seismic activity above background levels during 15-22 April: during 14-15 April, possible ash-and-gas explosions rising to 1.5 km, Strombolian activity on the evening of 20 April; volcanic bombs rose to 50 m above the crater, on 21-22 April ash-and-gas bursts rose 300-400 m above the crater, ash falling to the NE on 21 April

SHIVELUCH Kamchatka Peninsula, Russia 56.653°N, 161.360°E; summit elev. 3,283 m (moderate)
during 15-22 April gas-and-steam plumes to ~3.7 km above Shiveluch's lava dome, satellite imagery showing a large thermal anomaly at the lava dome on 16, and 18-21 April, and a small anomaly associated with a pyroclastic flow on the 19th

ST. HELENS Washington, USA 46.20°N, 122.18°W; summit elev. 2,549 m (low)
during 20-25 April 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; the current eruption thus far a total topographic change in the crater equivalent to about two-thirds the volume of the old lava domel; the rate of extrusion at the N end of the new lava dome continuing at about 2-3 meters per day

ash seen on 25 April around 1326 at a height of ~7.9 km drifting S

SANTA MARÍA Guatemala 14.756°N, 91.552°W; summit elev. 3,772 m (5 km)
several explosions during 21-25 April with lava avalanches down the SW flank of Caliente Dome, ash plumes to ~5 km; explosions on 25 April producing pyroclastic flows traveling S down Caliente Dome

SOPUTAN Sulawesi, Indonesia 1.11°N, 124.73°E; summit elev. 1,784 m (2.1 km)
on 19 April at 2230 a plume reaching ~2.8 and drifting SE; in addition, lava
fountains rose ~200 m above the volcano; during 20 April at 0920 to 21 April at 0100 lava fountains rising 75-100 m above the summit and rapid dome growth, by 21 April the lava dome about 250 m E and 200 m SW; on 22 April a "white ash plume" ~100 m above the summit, on 23 April a "dark gray ash" plume to ~150 m and drifting NE; ash eruptions through 24 April, producing plumes to ~300 m above the summit

SOUFRIÈRE HILLS Montserrat, West Indies 16.72°N, 62.18°W; summit elev. 1,052 m (low)
beginning on 15 April vigorous steam-and-ash venting on the NW side of crater; light ashfall W of the volcano during 23-24 April; an average of 365 metric tons of sulfur dioxide was measured daily, below the long-term average for of 500 metric tons per day

TUNGURAHUA Ecuador 1.47°S, 78.44°W; summit elev. 5,023 m (low)
during 20-25 April volcanic activity at relatively low levels with low-energy gas-and-steam plumes emitted

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