Find recent or historic earthquakes, lists, information on selected significant earthquakes, earthquake resources by state, or find webservices.Latest earthquakes map and list for U.S. and worldwide. Name: The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. What does "earthquake hazard" mean?Interactive fault map and information on known or suspected active faults and folds in the United States.
Earthquake hazard map showing peak ground accelerations having a 2 percent probability of being exceeded in 50 years, for a firm rock site. Significant Earthquakes Archive. Locally, the hazard may be greater than shown, because site geology may amplify ground motions. The 2014 Fault Parameters are now available.
The USGS requests that the earthquake hazard community bring to our attention new earthquake source and ground motion data or models that could be included in the National Seismic Hazard Model (NSHM) updates. Search Earthquake Catalog *United States earthquake lists (except "Top...") also include some earthquakes outside the U.S. since the search area is a rectangle. Javascript must be enabled to view our earthquake maps. Probabilistic seismic hazard data and maps of Hawaii for peak ground acceleration (PGA) and 0.2, 0.3, and 1.0 second spectral acceleration at probability levels of 2 percent in 50 years (annual probability of 0.000404) and 10 percent in 50 years (annual probability of 0.0021), assuming firm rock soil conditions at 760 m/s, are available.
Uniform California Earthquake Forecasts (UCERFs) Time-dependent earthquake probability maps for California from the Working Group on California Earthquake Probabilities.
If the application does not load, try our legacy Latest Earthquakes application. Strong earthquakes in Hawaii have destroyed buildings, roads, bridges, and utilities. While the information presented on this website is believed to be correct, SEAOC /OSHPD and its sponsors and contributors assume no responsibility or liability for its accuracy. USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards. What do I need to know about earthquake hazards? Seismic hazard in Hawaii: High rate of large earthquakes and probabilistics ground-motion maps; 2001; Article; Journal; Bulletin of the Seismological Society of America; Klein, F. W.; Frankel, A. D.; Mueller, C. S.; Wesson, R. L.; Okubo, P. G. Tall buildings in … Also, generalized fault data used in the hazard maps.Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. The earthquake hazard in the State of Hawaii is among the highest in the United States. No data point selected. Gridded seismic hazard cruve data, gridded ground motion data, mapped gridded ground motion values, and the seismicity catalog are available for the 1998 Hawaii Seismic Hazard Model. Javascript must be enabled to view our earthquake maps.
USGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards. The design code developers first decide how USGS earthquake hazard information should be applied in design practice. To access USGS earthquake information without using javascript, use our Magnitude 2.5+ Earthquakes, Past Day ATOM Feed or our other earthquake feeds . This is a beta release of the new ATC Hazards by Location website. The map is based on the most recent USGS models for the conterminous U.S. (2018), Hawaii (1998), and Alaska (2007). Tap/click on "gear icon" for options and settings.Did You Feel It? The original dataset was assumed to be complete and accurate, but may contain inconsistencies when compared to more recent, actively maintained datasets.Below are publications associated with this project.The seismic hazard and earthquake occurrence rates in Hawaii are locally as high as that near the most hazardous faults elsewhere in the United States. 2018 Long-term National Seismic Hazard Map. Short-period ground motions effect short-period structures (e.g., one-to-two story buildings). When viewing the maps, it is important to remember that areas with high earthquake hazards do not necessarily face high seismic risks.
