RECENT VOLCANIC ERUPTIONS



Northern Ash and Gas Eruptions north of latitude 23°N.





GRÍMSVÖTN northeastern Iceland 64.42°N, 17.33°W; summit elev. 1,725 m (9 km)

the eruption on 1 November around 2200 greatly reduced by 4 November, the eruption plume greatly reduced, consisting mostly of steam, ash and fragmented ice ~to a height of 2-4, on 2 November a phreatomagmatic eruption in progress from a short (less than 1-km-long) eruptive fissure at 64.40°N, 17.23°W with a continuous plume to an elevation of about 9 km and periods of high explosive activity with maximum plume heights of 12-14 km above the volcano, air traffic disrupted with an area of 311 thousand square kilometers closed to flights until the morning of 4 November, eruptions containing ash ceasing around 1700 on 4 November



RUAPEHU North Island, New Zealand 39.28°S, 175.57°E; summit elev. 2,779 m (0)

on 2 November volcanic tremor to the highest level for at least 12 months, the tremor declining slowly



ST. HELENS Washington, USA 46.20°N, 122.18°W; summit elev. 2,549 m (3.3 km)

during 3-8 November seismicity at a low level compared to early in the unrest, consistent with a continuing, slow rise of magma driving uplift of the crater floor and feeding a surface extrusion of lava, the lava reaching the surface gas poor, reducing the probability of highly explosive eruptions in the near term, the finer particulates from rockfalls within the steam plume about 800 m above the crater rim, or 3.3 km



SHIVELUCH Kamchatka Peninsula, Russia 56.653°N, 161.360°E; summit elev. 2,283 m (6 km)

during 29 October-5 November, based on seismic data, possible ash-and-gas explosions up to 6.5 km on 30 October and 2-4 November, ash-and-gas explosions up to 3.5-5.5 km noted all week, according to video data ash-and-gas explosions to 3.5-6 km during 28-30 October, and 1 and 3-4 November



SPURR southwestern Alaska, USA 61.299°N, 152.251°W; 3,374 m (0)

elevated levels of seismicity continuing during 29 October to 2 November, an earthquake swarm on 4 November, airborne measurements of volcanic gas from the volcano on 29 and 30 October indicating no significant change in the amount of carbon dioxide or sulfur-bearing gases compared to September, no unusual activity observed on satellite or web-camera images





Equatorial Ash and Gas Eruptions at less than 23°N or S





COLIMA western México 19.514°N,103.62°W; summit elev. ~3,850 m (?)

during 5-7 November block-lava flows continuing down W, NW, and S flanks since 30 September, several explosions daily



FUEGO Guatemala 14.47°N, 90.88°W; summit elev. 3,763 m (low level)

during 3-5 November avalanches of incandescent volcanic material originating from two areas, afew explosions producing low-level plumes, avalanches from the fronts of lava flows



KILAUEA Hawaii, USA 19.43°N, 155.29°W; summit elev. 1,222 m (0)

lava from Kilauea's PKK flow entering the sea the evening of 4 November, the first since the Banana lava delta in early August 2004, on the morning of 5 November the entry small but vigorous, by 8 November the new lava delta ~100 m wide along the shore and reached 15 m seaward from the front of the old Lae`apuki delta, during 4-8 November all vents in the

crater of Pu`u `O`o incandescent



MANAM offshore New Guinea, Papua New Guinea 4.10°S, 145.06°E; summit elev. 1,807 m (3 km)

ash visible on satellite imagery on 8 and 9 November at a height of ~3 km



NYIRAGONGO Democratic Republic of the Congo 1.52°S, 29.25°E; summit elev. 3,469 m (4.9 km)

an eruption sometime earlier than 0400 on 3 November, a thin W-drifting plume visible on satellite imagery on 3 and 4 November at a height around 3.6-4.9 km



SANTA MARÍA Guatemala 14.756°N 91.552°W; summit elev. 3,772 m (4.8 km)

during 3-8 November weak-to-moderate explosions producing gas-and-ash plumes to ~4.8 km, many explosions accompanied by block-and-ash avalanches from the NE and SW edges of Caliente dome, satellite imagery on 3 November showing a possible ash-bearing plume at a height of ~5 km



SOUFRIÈRE HILLS Montserrat, West Indies 16.72°N, 62.18°W; summit elev. 1,052 m (0)

during 29 October to 5 November volcanic remaining elevated, thought to be related to rainfall, the sulfur-dioxide flux averaging about 290 metric tons per day, with a high of 440 metric tons on 30 October



TUNGURAHUA Ecuador 1.47°S, 78.44°W; summit elev. 5,023 m (low level)

volcanic activity during 4-7 November at relatively low levels, characterized by a few long-period earthquakes and small explosions, emissions mainly steam, gas, and small amounts of ash





All ash elevations are in km above sea level (a.s.l.) and times are converted to UTC.
