This data release provides quantitative whole rock geochemical results from The Geysers vapor-dominated geothermal field in California. The concentrations of major elements are reported in oxide weight percent by wavelength dispersive x-ray fluorescence (WDXRF), the concentrations for sixty elements are reported in elemental weight percent (pct) or parts per million (ppm) from inductively coupled plasma-optical emission spectrometry-mass spectrometry ICP-OES-MS analysis, mercury is reported in ppm by cold vapor atomic absorption spectrometry (CVAAS), and ammonium in ppm from automated colorimetry analysis. The analyses show significant enrichment of volatile elements and elements such as sulfur, boron, arsenic,...

This data release provides semiquantitative mineralogy results from X-ray diffraction (XRD) analyses of mineral scales from The Geysers vapor-dominated geothermal field in California. The mineral species and their abundances are reported in weight percent and values have been normalized to total 100 percent for each sample. The X-ray diffraction results show that the mineral samples from the wellheads are primarily composed of ammonium (NH4+) sulfate minerals and sassolite B(OH)3, whereas sulfide minerals such as cinnabar and pyrite are the most abundant minerals observed in the power plants. Mineral scales vary along the steam flow path, from the wellhead to power plants. Relatively abundant iron oxide and iron...

Provided here is a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. This dataset contains more than 23,908earthquakes in 346 well distributed clusters. Currently there are more than 4M arrival times with the majority being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully processed...

The Uwajima cluster is named for the city of Uwajima on the southwest coast of the island of Shikoku, Japan. The seismicity is mainly beneath the Bungo Channel separating Shikoku and Kyushu. The cluster was motivated by a 6.3 Mw earthquake on April 17, 2024, and contains two other magnitude 6.3 events, on August 5, 1968 and January 21, 2022. The seismicity is at depths of 25-70 km, associated with the subduction zone. All events are observed to teleseismic distances. Station coverage is superb and all events have depth constraint from near-source readings. Most events also have depth estimates from teleseismic depth phases that are in close agreement. ...
River shown in panoramic images 568 and 569. Shown as it disappears in cavern. Aguadilla or Arecibo County, Puerto Rico. February 1922.

The Seattle cluster is named for Seattle, Washington, U.S.A., a city considered to be at considerable risk from a great earthquake on the Cascadia subduction zone. The seismicity in the cluster occurs in two depth ranges, in the crust from ~5-30 km and on the slab interface at depths of 45-65 km. The cluster includes the 6.5 Ms earthquake on April 29, 1965 and the 6.6 Ms earthquake on February 28, 2001, both on the slab interface, and several magnitude 5.0-5.2 events in the crust. Station coverage in the area is exceptional, making epicentral location calibration very robust, but depth resolution is complicated by an exceptional degree of velocity heterogeneity beneath Puget Sound, where shear wave velocities are...
