Webcams on Thursday clearly showed episodic low-level ash emissions from Pavlof Volcano, prompting the observatory to raise the volcanos threat level from yellow, or exhibiting signs of unrest, to orange, indicating an eruption is underway with minor volcanic ash emissions. Increases in seismic activity have been detected previously at other similar volcanoes, with no subsequent eruptions. The volcano is about 4.4 mi (7 km) in diameter and currently has an active vent on the east side close to the summit. Research carried out by the Alaska Volcano Observatory in collaboration with the Alaska Satellite Facility used mathematical modeling based on satellite imagery to determine that this recent increase in seismic activity had been caused by the upward thrust of moving magma deep under the earth's surface.

Its also based on how close a volcano is to homes, businesses and structures. Previous eruptions of Pavlof indicate that the level of unrest can change quickly and the progression to more significant eruptive activity can occur with little or no warning. Increases in seismic activity have been detected previously at other similar volcanoes, with no subsequent eruptions. The most recent significant period of eruption began in February 2001 and produced 3 explosive events that generated ash clouds as high as 39,000 ft (11.8 km) above sea level.

Takawangha's summit is mostly ice-covered, except for four young craters that have erupted ash and lava flows in the last few thousand years. In volcano preparedness, knowing where the next socially disruptive eruption may take place is half the battle. The activity from the Hunga Tonga-Hunga Ha'apai volcano continued into Saturday morning with another, less powerful 10- to 15-minute-long eruption, according to the Tonga Geological Service. "Detecting magma movement at depth is usually a reminder that a volcano is active, or potentially active, but it isn't necessarily a sign that a volcano will erupt," Pyle said. During this time, they may erupt when magma rises up from deep inside the Earth and reaches the surface. Eruptive activity is generally characterized by sporadic Strombolian lava fountaining continuing for a several-month period. . It might not erupt. We expect additional shallow seismicity and other signs of unrest, such as gas emissions, elevated surface temperatures, and surface deformation to precede any future eruption, if one were to occur.
