RENO, Texas -- Dwayne Harris, 83, has a full calendar. Mainly because he meticulously logs every earthquake he feels at his home in the town of Reno in Parker County.

Had so many I can't remember all of them, he said.

There are 24 entries on his calendar since Nov. 5. He records the time, magnitude, and notes about what happened inside the house.

All of a sudden, the windows shook and the monitor rattled, Harris reads from one entry.

His wife Jean said knick-knacks fell out of a shadow box and broke. They ve noticed a widening crack creeping across their bedroom wall.

Then, there was the quake on a recent Sunday morning.

When we were in church, the pew shook back and forth, Jean Harris said.

Last week, the US Geological Survey (USGS) determined that many tremors are clustered near the Harris' home. It's between the towns of Reno and Briar.

USGS researchers believe waste water injection wells could be triggering small quakes in Texas and Oklahoma.

They've moved sensors to the area near the Harris' home. There s an injection well about a mile-and-a-half away.

There are thousands of injection wells across Texas. Geologists say the vast majority of them cause no problems with earthquakes. The Texas Railroad Commission, which regulates oil and gas exploration, will discuss the quakes with residents at 5 p.m. Thursday at the Azle High School auditorium.

We've been told they won't get too much stronger, Dwayne Harris said, but that's something no one knows.

He s waiting to hear about his application for earthquake insurance. And hoping he won't be filling his 2014 calendar with entries about earthquakes.
