Earthquakes around the world


According to initial information, the epicentre of the earthquake was near the India-Nepal border. The earthquake was measured at magnitude 5.0 on the Richter scale.

The US agency, in its assessment, also said that the epicentre of the earthquake was located just 1.3 km below ground.

There were no immediate reports of casualties or damage due to the earthquake Tuesday evening.

Second in a Day: 5.4-Magnitude Earthquake Strikes Off the Coast of Mexico's Chiapas - USGS
20.11.2019
Earlier in the day, a 6.3 magnitude earthquake struck off the coast of Mexico's southern state of Chiapas.

A 5.4 magnitude earthquake struck 119 kilometres south-west of the municipality of Suchiate, the US Geological Survey (USGS) reported.

According to the USGS, the quake occurred at a depth of 10 kilometres.


The tremor occurred at 11:30:56 (UTC).

There are no immediate reports of any casualties or damage caused by an earthquake.
 
From Natural News:
How is a massive “blob” of rock causing earthquakes in Central Asia?

Far beneath the Hindu Kush mountains of Central Asia, a giant blob of continental rock is slowly dripping away from the lithosphere into the mantle below. A recent study attributed many of the deepest earthquakes in the region to the movements of this blob.

The Hindu Kush runs for hundreds of miles and straddles the border of Afghanistan and Pakistan. It is one of the most seismically active areas in the world.

Every year, the mountain range gets rocked by more than 100 earthquakes that measure a magnitude of 4.0 or higher. It also experiences many intermediate-depth quakes that happen between 45 to 190 miles (70 to 300 kilometers) below the surface.

Until recently, experts didn’t know why the Hindu Kush suffers so many earthquakes at intermediate depths. The mountain range doesn’t sit on top of a significant fault line, which any California resident knows causes numerous earthquakes.

Further, the mountains are some distance away from the ongoing collision between the Eurasian and Indian tectonic plates. Therefore, the usual candidates for the cause behind constant earthquakes are absent from the area. (Related: Fracking-induced earthquakes in Central and Eastern America are on the rise, caution researchers.)

Researchers from the University of Montana (UM) and the University of Colorado (UC) Boulder recently published their findings on the Hindu Kush quakes. They reported that a long blob in the lithosphere might be causing the tremors above it.

The anomoly formed when molten rock dripped from the underbelly of the mountain range and into the hot, viscous mantle beneath it. The resulting blob resembled a water droplet moving away from the faucet.

The blob of molten rock is located 100 miles (150 kilometers) beneath the surface. It might be falling away from the lithosphere at speeds as fast as four inches (10 centimeters) annually.

The immense stress caused by the movement of that massive blob of rock might be what triggers the earthquakes in the Hindu Kush.

The researchers spent several years gathering data on earthquakes near the mountain range. They deduced the existence of the subterranean blob, as well as another curious matter.

Quakes that appear in most seismic zones tend to follow a lineament, an obvious path. For example, many earthquakes follow the San Andreas Fault in California — which is why some refer to the fault as a “megalineament.”

The observational data showed that the Hindu Kush earthquakes followed a different pattern of appearance. UM researcher Rebecca Bendick remarked that these quakes formed a round patch of seismic activity on the surface.

Further, the earthquakes also formed along a distinct vertical axis. The quake-prone area started between 100 and 140 miles (160 and 230 kilometers) beneath the continental plate.

Finally, the earthquakes most commonly formed deeper down. At those depths, the solid rock of the continental crust met the hot and molten material of the upper mantle.

The researchers noted that the stretching blob of molten rock experienced the greatest structural stress around those depths as well.

The UM and UC Boulder study lent credence to the existence of a massive, dripping blob of solid rock beneath the Hindu Kush. A different study brought up the possibility of another blob existing beneath the Carpathian Mountains in central Europe, where similar seismic activity also took place.

The blob might have started falling from the continental crust no earlier than 10 million years ago. It dripped downward faster than the movement of the Indian and Eurasian tectonic plates that bore the Hindu Kush mountains.

The findings suggest that tectonic plate movements were not the only possible source of earthquakes. Other geophysical forces — even ones as strange as giant blobs of rock — might also cause the ground to shudder.

 
According to Terry Remple, the big one is coming in a very very near future.
Just now listening to the rest of this - I'm up to "the 200 trillion tons of liquid carbon that has accumulated ... that is exceptionally volatile compared to regular magma". Couldn't help but think of Greta when I heard this.

Cs indicated it's coming and scientists have, too. My son's best friend and his family are in Seattle area, his two brothers-in-law and families in Portland, OR and Los Angeles, CA. Would they heed a warning about this very real, very possible catastrophic rupture/tsunami that may be imminent? Hard to know. What's for sure is gas lines/water lines/electrical lines will all be broken/downed with fires everywhere and roads impassable due to massive destruction. And then the sea will rush in . . .

Even if evacuation started now, could everyone make it to a safe area? And that's if you're dealing with basically sane, cooperative people - seemingly in somewhat short supply in these states. The prospect of this happening is really quite terrifying!

Amazing that the M 4.8 - is still a buzz with speculation.

An uncommonly shallow temblor rattled the country, sending scientists buzzing as they began hunting down its source.

Fears of explosions at the nearby nuclear energy plant flooded into his mind. Bastie, a high school biology and geology teacher, rushed outside expecting to see the bloom of a mushroom cloud. But as he soon discovered, the shaking came from something less devastating but still surprising for the region: an earthquake that cracked through the ground.

Update:
And this one of 6.4 was felt all over the Balkan peninsula. It was a pretty strong felt in the western part of Macedonia. It woke me up at 4:00 am. We were all very upset at home. Then there was another one at around 7:00 am and it was not so strong as the first one. And also there were a lot of smaller aftershocks. Some of them were also felt in Macedonia.
