Preliminary magnitude-4.5 quake shakes northwestern Oklahoma May 25, 2021 FacebookTwitterEmail SHATTUCK, Okla. (AP) — A strong earthquake measured at a preliminary magnitude of 4.5 rattled a small northwestern Oklahoma town Tuesday but apparently caused no injuries or significant damage. The U.S. Geological Survey reported the quake struck about 1:25 p.m. near Shattuck, a town of nearly 1,500 population about 145 miles (233 kilometers) northwest of Oklahoma City and near the border with the Texas Panhandle. People fled businesses along the town's main street, said Shattuck City Manager Sam Hamilton, but no injuries or damage have been reported. “It rattled the buildings. I thought something blew up ... it was like an explosion,” Hamilton said, calling it the first earthquake he had ever experienced.
