India's only active volcano, the tiny uninhabited Barren island in the Dec. 2004 tsunami-hit Andaman and Nicobar archipelago has started an eruption as news reports state after an Indian coast guard ship had sighted a thick plume of smoke.
No further activity of the Karthala Volcano has been reported since May 24 and the eruption can be considered to be over by now.
About 10,000 persons had been displaced but returned to their homes immediately after the eruption declined. Work is underway to restore potable water and sanitation facilities to an estimated number of about 40,000 affected by volcanic ash fallout.
As the Alaska Volcano Observatory reports, seismic activity and the height of ash explosions increased during the past week at Karymsky. Ash-and-gas plumes rose to ~3.5 km above the crater (16,500 ft a.s.l.) and fresh ash fell on the W and E sectors of the volcano. A thermal anomaly continues to be visible from satellite imagery.
Columbian authorities have ordered the evacuation of 9000 people living on the slopes of Galeras volcano near the border with Ecuador, after monitoring scientists warned of that the volcano might erupt again soon.
Galeras last had a minor eruption November 2004, wich caused little effect on the surrounding populations. In 1993, a small eruption inside the crater had made Galera infamous, because it killed 10 scientists who had climbed up to its crater and were surprised by the eruption during their stay.

At 1910 local time on May 23, 2005, a major explosion took place at Colima volcano, one of the largest during the past 5 years. A vulcanian eruption produced an ash cloud of 2-3 km above the crater, which in parts drifted towards the west, and in parts collapsed to form strong pyroclastic flows, that travelled down the canyons of San Antonio and Monte Grande. These flows reached distances of up to 4-5 km. Ballistic projectiles landed around the volcano at distances of 3-4 km.

Lava emission from La Cumbre volcano, Fernandia Island (Galapagos) has been rapidly declining since May 18th and almost stopped on May 19th. Unless it restarts with new lava emissions, the eruption was relatively short-lasted.

The Kamchatka Volcano Eruption Response Team (KVERT) reported that seismic activity of Klyuchevsky volcano is at background level, but a thermal anomaly is visible on satellite imagery at the summit crater. The team considers the possibility of explosions that produce ash plumes that reach as high as 6 km (or 19,700 ft).

The lava dome inside Sheveluch volcano's summit crater continues to grow. Although no explosive activity was registered during the past week, stronger eruptions that produce ash plumes several km in height could occurr at any time.

During the past 48 hours, volcanic tremor beneath Anatahan increased to eight times the pre-May 18th background level. Discrete earthquakes are largely absent from the seismic record and acoustic records show no apparent explosive events. Satellite imagery indicates ash propagation at 10,000 feet beginning to shift from the southeast to the northwest. Vog and steam is apparent from visual imagery in two regions, the first between 50 and 55 nautical miles northeast of Anatahan, and a wider swath extending from 45 to 130 nautical miles southeast of Anatahan.

As the Volcanological Survey of Indonesia reports, seismic activity at Krakatoa has increased during the past days, and the alert level has been risen to 2 (out of 4).

La Cumbre volcano on Fernandia Island, in the Galapagos Islands, erupted on May 13, with a steam and ash cloud up to 7 km high. Lava flows are travelling down the volcanoe's SW flank and some of them have reached the sea.

Lascar volcano erupted last week, as the Buenos Aires VAAC reported: seen on satellite imagery early on 4 May, Lascar volcano in Chile sent an ash plume into the 4.5-10.6 km a.s.l. range (15,000-35,000 feet), where it was moving to the SE.

Between 28 April and 4 May 2005, almost continuous emissions of thick white to gray ash-clouds were observed rising about 700-800 m above the summit crater.
Glow was visible during nights; strombolian activity with projections of incandescent lava became frequent in early May.

Since the eruption on 19 Aril, 2005, the lava dome continues to grow, producing frequent small block and ash flows (avalanches of hot lava from the unstable parts of the dome).

Colima remains in a highly active state with a growing lava dome. Typically, a few relatively strong explosions are occurring per day that at the moment do not threaten the volcano's surroundings. Stronger eruptions able to produce pyroclastic flows could occur at any time.

Activity at Popocatépetl volcano is a low levels, although a low alert level and an exclusion zone around the volcano is being maintained for safety reasons, since an intensification of the eruption at any time cannot be excluded. During the past days, CENAPRED (the monitoring system of Popocatépetl volcano) registered a number of weak steam and gas emissions. In an aerial photograph taken on January 14th, subsidence is observed in the inner crater and no lava dome at the bottom of the crater could be observed.

Sheveluch volcano remains in strombolian activity, with explosions that produce ash plumes some 1-2 km above the crater. At the moment, scientist have no data on the seismic activity in the area of the volcano, because the station at Baidarnaya, eight kilometers from the peak of Shiveluch, was destroyed by a lahar on February 27-28.

The crater terrace of Stromboli volcano seen from its W rim.
During repeated excursions of the VolcanoDiscovery Europe team to Stromboli volcano in late April 2005, the volcano showed "normal" strombolian activity at medium levels:
The oval-shaped, active crater terrace consists now of 3 clusters of vents, which corrispond to the former NW (towards Ginostra), Central and NE craters (towards the village of Stromboli). During our visits, no activity other than weak steaming was observed from 3 small pits inside the NW crater. The central crater complex has two open glowing pits that were observed spattering weakly, throwing bombs to up to 10-20 m height. A third vent at the northen end of the central crater is a circular cone about 15m tall, with a small round opening, about 1-2 m large, that was glowing and exploded from time to time, about every minutes, throwing a candle-like jet of lava to about 150 m, accompanied by a loud detonation noise that caused impressive echoes in the summit area (these echoes sometimes went back and forth between the Vanori and the Pizzo headwalls up to 5 times).
The NE crater complex, heavily changed by the collapse of 30 Dec. 2002 and subsequent events, consists of at least 2 vents, of which one (to the W) is another small cone that we observed explode irregularly, at intervals of several hours, and throwing jets of lava to 100-150m, while the more active vent(s?) to the E end of the crater, not visible from Pizzo and the crater rims), showed beautiful strombolian activity every 10-30 minutes, with almost noiseless, wide sprays of lava to 50-100 m that covered the outer flank of the NE crater with bombs. During our observation times, no explosion was strong enough to throw glowing material to the steep flank of the Sciara del Fuoco.
