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



KLIUCHEVSKOI Kamchatka Peninsula, Russia 56.06°N, 160.64°E; summit elev. 4,835 m (7.8 km)

during 11-18 February, ash plumes rising to 7.8 km during 12-14 February, phreatic bursts occurring when lava flows contacted a glacier seen on 12 and 13 February, during 12-16 February, volcanic bombs hurled 300-500 m above the crater, Strombolian activity in the crater, and lava traveling into Krestovsky channel on the volcano's NW flank, during a flight on 16 February a mudflow seen extending 27 km, a lava flow melting a large section of Ehrman glacier



SHIVELUCH Kamchatka Peninsula, Russia 56.653°N, 161.360°E; summit elev. 3,283 m (7.4 km)

during 11-18 February, ash plumes possibly rising to a maximum height of 7.4 km on 17 February, possible weak ash-and-gas explosions and hot avalanches during the week



ST. HELENS Washington, USA 46.20°N, 122.18°W; summit elev. 2,549 m (3.5 km)

during 16-22 February growth of the new lava dome inside the crater continuing, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash, a A GPS unit deployed on 16 February on the E arm of the glacier within the volcano's crater moved northward about 1.2 m per day, this rapid rate of flow consistent with the thickening of the glacier resulting from its compression between the growing lava dome and E crater wall, a thermal imaging flight on the 16th suggesting that a longitudinal crack developing along the top of the new lava dome, on the afternoon of 18 February a rockfall off the lava dome producing an ash plume rising several hundred meters above the crater rim, the extensive cracking on the long, smooth, whaleback-shaped lava dome suggests increased rockfall activity and similar small plumes in the coming weeks; recent airphotos as of 1 February with the new lava dome, uplifted area of crater floor, and deformed glacier ice a combined volume of about 38 million cubic meters, almost one-half the volume of the old lava dome



VENIAMINOF Alaska Peninsula, USA 56.17°N, 159.38°W; summit elev. 2,507 m (?)

during 11-18 February low-level Strombolian eruptive activity continuing based on seismic data and satellite imagery, no ash emissions observed above the cloud cover





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





ANATAHAN Mariana Islands, central Pacific Ocean 16.35°N, 145.67°E; summit elev. 788 m (low)

eruptive activity declining steadily during the week of 14 February to less than 5% of the peak level during the eruption beginning 5 January, ash eruptions continuing, the 2003 crater floor almost entirely covered by fresh lava to a diameter of about one kilometer, on 21 February seismic and acoustic records showing very low levels of activity, at 1515 on 17 February a plume of steam and vog (fog composed of volcanic fumes) extending about ~170 km SW of Anatahan



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

during 16-21 February several small explosions producing ash plumes rising to low levels; plumes drifting predominately SE and W



EGON Lesser Sunda Islands, Indonesia 8.67°S, 122.45°E; 1,703 m (low)

as of 17 February recent eruptive activity prompting the local government to evacuate hundreds of residents living near the volcano



KARANGETANG [Api Siau] Siau Island, Indonesia 2.47°N, 125.29°E; summit elev. 1,784 m (0)

on 26 February a lava flow traveling 600 m from crater, lava avalanches in the same area traveling as far as 1,200 m down the volcano's flank, at 1030 a pyroclastic flow traveling ~3,400 m reaching the sea



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

on 21 February a new ocean entry named East Lae`apuki starting, located between the other two ocean entries (Ka`ili`ili and West Highcastle) active since 31 January 2005, the first time three ocean entries active since early 2003, during 17-22 February surface lava flows visible on the volcano



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

mild eruptive activity observed from Manam's Southern rater during 18-21 February, weak-to-moderate ash explosions the crater rising a few hundred meters above the crater and drifting E and SE, depositing fine ash in areas downwind, main Crater emitting white vapor



PITON DE LA FOURNAISE Réunion Island, Indian Ocean 21.23°S, 55.71°E; summit elev. 2,631 m (0)

a new period of heightened seismic activity beginning on 17 February around 1100, events decreased, but recommenced at 1438 with several hundreds of events, strong deformation recorded at the same time by tiltmeters and the extensometer network, eruption tremor around 1835, becoming strong at 1850, and lava flows were observed in the Grand Brûlé area, the eruption ending on 19 February



RABAUL New Britain Island, Papua New Guinea 4.271°S, 152.203°E; summit elev. 688 m (1.7 km)

during 1-21 February eruptions of ash clouds fairly frequently at Rabaul caldera's Tavurvur cone, ash clouds rising a few hundred meters, drifting SE, and depositing ash mainly offshore


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

volcanic activity were at low levels during 16-22 February, low-energy gas, steam, and ash plumes emitted; ash on 24 February to 7.8 km





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