What are the levels of earthquakes.

In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake. The amount of energy released increases 31.7 times between whole number values. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.Question 1138533: The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log(I1/I2)= M1 - M2 where M is the magnitude given by the Richter scale. An earthquake of magnitude 6.9 hit a city.A 2004 HAZUS report prepared by FEMA, based on a 7.7 earthquake occurring in the New Madrid Seismic Zone, estimates earthquake damages to be $296 billion dollars across the region and nearly 730,000 people displaced from their homes.

Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis. The extent of destruction and harm caused by an earthquake depends on: the risk ...

A megathrust earthquake is where one tectonic plate slips beneath another, causing vertical motion of the plates. This large vertical displacement of the sea-floor generated the devastating tsunami, which caused damage over such a large area around the Indian Ocean. The earthquake was also unusually large in geographical extent.
