KVERT reported that during 26 March-2 April seismic activity from Kliuchevskoi was above background levels, and gas-and-steam plumes containing small amounts of ash were sometimes seen rising to an altitude of 5.3 km (17,400 ft) a.s.l. Strombolian activity ejected material 300 m above the crater and lava continued to flow down the flanks. Satellite imagery revealed a large daily thermal anomaly from the volcano, and gas-and-steam plumes that drifted about 70 km E on 30 March.
Wed, 31 Mar 2010, 06:00During 31 March-6 April, HVO reported incandescence from a 60-m-wide active lava surface about 200 m below a vent in the floor of Kilauea's Halema'uma'u crater. The lava surface circulated and both rose and drained through a pit in the cavity floor; a few times the level fluctuated between 235 and 260 m below the surface. Plumes from the vent drifted mainly SW, dropping small amounts of ash downwind.

The Icelandic Met Office reported that around 1900 on 31 March a new fissure at Eyjafjöll opened NE of the first fissure that began erupting on 20 March. Activity from the second fissure was not preceded by detectable seismicity. According to a news article, the fissure was about 300 m long, and about 200 m away from the first fissure.

The active lava lake inside Halema'uma'u crater on Kilauea volcano (27 March 2010)
Following another period of summit inflation, the level of the lava lake inside Halema'uma'u has risen, producing bright red glow above it, as observed last night.
Mon, 29 Mar 2010, 04:22
After the first day of the eruption the activity concentrated on a 300 m. long section of the fissure. With lava fountains 100-200 m high and the formation of a row of new cinder cones with 4-6 active craters, the activity has been rather constant. The lava flows have been running in 2 directions, towards the northeast and west, down into steep snowfilled canyons, with spectacular lavafalls and steam explosions from melting snow. Finally the eruption has now turned into a tourist show.
Wed, 24 Mar 2010, 06:00Based on information from JMA, the Tokyo VAAC reported an explosion from Suwanose-jima on 29 March. Details of possible resulting plumes were not reported.
