LOL, the 4.2 in magnitude earthquake only semi-woke me up this morning. While groggily sensing the distant rumbling noise and light shaking sensation, I told myself just go back to sleep, and I'll check on the Internet when I wake up to see if it was a real quake, rather than dreaming it.

Experts seem concerned that these stronger quakes are a sign of more to come. I hope not. When nearby earthquakes go over 5.0 in magnitude, they are really scary for sure then and not a joking matter. The hot spots for earthquakes quite near my town, Stillwater, remain settled down for now. Just the loud noise from a 2.5 magnitude earthquake centered in or near the Stillwater city limits can be rudely frightening.

Scientists are working to determine what caused six earthquakes near Stroud Friday morning. The cluster started with a 4.2 magnitude earthquake, and five more quickly followed nearby.

While many of Oklahoma’s earthquakes have been linked to wastewater disposal into the earth's crust, researchers still have yet to discover how long it takes the faults to react to water pressure, so this cluster could point to additional events in the future.

Now, a feverish accumulation of data is underway at the Oklahoma Corporation Commission and Oklahoma Geological Survey to map and analyze a nearly straight line of earthquakes from northwest to southeast.

“We have no mapped faults around that event,” notes OCC spokesman Matt Skinner.

OGS seismologists say the cluster reveals a previously unknown vertical fault halfway between Stroud and Cushing. The first quake rumbled about five miles under the earth's surface, with the subsequent quakes growing weaker and shallower along the line.
