3.4 magnitude earthquake shakes part of northern Oklahoma

January 7, 2019

MEDFORD, Okla. (AP) — The U.S. Geological Survey says a 3.4 magnitude earthquake has shaken parts of northern Oklahoma.

Geologists say the temblor was recorded at 10:43 a.m. Monday less than 1 mile (1 kilometer) northeast of Medford near the Kansas border and about 93 miles (150 kilometers) north of Oklahoma City. The quake was recorded at a depth of 3 miles (5 kilometers).

No damage was immediately reported. Geologists say damage is unlikely in temblors below magnitude 4.0.

Thousands of earthquakes have been recorded in Oklahoma in recent years, with many linked to the underground injection of wastewater from oil and l gas production.

Geologists say about 200 quakes of magnitude 3.0 or stronger were recorded in Oklahoma last year. That number has declined for the third straight year after state regulators began directing oil and gas producers to close some wells and reduce injection volumes in others.
