The Tohoku Earthquake

The Japanese Disaster

By Lauren Co

The 2011 Disaster

On March 11, a magnitude-9.0 earthquake struck the coastline of Honshu, Japan and it started on a Friday at 2:46 p.m. local time. It was centered on the seafloor 45 miles (72 kilometers) east of Tohoku, at a depth of 15 miles (24 km) below the surface. The shaking lasted about six minutes.

The Cause

  • Honshu, Japan lies on the intersection between the Eurasion and Philippine Plate.

  • The oceanic crust of the Pacific plate is converging with the Eurasion and Philippines plate and it subducts beneath the continental crust of Japan. As the plates converge, the plates buckle up and creates presssure and stress along the boundaries. That stress gets realesed and causes the earthquake.

  • This earthquake happened along a subduction zone.

The Aftermath

  • About 16,000 people were killed and 2,500 people were reported missing.
  • Less than an hour after the earthquake, a 39-meter (127 feet) Tsunami was unleashed. The Tsunami traveled 6 miles inland and flooded approximately 217 square miles.
  • The Tsunami also caused a Nuclear Meltdown at the Fukushima Daiichi Power Plant.
  • More than 120,000 buildings were destroyed, 278,000 were half-destroyed and 726,000 were partially destroyed.
  • The direct financial damage from the disaster is estimated to be about $199 billion dollars. The total economic cost could reach up to $235 billion

Fun Facts and extra info

  • It is the fourth largest earthquake in the world.
  • It is the costliest natural disaster in world history
  • The earthquake shifted Earth on its axis of rotation by redistributing mass
  • The jolt moved Japan's main island of Honshu eastward by 8 feet
  • Japan gets 1,500 earthquake per year

What scientists found

  • Scientists drilled into the subduction zone soon after the earthquake and discovered a thin, slippery clay layer lining the fault. The researchers think that this clay layer allowed the two plates to slide an incredible distance, some 164 feet (50 meters), facilitating the enormous earthquake and tsunami.

  • When scientists are predicting earthquake, their predictions are based on the frequency of earthquakes at a given point, and when the most recent quake has occurred.
