FDSN code Y5 (2021-2021) Network name Valles Caldera and Gallina Fault Node Array 2021 (Valles Nodes 2021)
Start year 2021 Operated by
  • University of New Mexico
End year 2021 Deployment region -
Description

The deployment is an add-on to an NSF project on imaging and seismicity detection around Valles Caldera. The new node data would help 3-D imaging coverage and target the mid-crustal structures hosting earthquakes near the surface position of the Gallina Fault northwest of the caldera. A rare, for New Mexico, M4.2 earthquake occurred near the Gallina Fault in July and no publicly accessible seismometers are within 100 km so very little is known about the structure hosting the earthquake sequence and even the locations may not be well constrained. The proposed network would have very low magnitude detection capabilities (~M-1) so that active structures are likely to be observed within 1 month.
