Assessing Seismic Risk Of An Area
1. Locate and determine nature of faults in the area
2. Study history of earthquakes in the area
-Set up seismometersgives an idea of which faults are most active,
and the frequency and magnitude of quakes
critical to collect as long a seismic record as possible
How often do big earthquakes occur in the area? Which faults are
most active? What sort of energy is released by quakes?
EX: What zones are the most prone to earthquakes in Canada?
Looked at maps displaying seismic activity over 1 month, 1 year, 5
years, and 30 years and 3 major areas can be seen: Western Canada,
Eastern Canada, and Arctic. Low population in Arctic means less risk,
which leaves Western and Eastern Canada. We are looking at putting
a nuclear reactor in Kingston, so we zoom in on Eastern Canada. In
Kingston area, biggest quake is mag 2 even though there is a fair
amount of activity
-Determine the Recurrence Interval for “big” earthquakes in the area
How often do big quakes occur? (Big = greater than mag 7)
Recurrence intervals are averages, not set intervals of time!
