Scientists have downgraded the alert level at Makushin Volcano after a sustained pause in unrest. 

John Power, a geophysicist with the Alaska Volcano Observatory, said the seismicity has been steadily declining for months, following an earthquake sequence near the volcano that began in mid-June.

In the wake of recent tsunami warnings across Coastal Alaska, and especially here in Unalaska, where over half of the city's tsunami sirens aren't functioning, emergency preparedness has been on the minds of many Alaskans.

A magnitude-7.8 Aleutian earthquake late Tuesday night prompted tsunami warnings in communities across coastal Alaska, from Homer to Unalaska.  

Sand Point is a fishing community of about a thousand people, located about 550 miles southwest of Anchorage in the eastern portion of the Aleutian Chain. Earthquake damage closed both its city docks, which it uses to land the M/V Tustumena ferry and freight boats, and damaged the road to the harbor.

The Department of Public Safety says Unalaska is in the clear after a tsunami warning Tuesday night caused Unalaskans to evacuate to higher ground. 

Communities throughout the Alaska Peninsula and Eastern Aleutians received warnings after a magnitude-7.8 earthquake hit approximately 75 miles south of Chignik.
