AB - ABSTRACT: Volcanic eruptions in Latin America have claimed about 61,000 lives since 1600 A.D. and the region's volcanoes are responsible for about a quarter of the world's fatalities from this type of hazard. Nearly all loss of life from volcanism in Latin America is due to pyroclastic surges, pyroclastic flows, and lahars of volcanic mudflows. Lahars generated during the 13th November, 1985 eruption of Nevado del Ruiz in Colombia claimed 25,000 lives, underscoring the great hazard from lahars, which can be generated from the fifty-six, active, ice-capped Central and South American volcanoes during even very small eruptions. The probability of predicting the timing of such events is currently low, but the probability of a general prediction of volcanic eruption is high, giving sufficient time to install telemetered lahar alarm systems, which could largely avoid loss of life.--Modified abstract.
