The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18th eruption marked the beginning of a period of eruptive activity that lasted through 1986. From October 1980 through October 1986, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most of the growth occurred when magma extruded onto the surface of the dome, forming short (650 to 1,300 feet), thick (65 to 130 feet) lava flows. This data release is a 1-meter resolution digital elevation model (DEM) and a corresponding hillshade raster derived from a previously unpublished 1:2,000 scale topographic contour...

Samples of the crater lake water were filtered in the field with a 0.45 micron filter. Subsequently, additional precipitates formed in the solute-rich samples (secondary precipitates) which were subsequently filtered in the lab with a 0.45 micron filter. Resulting residues were analyzed both in situ on the filter and after scraping. Samples were sputter coated with 10 nm Au, then imaged in a Tescan VEGA3 scanning electron microscope (SEM) equipped with an Oxford 150 mm2 X-MaxN large area energy dispersive spectrometer at the U.S. Geological Survey, Menlo Park, CA. Elemental backscatter (BSE) images were collected with an accelerating voltage (HV) of 30 kV and a working distance (WD) of ~15 mm. Magnification is indicated...

Samples of the crater lake water were filtered in the field with a 0.45 micron filter. Subsequently, additional precipitates formed in the solute-rich samples (secondary precipitates) which were subsequently filtered in the lab with a 0.45 micron filter. The mineralogy of secondary precipitates for samples HM19-01 and HM20-01A,B,C that were collected on 10/26/2019 and on 1/17/2020, respectively was determined by X-ray diffraction (XRD). Analysis was carried out at the British Natural History Museum with a Enraf-Nonius PDS120 diffractometer equipped with a primary Germanium (111) monochromator and an INEL 120° curved position sensitive detector (PSD). Data were collected from 7-120° 2θ using Co Kalpha1 radiation...

The San Juan Mountains in southwestern Colorado have long been recognized as a site of exceptionally voluminous mid-Tertiary volcanism, including at least 24 major ignimbrite sheets (each 150-5,000 km3) and associated caldera structures active at 33-23 Ma. More recent volcanologic and petrologic studies in the San Juan region have focused mainly on several ignimbrite-caldera systems: the southeastern area (Platoro complex), western calderas (Uncompahgre-Silverton-Lake City), the central cluster (La Garita-Creede calderas). The northeast San Juan region that was far less studied until recently occupies a transition between earlier volcanism in central Colorado and the larger-volume younger ignimbrite-caldera foci...

The 2018 lower East Rift Zone eruption of Kīlauea volcano, Island of Hawaiʻi, was one of the most destructive effusive eruptions worldwide in the past century, destroying over 700 structures (Neal and others, 2019; Meredith and others, 2022). Between May and September 2018, a total of 24 fissures opened, producing a lava flow field with an area of 36 km2. By the end of May, the eruption had focused at fissure 8, which produced the dominant lava flow of the eruption. This lava flow extended north from its vent in Leilani Estates and entered the ocean in Kapoho, reaching a total subaerial length of 13 km. This flow was active for about two months, from May 28 to August 4, followed by several weeks of weak vent...

Samples for water chemistry analysis were filtered to 0.45 µm upon collection. Since the solute-rich samples continued to form precipitates, samples were filtered again immediately prior to analysis if needed. All samples were very rich in solutes and were analyzed at multiple dilutions (1:100 to 1:1000) to match instrument measurement ranges for various analytes. Water chemistry analyses were performed at the U.S. Geological Survey laboratories in Menlo Park, California. The concentrations of fluoride (F-), chloride (Cl-), sulfate (SO42-), and bromide (Br-) in samples were determined by ion chromatography with a Dionex ICS-2000, using a 250 mm Dionex IonPac AS18 column. The concentrations of major cations...

Tiltmeter data from station Jonika Flow (JKA) used in the publication "Pre-existing ground cracks as lava flow pathways at Kīlauea in 2014" by Tim R. Orr, Edward W. Llewellin, Kyle R. Anderson, and Matthew R. Patrick. These data were collected in 2014 by Asta Miklius of the USGS Hawaiian Volcano Observatory.
The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. During 2017, U.S. Forest Service contracted the acquisitions of airborne lidar surveys of Mount St. Helens and upper North Fork Toutle River basin, part of a larger 2017-2018 survey of the Gifford Pinchot National Forest. The U.S. Geological Survey combined and reprojected 81 raster datasets, provided by the U.S. Forest Service in October 2018, into a single digital elevation model (DEM) of the ground surface, including beneath forest cover (that is, 'bare earth')....

Aliquots of collected water samples were prepared for isotopic analysis at the USGS laboratories in Menlo Park, CA by precipitating dissolved sulfate as barium sulfate, using the methods of Carmody and others (1997). Sulfur isotopes were analyzed at the USGS laboratories in Reston, Virginia. For sulfur isotope ratio measurements, dissolved sulfate is converted to BaSO4, which is analyzed by conversion to sulfur dioxide with an elemental analyzer and subsequent analysis with a continuous flow isotope ratio mass spectrometer (Brenna, 1997). Samples are analyzed simultaneously with BaSO4 isotopic reference materials. No correction for oxygen isotopic composition is made to the reported sulfur isotope data. For...

Samples of the crater lake water were filtered in the field with a 0.45 micron filter. Subsequently, additional precipitates formed in the solute-rich samples (secondary precipitates). The solids that accumulated on the filters (both secondary and original precipitate) were digested by heating overnight in a sealed Teflon vial with 300 µL concentrated HCl, 100 µL concentrated HNO3, and 500 µL concentrated HF. Following digestion, samples were dried down, then re-dissolved in 300 µL concentrated HNO3 and diluted with MilliQ water. The liquid from the digested samples were analyzed for element concentrations by inductively coupled plasma-optical emission spectrometry (ICP-OES) using a ThermoFisher ICAP 6500 Duo at...
