The Global Volcanism Program is not aware of any Holocene eruptions from Santa Clara. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Santa Clara page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
There is no Deformation History data available for Santa Clara.
There is no Emissions History data available for Santa Clara.
Reddish scoria caps the circular rim of the southernmost of two cinder cones in the lower Diamond Valley of SW Utah. The northern cone in the middle distance is surrounded by a basaltic lava field. Light-colored rocks of the Navajo Sandstone at the left lie across a narrow gap from the southern cone; lava flows from the two cones spilled through this gap into Snow Canyon. The Pine Mountains rising in the distance are in part covered by older lava flows in the St. George basin.
Two cinder cones in the Diamond Valley of SW Utah were the sources of the voluminous Santa Clara lava flow, one of the youngest in Utah. The symmetrical southern cone, capped by a pristine crater, is seen here from the flanks of the northern cone. Lava flows from the two cones filled the lower Diamond Valley in the foreground and then spilled through a narrow gap to the right of the southern cone into Snow Canyon.
The Santa Clara lava flow fills the valley of Snow Canyon, cut in colorful rocks of the Navajo Sandstone. The young flow, covered only by scrubby vegetation, split into several lobes and flowed around several peninsulas and islands of the reddish Navajo Sandstone that protrude through the black basalt. The flow traveled through the narrow gap at the upper left and reached nearly to the Santa Clara River, 16 km from the source of the flow.
The dark-colored Santa Clara lava flow cutting diagonally across the photo to the left poured over cliffs of the Navajo Sandstone in lava cascades up to 120 m high. Several lava cascades occurred around sandstone islands in Snow Canyon State Park. The colorful Navajo cliffs display a transition between underlying reddish oxidized and overlying whitish unoxidized rocks.
The sparsely vegetated Santa Clara lava flow traveled 16 km to the south down Snow Canyon, cut through the colorful red and white rocks of the Navajo Sandstone formation. The flow, originating from two youthful cinder cones in Diamond Valley above Snow Canyon, was produced during one of the youngest eruptions in the Colorado Plateau/Basin and Range region. This Pliocene-to-Quaternary volcanic field north of St. George in SW Utah contains numerous basaltic cinder cones and lava flows. 
The Santa Clara lava flow in SW Utah split into several lobes and diverted around two islands (kipukas) of colorful cross-bedded Navajo Sandstone. Note the person standing on the left kipuka for scale. The largest kipuka of the Santa Clara flow is about 1 km in length.
The Santa Clara lava flow exited the narrow Snow Canyon cut in cliff-forming rocks of the Navajo Sandstone in the background. When the basaltic lava flow reached the flat-lying valley of the Santa Clara River cut in less resistant shales of the Chinle formation, it spread out laterally, reaching a width of more than 1.5 km. The flow, one of the youngest in Utah, traveled a distance of 16 km from its source in the Diamond Valley. Housing developments near St. George, Utah now encroach on its distal margins.Maps are not currently available due to technical issues.

WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
| IRIS seismic stations/networks | Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Santa Clara. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |
| UNAVCO GPS/GNSS stations | Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Santa Clara. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
