The following map showing the location of the long baseline titmeter at Mammoth Lakes is taken from Clark et al 1982.The distances of the three vaults from the mapped fault are 145 m (A), 495 m (B) and 220 m (C). The inferred position of the subsurface magma chamber is 8.2 km N58W of the tiltmeter.
