The 1963 Kuril Islands earthquake occurred at 05:17 UTC, on October 13.[2] The earthquake had a magnitude of 8.5 and was followed by a Mw 7.8 event seven days later.[3] Both earthquakes triggered tsunamis that were observed around the northern part of the Pacific Ocean.
No damage, deaths, or injuries were recorded for these two earthquakes or their associated tsunamis.
Characteristicsedit
Earthquakeedit
The earthquake was made up of three sub events, each of which is interpreted to represent the rupture of an asperity roughly 50 km in length along the subduction interface.[4]
Tsunamiedit
The tsunami triggered by the earthquake of October 13, caused a 4.5 m wave locally. The tsunami was also observed in Canada, Japan, Mexico, Hawaii, Alaska, California, and on many islands across the northern Pacific Ocean. The tsunami associated with the October 20 event was larger in the nearby area, with a maximum recorded run-up of 15 m at Urup, but was only observed in the western part of the northern Pacific.[1]
