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 (3.4 km)

eruption on 16 October at 0306, producing a SE-drifting ash cloud higher than 3.4 km, and on 18 October at 0117, producing a N-drifting plume to a height of ~3.4 km



KARYMSKY Kamchatka Peninsula, Russia 54.05°N, 159.43°E; summit elev. 1,536 m (?)

seismic data suggesting ash-and-gas plumes to heights of 2.5-3 km on 9, 12, and 13 October, ash plumes visible on satellite imagery on 11 and 12 October, extending E then ESE 80 and 50 km, respectively



ST. HELENS Washington, USA 46.20°N, 122.18°W; summit elev. 2,549 m (2.6 km)

during 13-18 October seismicity low and growth of the new lava dome inside the volcano's crater continuing, on 13 October low levels of sulfur dioxide and hydrogen sulfide, but no carbon dioxide, on 14 October visual observations and thermal imaging of the crater showing enlargement of both the section of intense deformation and uplift on the S side of the 1980-86 lava dome and the new lobe of lava in the W part of that area, temperatures of almost 700 degrees C in parts of the new lobe from which ash-rich jets rose tens of meters, abundant steam continuing, on the 14th only sulfur-dioxide flux detected and no detectable carbon dioxide or hydrogen sulfide, Global Positioning System (GPS) measurements on 15 October indicating only minor deformation of the northern part of the 1980-86 dome and no deformation of the volcano's outer flanks, through 18 October seismicity consistent with a continuing rise of magma, lava reaching the surface gas poor



SHIVELUCH Kamchatka Peninsula, Russia 56.653°N, 161.360°E; summit elev. 2,283 m (3.5 km)

during 8-15 October, based on seismic data, weak ash-and-gas explosions and hot avalanches all week, ash plumes to 3.5 km on 7 and 12 October, weak gas-and-steam activity on 11 and 12 October



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

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

during 13-18 October surface lava flows visible, a M 4.5 earthquake on 13 October at 2318 about 6 km S of Pu`u `O`o at a depth of ~9 km--the earthquake permanently offseting the Pu`u `O`o tiltmeter and several others on the volcano, but little deformation occurring



MAUNA LOA Hawaii, USA 19.475°N, 155.608°W; summit elev. 4,170 m (0)

during the week ending 13 October, 110 earthquakes under the summit, up from 47 for the week ending 6 October, through 13 October more than 730 earthquakes related to the ongoing seismic activity

seismicity increasing during 18-19 October



PACAYA southern Guatemala 14.38°N, 90.60°W; summit elev. 2,552 m (2.8 km)

activity at Pacaya during 14-18 October not significantly changed in 2 months, white plumes to ~2.8 km



SANTA MARÍA Guatemala 14.756°N 91.552°W; summit elev. 3,772 m (12.8 km)

during 14-18 October weak-to-moderate explosions producing plumes to a height of ~12.8 km, a pyroclastic flow on 17 October at 1349 producing a steam-and-ash plume to ~4.6 km upon contact with dammed water (Height not verified on Washington VAAC report. See SPECIAL NOTE.)



SOPUTAN Sulawesi, Indonesia 1.11°N, 124.73°E; summit elev. 1,784 m (2.4 km)

eruption on 18 October at 0241, producing an E-drifting ash cloud to a height of ~2.4 km, at 1015 incandescence visible, later that day a "lava avalanche"



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

volcanic activity at slightly elevated levels during 8-15 October as since mid-September 2004, sulfur-dioxide flux measurements only possible on 2 days-156 and 553 metric tons per day w



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

volcanic activity during 13-18 October at relatively low levels, emissions mainly steam and gas
