Manam Volcano Puffs Out a Small Plume
Manam Volcano released a small plume on June 16, 2010, which was captured by ALI on NASA’s EO-1 satellite. Source: NASA E/O.
The 1,807-m Manam, one of Papua New Guinea most active volcanoes, last erupted in 2009, is a basaltic-andesitic stratovolcano forming a 10-km wide island, located about 13km off the coast of mainland PNG.
“Frequent historical eruptions, typically of mild-to-moderate scale, have been recorded at Manam since 1616. Occasional larger eruptions have produced pyroclastic flows and lava flows that reached flat-lying coastal areas and entered the sea, sometimes impacting populated areas.” —GVP.

The Soufriere Hills volcano in Montserrat ejects a large plume of ash up to 12km into the air
Passengers on a 737 jet flying over the Caribbean had a close-up look at a massive volcanic eruption which ejected a plume of ash and smoke higher than the flight altitude. Early reports indicate that a partial collapse of the volcano’s lava dome may have caused the mushroom cloud. (Image: Mary Jo Penkala/Solent). Image may be subject to copyright.
A massive eruption of Montserrat’s Soufrière Hills Volcano triggered by a collapse of Soufrière Hills’ summit lava dome covered large portions of the island in debris on February 11, 2010. Pyroclastic flows raced down the northern flank of the volcano, leveling trees and destroying buildings in the village of Harris, already abandoned after Soufrière Hills activity in 1995. The Montserrat Volcano Observatory reported that some flows, about 15 meters (49 feet) thick, reached the sea at Trant’s Bay, extending the island’s coastline up to 650 meters (2,100 feet). These false-color satellite images show the southern half of Montserrat before and after the dome collapse. The top image was taken on February 21, 2010, 10 days after the event. The bottom image shows the same area on March 17, 2007. Red areas are vegetated, clouds are white, blue/black areas are ocean water, and gray areas are covered by flow deposits. Fresh deposits are lighter than older deposits. On February 21, the drainages leading down from Soufrière Hills, including the White River Valley, the Tar River Valley, and the Belham River Valley, were filled with fresh debris. Pyroclastic flows reached the sea through Aymers Ghaut on January 18, 2010, and flows entered the sea near Plymouth on February 5, 2010, Montserrat Volcano Observatory said.

Uncertain Future for Montserrat Island
Montserrat island could become completely uninhabitable by 2013 or earlier
Based on the pattern of volcanic activity at Soufriere Hills volcano since 1995, evidence of increased volcanism globally and a number of other factors, the FEWW EarthModel forecasts the probability of Montserrat island becoming completely uninhabitable as follows:
Probability of Montserrat Becoming Uninhabitable in the Near Future
- 2009 ≥ 50%
- 2010 ≥ 56%
- 2011 ≥ 60%
- 2012 ≥ 70%
- 2013 ≥ 80%
Montserrat Island Details:
- Capital:
- Plymouth (destroyed in 1997- see photo below)
- Brades (de facto)
- Location: Montserrat Island
- Coordinates: (16.72 N, 62.18 W)
- Height: 915 meters (3,010 feet)
- Official languages: English
- Ethnic groups: West African, Mulatto, British, Irish
- Government: British Overseas Territory
- Area: 102 km² (39 sq mi )
View E across ash-covered Plymouth, the former capital city and major port of Montserrat, toward Soufriere Hills volcano. Before the volcano became active in July 1995, about 5,000 people lived in Plymouth, located 4 km west of English’s Crater. During the first two years of the eruption, ash and noxious gas from explosions and pyroclastic flows frequently settled on Plymouth. On August 3, about 3 weeks after this image was taken, the first significant pyroclastic flow swept through the evacuated town. The flow triggered many fires and caused extensive damage to buildings and community facilities by direct impact and burial. Date: 12 July 1997. Credit: R.P. Hoblitt/ USGS.

Current Aviation Color Code: ORANGE
Aviation Color Code: ORANGE
Activity Summary for past 24 hours:
Growth and partial collapses of the Halema`uma`u Overlook vent cavity floor continued periodically obscuring and revealing the circulating lava pond surface. Sulfur dioxide emission rates from the Halema`uma`u and east rift zone vents remain elevated. Lava flows are active on the coastal plain. Lava is also flowing through tubes to the coast and entering the ocean at two locations west of Kalapana.
Past 24 hours at Kilauea summit:
The Overlook vent webcam images again showed fluctuating glow and spattering from a single elongated hole deep within the Halema`uma`u vent cavity; the rim of this hole was built progressively inward by spatter making the hole smaller until two more partial collapses occurred early this morning again revealing the circulating and spattering lava pond below. Glow from the vent was visible from Jaggar Museum overnight. This morning, a near white plume is moving southwestward and low over the Ka`u Desert. The most recent sulfur dioxide emission rate measurement was 500 tonnes/day on November 3, which is elevated above the 2003-2007 average of 140 tonnes/day. Small amounts of ash-sized tephra continued to be dropped from the plume near the vent.
Past 24 hours at the middle east rift zone vents and flow field: Magma continued to degas through Pu`u `O`o crater before erupting from the TEB vent, located 2 km to the east. The most recent sulfur dioxide emission rate measurement was 1,400 tonnes/day on November 4, which is close to the 2003-2007 average of 1,700 tonnes/day. More …
Kilauea Spews More Lava
The rift zone on the eastern slopes of Hawaii’s Kilauea Volcano has been erupting since January 1983, the longest eruption in recorded history. Pu‘u ‘O‘o and the Thanksgiving Eve Breakout vent—two centers of volcanic activity—emit steam and other gases in this natural-color satellite image. Lava currently reaches the surface at the Thanksgiving Eve Breakout vent and flows southeast (towards the lower right) through a lave tube to the ocean. Small plumes of gas reveal the path of the lava. In general, the youngest lava flows are black, and older, weathered, flows are gray or brown. Surviving vegetation is bright green. The Advanced Land Imager (ALI) on NASA’s EO-1 satellite acquired this image on November 2, 2009. NASA Earth Observatory image by Robert Simmon, using EO-1 ALI data provided by the NASA EO-1 team.

VOW: Ambrym
Destructive acid rain caused by eruption
According to press reports, an eruption from Benbow Crater occurred on 10 February [1979.] Gases from the eruption caused acid rainfall on the SW portion of Ambrym Island, destroying most vegetation within 24 hours, contaminating water supplies, and burning some inhabitants. Jean-Luc Saos, Director of Mineral Resources for the New Hebrides government, reported a high concentration of HCl and sulfur compounds in the volcanic gases. Although heavy ashfalls have occurred in the area in the past, this is the first report of acid rains. More …

A hazy layer of vog—volcanic fog—overlies Malekula and a few other islands of the Vanuatu archipelago in this natural-color satellite image. The source of the vog is Ambrym, a volcano in the southeast (lower right) corner of this scene. The haze extends over the Coral Sea several hundred kilometers to the northwest. Ambrym emits sulfur dioxide—the gas responsible for the formation of vog— intermittently. (Kilauea Volcano has recently affected the residents of Hawaii with similar vog emissions.) The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite acquired this natural-color image on October 6, 2009.

Ambrym, a large basaltic volcano with a 12-km-wide caldera, is one of the most active volcanoes of the New Hebrides arc. A thick, almost exclusively pyroclastic sequence, initially dacitic, then basaltic, overlies lava flows of a pre-caldera shield volcano. The caldera was formed during a major plinian eruption with dacitic pyroclastic flows about 1900 years ago. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim. Post-caldera eruptions have also formed a series of scoria cones and maars along a fissure system oriented ENE-WSW. Eruptions have apparently occurred almost yearly during historical time from cones within the caldera or from flank vents. However, from 1850 to 1950, reporting was mostly limited to extra-caldera eruptions that would have affected local populations. Caption: GVP

News From GVP:
On 29 September, people living in Chaitén town, 10 km SW of Chaitén’s Domo Nuevo 1 (Phase I) and Domo Nuevo 2 (Phase II) lava-dome complex, noticed that the eruption column was larger. Scientists conducted an overflight and saw a third lava dome (Phase III) in the SW area of the complex, which had filled up a depression left by a collapse on 19 February.
According to news articles from 2 October, increased seismicity at Gaua was detected during the previous two weeks. Villagers living nearby reported ashfall and sulfur odors.
An explosive eruption from Galeras on 30 September prompted INGEOMINAS to raise the Alert Level. An ash plume rose to an approximate altitude of 12.3 km (40,400 ft) a.s.l. and drifted E, then N. —GVP

Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).

The skeletal remains of a young woman killed by the eruption of Mount Vesuvius in A.D. 79. The skeleton, unearthed from the ruins of Herculaneum in 1982, was named the “Ring Lady” because of the emerald and ruby rings found on the woman’s left hand. Two gold bracelets and gold earrings were also found by the woman’s side. (Source: Wikipedia)
