LAS VEGAS -- Earthquakes may not be top of mind for most Clark County residents, but firefighters say the danger is very real.
There are numerous fault lines in the county. Some are under major intersections, such as, Tropicana Avenue and Decatur Boulevard, Charleston and Las Vegas boulevards, and Flamingo Road and I-15.
There is a 40 to 50 percent chance of a 5.0 magnitude earthquake in the Las Vegas valley in the next 50 years, according to Nevada Bureau of Mines and Geology.
Clark County firefighters visited some local schools Tuesday to make sure kids know what to do if an earthquake strikes.
Gavin Schurr, 10, knows what causes earthquakes.
"'There's like platonic plates underground and they kind of hit each other and it goes off," he said.
What Schurr may not know is that Nevada is the third most seismic area in the country and that's why firefighters say it's so important to be prepared.
"Ok guys, stop, drop and take cover," the teacher tells the students.
"You just go under your desk, cover your neck and head," Schurr said.
"The lessons we're teaching the kids here is going to have ramifications all across the world," said Capt. Scott Straily, Clark County Fire Department.

Between southern Nevada's extensive network of fault lines and bigger earthquakes in neighboring California, firefighters say it is only a matter of time before an earthquake shakes the valley.
"An earthquake can strike anytime, anywhere," Straily said.
While the drill only lasted a minute or two, it could be a safety lesson that will last a lifetime for many of the students.
The most recent earthquake in Nevada happened on Monday in Alamo. It was only a 2.6 magnitude.
