Megatsunami in Alaska fjord became the second highest in history

A huge megatsunami wave that originated last summer in a remote fjord in southeastern Alaska has become the second highest in the history of observations. This was reported on May 6 by the BBC television and radio company.

"The huge wave is the second-tallest wave ever recorded and is a reminder of the risks associated with melting glaciers," the publication says.

According to scientists, a series of small earthquakes triggered a powerful landslide: about 64 million cubic meters of rock fell into the water in less than a minute, causing a wave almost 500 m high. The highest megatsunami in history was recorded in the 1950s, when the wave height exceeded 500 m.

The researchers note that this time it was possible to avoid casualties largely due to the time of the incident.: The incident occurred in the early morning, when the tourist ships had not yet entered the Tracy Arm fjord, which is popular among travelers.

On April 20, an earthquake of magnitude 7.4 occurred in Aomori Prefecture in northern Japan. Then the authorities declared a tsunami threat. The peak wave height reached 3 m. Meteorologists warned that the next waves would be higher and urged not to approach the coast. Later, a second 80 cm high wave reached the port of Kuji in the same prefecture.
