EarthScope: An Earth Science Program

The EarthScope facilities maintain ~100 Campaign GPS systems and ~2100 broadband and short-period FlexArray seismic sensors. The Campaign/Flexible instruments allow for focused observation and study of key geophysical locales and are available to the scientific community through proposals approved by the NSF. For information about GPS campaign instruments go to UNAVCO. For information about past and present FlexArray seismic instrument deployments and schedules go to IRIS. For images from the field and a photo-based station installation guide for FlexArray sites visit FlexArray Gallery.

SIEDCAR

SIEDCAR (Seismic Investigation of Edge-Driven Convection Associated with the Rio Grande Rift) investigators have installed a two-dimensional array of 75 broadband seismic stations along the eastern edge of the Rio Grande Rift in New Mexcio and Texas. For more information: Siedcar.

BIGHORN

The BIGHORNS project is an integrated geological and geophysical investigation of contractional basement-involved foreland arches. The active-passive seismic experiment is conducted across the Rocky Mountain Bighorn Arch of Wyoming and Montana. For more information: Bighorns.

ARRAY OF ARRAYS

The Array of Arrays project on the Olympic Peninsula, Washington, consists of a set of seismic arrays to study tremor and low-frequency earthquakes with unprecedented resolution in an active and relatively predictable portion of the Cascadia subduction zone. For more information: Array of Arrays.

RIO GRANDE GPS

The RIO GRANDE RIFT experiment consists of a multi-year deployment of 26 campaign GPS instruments in Colorado and New Mexico to measure crustal deformation and stretching in the Rio Grande Rift. For more information: Rio Grande Rift.

FACES

FACES, the Flexarray Along Cascadia Experiment for Segmentation, is a deployment of 20+ broadband seismic sensors in western Oregon and Washington with the goal of resolving structural controls on episodic tremor and slip all along Cascadia. For more information: Faces.

COLZA

COLZA, the Central Oregon Locked Zone Array, is an amphibious array of 16 ocean bottom seismometers (2007-2009) and 6 onshore FlexArray stations to better constrain seismicity of the central Oregon part of the Cascadia subduction zone. For more information: Colza.

CAF�

CAFE, Cascadia Arrays For EarthScope, seismologists deployed a network of 60 seismometers that covered much of western Washington to study how the Cascadia subduction system works. For more information: Cafe.

MENDO

The Mendocino Experiment (2007-2009) used a dense array of broadband seismographs to investigate the structure of the Mendocino Triple Junction, the northernmost terminus of the San Andreas Fault. For more information: Mendocino.

SNEP

SNEP, the Sierra Nevada EarthScope Project, (2005-2007) deployed seismic stations in California and Nevada to image foundering lithosphere beneath the Sierra Nevada Mountains. For more information: SNEP.
