What were the sign of mount ruiz erupting?

Answer 1

Signs of Mount Ruiz erupting included increased seismic activity, such as frequent earthquakes and volcanic tremors, which indicated rising magma. Additionally, there were observable changes in the volcano’s fumaroles, with increased gas emissions and temperature fluctuations. Ash plumes and changes in the landscape, like ground deformation, also suggested an impending eruption. These signs culminated in the catastrophic eruption in 1985, which had devastating effects on nearby communities.
