One of the strongest earthquakes ever recorded struck Russia's sparsely populated Far East on Wednesday, causing tsunamis up to four metres (12 feet) high across the Pacific and sparking evacuations from Hawaii to Japan.
The magnitude 8.8 quake struck off Petropavlovsk on Russia's remote Kamchatka peninsula, and was the largest since 2004 when one of magnitude 9.1 near Indonesia's Sumatra island triggered an Indian Ocean tsunami, killing around 220,000 people in 11 nations.
