Niigata earthquake
The Niigata earthquake of June 16, 1964 had a magnitude of 7.5 and caused severe damage to many structures in Niigata. The destruction was observed to be largely limited to buildings that were founded on top of loose, saturated soil deposits. Even though about 2000 houses were totally destroyed, only 28 lives were lost (General report on the Niigata earthquake 1964). A tsunami, triggered by movement of the sea floor associated with the fault rupture, totally destroyed the port of Niigata.
The death toll of this earthquake was over 200. The Niigata earthquake has been extensively studied by Japanese seismologists, and in particular, by Keiiti Aki who introduced the concept of seismic moment, estimated its value for the Niigata earthquake based on spectral analysis of its seismic waves, and discussed the significance of seismic moment as a source parameter. This earthquake archive is created 
to honor Prof. Keiiti Aki for his many pioneering contributions in seismology.
Liquefaction The Niigata earthquake, together with the Alaska earthquake also of 1964, brought liquefaction phenomena and their devastating effects to the attention of engineers and seismologists. A remarkable ground failure occurred near the Shinano river bank where the Kawagishi-cho apartment buildings suffered bearing capacity failures and tilted severely (left). Despite the extreme tilting, the buildings themselves suffered remarkably little structural damage.

Sand boils and ground fissures were observed at various sites in Niigata. Lateral spreading caused the foundations of the Showa bridge to move laterally so much that the simply supported spans became unseated and collapsed
On 16 July 2007, a strong earthquake struck northwestern Japan, causing a fire and minorradioactive water leak at one of the world's most powerful nuclear power plants. At least seven people were killed and hundreds injured. Japan's Meteorological Agency measured the quake at 6.8 on the richter scale and sending aftershocks of 6.6. The U.S. Geological Survey, which monitors quakes around the world, said the initial quake registered 6.7. A tsunami watch was issued along the Sea of Japan. The predicted height of the tsunami was estimated to be 50 cm (20 inches). That earthquake sparked only a few small tsunamis, growing to be no more than about 20 cm (8 inches) tall. However, the 1964 quake and tsunami north of the current one destroyed the port of the city of Niigata
Natural Disasters
The Challenger Accident
The disaster happened in the 1968, when the American space shuttle, Challenger, has exploded killing all seven astronauts on board. They were five men and two women - including the first teacher in space - were just over a minute into their flight from Cape Canaveral in Florida when the Challenger blew up. The astronauts' families, at the airbase, and millions of Americans witnessed the world's worst space disaster live on TV.
The danger from falling in an unknown place prevented rescue boats reaching the scene for more than an hour.
President Ronald Reagan has described the tragedy as "a national loss".
The Challenger's flight, the 25th by a shuttle, had already been delayed because of bad weather. High winds, then icicles caused the launch to be postponed from 22 January.
EXTRAS:
In 25 years of space exploration seven people have died - today that total has been doubled.
The shuttle crew was led by Commander Dick Scobee, 46. Christa McAuliffe, 37, married with two children, was to be the first school teacher in space - picked from among 10,000 entries for a competition.

NATURAL DISASTERS
THE HURRICANE “DEAN”.
Hurricane Dean could become a Category Five hurricane later today before hitting Mexico, the US National Hurricane Centre said on Monday. The hurricane is expected to hit Mexico's Yucatan peninsula after having battered Jamaica's southern coast during a Caribbean rampage that has killed at least nine people.
Dean is currently an "extremely dangerous" Category Four hurricane, the second highest on the five-step Saffir-Simpson scale.
According to the hurricane centre, Dean is travelling at 33 kilometres per hour and carrying sustained winds of 240 km/h. The storm has passed more than 160 km to the south of the Cayman Islands – a British territory in the western Caribbean.
Jamaican authorities said 300,000 people were displaced by the storm, and at least one man was missing. Jamaican Prime Minister Portia Simpson Miller has declared a month-long state of emergency.

EARTHQUAKE IN PERU
The 8.0 magnitude quake that struck the coast of Peru on August 15 killed at least 500 people and left tens of thousands homeless. In a vast disaster area surrounding the cities of Pisco and Ica, the survivors, many of them living on the streets, are now desperately waiting for help. Over 34,000 houses were destroyed by the quake and several powerful aftershocks. The damage to the infrastructure is so severe that many relief efforts are hampered and remote mountain communities are cut off from assistance.The quake struck about 600km south-east of the Peruvian capital Lima at 1533 local time (2033 GMT) Chile and Bolivia also felt the earthquake. In northern Chile, 30 people were injured,four of them seriously.

Operations have also been hampered by a series of aftershocks, with many people worried about returning to their houses. Peru was battered by a strong 7.7 magnitude tremor in 1970 that killed approximately 70,000 people.

Natural disasters
The atomic bombings of Hiroshima and Nagasaki were nuclear attacks during World War II against the Empire of Japan by the United States of America
The United States Department of Energy estimates that, at Hiroshima, the death toll from the immediate blast was roughly 70,000, with additional deaths occuring in the time soon after the explosion and in the decades that followed
