New Glowing Pit Crater At Etna Volcano In Voragine, Italy

Etna’s new pit crater in Voragine (image taken by B. Behncke from western rim of Voragine on 10 Aug 2016 at sunset)
INGV Catania volcanologist Boris Behncke visited the summit region of Etna yesterday and observed a new active pit crater, about 20-30 m wide, located in the eastern inner wall of the Voragine crater. 
 
The new vent formed on 7 Aug 2016 and has been the site of the recent weak strombolian activity (which likely continues, but bad weather is currently hiding the view).

Dangerous Explosion At Halema’uma’u Crater In Hawaii

Lava sea entry at Hawaii (image: Lava Ocean Tours)
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.
A light-colored “scar” about 20 m (66 ft) across from this rockfall is visible to the right of the spattering area on the lake surface. Rocks in the vent wall can become unstable when the level of the lava lake drops, as has been going on for the last several days. (image: HVO)
Summit lava lake explosion: 
At the summit caldera, the lava lake in Halema’uma’u crater remains active and was 40 m (131 ft) below the crater rim as of yesterday. To illustrate that it is an extremely hazardous (and forbidden) location to go to, a larger rockfall from its inner walls occurred late Saturday night and triggered an explosion that sent a shower of molten lava and rock debris of various sizes onto a broad area, 80 m (260 ft) long and 50 m (165 ft) wide, around the former Halema’uma’u overlook. Some instruments of HVO’s monitoring equipment installed there were destroyed in the explosion when hit by glowing lava bombs.
Remains of a power supply unit for one of HVO’s gravity instruments located about 24 m (80 ft) from the crater rim, destroyed during Saturday’s explosion of the lava lake (HVO)

Strong Ash Emissions Continue At Nevados de Chillán Volcano In Chile

Ash eruptions of Chillán volcano during the past 2 days
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.

VERY POWERFUL INFLUX OF ENERGY WILL STRIKE THE WEAK MAGNETOSPHERE FROM THE 12th – 21st AUGUST 2016. FURTHER EARTHQUAKES, VOLCANO ACTIVITY AND ADVERSE WEATHER WILL BE GREATLY INFLUENCED BY THE COSMIC RAYS STRIKING THE EARTH’S CORE

**BE ALERT**

Intense Ash Emissions At Dukono Volcano In Halmahera, Indonesia

Ash plume from Dukono this morning (Aqua satellite / MODIS / NASA)
Ash emissions have been intense recently, suggesting that activity at the (more or less permanently active) volcano is currently elevated. 
 
Based on satellite imagery, Darwin VAAC reported a plume at approx. 8,000 ft (2.4 km) altitude extending up to 200 km NE from the volcano.
