RECENT VOLCANIC ERUPTIONS



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





ASAMA Honshu, Japan 36.40°N, 138.53°E; summit elev. 2,560 m

a loud explosion 14 November at 1159, the eruption as mid-sized, 3 on a scale of 5 in terms of power of the explosion, no ash plume observed due to cloudy weather, falling rocks observed over a large area on the slopes of the volcano



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

elevated levels of volcanic tremor possibly signaling the start of another Crater Lake heating cycle



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

growth of the new lava dome inside the crater of St. Helens continuing and accompanied by intermittent emissions of steam and ash, when weather permitted, a plume rising passively and drifting out of the crater with minor ash, gas emission suggesting the lava reaching the surface was gas-poor and unlikely to generate highly explosive eruptions in the near term, recent extrusion-rate estimates of ~4 cubic meters per second slightly lower than those in mid-October. These rates, which are based on the volume of deformed crater floor and the amount of airborne sulfur dioxide measured during gas-monitoring flights, have uncertainties associated with their calculation. Volcanoes like St. Helens are expected to undergo slight variations in their extrusion rates during eruptive cycles. This change is small and does not indicate a notable change in the eruptive process.



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

during 5-12 November, based on seismic data, possible ash-and-gas explosions up to 6.5-7 km on 5, 7, 9, and 11 November, during the week gas-dominated plumes to ~4 km and those bearing ash to 3.5-6 km



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

elevated seismicity during 5-12 November, no unusual activity observed in satellite or web camera images





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





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

a strombolian eruption beginning on 10 November at 1200 and lasting until 11 November at 0915, the ash column from the eruption rising ~7.8 km, and perhaps as high as ~10.8 km around 0732 according to a pilot account




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

during 10-15 November block-lava flows continuing, several explosions daily, satellite imagery from 2215 on 10 November indicating a plume to a height of ~5 km, consisting mostly of steam and a little ash, emitted around 2210



FUEGO Guatemala 14.47°N, 90.88°W; summit elev. 3,763 m

during 10-15 November avalanches of incandescent volcanic material towards the major ravines on the volcano's flanks, small explosions expelling incandescent lava to heights of 3.9 km, steam plumes from fumarolic activity reaching heights of ~4.4 km



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

lava from Kilauea's PKK flow continuing to enter the sea during 10-16 November at a newly formed lava delta at the eastern Lae`apuki entry area, on 16 November the delta growing along a wide front, a new arm of the delta-feeding flow forming ~100 m farther E and at their current rate of advance they could enter the sea within a day, all vents in the crater of Pu`u `O`o

incandescent



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

during 10-15 November weak-to-moderate explosions, causing the collapse of a small sector of the SW edge of the Caliente dome, a pyroclastic flow from that area on 12 November, on 14 November at 2012 a tectonic earthquake with a lava-flow collapse SW of the Caliente dome and triggering a pyroclastic flow



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

during 8-15 November, volcanic activity elevated, reliable data only available for two days, yielding SO2-flux estimates of 141 and 501 metric tons per day



TUNGURAHUA Ecuador 1.47°S, 78.44°W; summit elev. 5,023 m

volcanic activity at relatively low levels, characterized by small to moderate explosions, emissions mainly steam, gas, and small amounts of ash, on 15 November incandescence observed in the crater of the volcano and explosions generating steam columns with moderate ash content to ~7 km





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

SPECIAL NOTE:



Growth of Dome at Mount St. Helens (See Volcanos also.)



Good viewing conditions on 10 November revealed continued growth of the lava dome. Current estimates are that the welt, the broad area of

deformation, is about 600 m in diameter. The new lava dome, which occupies the central and western parts of the welt, is about 400 by 180 m. The highest point on the new lava dome is about 250 m above the former surface of the glacier that occupied that point in mid-September. Maximum surface temperatures on the new dome remain at about 700 degrees Celsius. GPS instruments on the welt show rates of movement of up to several meters per day, while GPS instruments on the 1980-86 lava dome show movements of up to 1-2 cm per day northward, away from the growing welt and new dome.





Comments or questions are welcome.
