$Nearly 10 yrs of drone surveys at Merapi volcano highlights the importance of hydrothermal weakening and structures hidden beneath younger lavas. A fracture system that formed in 2012 was subsequently buried under new lava in 2018. Only a year later, the new lava dome that formed in 2018 showed signs of instability and collapse along the previously buried fracture system, implying that hidden weaknesses may be a key factor in controlling hazardous volcano collapse.
