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

statewide earthquake drill

• Over 800,000 registered participants
