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. 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[clarification needed] 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 m along the coast near the Little and Big Chazhma rivers and north to the Storozh River.
Deformation during and after this earthquake was measured by GPS  There were significant foreshocks, and also an apparently independent rupture along the southern border of the primary rupture
