Self-potential Data - Piton de la Fournaise caldera collapse

Here are the SP data recorded on the 27 and 30 March 2007 before the April 2007 caldera collapse at Piton de la Fournaise. The SP profile, 440m long, was installed before the collapse, between the rim of the Dolomieu crater and the Soufrière pit crater. The SP dynamic between the two reiterations displays two main anomalies. These anomalies are precisely correlated with the location of collapsed areas during the April 2007 Dolomieu caldera formation. These data are to be published in Volcanica Journal (Chaput et al., 2019).
