What was the biggest tsunami?
1958 Lituya Bay earthquake and megatsunami
In a total of 43 tidal waves classified as a tsunami since 1562 a total of 6,644 people died in Chile. Tsunamis therefore occur comparatively often in this country. The strongest tidal wave registered in Chile so far reached a height of 50 meters.
In Chile, large earthquakes through recent history occur roughly every 25 to 100 years apart. The strongest earthquake ever recorded by modern instruments was a 9.5-magnitude quake on May 22, 1960, which was centered offshore in southern Chile, where it set off a huge tsunami.
Authorities issued a tsunami warning for Japan on Saturday after a magnitude 7.2 earthquake struck off the coast of Miyagi prefecture. Tsunami waves of up to 1 meter (3.2 feet) hit land shortly after the earthquake, local television channel NHK reported.
On May 22, 1960, at 19:11 GMT, an earthquake occurred off the coast of South Central Chile. A Pacific-wide tsunami was triggered by the earthquake, which had a surface-wave magnitude of 8.6, an epicenter of 39.5° S, 74.5° W, and a focal depth of 33 km.
earthquakes in Chile. Chile is located on a tectonic plate boundary and a subduction zone called the Peru-Chile trench. A subduction zone is where the ocean crust slides under the continental margin which causes compressional deformation (mountain building), earthquakes and volcanoes.
How many people died in the 2004 tsunami?
Most tsunamis are generated by shallow earthquakes in subduction zones, since those are the commonest earthquakes which distort the seafloor. These subduction zones are both smaller and much less active the subduction zones that circle the Pacific, so the Atlantic has many fewer tsunamis.

Specialist incidents. Over 50 countries including Brazil, the People's Republic of China and Argentina gave aid to Chile after March 1, 2010.
The earthquake that rocked Chile in 2010, one of the largest in history, measured a magnitude of 8.8. The ensuing damage wiped out roughly 18% of the country's GDP. Yet the country demonstrated a miraculous recovery. Chile's recovery is all the more astonishing because it is so atypical.
The Chilean earthquake occurred on February 27, 2010. It registered 8.8 on the moment magnitude scale. The earthquake was caused by the Nazca and South American Plates converging. Thrust-faulting by the South American Plate as it overrides the Nazca Plate created the megathrust earthquake.
Football is the most popular sport in Chile, and is played for a range of reasons. However, the country's most successful sport is tennis. In rural areas, Chilean rodeo is the most practiced sport in Chile, which is the national sport.
April 18, 1906: A M7. 8 earthquake hit San Francisco, California at 5:12 AM. This is by far the deadliest earthquake in U.S. history, initially recorded at 700 deaths (which still exceeds number two), now it suspected that 3,000 people lost their lives from the earthquake and aftermath that ensued.
When was the big earthquake in Chile?
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
The Great Tangshan Earthquake (northwestern China)The death toll, thought to be one of the largest in recorded history, was officially reported as 242,000 persons, but it may have been as high as 655,000.

After being hit by the planet's largest-ever recorded earthquake back in 1960, Chile developed strict anti-seismic building codes. Building codes were updated so structures could better withstand seismic waves.
The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake†in its own right.
