Identification of structural controls in an active lava dome with high resolution DEMs:Volcán de Colima, Mexico [PDF]
Geophysical Research Letters, 2012 Monitoring the topography of active lava domes is critical for detecting changes that may trigger or influence collapse or explosive activity. Internal dome structure and conditions are more difficult to elucidate, but also play vital roles.

Insights into the recurrent energetic eruptions that drive Awu, among the deadliest volcanoes on Earth [PDF]
Natural Hazards and Earth System Sciences, 2020 The little-known Awu volcano (Sangihe Islands, Indonesia) is among the deadliest, with a cumulative death toll of 11 048. In less than 4 centuries, 18 eruptions were recorded, including two VEI 4 and three VEI 3 eruptions with worldwide impacts ...

Squeezing out plastic lava blocks on Young Shiveluch volcano (Kamchatka) in 2020–2021
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021 Volcano Young Sheveluch is one of the most active volcanoes in Kamchatka. Since August 1980 to the present time, an extrusive dome has been growing in the crater of the volcano. Plastic lavas in the form of large ribbons were noted on the dome already in

The longevity of lava dome eruptions [PDF]
Journal of Geophysical Research: Solid Earth, 2016 AbstractUnderstanding the duration of past, ongoing, and future volcanic eruptions is an important scientific goal and a key societal need. We present a new methodology for forecasting the duration of ongoing and future lava dome eruptions based on a database (DomeHaz) recently compiled by the authors. The database includes duration and composition for

LAVA DOME CHANGES DETECTION AT AGUNG MOUNTAIN DURING HIGH LEVEL OF VOLCANIC ACTIVITY USING UAV PHOTOGRAMMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Lava dome changes detection during increasingly high volcanic activity are essential for hazard assessment purposes. However, it is challenging to conduct direct field measurement due to safety reason.

Structural weakening of the Merapi dome identified by drone photogrammetry after the 2010 eruption [PDF]
Natural Hazards and Earth System Sciences, 2018 Lava domes are subjected to structural weakening that can lead to gravitational collapse and produce pyroclastic flows that may travel up to several kilometers from a volcano's summit.
