What are some examples of Earthquakes?
The Haiti earthquake was a magnitude 7.0 on the Richter SCALE, with an epicenter near Leogane, 25 km west of its capital, Port-au-Prince. It struck on January 12, 2010 where at least 52 aftershocks measuring 4.5 or greater could still be felt even 12 days later. The earthquake left a devastating wake of 316,000 deaths, 300,000 injured and 1,000,000 people homeless. It was estimated that 250,000 houses and 30,000 commercial buildings had collapsed or were severely destroyed.
On March 11, 2011, the east coast of Tohoku in Japan was struck by a 9.03 magnitude earthquake, which was the strongest to ever hit Japan. Considered one of the top five largest earthquakes in the world, it caused destruction that claimed 15,878 lives, left 6,126 injured and 2,173 people missing across 20 prefectures. It also caused the collapsed of 129,225 buildings, while the tsunami brought about by the quake also caused severe structural damages, fires in many areas, and damages in roads and railways. This was the most difficult crisis Japan had ever faced after World War II as it did not only inflict damages to lives and properties, but also caused significant damages to four major nuclear power stations. Debris from the tsunami reached as far as Canada and Hawaii.
