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.
L’unique volcan actif de l'Inde, situé sur la minuscule petite île inhabitée de Barren, frappée par le tsunami du 26 décembre 2004, dans l’archipel des îles Andaman et Nicobar, entra en éruption, comme l’indique le rapport d’actualités qui fait état du témoignage issu d’un navire des gardes-côtes indiens, qui ont vu un épais panache de fumée.

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.Read more...
