Massive 7.8 Magnitude Earthquake Triggers Tsunami Warning for Pacific Coasts – A powerful tremor of quantity 7.4 struck in the northern Pacific Ocean between the tip of Alaska’s Aleutian Islands and Russia’s Kamchatka Peninsula, the U.S. Geological Survey said on Monday.
The quake struck at 1:34 a.m. on Tuesday( at 2334 GMT on Monday) some 125 miles( 200 km) from the towns of Nikol’skoye on Bering island off the Kamchatka Peninsula. The epicenter was west of Attu, the westernmost and larger island in the Near Islands group of Alaska’s remote Aleutian Islands.
The earthquake, first reported as a quantity 7.7, was highly shoal — exclusively 7.4 miles( 10 km) below the seabed, which would have amplified its gist, but it was quite far from any mainland.
tsunami billows are probable for sea-coasts located within 300 km( 186 miles) of the earthquake epicenter .”
Tsunami billows, however, were unlikely to reach Kamchatka’s eastern coast, some 500 km( 310 miles) away.
The quake was followed by various aftershocks, including a duet above quantity 5.0.
