Short summary

The 5 Dec 1997 magnitude 7.8 Kronotsky earthquake and tsunami occurred on a dark night in an unpopulated area. A limited (Dec 97) post-tsunami survey found relatively small run-up, which influenced some earthquake analyses. Years later, to our surprise, we discovered an extensive tsunami deposit up to 9 m above sea level on an unexplored coastal sector. Our tsunami runup data require reevaluation of earthquake rupture location and characteristics, and of the northern Kamchatka subduction zone.
