Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): Over the past days, Stromboli has returned to normal levels of activity with frequent, mostly small to medium-sized explosions and low to medium tremor. Small lava overflows and frequent rockfalls still occur.

Pavlov (Alaska Peninsula, USA): The eruption continues with no significant changes. Small lava fountaining, explosions, and the explosive interaction of the lava flow with snow and ice generate a plume of steam, ash, and gas, occasionally reaching up to 22,000 ft. above sea level, and extending primarily southeast from the volcano over the North Pacific Ocean visible in satellite images. Minor ash fall is likely occurring on the north, east and southeast flanks of the volcano and possibly on parts of Pavlof Bay and adjacent waters southeast of the volcano.

Concern about risky activity at Kilauea

U.S. Geological Survey officials are concerned over what they say is risky behaviour by visitors to Kilauea Volcano at Hawaii Volcanoes National Park. The problem is that people continue to get too close to Kilauea's current ocean entry, approaching both by land and sea.

Areas of ocean entry are dangerous places. Lava entering the sea builds a platform of new land known as a lava delta, which appears stable but is not. Lava deltas can collapse without warning. Kayakers visiting the volcano on the Big Island recently paddled just feet from lava streaming into the ocean. They then went ashore and walked across new land built by the ocean entry and scooped molten lava with their paddle.
