The historical seismology record is a much longer, including written documentation such as news accounts and diaries, which vary widely by culture and region.

POPSTsunami devastates western Solomons The magnitude-8 quake struck shortly after 7:39 a.m. six miles beneath the sea floor, about 215 miles northwest of the Solomons capital, Honiara, the U.S. Geological Survey said. Within five minutes, waves 10-16 feet tall roared ashore and went up to half a mile inland, inundating buildings and sending thousands fleeing for higher ground, witnesses said. The Pacific region went on high alert for several hours after the quake struck between the islands of Bougainville and New Georgia, with Sydney's famous Bondi among beaches closed more than 1,250 miles away in Australia.
