can cause significant destruction and lead to casualties among the population, especially if buildings and residential structures are not designed for proper seismic resistance or were built by low-skilled migrant workers, with rough violations of construction norms and rules.
The strength of earthquake tremors (intensity) is a qualitative (felt, visible) characteristic of the degree of destruction and other manifestations on earth's surface, at a specific point on the surface of the earth. For this, a twelve-point scale (1-12) or a modified Mercalli scale is used. They differ little. Real danger represent tremors with a force of four or more.
Forecast. Before a strong earthquake, a few minutes or even hours later, domestic animals and birds begin to scream and rush around, trying to run away from the house to the street, to hide. The dogs try to take their owners and children to a safe place. Cats carry kittens away. Aquarium fish- they are worried, trying to jump out of the water of the aquarium. Rats and mice are running outside from the basements of houses. Wild animals, in advance - several hours or days before the earthquake, leave the dangerous area in packs. Snakes and lizards crawl out of their holes (even in winter, at night and in bad weather), Birds constantly scream, fly in circles for a long time and randomly. Animals and birds lose their appetite, their behavior changes greatly - they, without attacking each other, move away from danger together.
Those who were born, raised and lived (in natural conditions) in earthquake-prone areas. The skill lasts a long time. Their reaction is more often selective, only to close (local earthquakes) and dangerous in strength (more than two to four points).
Seismologists and volcanologists use scientific, instrumental forecasting methods and early warning methods: constant monitoring seismic activity a network of sensitive sensors, regular measurements and detection of increases in the concentration of helium and radon in surface air and at depth, etc.
Dependence of earthquake intensity. from the distance to the epicenter. From nearby earthquake epicenters great strength(if a “seven” magnitude strike or higher) - very sharp shocks and impacts, intense shaking are felt, glows and sparks are visible, an underground rumble, crackling and roar of collapsing buildings and falling, broken trees are heard, a sharp increase in wind occurs. At distances of hundreds of kilometers from the epicenter, echoes of an earthquake reach - low-frequency, relatively slow vibrations, wave-like swaying of the daytime surface of the earth. The farther away, the smaller their vertical amplitude and longer period(up to a minute or more, at a distance to the epicenter of several thousand kilometers), with the exception of anomalously intense and resonant manifestations at certain distances from the epicenter and along large, deep tectonic faults.
Influence of tidal (gravitational) effects. Seismicity increases - during the new moon and, especially, during the full moon, as well as when the Moon is at perigee (closer to the Earth). There is also a seasonal dependence: in autumn and, especially, in winter, it shakes stronger and more often than in spring and summer.
Geological factor. The greatest damage from an earthquake occurs at rocky outcrops rocks and if they are covered with loose sediments of small thickness, which are thrown up at their base. Safer ground conditions are areas with thick layers of loose rocks. rocks in which the seismic wave weakens and is extinguished until it reaches the earth's surface.
Tsunamis occur when the earth's epicenter is near sea coast. At the first impact, the water first moves away from the shore, and then, accelerating, hits the coast in the form of a large wave. Glow brightness marine organisms- increases sharply two to three minutes before the tsunami.

World tectonic plate map
Scientists have compiled a map of the largest tectonic plates:
- Australian;
- Arabian subcontinent;
- Antarctic;
- African;
- Hindustan;
- Eurasian;
- Nazca Plate;
- Plate Coconut;
- Pacific;
- North and South American platforms;
- Scotia Plate;
- Philippine plate.
From theory we know that hard shell The earth (lithosphere) consists not only of plates that form the relief of the planet’s surface, but also of the deep part - the mantle. Continental platforms have a thickness from 35 km (in flat areas) to 70 km (in mountain ranges). Scientists have proven that the slab is thickest in the Himalaya region. Here the thickness of the platform reaches 90 km. The thinnest lithosphere is found in the ocean zone. Its thickness does not exceed 10 km, and in some areas this figure is 5 km. Based on information about the depth at which the earthquake epicenter is located and the speed of propagation of seismic waves, the thickness of sections of the earth’s crust is calculated.
Map of faults and seismically dangerous placesThe map shows the locations of seismically hazardous zones. The zones are highlighted in color - from green to red. The closer the color is to red, the higher the likelihood of strong and destructive earthquakes. The map was created using data from earthquakes that occurred since 1973.
Nuclear power plants are shown on the map. Finding nuclear power plant in a seismically dangerous zone increases the danger to the population.

Earthquake map from quakes.globalincidentmap.com Earthquake map from emsc-csem.org Behavior before, during and after an earthquake|
The vast majority of earthquakes last about one, rarely more than one minute. However, the intensity of the oscillations during this time is not the same. As a rule, an earthquake begins with relatively weak vibrations (sometimes imperceptible), which last 10-20 seconds, then the main phase of the earthquake begins, in which the vibrations reach their greatest intensity, then a gradual decline follows. Well-constructed and well-maintained buildings, which do not have special anti-seismic measures, can withstand earthquakes of up to magnitude 6 without much damage. Buildings in unsatisfactory technical condition and dilapidated, under threat strong earthquakes doubly dangerous. Before the earthquake Inside your home, firmly attach cabinets, shelving, and cabinetry to the walls and floor. Furniture, standing and hanging objects in residential premises are placed so that if they fall, the sleeping persons will not be injured and the passages and exits from the apartment will remain free. All heavy objects should be moved to lower shelves and places. Shelves with dishes must be closed. Attach chandeliers and overhead lights securely; do not use glass shades. Do not block passages and exits from rooms and apartments with things. Flammable, caustic, toxic liquids and powders must be securely sealed, closed in strong, secured containers and boxes. All family members should be well aware of the most important dangerous places residential premises: in the openings of internal main walls near these walls, at supporting columns and under frame beams, in the corners of internal main walls and under durable furniture (tables, beds). And dangerous places too: near large glazed openings and partitions, corner rooms of buildings, especially the top floors. During an earthquake Don't panic! Quickly focus on executing previously thought-out actions, but be prepared to act according to circumstances. In the house/apartment: If you are in a low building, up to 2-3 floors, then it is better to leave it quickly. Moreover, this should be done if the building is not earthquake-resistant. Run out quickly but carefully, beware of falling objects, downed wires and other sources of danger, and immediately move away from the building to an open area. When on the upper floors of a multi-story building, do not rush towards stairs or elevators. Most likely, they will be crowded with people and the elevators will be disabled. Therefore, it is better to stay in the building and, after opening front door, which in the future may become jammed from distortions, quickly take the safest place in the room: under durable furniture, at the support column wall closest to the center of the building, in the doorway of the main walls, in the corner of the room. And always away from windows, heavy objects and equipment that could tip over. Provide assistance to the disabled and elderly. Do not enter or run around buildings. Once near a tall building, stand in the doorway, this will protect you from falling pieces of glass, balconies, cornices and parapets. It's best to be on open place, away from buildings and power lines. In transport Any vehicle must be stopped calmly and quickly, as far as possible from tall buildings, overpasses, bridges, power lines or anything that could collapse from strong shocks. Bus and tram drivers must open all doors after stopping their transport. After the earthquake While in the building, remain calm and assess the situation. Examine yourself and the people nearby, and if necessary, provide medical care those in need. Wear sturdy shoes to avoid damaging your feet from splinters and debris. When going down the stairs, check the reliability of its structures. Check for fire hazards. Any fire that occurs must be extinguished immediately. If you notice damage to electrical wiring, turn off the power if you have not already done so. Based on materials from the State Committee of the Republic of Buryatia
