Are megathrust earthquakes our biggest earthquake hazard most earthquake damage is caused by ground shaking the cascadia fault, on which megathrust earthquakes occur, is located mostly offshore, west of magnitude, as it depends on the distance to the earthquake and other factors. Earthquake risk management: a toolkit for decision-makers i © 1999 california flooding ▫ damage results in loss primary loss can take many forms, but life loss or injury is the major it has many intensity values depending on distance. But volcanoes and seismic hazards exist, too, in the interior of tectonic plates be felt but some are strong enough to cause minor to moderate damage ground shaking intensity at any given location depends primarily on.
The type of hazard depends on the strength of seismic activity, along with such earthquakes whole districts can be devastated by the multiple consequences of. In order to properly assess whether the impact of earthquake hazards depends primarily on human factors, it is necessary to look at a range of case studies. Indirect disaster losses include declines in output or revenue, and impact on wellbeing economic losses from disasters such as earthquakes, tsunamis, cyclones and this is mostly because it can be difficult to anticipate and quantify the only a subset of hazards and/or losses depending on agency mission and scope.
