The 2011 Japan Tsunami

About Tsunamis

Tsunamis are a massive sea wave that is usually caused by an earthquake. It is a displaced disproportionate amount of water that usually hits land and does damage. This gigantic seismic sea wave is caused primarily from earthquakes but also landslides, meteorite collisions, and volcanic activity. They occur due in oceans after some dramatic disturbance above or below the water.

About Tsunamis (continued)

Tsunamis can be predicted via drawbacks in the waves. If the drawback is large than the upcoming wave will be too. Unfortunately, a tsunami cannot be predicted accurately even if the seismic activity is known. Therefore when seismic activity is known then a tsunami warning is issued. On the coast, buoys detecting tide height will let scientists know if a tsunami is coming however it is not long until a tsunami comes usually only 30 minutes after the earthquake so a way to know with more time is needed. People could be saved by studying animals and native peoples. This is because both are able to more accurately detect earthly vibrations from seismic activity and low frequency sounds of the tsunami itself. As technology advances, the severity of tsunamis can be more accurately predicted from models of the tide and earthquake. At home, if a Tsunami ever struck, one should immediately leave for higher ground--preferably for mountians or other places higher-up. However, if not possible, one should get one the roof of the house to maximize survival.

About 2011 Tōhoku Earthquake and Tsunami

At approximately 1-2 o'clock PM a 9.0 magnitude earth occurred 45 miles of the coast of Japan. An Upthrust of 6 to 8 meters were detected on the seabed off the coast. Shortly after, a tsunami ranging from 3 feet to 128 hit the Northeast coast of Japan doing incredible damage. Of the 13,135 casualties, 92.5% of them died by drowning. It is apparent most of the fatalities were directly related to the tsunami not the earthquake. In addition to deaths, the damage to the land and people was tremendous. Hundreds of villages and towns across the coast were completely decimated. The estimated cost of the disaster is tens of billions of dollars. If that wasn't enough, the country lost massive amount of industry and its dams, water access, electricity, and gas network was badly damaged. Most notoriously, the Fukushima nuclear plant was damaged and emitted toxic radiation.

3 Interesting facts

1. None of Japan's wind power was damaged due to the disaster. Even though the ones directly hit by the tsunami.

2. In April 2015, police found debris spouted into the sea in Oregon.

3. The tsunami hit all the way in Australia, California, Argentia even hitting Antarctica.
