FDSN code 8G (2018-2019) Network name Investigating Geophysical Unrest at Sierra Negra (IGUANA)
Start year 2018 Operated by
End year 2019 Deployment region Ecuador, Galapagos
Short description

The Investigating Geophysical Unrest at Sierra NegrA (IGUANA) experiment was designed to monitor seismic activity associated with magmatic unrest at Sierra Negra volcano, Galapagos Islands, Ecuador. In late 2017, it was apparent that Sierra Negra was likely approaching a new eruption, and that the volcanic edifice was critically stressed. The experiment captured seismic broadband data during the final approach to eruption, the eruption onset on 26 June 2018, and co-eruptive deflation.
