During 30 May-5 June HVO reported that the circulating and spattering lava lake periodically rose and fell in the deep pit within Kilauea's Halema'uma'u Crater, rising as high as the inner ledge about 60 m below the crater floor. Periodic measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash and Pele's hair onto nearby areas. The level of the lava pond in a small pit on the E edge of Pu'u 'O'o crater floor rose back into view. Read all- More about Kilauea volcano

INGEOMINAS reported that on 17 May ash emissions originating from an area N and W of the cone within Galeras's main crater rose 200 m above the crater rim. During 26-27 May ash plumes rose 800 m above the crater; ashfall was reported in Sandona (13 km NW). Ash emissions occurred on 2 June, and on 5 June plumes rose 1 km and drifted W.

We're always happy to receive some feedback about our tours. Geology student Isabel from Tübingen writes about the recent tour on Santorini: "This trip, the first holiday since the beginning of my studies, fulfilled everything I had dreamed about: hiking, geology, and culture in a most pleasant mix. The trip was both relaxing and inspiring as well. ... " - More about Santorini volcano

A swarm of 14 small to very small mostly very shallow quakes occurred at Katla volcano yesterday and today. Epicenter depths were reported between 0.1 and 12.2 km. Judging from the depth and magnitude of the quakes, the most likely cause for the seismic swarm are adjustments of the hydrothermal system under the icecap, and probably not magmatic intrusions (which would be possible indicators of a future new eruption).

After a week-long deflation on Kīlauea, lava flows which had reached within .5mi/750m of the ocean finally felt the pressure relief and came to a pause. At the time of this writing there is still low pressure on the volcano, and the longer this continues the more likely that the plumbing system will be disrupted and that lava will re-emerge in a new location -- whether on a new point up the lava tube, or even all the way back to Pu`u `O`o crater on the east rift zone. Magma continues to come into the volcano, as evidenced by continued extension, and without an outlet, sooner or later something will have to give! While there is no red lava visible on the coast today, there is still bright glow from the newest summit vent in the National Park. This is a crucial period of change for the volcano, and we all await what will happen next!- More about Kilauea volcano
