The 1997 Kamchatka earthquake, or 1997 Kronotsky earthquake, occurred on December 5, 1997 at 11:26 UTC near the east coast of the Kamchatka Peninsula.[1] It is an Mw 7.7 (7.6-7.8) earthquake and was felt with intensity MM V in Petropavlovsk-Kamchatskiy. A 60 cm tsunami was recorded in Kahului, 47 cm in Hilo, and 15 cm in Unalaska. The local tsunami generated by this earthquake affected a mostly unpopulated region. A post-tsunami survey found runup on the Kronotsky Peninsula was no more than a few meters.[2] 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 m along the coast near the Little and Big Chazhma rivers and north to the Storozh River. [3]
Deformation during and after this earthquake was measured by GPS [4] There were signfiicant foreshocks, and also an apparently independent rupture along the southern border of the primary rupture [5]
