Six new quakes in the Yellowstone National Park area have rattled Idaho and Montana.
The first quake struck at 1:10 a.m.
(1:10 GMT) at the edge of the park at an elevation of 207 feet (24.5 meters), according to a U.S. Geological Survey report.
The quake occurred along a fault line about 100 miles (160 kilometers) north-northwest of the town of Crested Butte.
It’s about one-third of a mile (1.3 kilometers) long and centered about 60 miles (97 kilometers) northeast of the city of Fairbanks.
The second quake struck about 30 minutes later, about 40 miles (65 kilometers) northwest of the original quake’s epicenter, about 50 miles (80 kilometers) east of Fairbank.
The quake occurred in the area of a fault known as the Teton Fault, and its magnitude was about 5.3.
The third quake was about a mile and a half (1 kilometer) southeast of the first and was centered about 45 miles (72 kilometers) southeast on the Yellowstone River.
The magnitude was 4.5.
