Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Yesterday's eruption sent lava fountains several hundreds of meters into the air and spraying from several vents in different directions. The eruption is already ending with an abrupt drop of volcanic tremor and decreasing lava emission. Judging from the few webcam images with at least some visibility, it appears that the activity was more effusive (lava flows) than explosive (lava fountains) with the main phase being around 23:20 local time.

Shiveluch (Kamchatka): A series of larger dome collapse events took place today, producing large pyroclastic flows and an ash plume that rose to about 30,000 ft (10 km) altitude.

Nishino-shima (Volcano Islands, Japan): The new island continues to erupt and grow, increasing its chances of long-time survival by the day. The active vent on the islet continues to be in strombolian eruption and has by now built a new cone that is higher than the main island itself (which is 38 m). Lava flows have significantly enlarged the island to the SE where a plateau is being built. During the 10 days, it has more than doubled its surface
