M 6.9 Earthquake Kuril Islands

last updated 17 February 2020, 8:32 UTC

On 13 February 2020 a strong earthquake occurred at the Kuril Islands. The tremor with an estimated moment magnitude (Mw) 6.9 occurred at 11:33 UTC.

A quake watch was issued on the 10th because of a convergence of critical planetary and lunar geometry late on the 10th and early 11th. Increased seismic activity was anticipated to occur from the 11th to the 13th with an estimated peak magnitude of 6.5 to 7.0. As no larger seismic activity occurred on the 11th and 12th, an additional warning for a "higher 6 to 7 magnitude earthquake" was issued on the 13th - about 4 minutes before the earthquake occurred.
