Worldwide Volcano News and Updates
The 3 ocean lava entries at East Lae`apuki (the largest with three visible entry points), East Kamoamoa, and Kamoamoa points (both weak) are still active at Kilauea volcano in Hawaii. The 3 corresponding alimentation systems feed surface lava flows that are active on and just below Pulama pali. The westermost one of these flows has three clusters of breakouts low on the pali and the gentle slope below. The middle branch hostsonly two breakout areas. The east branch is the largest of the three and has a number of breakouts strung along the feeding tube from low on the pali to the slope below.
All (or at least most) vents inside Pu`u `O`o are glowing, including those in West Gap. A small lava lake keeps refilling and draining back inside the East Pond Vent.
At 3:26 local time on 30 May, 2005, another strong explosion- the largest one being registered during the past 20 years,- was reported from Colima volcano. The eruption clumn reached an height of 8500 m a.s.l. and the ash plume was carried by winds towards SE and NE (at lower altitudes). Approx. 2 hours after the explosion the plume had reached a length of more than 100km. Pyroclastic flows descended the volcano's W flank.
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.

Read allColumbian 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.
