A series of earthquakes shook the Aleutian Islands Monday morning, including a strong 6.4-magnitude quake near Adak.

According to the Alaska Earthquake Center, the big event struck at 9 a.m. about 80 miles west of the community, where about 350 people live.

“I would suspect that it was close enough to Adak that they should have felt it, but it’s probably not big enough to cause damage,” said seismologist Natalia Ruppert.

The city of Adak has downgraded a public notice calling for residents to boil their drinking water, after fixing a broken switch that compromised the water supply for nearly a month.

The community has been advised to boil water since 2007, because Adak’s aging treatment system relies on chlorine gas to disinfect water, rather than filtration.

The city of Adak is calling for all residents to boil their drinking water after their treatment system started malfunctioning. City Manager Layton Lockett says drinking the untreated water could make you sick.

“It’s like drinking out of a stream or a lake in that you might ingest some organisms that make your stomach upset,” Lockett said.
