Probabilistic seismic hazard map. The earliest known earthquake in the U.S. state of California was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also ...

The color-coded map shows a range of earthquake probability across the U.S. Well known high-risk areas, such as California and Alaska, are coded in dark red, denoting the highest risk.
The 1933 Sumatra earthquake or Liwa earthquake affected southern Sumatra, Indonesia, on 25 June at 04:54 WIB. The earthquake had an estimated surface-wave magnitude (M s ) of 7.5–7.7 and occurred at a shallow depth of 20 km (12 mi). It was caused by slip along a 130 km (81 mi) section of the seismically active Great Sumatran fault.
This quake, together with the Great Alaskan earthquake (1964) and the Great Chilean earthquake (1960), account for almost half of the total moment. [35] [36] Since 1900, the only earthquakes recorded with a greater magnitude were the 1960 Chile earthquake (magnitude 9.5) and the 1964 Alaska earthquake in Prince William Sound (magnitude 9.2
The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak [1] [2] where the Honey Lake Fault Zone, the Warm Springs Valley Fault, and the Pyramid Lake Fault Zone [3] meet the transverse tectonic zone forming the southern boundary of the Modoc Plateau and Columbia Plateau provinces.
A full fault rupture, estimated to be around a 7.5 magnitude, could kill between 3,000 and 18,000 people, according to US Geological Survey and Southern California Earthquake Center.
