The "Parkfield earthquake prediction experiment" was the most heralded scientific earthquake prediction ever. [ 186 ] [ t ] It was based on an observation that the Parkfield segment of the San Andreas Fault [ u ] breaks regularly with a moderate earthquake of about M 6 every several decades: 1857, 1881, 1901, 1922, 1934, and 1966.

This earthquake alerted State and Federal officials that a facility was necessary to provide timely and effective tsunami warnings and earthquake information to the coastal areas of Alaska. Congress provided funds in 1965 to construct two new observatories and establish a tsunami warning system in Alaska.
The Advanced National Seismic System (ANSS) is a collaboration of the United States Geological Survey (USGS) and regional, state, and academic partners that collects and analyzes data on significant earthquakes to provide near real-time (generally within 10 to 30 minutes [1]) information to emergency responders and officials, the news media ...
A 7.2 magnitude earthquake triggered a brief tsunami advisory for southern Alaska late Saturday, but the advisory was canceled about an hour later, monitoring bodies reported. The earthquake was ...
Kagan & Knopoff (1987, p. 1563) define prediction (in part) "to be a formal rule where by the available space-time-seismic moment manifold of earthquake occurrence is significantly contracted ...."</ref> [2] Both forecasting and prediction of earthquakes are distinguished from earthquake warning systems, which, upon detection of an earthquake ...
The earthquake ruptured an area of about 120 mi × 60 mi (193 km × 97 km), equal to about 7,200 sq mi (19,000 km 2). The estimated maximum slip along this fault surface was about 3 to 4 m (9.8 to 13.1 ft). [30] The earthquake appears to have only partially ruptured the Shumagin segment of the subduction zone, at 75%.

The Salcha seismic zone is a fault line in the Interior region of Alaska, United States, generally located to the east of Fairbanks.The fault runs for 65 km (40 mi) from the northern edge of the Alaska Range across the Tanana Valley to the southern end of the Yukon–Tanana Uplands and is parallel to the Fairbanks and Minto Seismic Zones located further west.
