Earthquakes involve the powerful movement of rocks in the earths crust. The rapid release of energy creates seismic waves that travel through the air.The earthquakes seismographers used to measure the magnitude of earthquakes. You are unlikely to feel a magnitude 3 earthquake but a magnitude 6 earthquake could potentially cause large damage.The damage caused by earthquakes also depends on their depth and fault type.
The earthquake that hit the Tohoku region of Japan on March 11, 2011, had a magnitude of 9.0 and killed over 15000 people.
- The destruction caused by the Hokum earthquake was made much worse by powerful tsunamis that were triggered due to the earthquake’s epicenter being located offshore.The 2004 earthquake that occurred in the Indian Ocean near Sumatra, Indonesia triggered a series of tsunamis that killed over 200000 people in 14 countries.
