Comment: Coles Hill sits on the Chatham Fault, look at the following comment, they are mining in TX too: "Earthquakes can be caused by drilling for minerals"! Keep the uranium mining ban!

Arthur Troell, 76, had just sat down to his kitchen table for his morning routine — writing a few lines of poetry.
It was about 7:20 a.m. this morning when his house began to quake.
"All of a sudden … the refrigerator made this tremendous noise. I thought it was going to fall on me," the retired geology professor said in a telephone interview from his home in Pleasanton.
By now, most people in San Antonio know that South Texas was rocked by a record-breaking earthquake that registered at a magnitude 4.8, according to the U.S. Geological Survey website.
After a 5.8 earthquake in Virginia that shook the eastern seaboard from the Carolinas to New England Aug. 23, local television news reporters called on him to explain the phenomenon.
Troell showed a reporter the fault line on his property. Television viewers could see the huge crevices in the earth along the fault line.
Earthquakes can be caused by drilling for minerals. Over time, rocks can eventually slip or fail and that can trigger an earthquake, Troell said.
He went on to explain that most of the earthquakes in this region are attributed to minerals being removed from underground and rocks slipping over a long period of time.
