how much damage did the alaska earthquake cause 2018
2018 Gulf of Alaska earthquake According to the United States Geological Survey, the earthquake occurred 175 miles (282 km) southeast of Kodiak, Alaska at 12:31 AM local time (AKST).[2] Witnesses to the earthquake itself reported that it was very long in duration, feeling like a "slow roller," but it was not a violent earthquake despite its magnitude. This was corroborated by witnesses in Anchorage.[8][6] There was no immediate damage reported.[6] The earthquake woke people in Anchorage, 350 miles (560 km) from the epicenter, and was felt as far as Fairbanks to the northeast and British Columbia to the southeast.[4][5] The earthquake's S-waves arrived in Anchorage within one minute, and reached Fairbanks within three minutes.[9]
San Andreas Fault The U.S. Geological Survey most recent forecast, known as UCERF3 (Uniform California Earthquake Rupture Forecast 3), released in November 2013, estimated that an earthquake of magnitude 6.7 M or greater (i.e. equal to or greater than the 1994 Northridge earthquake) occurs about once every 6.7 years statewide. The same report also estimated there is a 7% probability that an earthquake of magnitude 8.0 or greater will occur in the next 30 years somewhere along the San Andreas Fault.[15] A different USGS study in 2008 tried to assess the physical, social and economic consequences of a major earthquake in southern California. That study predicted that a magnitude 7.8 earthquake along the southern San Andreas Fault could cause about 1,800 deaths and $213 billion in damage.[16]
