Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions. Residents and visitors should minimize exposure to Pele's hair and other glassy volcanic fragments, which can cause skin and eye irritation.

Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions. Residents and visitors should minimize exposure to Pele's hair and other glassy volcanic fragments, which can cause skin and eye irritation.

The caldera-forming eruption occurred around 3,500 years ago. Post-caldera eruptions have produced lava domes, tuff cones, and larger spatter and scoria cone structures, including Half-Cone and Vent Mountain, all within the caldera. The most recent eruption occurred in 1931 and created a new vent and lava flows on the western caldera floor while spreading ash over much of southwestern Alaska. Aniakchak volcano is 16 miles (26 km) southeast of the nearest community, Port Heiden, and 416 miles (670 km) southwest of Anchorage, Alaska.

The dual north vents stopped erupting much earlier at approximately 11:50 a.m. Lava fountains reached heights of up to 1,000-1,200 ft (300-370 m) during episode 38. Fountains were down to about 400 feet (120 meters) high just before the abrupt end of the eruption. Lava fountaining lasted for 12.1 hours and produced an estimated 16 million cubic yards (12 million cubic meters) of lava. The combined average eruption rate was over 250 cubic yards per second (190 cubic meters per second) from the lava fountains.\u003C\/p\u003E\u003Cp class=\u0022hans-paragraph\u0022\u003ESustained lava fountains began erupting from two vents located within the north cone at 8:45 a.m. HST on December 6 after just over 5 hours of precursory lava overflows. The south vent then began fountaining at 8:49 a.m. By 9:15 a.m. a rare triple fountain event was underway with the two north vents and the south vent all erupting together at heights of about 500 feet (150 meters). By 9:40 a.m. the south vent fountain grew to about twice as high as the north vent fountains. The highest peak or instantaneous effusion rate of 1,300 cubic yards per second (1,000 cubic meters per second) occurred just before 10 a.m. when the south vent exploded. The enlarged south vent produced an inclined fountain over 1,000 feet (300 meters) tall that sprayed the south wall of Halema\u02bbuma\u02bbu crater. Hot pumice and molten spatter from this fountain destroyed the HVO \u0022V3\u0022 streaming camera site.\u003C\/p\u003E\u003Cp class=\u0022hans-paragraph\u0022\u003ELava flows from this episode's fountains covered 50-60% of the floor of Halema\u02bbuma\u02bbu crater.

Earlier today the gas plume reached over 20,000 feet (6000 meters) above sea level. Tephra including Pele's hair and fine ash carried in lower levels of the plume fell in the town of Pahala and other communities southwest of the vents. Satellite imagery showed the upper regions of the gas and ash cloud moved due east of the summit across lower Puna and well out to sea before turning south. Reticulite pieces up to the size of a baseball fell along Chain of Craters Road east of K\u012blauea\u02bbs summit transported by the high eastern plume. The extremely high effusion rates early in the eruption provided the gas and heat that drove this enormous plume.\u003C\/p\u003E\u003Cp class=\u0022hans-paragraph\u0022\u003EThe U\u0113kahuna tiltmeter (UWD) recorded about 33.1 microradians of deflationary tilt during this episode.

Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions. Residents and visitors should minimize exposure to Pele's hair and other glassy volcanic fragments, which can cause skin and eye irritation.

Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions. Residents and visitors should minimize exposure to Pele's hair and other glassy volcanic fragments, which can cause skin and eye irritation.

Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions.

Pele's hair is strands of volcanic glass often produced by lava fountaining activity and can be carried well over 10 miles (15 kilometers) from the vent. Other hot glassy volcanic fragments including Pele\u02bbs hair, volcanic ash, pumice, scoria, and reticulite can fall on the ground within 1-2 miles (1-3 kilometers) of the eruptive vent(s) with the highest concentrations downwind of the vent(s). Pumice and other volcanic fragments have fallen on Highway 11 west of Hawai\u02bbi Volcanoes National Park depending on wind and eruption conditions.  Strong winds may waft light particles, including Pele's hair, to greater distances downwind. Once they are on the ground, Pele's hair can sometimes cluster and tangle together, giving it the appearance of a tumbleweed. The extent of Pele's hair deposition is dependent on lava fountaining activity and current wind conditions. Residents and visitors should minimize exposure to Pele's hair and other glassy volcanic fragments, which can cause skin and eye irritation.
