THE TOHOKU TSUNAMI OF 11 MARCH 2011 AS RECORDED ON THE RUSSIAN FAR EAST
The source region of the catastrophic Tohoku tsunami of 11 March 2011 was near the Russian Far East, thus a warning was issued for threatened coasts of the Kuril Islands and Kamchatka. The tsunami was clearly recorded by a number of coastal tide gauges and by bottom pressure stations (including the...
