Lituya Bay is hit by a mega-tsunami. At 10:15 p.m. an earthquake with a magnitude of 7.9 struck the Lituya Bay area, which is still daylight for Lituya Bay during that time of year.

The tide was ebbing at about plus 1.5m and the weather was clear. Anchored in Anchorage Cove, near the west side of the entrance of the bay, Bill and Vivian Swanson were on their boat fishing when the unthinkable happened, the wave is recorded at 524 meters high, making it the largest wave in history, 470 feet taller than the Empire State Building.

Eyewitness account refer that: With the first jolt, I tumbled out of the bunk and looked toward the head of the bay where all the noise was coming from. The mountains were shaking something awful, with slide of rock and snow, but what I noticed mostly was the glacier, the north glacier, the one they call Lituya Glacier. Read More…

The epicenter was located 125 kilometers east-southeast of Cruzeiro do Sul, Brazil, 330 kilometers east of Pucallpa, Peru, 460 kilometers south-southwest of Tabatinga, Brazil, and 2700 kilometers west-northwest of Brasilia, Brazil.

A civil defence service spokesman in Cruziero do Sul reported to Times Live that the quake was unnoticed. “This zone suffers a lot of earthquakes, but the last one we really felt was 20 days ago. We didn’t register any disorder or damage on the surface,” he said.

“Generally speaking, quakes more than 500 kilometres deep don’t leave signals in the surface, they are only detected by instruments,” said an official of Brazil’s Seismological Observatory to AFP.

A devastating earthquake (measuring around 8.0 magnitude) occurs in Sichuan, China, killing over 69,000 people, less than three months before China hosted the world in the 2008 Summer Olympics.2008_Sichuan_earthquake_map

The epicenter was 80 kilometres (50 mi) west-northwest of Chengdu, the capital of Sichuan, with a depth of 19 kilometres (12 mi).

The earthquake was also felt in nearby countries and as far away as both Beijing and Shanghai — 1,500 kilometres (932 mi) and 1,700 kilometres (1,056 mi) away — where office buildings swayed with the tremor.

Approximately 15 million people lived in the affected area. It was the deadliest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people, and the strongest since the 1950 Chayu earthquake in the country, which registered at 8.5 on Richter magnitude scale. It is the 19th deadliest earthquake of all time.

Strong aftershocks, some exceeding magnitude 6, continue to hit the area even months after the main quake, causing new casualties and damage.
