A powerful earthquake of magnitude 8.8 struck off Russia's far eastern Kamchatka Peninsula on Wednesday, triggering a Pacific Ocean tsunami warning. Destructive tsunami waves could reach areas along the coasts of Russia and Japan in the next three hours, according to the US Geological Survey (USGS).
The quake was shallow at a depth of 19.3 km (12 miles), and was centred about 125 km (80 miles) east-southeast of Petropavlovsk in Russia's Kamchatka peninsula along the coast of Avacha Bay, the USGS said as it revised the magnitude up from 8.0 earlier.
