Here we present a project, funded under the auspices of Geoscientists Without Borders, that focuses on the currently erupting Santa Maria and Santiaguito volcanic complex. Santa Maria is one of 16 international decade volcanoes, which were designated as areas of special interest by the International Association of Volcanology and Chemistry of the Earth's Interior because of their history and potential to generate destructive eruptions, and their proximity to densely populated areas. The 1902 eruption of Santa Maria claimed the lives of about 8,700 people and many more died from a consequent outbreak of malaria. In 1922 the ongoing eruption of Santiaguito began with the growth of a lava dome complex inside the crater of the 1902 eruption. Since then, Santiaguito has produced, for nearly a century, explosions, collapses and avalanches, pyroclastic flows and lahars, which are a constant threat to a population of several tens of thousands, and to farming developments in the area. Villages and infrastructure around Santa Maria and Santiaguito have sustained severe damage from pyroclastic flows and lahars in the recent past, including the notable example of the town of El Palmar located about 10km from Santiaguito, which was destroyed twice by lahars, and subsequently abandoned, forcing the displacement of local population to a new settlement. Until very recently, surveillance at Santiaguito was limited to visual observations and manual analyses of data from a sparse seismic network. The overarching goal of this project is to assist the Instituto Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH) with improving monitoring at Santaguito through the installation of state-of-the-art geophysical equipment, and by providing training in modern volcano monitoring technology to local personnel. Here, we present our project and the details of the installation of new realtime, broadband seismo-acoustic stations in the area.Presentation Date: Monday, September 16, 2019Session Start Time: 1:50 PMPresentation Start Time: 3:05 PMLocation: 303BPresentation Type: OralKeywords: monitoring, sensors, volcanicsPermalink: https://doi.org/10.1190/segam2019-3215154.1FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2019ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2019 Pages: 5407 publication data© 2019 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 01 Aug 2019 CITATION INFORMATION Silvio De Angelis, Andreas Rietbrock, Yan Lavallee, William Carter, Paul Wallace, Ellen Gottschämmer, and Alicia Rohnacher, (2019), "An international partnership to develop volcano monitoring capacities in Guatemala," SEG Technical Program Expanded Abstracts : 4782-4785. https://doi.org/10.1190/segam2019-3215154.1 Plain-Language Summary KeywordsmonitoringsensorsvolcanicsPDF DownloadLoading ...
