A 6.9 magnitude earthquake has struck the Gulf of Mexico but did not generate a tsunami that would threaten Hawaii, officials said.

The quake was centered 83 miles northeast of Guerrero Negro, Baja California Sur, at a depth of 6.4 miles at 12:15 a.m. Thursday at the epicenter (9:15 p.m. Wednesday in Hawaii), according to the U.S. Geological Survey.

The Pacific Tsunami Warning Center in Ewa Beach issued a bulletin saying that the quake is not expected to generate a Pacific-wide tsunami.

It was the second major earthquake to strike Mexico in less than 12 hours.

The U.S. Geological Survey reported a 6.5 magnitude quake at 3:55 p.m. Wednesday local time (12:55 p.m. in Hawaii), centered in the sparsely populated mountainous area in Mexico’s Michoacan state, 238 miles west-southwest of Mexico City and about 209 miles west-northwest of Acapulco. Authorities in Michoacan state, where the tremor was centered, also had no immediate reports of damage.

The earlier quake also did not generate a destructive tsunami.
