Tsunami Safety Guide: Warning Signs, Survival Tips, Dos And Don'ts

Tsunami alerts were issued across the Pacific after a massive earthquake rocked Russia's Kamchatka Peninsula. The 8.8-magnitude undersea quake sent waves up to four metres high into Russia's eastern coastline, setting off evacuations and warnings across the region. In Japan, authorities issued advisories in over 130 coastal towns, urging nearly nine lakh people to move to higher ground.

Tsunami watches were also issued in parts of the US, Canada, Mexico, and Hawaii. The waves that eventually reached Japan were much smaller than anticipated, measuring around 1 to 1.3 feet, and were observed in areas such as Hokkaido and Ishinomaki. No major damage has been reported.

What Is A Tsunami?

Tsunami means "harbour wave" in Japanese. It is a series of large sea waves caused primarily by sudden movements of the ocean floor, usually due to undersea earthquakes. Other causes can include volcanic eruptions, landslides, or even meteorite impacts.
