CAMARILLO, calif. -

Hundreds of emergency workers and volunteers made it look very real during a huge drill on Wednesday.

The scenario in this case was a 7.0-magnitude earthquake.  The location is the Cal State Channel Islands campus in Camarillo.

  When first responders arrive, they have to evaluate dozens of people who were hurt and to get them medical attention.  Drills like this help prepare first responders for a real disaster.

"What we do is we evaluate our own practices after this.  We go back and determine how our communications went, how seamless the operation was.  You have to imagine in a real emergency it is quite chaotic.  One thing we can't simulate here is an actual collapse of a structure.  We can't simulate aftershocks, and those are all things we need to take into consideration should the real thing occur," said Robert Welsbie with the Ventura County Fire Department.
