Earthquakes and Tsunamis. According to long-term records (since about 1900), we can expect about 18 major earthquakes (7.0 - 7.9 on the Richter scale) and one great earthquake (8.0 or above) in any given year.

  1. Earthquakes and Tsunamis • According to long-term records (since about 1900), we can expect about 18 major earthquakes (7.0 - 7.9 on the Richter scale) and one great earthquake (8.0 or above) in any given year • The number of earthquakes and tsunamis resulting in fatalities has increased approximately in proportion to global populations • The growth of giant urban cities near regions of known seismic hazard is a new experiment for life on the Earth • Tsunamis are a threat to life and property for all coastal residents Sources: NEIC 2003; USGS 2004; UNEP 2005 (GEO 2004/2005)

  5. Tsunami - Lituya Bay Alaska On July 10, 1958, an earthquake triggered a landslide, which created a wave that wiped out trees 1,700 feet up a hillside on the opposite side of Lituya Bay, Alaska. Within minutes a wave that had traveled 2,500 miles from the Aleutian Islands in Alaska came crashing into Hilo. It killed one hundred fifty-nine people and caused millions of dollars in damages.
