An earthquake with a preliminary magnitude of 5.2 shook Southcentral Alaska just after 11 a.m. today, according to the West Coast and Alaska Tsunami Warning Center in Palmer. The quake hit at 11:06 a.m. Its epicenter was 9 miles east-northeast of Nikiski and it was 30 miles deep, said Cindi Preller, tsunami program manager for Alaska.
"It woke us all up," she said. "Who needs coffee?"
The center said no tsunami would be generated from that quake.
There were no immediate reports of damage.
"I'm about to call Nikiski and make sure they're OK," she said.
Though the quake was 50 miles southwest of Anchorage, most of the calls coming into the center were from the Matanuska Valley, Preller said.
At the warning center, it felt like "a nice, long shaking," Preller said. In East Anchorage, people felt a hard jolt.
"Which means you felt the P wave and we felt the S wave," she said, contrasting the initial compression wave that struck Anchorage with the vertical, rolling wave felt in the Valley.
