India, July 30 -- Tsunami warnings have been issued in Russia, Japan, Ecuador and Hawaii after a massive magnitude earthquake struck off Russia's far eastern coast Wednesday.

An earthquake of 8.8 magnitude, which hit Russia's Kamchatka Peninsula at about 11:25 AM local time, is the sixth most severe quake in history, according to the US Geological Survey.

The first waves triggered by the massive earthquake have reached Hawaii, with a 4 foot wave recorded off Oahu.

Sirens and phone alerts reportedly blared across Maui.

Evacuation warnings have been issued to people in Hawaii, parts of the US west coast and Japan within hours of one of the strongest earthquakes in recent history hit the Russian coast.
