a Schematic showing locations of proposed sources for Phase 1 and Phase 2 under Taal Volcano and the location of tiltmeter DAK. Leveling lines performed by PHIVOLCS are shown as black dashed lines. b Calculated tilt at DAK during Phase 1 (April to June 11, 2010, Phase 1 in Fig. 8) from an inflation source at a depth of 5 km. The surface projection of this source is 1 km to the east of DAK. See text for source details. c Calculated tilt at DAK during Phase 2 (June 11 to July 13, 2010, Phase 2 in Fig. 8) from an inflation source at a depth of 2.5 km. The surface projection of this source is 1 km to the south of DAK under the MCL. See text for source details
