The Owens Valley, a long, narrow valley along the east side of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports the water more than miles south to areas of. Long Valley caldera, in east-central California, has been the site of research on both geothermal resources and volcanic hazard mitigation over the past 30 years (Fig. 1, Fig. 2).Recent reports describe the history and present state of volcanic unrest in this region (e.g. Miller, , Hill et al., ), and numerous papers describe the present-day hydrothermal system and its utilization for Cited by:

Hydrologic and geochemical monitoring of surface and subsurface features began in July to determine if changes were occurring in response to processes causing earthquakes and crustal deformation. Differences since in fluid chemistry of springs has been.
The U.S. Geological Survey continued to monitor hydrologic and geochemical conditions in the Long Valley caldera during The monitoring is directed toward detecting changes in the hydrologic system caused by tectonic or magmatic processes.
Data collected during include chemical and isotopic composition of water from selected streams sites, springs, and wells; pumpage from four. Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth valley is one of the Earth's largest calderas, measuring about 20 miles (32 km) long (east-west), 11 miles (18 km) wide (north-south), and up to 3, feet ( m) deep.
Long Valley was formedyears ago when a very large eruption released very hot ash that later cooled to form the Bishop Location: Mono County, California, United States. The Long Valley Hydrologic Advisory Committee (LVHAC), formed inreviews hydrological data and makes non-binding suggestions for monitoring and project conditions meant to protect the thermal and non-thermal hydrologic resources of the Long Valley Caldera.
Long Valley Caldera hosts a large hydrothermal system, with hot groundwater, boiling springs, and hydrothermal system is recharged with water primarily from snow-melt in the Sierra Nevada highlands along the western rim of the water infiltrates to depths of a few kilometers where it is heated to at least °C ( °F) by hot rock near geologically young.
Long Valley caldera and the Mono–Inyo volcanic chain of eastern California (Fig. 1, Fig. 2, Fig. 3) form one of several geologically youthful volcanic systems in gh these areas pose potential hazards to population centers from future volcanic eruptions (Miller, ), they also provide an abundance of recreational opportunities, spectacular scenery, natural thermal phenomena Cited by: Gas monitoring can either be conducted close to the source in ground-based campaigns or from a distance using remote sensing.
