An explosive eruption Friday at Shishaldin Volcano on the Aleutian Chain raised renewed unrest, resulting in a higher level of warning status by the Alaska Volcano Observatory.

About a year ago, the Alaska Department of Environmental Conservation tested Cold Bay’s water wells for PFAS, and the results came back well above the levels recommended for human consumption. Cold Bay closed the wells for drinking when the test results came back, and the Eastern Aleutian community has relied on state-provided bottled water ever since.

Shishaldin Volcano is spewing ash up to 27,000 feet in sky, leading to flight cancelations.

Shishaldin Volcano also erupted last month, sending ash over the Bering Sea.
