ShakeMap is a product of the U.S. Geological Survey (USGS) to map the shaking of earthquakes. According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake ...
New Madrid seismic zone. The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold. [1][2] With a hazard thus estimated, risk can be assessed and included in such areas as building codes for standard buildings, designing larger buildings and ...
In an earthquake, damage to buildings and infrastructure is related more closely to ground motion, of which PGA is a measure, rather than the magnitude of the earthquake itself. For moderate earthquakes, PGA is a reasonably good determinant of damage; in severe earthquakes, damage is more often correlated with peak ground velocity .
Hazard map. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help prevent serious damage and deaths. [1]
Hazus is a geographic information system -based natural hazard analysis tool developed and freely distributed by the Federal Emergency Management Agency (FEMA). In 1997 FEMA released its first edition of a commercial off-the-shelf loss and risk assessment software package built on GIS technology. This product was termed HAZUS97.
The California Geological Survey releases tsunami hazard maps for Ventura, San Diego, Marin, Napa, Santa Cruz, Solano and Sonoma counties to help residents understand risks.
Foothills of Hurricane Cliffs, (city or landform locations) The Toroweap Fault of northwest Arizona and southwest Utah is part of a fault system of the west Grand Canyon region, Arizona, US; also the west perimeter regions of the Coconino and Colorado Plateaus. The Hurricane Fault originates at the Toroweap Fault, in the region of the Colorado ...
