OKLAHOMA CITY – As many Oklahomans know, the number of earthquakes in the state has jumped significantly since 2009.

Since October, the rate of earthquakes has jumped by about 50 percent.

In a release by the U.S. Geological Survey and the Oklahoma Geological Survey, experts say the chance of a damaging earthquake over 5.5 magnitude is growing at a disturbing pace.

Experts say residents in central Oklahoma should be aware of the hazard and be prepared.

Officials also say building owners should pay close attention to their homes, which are vulnerable to considerable damage during a quake.

At this time, they don’t know where a massive earthquake will strike or when.

A new analysis found that 145 earthquakes of 3.0 magnitude or greater occurred in Oklahoma from January 2014 through May 2.

The previous record was set in 2013 with 109 earthquakes.

From 1978 to 2008, the average rate of earthquakes was just two 3.0 magnitude quakes  a year.

The analysis suggests that a factor playing a role in the increased number of earthquakes is wastewater injected into the ground.

The USGS published a report, saying the 5.0 earthquake that hit Prague in 2011 was human-induced.

The OGS says it has increased the number of monitoring stations across the state.
