What Causes Earthquakes?
There are three types of earthquake waves: primary waves (P-waves), which are compressional and move the fastest; secondary waves (S-waves), which are transverse and slower than P-waves; and surface waves, which are the slowest and cause the most damage. Earthquakes are caused by the movement of tectonic plates and are measured using the Richter scale, which takes into account the magnitude and intensity of the shaking at a particular location.
The 10 Deadliest Earthquakes in Human History
Earthquakes are one of the most destructive natural disasters that can occur, and throughout history, there have been many earthquakes that have caused widespread damage and loss of life. Some of the deadliest earthquakes in history include the Great Kanto Earthquake of 1923 in Japan, which resulted in the deaths of over 140,000 people, and the Tangshan Earthquake of 1976 in China, which resulted in the deaths of over 240,000 people.

These earthquakes all caused widespread damage and loss of life, and their impact is still felt today.
Where Does Earthquake Data Come Form?
Earthquake data is collected and analyzed by a variety of organizations and agencies around the world, including the USGS, EMSC, CEA, and JMA. It is used for the development of earthquake early warning systems, the creation of earthquake hazard maps, the assessment of earthquake risk, and the study of earthquakes by scientists.
How do I prepare for the next earthquake?
To prepare for an earthquake, it's important to make a plan, secure your home, assemble an emergency kit, learn how to turn off utilities, and stay informed. These steps can help protect you and your family in the event of an earthquake and ensure that you are prepared to respond appropriately.
Tips to Prepare Your Home for An Earthquake
To make your home earthquake ready, you should secure heavy objects, brace water heaters, check gas appliances, install shatterproof glass, keep emergency supplies on hand, and have an evacuation plan. By taking these steps, you can protect your family and property from the dangers of an earthquake.
