Local Seismologists Monitor Aftershocks Following 4.2 Earthquake

Posted: Updated:

Monday's 4.2 magnitude quake in Spanish Springs only lasted a few seconds, but a day later, seismologists are still talking about its impact.

Ken Smith, the seismic network manager for the Nevada Seismological Lab at the University of Nevada said they aren't surprised by the quake.

Smith said in the past week or so, they have seen a swarm of smaller quakes leading up to this one. Last year, there was about 100 in that same area.

Seismologists are now busy recording aftershocks.

"They been going on continuously, pretty small events," said Smith. "We haven't had anything large enough to be felt, maybe one of the aftershocks. It hasn't been that big. It wouldn't be surprising to see an aftershock of a magnitude 3.0 or something like that in the near future."

Smith said we get, on average, at least one magnitude 4.0 to 5.0 earthquake in our area every year.

This year, he said we've had 2,500 quakes, but most are too small to feel.

The one we felt Monday is the largest.

Here's the difference between this one and the ones we saw in 2008 near Somersett.

This quake was much deeper, about eight and half miles below the surface. The big quake in '08 was much more shallow, so it felt a lot stronger relative to this one.

Now the recent quake activity, according to Smith, does not necessarily mean a bigger one is imminent.

"There's always a possibility this is a precursor for another larger event, but we don't know that. We can't forecast or predict it, so we want to stay on top of it as much as we can."

Here's a few simple safety tips for you if another quake does indeed take place:

  • If you start to feel shaking, duck, cover and hold
  • Always have an emergency plan in place, just in case something ever happens
  • Stock up on supplies, always have extra food and water at your home
