ANCHORAGE, Alaska — A light earthquake has occurred near where Saturday’s major quake struck in Southeast Alaska.
The Alaska Earthquake Information Center said the quake occurred Tuesday morning at 5:46 a.m. and had a preliminary magnitude of 4.0. It was centered 98 miles west-northwest of Craig, which is very close to where Saturday’s powerful 7.5 magnitude earthquake struck. That earthquake prompted a tsunami warning for hundreds of miles of Alaskan and Canadian coastline.
The alert was canceled when no damaging waves were generated.
Tuesday morning’s earthquake likely was an aftershock. It is one of several that have occurred since Saturday.
Officials in Juneau said the Saturday earthquake was possibly to blame for damage to a sewer line and two water valves.
KINY said mainline sewer pipe at Mendenhall Loop and Back Loop Road collapsed and backed up.
Public works director Kirk Duncan said a Mendenhall Valley water valve blew up, and is probably earthquake related. He said a Douglas Island water valve also was reportedly damaged.
Fire Chief Rich Etheridge said existing cracks at a downtown station opened wider.
Also, an exterior wall at the fire training center developed a large crack behind the fuel tank.
