Researchers use electrical resistivity to find the heat source and reservoir feeding Long Valley Caldera's labyrinthine hydrothermal system.

Now, Peacock et al. have used magnetotellurics to create a three-dimensional (3-D) model of the ground down to 10 kilometers underneath the Long Valley volcanic system. To create this 3-D model, the team measured the Earth’s electrical response to natural magnetic fields at 61 stations across Long Valley Caldera.
