UNIMAK ISLAND, Alaska – Volcanic activity has significantly declined at Shishaldin Volcano, and any remaining ash emissions are likely low level, officials said.

The Alaska Volcano Observatory (AVO) said seismic tremor began declining from a peak at 2 p.m. Friday local time and is and is currently at low levels.

Weak steam and gas emissions are observed emanating from a new scoria cone that is now growing within the summit crater. A very minor deposit of dark ash is visible just downwind of the erupting vent on top of the snow. (USCG/Alaska Volcano Observatory)

The eruption produced a sustained ash plume ash during the period of high seismicity, which drifted to the northeast, the AVO said. Currently, meteorological clouds at 30,000 feet above sea level have obscured the volcano and any potential ash clouds.

"It is possible that low-level ash production could be continuing during this period of waning seismicity," the AVO added in their latest advisory.

The volcano's eruptive activity on Friday caused the AVO to elevate their color code and alert level to Red/Warning on their volcano alert scale. It was since decreased to an Orange/Watch level.
