Imaging the Laguna del Maule Volcanic Field, central Chile using magnetotellurics: Evidence for crustal melt regions laterally-offset from surface vents and lava flows

- A 3-D array of MT data was collected at Laguna del Maule Volcanic Field (LdMVF).
- 3-D inversion created the first complete images of the geoelectric structure.
- One conductive body beneath the LdMVF is interpreted as a hydrothermal zone.
- Two magma bodies are imaged to the north and northwest of the lake.
- Results suggest a lateral component as material moves from depth to existing vents.
