Many geologists predict the near future will bring a major earthquake (M7.0) along the

Wasatch Fault, which cuts through Utah County. Many

school buildings in this county were built before

seismic building codes were introduced, which puts

schoolchildren at risk many hours each day.

PROBLEM STATEMENT

• April 17, 2013• Annual

statewide earthquake drill

• Over 800,000 registered participants

• Study conducted by USSC (Utah Seismic Safety Commission) found that 60% of statewide schools are potentially at risk
