8Y (2021-2023): GEODES Kilbourned Hole Active Source Seismic Experiment

• University of Maryland (UMD), United States of America

We are studying the near surface structure of the maar eruption deposits in the Potrillo Volcanic Field, New Mexico using active source seismology. The field site is located near Kilbourne Hole and Hunt's Hole maar volcanos, and the project has the goal of determining the thickness and subsurface variation in the ash and surge deposits found around the rim of the craters. Eruption material volumes are essential for understanding the volatile budget and evolution of the eruption sequence. The project builds upon past exploration activities by NASA at Kilbourne Hole, and the active source seismology will also be used to understand how similar investigations can be conducted on the Moon and Mars. We are testing the resolution of traditional geophone lines against 3 component nodal investigations (provided separately by the NASA project). The data will be made available to the public through the Planetary Analogs Website at USGS and at the IRIS DMC.
