Of all the people killed by volcanoes between 1975 and 2000, 86% died in Colombia. Most of these people died in the town of Armero due to mud flows from the Nevado del Ruiz volcano, on 13th November 1985 - almost 22 thousand deaths were recorded there. Volcanic activity can endanger human life in various ways: mud flows, lava flows, pyroclastic flows (super-heated toxic gas and debris), collapses and landslides, and the settling of ash and dust. Earthquakes and tsunamis caused by volcanic activity are not included here. There were no deaths caused by volcanoes between 1975 and 2000 in 183 of the 200 mapped. Volcano-related deaths occurred most frequently in Indonesia, in 9 of the 26 years shown. |
