From: The 2010 seismovolcanic crisis at Taal Volcano (Philippines)
Daily variations of different parameters between January 2008 and March 2011. Gray box corresponds to the 2010 seismovolcanic crisis. From top to bottom: Horizontal components of the electric field at DAK (S–N, E–W), ground temperature measured at 80 cm depth at DAK, Horizontal components of the electric field at MCL station (N–S, E–W), Ground temperature recorded at 80 cm depth at MCL, Total Magnetic field differences [DAK–MCE], [MCE–MUT], and [DAK–MUT], Daily number of earthquakes (PHIVOLCS document), and Daily rainfall at the local Buco Observatory. Rainfall above 50 mm is added to each plot for comparison with single parameters. Dashed lines correspond to the pre-crisis trends
