In Greek mythology, Poseidon was the cause and god of earthquakes. When he was in a bad mood, he struck the ground with a trident, causing earthquakes and other calamities. He also used earthquakes to punish and inflict fear upon people as revenge. [86] In Japanese mythology, Namazu (鯰) is a giant catfish who causes earthquakes.
An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is ...
Movement of tectonic plates against each other sends seismic waves rippling across earth’s surface
Following an earthquake event, S waves arrive at seismograph stations after the faster-moving P waves and displace the ground perpendicular to the direction of propagation. Depending on the propagational direction, the wave can take on different surface characteristics; for example, in the case of horizontally polarized S waves, the ground ...
A major earthquake measuring 7.4 hit Taiwan early Wednesday, killing 9 and injuring at least 1,000. A 7.4 earthquake is exponentially more destructive than the 4.8 quake that struck central New ...
October 15, 2020, an earthquake swarm occurred on the island of Panay ranging from magnitudes 2.5-4.5. Most of these quakes felt in Iloilo City. [11] A previous swarm also hit Panay on November 5, 2018 (Including Antique, Iloilo and Guimaras) ranging from magnitudes 4.0-4.8. The first earthquake (magnitude 4.7) at 7:45 A.M, occurred at San Jose ...
In the event of an earthquake, they need to stop the reaction as quickly as possible. ... and finally, when those quakes hit, how much shaking they cause. Earthquakes account for about 65% of the ...
