At least nine earthquakes were reported Tuesday in central Oklahoma, some large enough to jolt people in the area, but no damage was reported.

The largest of the quakes was reported at 1:56 a.m. near Luther and woke people in the region. The 4.3 magnitude quake was followed by a 4.2 temblor at 5:16 a.m. in the same area. Other smaller earthquakes occurred throughout the day.

Quakes with a magnitude of 3 are among the smallest that are generally felt, while a magnitude 4 quake can do some damage.

Austin Holland, a seismologist with the Oklahoma Geological Survey, said Tuesday's string of quakes was different from other earthquakes that have struck the area in recent years. The largest earthquake in state history was a 5.7 magnitude quake in November 2011 near Prague.

“These certainly are very different earthquakes than what we've seen in the past,” Holland said. “These were very shallow. They are fairly rare. We haven't seen a series like this that has been so shallow with these size earthquakes.”

The quakes that hit the state Tuesday were centered four to five kilometers below ground. Most quakes are dozens of kilometers or more below ground.

I would assume this is some sort of temporary phase. But how long that temporary is, in geologic terms, that could be hundreds or thousands of years. Who knows what kind of time frame that might be.”
