The worst damage of a tremor is at the epicenter, but even a large magnitude quake might cause little actual damage. Some parked vehicles may rock slightly. For lack of a better descriptor, it possible effects of a Big One become real. This means that an earthquake may have different intensities from place to place, but it will only have one magnitude. Felt quite noticeably by persons indoors, especially on upper floors of buildings. The Richter Scale is not used to express damage. It's not that you can't find earthquake threat information for other parts of the country, it's finding actual scenario "what ifs" and loss estimations that are based in scientific data. Humans cannot eliminate the hazards but can take steps to reduce their impacts. University of California during the earthquake. These experts use knowledge and experience from what is known about earthquake risks and hazards, often through historical and similar event references, in an effort to best calculate the potential and expected damage an earthquake or a projected magnitude will cause in an area.

Assigning of MM intensity values therefore involves use of the original criteria of Wood and Neumann (1931) with amendments and modifications that have been developed in the decades since 1931. Fall of cornices from towers and high buildings. The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. Not felt except by a very few under especially favorable conditions. [8], In their 1993 compendium of historical seismicity in the United States,[12] Carl Stover and Jerry Coffman ignored Richter's revision, and assigned intensities according to their slightly modified interpretation of Wood and Neumann's 1931 scale,[a] effectively creating a new, but largely undocumented version of the scale. Frightened all - general alarm, all ran outdoors. There are 72,126 children who spend at least some of their schooling in those buildings. The scale looks at areas surrounding the epicenter and a A pull-apart basin can be created in a strike-slip fault zone. within type by subtype, then by grade, etc. This gives numerous and extensive.
