Earthquakes and Disasters

The primary cause of an earthquake is the movement of tectonic plates in the Earth's crust.

Earthquake Prone Regions

Certain states, such as California, Oregon, and Washington, are more prone to a higher frequency of earthquakes due to their location on the Pacific Ring of Fire.

Global Earthquake Frequency

Thousands of earthquakes occur around the world every day, with a significant number going undetected.

U.S. Geological Survey Report (2015)

The U.S. Geological Survey reported in 2015 that several million earthquakes occur globally every year, with over a million of them strong enough to be felt by people.

Post-Earthquake Activity

Aftershocks, which are smaller earthquakes that continue to occur, can happen for months after an initial earthquake.

Disaster Severity Factors

The main factor that determines the severity of damage caused by a natural disaster is the vulnerability of the affected population.

Rethinking 'Natural Disasters'

Scholars suggest replacing the term 'natural disaster' with 'socio-natural disaster' to recognize the interplay between natural and human factors.
A disaster occurs when a natural hazard coincides with vulnerable populations, leading to devastating consequences.
The primary cause of a disaster lies in the vulnerable human populations, rather than the natural event itself.
