No one can predict when, where, and how big the next earthquake might be, but earthquake-prone places like California and Japan have installed systems that can warn of ground-shaking a few seconds in advance.  These systems, known as “earthquake early warning systems,” exploit the different waves produced by earthquakes.

Rocky Mountain Power crews are working to restore power to residents along the Wasatch Front following a Wednesday morning earthquake.  At the time of the 5.7 magnitude earthquake, approximately 73,000 customers were without power.  Logan City public works officials say the power outage did not affect residents there.

Around 700 earthquakes shake Utah each year, although only about a dozen are big enough to be felt. Most are natural, but humans can cause earthquakes, too. Recently, in Texas, Oklahoma, and Arkansas, earthquake frequencies have increased around deep-well injection sites, where millions of gallons hydraulic fracturing fluid is pumped deep into the Earth’s crust.
