A computer-calculated earthquakes through-time display by Dr. A Jones, as of June 2012

An earthquake is the perceptible shaking of the surface of the Earth, resulting from the sudden release
of energy in the Earth's crust that creates seismic waves. Earthquakes can be violent enough to toss
people around and destroy whole cities. The seismic activity of an area refers to the frequency, type
and size of earthquakes experienced over a period of time.

Japan has had a long history of earthquakes and seismic activity. It is an area of high seismicity
because of its location near three major tectonic plate boundaries, and is situated on the Pacific Ring of Fire.

Most of the area was razed and made an urban renewal district.

The 2016 Kumamoto earthquakes are a series of earthquakes, including a magnitude 7.0 main shock
which struck on April 16, 2016 beneath Kumamoto City in Kyushu, at a depth of about 10 kilometres
and a foreshock earthquake with a magnitude 6.2 on April 14, 2016, at a depth of about 11 kilometres.
The two earthquakes killed at least 48 people and injured about 3,000 others in total.

Severe damage occurred in Kumamoto and Ohita Prefectures, with numerous structures collapsing and
catching fire. More than 44,000 people have been evacuated from their homes due to the disaster.

Japan Aftermath of the 2011 Tohoku earthquake and tsunami

The aftermath of the 2011 Tohoku earthquake and tsunami included both a humanitarian crisis and
massive economic impacts. The tsunami created over 300,000 refugees in the Tohoku region of Japan,
and resulted in shortages of food, water, shelter, medicine and fuel for survivors. 15,891 deaths have
been confirmed. In response to the crisis, the Japanese government mobilized the Self-Defence Forces,
while many countries sent search and rescue teams to help search for survivors. Aid organizations both
in Japan and worldwide also responded, with the Japanese Red Cross reporting $1 billion in donations.
The economic impact included both immediate problems, with industrial production suspended in many
factories, and the long-term issue of the cost of rebuilding, which has been estimated at 10 trillion yen
($122 billion). A further serious impact of the tsunami was the critical damage done to the Fukushima
Daiichi Nuclear Power Plant, resulting in severe releases of radioactivity and the prospect of a long-term
health and environmental hazard in need of an expensive clean-up.
