A minor earthquake rocked parts of Southcentral Alaska early Tuesday morning.

According to the U.S. Geological Survey, the 4.0 magnitude quake occurred at 5:57 a.m. and was centered about 2.5 miles southeast of Willow.

Channel 2 Facebook users reported that the quake was felt as far north as Houston.

“Sweet shake in Willow,” wrote Adine Fullerton.

“In all my years of living here this one felt different,” wrote Kristina Libby. “It was a very hard rumble/vibration, not a shake back and forth. No aftershock either. It was so hard it woke me immediately!”
