How do I get earthquake hazard maps for locations outside of the U.S.?
We know of no current "zone" designations for sites outside of the United States. For locations outside the United States for which seismic design is required for military facilities, there exists a standard based on probabilistic spectral ordinates in the manner of the International Building Code and are declared to reflect the 2015 version of that code. These spectral ordinates can be found in the document "UFC 3-301-01, Unified Facilities Criteria (UFC), Structural Engineering." We know of a version representing a date as late as September 2016. You can obtain this document by Googling this string: UFC 3-301-01, September 2016. The spectral ordinates can be found in Table F-3.
What is the probability that an earthquake will occur in the Los Angeles Area? In the San Francisco Bay area?
What is the likelihood of a large earthquake at location X? Is it safe to go to X since they've been having a lot of earthquakes lately?
What is seismic hazard? What is a seismic hazard map? How are they made? How are they used? Why are there different maps, and which one should I use?
New seismic hazard and risk assessments can help at-risk communities prepare for future earthquake disasters
Despite the magnitude 8.2 earthquake that hit northern Chile in April 2014, the plate boundary in that region is still capable of hosting shocks of the same size or even greater in the near future, according to new research presented in Nature.
New Audiences, New Products for the National Seismic Hazard Maps
The USGS has updated the magnitude of the March 11, 2011, Tohoku earthquake in northern Honshu, Japan, to 9.0 from the previous estimate of 8.9. Independently, Japanese seismologists have also updated their estimate of the earthquake’s magnitude to 9.0.
Friday's magnitude-5.2 earthquake in southern Illinois is a reminder that earthquakes are a national hazard.
Example of results returned when searching the USGS Earthquake Catalog. The ANSS Comprehensive Earthquake Catalog (ComCat) contains earthquake source parameters (e.g. hypocenters, magnitudes, phase picks and amplitudes) and other products (e.g. moment tensor solutions, macroseismic information, tectonic summaries, maps) produced by contributing seismic...
The May 12, 2008, Great Sichuan Earthquake, also called the Wenchuan Earthquake, occurred at 14:28 local time, in Sichuan Province, China. The earthquake magnitudes were Mw = 7.9 (USGS), Ms = 8.0 (Chinese Earthquake Administration). The epicenter was 80 km west-northwest of Chengdu, the capital city of Sichuan province. Damage by earthquake-induced landslides was...
The 12 May 2008 earthquake was strong enough to pull apart this road in China.
A mosque is left standing amid the rubble in Banda Aceh. Several mosques survived and may have been saved by the open ground floor that is part of their design. The tsunami waves reached the middle of the second floor.
A masonry building in the downtown part of Concepcion, Chile partially collapsed as a result of the M 8.8 earthquake on Feb. 27, 2010. Most modern buildings in Concepcion were undamaged during the earthquake due to the city's adoption of adequate building standards. However, many masonry buildings such as this one were heavily damaged.
