Tohoku Earthquake

In March 11th, 2011, the Tohoku earthquake (Great East Japan) occurred in 2:46 JST. It lasted for six minutes with an 45mi epicenter and 20 mi hypocenter that were enough to damage many cities along the east coast of Japan. The earthquake undersea created tsunamis over ten meters in height leaving many people dying, missing, and injured. The magnitude first measured to be 8.9, but later said to be 9.0.
It wasn't only the earthquake and tsunami that devastated Japan. The earthquake and tsunami also damaged the rods in the Fukushima nuclear power plant which led to the release of harmful nuclear materials airborne and through the ocean. Japan told its residents around 20 km radius to evacuate while the U.S. told its citizens to evacuate from 80 km radius. The nuclear materials led many organisms' genetics to mutate, leading to deforms.

The earthquake moved Honshu 2.4m east and even shifted the Earth axis by 10cm. It's fairly noticeable why this is the fourth larges earthquake ever recorded.
