Investigating potential icequakes at Llaima volcano, Chile

Abstract: Glacially- and magmatically-derived seismic events have been noted to heavily overlap in characteristics, thus there exists the potential for false-alarms or missed warnings at ice-covered volcanoes. Here we present the first study to specifically target icequakes at an ice-covered volcano in Southern Chile. Two months of broadband seismic data collected at Llaima volcano in 2015 were analyzed in order to quantify, characterize, and locate glacially-derived seismic events at one of the most active ice-covered … Show more

“…Since no labels are predicted, UML results can be difficult to interpret physically, and since there is no defined target, not all clusters or features may be of scientific interest. Despite these challenges, numerous seismic studies have produced insight through unsupervised feature‐extraction, clustering, or a combination of the two (e.g., Chamarczuk et al., 2019; Sick et al., 2015; Steinmann et al., 2021; Trugman & Shearer, 2017; Yoon et al., 2015), including in numerous glaciated, volcanic and/or geothermal settings (e.g., Holtzman et al., 2018; Jenkins et al., 2021; Lamb et al., 2020; Ren et al., 2020; Seydoux et al., 2020). Seydoux et al.…”
