Roundup of Global Volcanic Activity

Klyuchevskoy (Kamchatka): The eruption of the volcano continues with little changes: although the volcano is in clouds most of the time, occasional satellite and webcam views allow to determine that the lava flow on the SE flank remains active and strombolian activity continues in the summit crater. As a result, a strong thermal signal is visible on satellite-based infrared-radiation measurements. From time to time, this activity also generates small to moderately-sized ash plumes (by explosive activity and/or avalanches from the lava flow).

Kilauea (Hawai'i): A second lobe of the 61G lava flow in the coastal flat has crossed the Emergency Access road at a location about 500 m (1,640 ft) west of the main flow and entered the ocean during the night 8-9 Aug. Thus, there are now two ocean entries at Kamokuna; the first one which had been active since 26 July and gradually widened to now almost 300 m (820 ft) and the new one west of it, making the total area of the ocean entry close to half a mile long, with gaps in between.

Nevados de Chillán (Central Chile): The volcano continued to produce mild to relatively strong ash emissions once or twice per day on average. Plumes have been reaching heights of 2 km and the Chilean authorities have increased the exclusion zone near the volcano (which is part of a popular skiing area) from 2 to 3 km radius around the crater.
