Volcán Turrialba caused its neighbors to sit up and take notice again Monday night. The volcano erupted again and sent wind-born ash as far west as Desamparados and Tres Ríos. That was at 9:24 p.m., and emergency officials know for sure because the mountain is being monitored closely.
Staffers from the Red Sismológica Nacional at the Universidad de Costa Rica, the Observatorio Vulcanológico y Sismológico at Universidad Nacional and emergency commissions were collecting data and evidence of the ash in the vicinity Tuesday.
The national park that surrounds the mountain continues to be closed, and an alert is posted for the cantons of Turrialba and Alvarado. The area is east of San José.
The Comisión Nacional de Prevención de Riesgos y Atención de Emergencias has an evacuation plan posted. Residents continue to live near the mountain. Many are dairy farmers who graze their herds on the flanks of the mountain. The animals are the ones most affected by the ash.
Cattle sometimes spend the day with their backs covered with the fine, gritty material.
Scientists study the ash to determine its composition. Ash that has come from magma deep inside the volcano portends more eruptions. Reports on the latest eruption will be made known later in the week.
