Lava domes form at the top of many volcanoes when viscous lava erupts, and when they become unstable, they can collapse and cause a hazard. The researchers\u2019 intention is that by understanding the inner processes, volcano collapses can be better forecasted.<\/p>\n
Catastrophic volcano collapses and associated explosions, <\/span>such as<\/span> the collapse of Mt St Helens in 1980, are widely considered as unpredictable. This is because the physical properties, stress conditions, <\/span>\u00a0internal structure of volcanoes<\/span>,<\/span> and the lava domes on top of many volcanoes are not well understood and can adjust precipitously from one day to another.<\/span><\/span>\u00a0<\/span><\/p>\n This collaborative study, led by Gadja Mata University in Yogyakarta Indonesia, includes researchers from Uppsala University in Sweden<\/a>, and from the German Research Centre GFZ at Potsdam<\/a>. This scientific collaboration means that researchers can now explain summit dome instabilities and associated pyroclastic flows at Merapi volcano, Indonesia.<\/p>\n The study combines novel drone-based photogrammetry surveillance over several years with mineralogical, geochemical, and mechanical rock strength measurements.<\/p>\nWhat has this study revealed?<\/h3>\n
