1997 Kamchatka earthquake
|Date||December 5, 1997|
|Origin time||11:26 UTC|
|Max. intensity||VII (Very strong) |
The 1997 Kamchatka earthquake, or 1997 Kronotsky earthquake, occurred on December 5 at 11:26 UTC near the east coast of the Kamchatka Peninsula. It is an Mw 7.7 (7.6-7.8) earthquake and was felt with intensity MM V in Petropavlovsk-Kamchatskiy. A 60 cm (23.6 in) tsunami was recorded in Kahului, 47 cm (18.5 in.) in Hilo, and 15 cm (6 in.) in Unalaska. The local tsunami generated by this earthquake affected a mostly unpopulated region. A post-tsunami survey found runup (height above normal sea level) on the Kronotsky Peninsula was no more than a few meters. However, a later geological survey north of the peninsula, as well as an interview with a park ranger, indicate that runup was up to 8 meters (26 ft) along the coast near the Little and Big Chazhma rivers and north to the Storozh River.
