Merapi volcano (Central Java, Indonesia): Volcanic Alert Level raised to Level 3
PVMBG reported that an alert level for the volcano was raised from the level 2 to level 3 as an increase of seismicity has been recorded. After the powerful eruptions on 21 June a seismicity remains elevated including shallow volcano-tectonic earthquakes. Additionally, instruments detected significant ground deformation. The warning bulletin states that ballistic impacts of volcanic bombs…
Barren Island volcano (Indian Ocean, India): explosive eruption today
After a one year calm period with little or no activity, it seems to have picked up again since around 6 November last year. Today at around 06:45 local time Volcanic Ash Advisory Center (VAAC) Darwin recorded an explosive eruption at the Indias’s only active volcano that generated an ash plume, which reached approx. 5,000 ft (1,500 m) altitude and drifted SW.

How is drone technology advancing our understanding of future volcanism?
Improved early warning systems are crucial for minimising loss of life and effectively planning for volcanic emergencies. Typically, volcanologists use seismic monitoring as their main indicator of imminent volcanic activity. As technology advances, alternative early warning system methods are being explored by volcanologists. A better understanding of the chemistry within a volcanic plume,…
