Well, seismic waves travel different depending upon the underlying geology of an area. If you take the Haiti earthquake of 2010 for example, the epicentre was into the mountains within Haiti, and it is reported that buildings were still standing, yet a few kilometres away, as you reach lowland areas, houses were seen to be completely flattened. Usually, most destruction is at the epicentre itself, but this wasn't the case in the Haiti earthquake, because of the mountainous terrain and the hard rock beneath in the underlying geology. In the areas where total collapse was seen, the underlying geology was mainly composed of soils, allowing more damage to occur from the seismic waves.

How is the distance from the epicenter related to the amount of earthquake damage?

The more energy, the more damage it can cause.


Which of the following can cause damage days or month after a large earthquake?

Aftershocks, landslides, liquefaction, and tsunamis can all cause damage in the days or months following a large earthquake. Buildings weakened by the initial earthquake may collapse due to aftershocks, while unstable terrain can lead to landslides. Liquefaction can cause the ground to become soft and unstable, and tsunamis can result from undersea earthquakes, posing a threat to coastal areas even after the initial seismic event.


What kind of damage can a 0.7 earthquake cause?

None at all. A magnitude 0.7 earthquake would be an instrumental earthquake, meaning it can be picked up on seismometers, but otherwise is not noticeable.


Which earthquake fault cause the most damage strike slip reverse or normal?

The amount of damage caused by an earthquake fault does not depend on the type of fault (strike-slip, reverse, normal). The severity of damage is mainly influenced by factors such as the magnitude of the earthquake, the depth of the focus, the distance from populated areas, and the building codes in place.


Are earthquakes cause more damage near the epicenter?

Yes, earthquakes typically cause more severe damage near the epicenter because the energy released decreases as you move away from the epicenter. The intensity of shaking and resulting damage decreases with distance from the source.
