[Show abstract][Hide abstract] ABSTRACT:
We report data from a radon survey conducted at Villarrica volcano.
Measurements have been obtained at selected sites by
E-PERM® electrets and two automatic stations utilizing
DOSEman detectors (SARAD Gmbh). Mean values for Villarrica are 1600
(±1150) Bq/m3 are similar to values recorded at
Cerro Negro and Arenal in Central America. Moderately higher emissions,
at measurement sites, were recorded on the NNW sector of the volcano and
the summit, ranging from 1800 to 2400 Bq/m3. These
measurements indicate that this area could potentially be a zone of
flank weakness. In addition, the highest radon activities, up to
4600 Bq/m3, were measured at a station located near the
intersection of the Liquiñe-Ofqui Fault Zone with the Gastre
