Earthquake Probability Mapping

USGS Geohazards

This web site was designed to display earthquake probabilities that are computed from the source model of the 2008 USGS-National Seismic Hazard Mapping Project (NSHMP) update.


Suggested Educational use:
Have students pair up or divide into groups and give each group a major US City.
Have student look up Lat and Longitude using Atlases? or online ..(Geographical Skill)
Have students look at the tectonic setting of the cities and based on this have the students suggest the likely probability of a) an earthquake occuring b) possible size eg small, medium or large.c) impact
Then direct them to the USGS Earthquake Probability Mapping site and then, have them run through a series of scenarios e.g. Probaility of a Magnitude 5 occuring within the next 10 years, 20 years and so on, print off their plots in colour(nice for posters).
Summary
Have student collate information and decide which US city has the greatest risk of a large magnitude earthquake (7.0) occuring within the next 10 years.
Extension Activity
Students could look at possible earthquake management schemes that could be implemented, for example retro-fitting supporting columns, prepareness schemes, active monitoring etc
