The ash from Turrialba volcano has accompanied the Central Valley for a ‘long time’.
Alvarado Induni, volcanologist at the National Seismological Network (RSN), analyzed the historical reality of the volcano in an article published on the University of Costa Rica (UCR) website.
The expert referred to Turrialba’s volcanic activity from 1963 to 1965, when it had a similar behavior to recent years.
Incidentally, Alvarado explained that it is not possible that rockfalls take place. In addition, he repeated that lava flows cannot reach the Central Valley.
The volcano has had three consecutive, eruptive-activity days and, as explained by volcanologist Mauricio Mora, the quantity of emanated materials is related to the internal characteristics of the volcano.
The conduit has deepened and widened as part of the normal evolution of an eruptive cycle to another. As consequence, more material is projected into the atmosphere,
explained the expert.
Ash fall has taken place in the last few hours in sectors such as Moravia, Coronado, Goicoechea and the province of Heredia, the cantons of San Isidro, San Rafael, Barva, Jiménez Pococí, Silvia, La Picada and San Gerardo de Irazú.
