What effect would a 9.8-magnitude earthquake have at a depth of 5 km below Tokyo?
A magnitude 9.8 earthquake at a depth of 5 kilometers beneath Tokyo would be a catastrophic event that could cause widespread destruction and significant loss of life, according to the U.S. Geological Survey (USGS).

The shaking intensity would depend on several factors, including the location of the epicenter, the thickness of the Earth's crust, and the type of soil and rock in the area. However, based on current knowledge about earthquakes and their effects, a magnitude 9.8 earthquake at a depth of 5 kilometers beneath Tokyo would likely result in severe damage to buildings, infrastructure, and natural resources, as well as potentially cause tsunamis and other coastal impacts.

It is important to note that the impact of an earthquake can vary greatly depending on its location and severity, so it is essential to take preparedness measures and seek professional advice if you live near a potential seismic zone or are planning to travel outside of Japan during a major earthquake.
