********************************** Recent enhanced activity triggers changes in risk perception: Turrialba Volcano, Costa Rica. April 10, 2007. From: Eliecer Duarte <eduarte@xxxxxxxxx> ********************************** Despite monthly reports of activity, at least 2 extraordinary field reports, and abundant information on our web page (http://www.ovsicori.una.ac.cr ) about rapid changes, misperceptions persist in communities around this volcano and other audiences. Within these recent 2 weeks, a growing number of phone calls from government officials, journalists and general public keep us busy. Due to clear visibility, changes in wind patterns, and heavy visitation to the summit area; rumors, reports and concerns multiply. Rapid changes in Turrialba`s activity include: growth of fumarolic field, heating of new areas within and outside the crater area, burning of vegetation and enrichment of gases. A new seismic station was installed in the crater area and is currently providing valuable information to OVSICORI`s monitoring group.
