2011-2020: A Decade of global volcanic events observations at the IMS Infrasound network

The Global Volcanism Program (GVP) includes a comprehensive list of the 1281 Earth’s active volcanoes and their eruptions over the last 12,000 years. In this work, we used the web-based GVP database of the Smithsonian Institute to correlate detections in the period 2011–2020. According to GVP data, 360 eruptions (or confirmed eruptive activity) occurred on 138 volcanoes around the world. Among those, we selected 67 confirmed eruptions originated from 46 volcanoes, with Volcanic Explosive Index (VEI) above 3. Data from 43 IMS infrasound stations were processed and analysed in the specified time window using the Progressive Multi-Channel Correlation (PMCC) algorithm. A station-to-source back-azimuth deviation of 5° was considered, using a cross-bearing azimuth methodology. The IMS network infrasound detections of the 67 selected volcanic events are presented, as well as the correspondence of the volcanic events with the lists of in the Late Event Bulletin (LEB, 52 events), Standard Event Lists (SEL3, 13 events) and Reviewed Event Bulletin (REB, 30 events) produced by the CTBTO International Data Centre (IDC).
