Linking the flow-induced tremor model to the seismological observation: application to the deep harmonic tremor at Hakone volcano, Japan

Earth, Planets and Space, 2023
Decades ago, Julian (J Volcanol Geotherm Res 101:19–26, 1994. https://doi.org/10.1029/93JB03129 ) proposed the lumped parameter model of non-linear excitation of an elastic channel vibration by fluid flow as a mechanism of volcanic harmonic tremor. Since

pH Threshold Impacts Chalcopyrite Bioleaching Dynamics for the Extreme Thermoacidophile Sulfurisphaera ohwakuensis. [PDF]

Biotechnol Bioeng
Chalcopyrite bioleaching by the extreme thermoacidophile, Sulfurisphaera ohwakuensis. ABSTRACT The extremely thermoacidophilic archaeon Sulfurisphaera ohwakuensis served as the basis for probing how initial pH (pHinitial) affects copper mobilization from chalcopyrite. Screening of small‐scale cultures (75 mL) at 75°C revealed that ~pH 3.0 was a maximal

Analysis and experimental investigation of Apollo sample 12032,366‐18, a chemically evolved basalt from the Moon

Meteoritics &Planetary Science, Volume 57, Issue 4, Page 794-816, April 2022., 2022
Abstract Sample 12032,366‐18 is a 41.2 mg basaltic rock fragment collected during the Apollo 12 mission to the Moon. It is enriched in incompatible trace elements (e.g., 7 ppm Th), but does not have a bulk composition that would be considered a KREEP (enriched in potassium, rare earth elements, and phosphorous) basalt.

Volcano‐Tectonic Setting of the Pisciarelli Fumarole Field, Campi Flegrei Caldera, Southern Italy: Insights Into Fluid Circulation Patterns and Hazard Scenarios

Tectonics, Volume 40, Issue 5, May 2021., 2021
Abstract Phreatic and hydrothermal eruptions are small energetic explosive events that generally have few to no precursors and represent a considerable hazard in tourist and urban areas. At the Campi Flegrei caldera, these events have occurred at the Solfatara volcano and have likely occurred at the nearby Pisciarelli site, where the most powerful ...

Resistivity characterisation of Hakone volcano, Central Japan, by three-dimensional magnetotelluric inversion

Earth, Planets and Space, 2018
On 29 June 2015, a small phreatic eruption occurred at Hakone volcano, Central Japan, forming several vents in the Owakudani geothermal area on the northern slope of the central cones.

Combining Petrology and Seismology to Unravel the Plumbing System of a Typical Arc Volcano: An Example From Marapi, West Sumatra, Indonesia

Geochemistry, Geophysics, Geosystems, Volume 22, Issue 4, April 2021., 2021
Abstract Marapi in Sumatra is characterized by frequent short‐lived explosions and small eruptions (Volcanic Explosivity Index 1–2) and in the past 250 years, the volcano has erupted >60 times. Recent volcanic bombs and the presence of broadband seismic stations lead us to reconstruct the plumbing system of the volcano through an interdisciplinary ...

Monitoring ground deformation of eruption center by ground-based interferometric synthetic aperture radar (GB-InSAR): a case study during the 2015 phreatic eruption of Hakone volcano

Earth, Planets and Space, 2018
We successfully monitored the ground deformation of an eruption center during the 2015 phreatic eruption of Hakone volcano, Japan, using ground-based interferometric synthetic aperture radar (GB-InSAR).

Volcanic unrest at Hakone volcano after the 2015 phreatic eruption: reactivation of a ruptured hydrothermal system?

Earth, Planets and Space, 2021
Since the beginning of the twenty-first century, volcanic unrest has occurred every 2–5 years at Hakone volcano. After the 2015 eruption, unrest activity changed significantly in terms of seismicity and geochemistry. Like the pre- and co-eruptive unrest,
