The Journal of the Geological Society of Japan, 2020 Kusatsu-Shirane Volcano is one of the most active volcanoes in Japan. The summit of the volcano comprises three young pyroclastic cones: the Motoshirane Pyroclastic Cone Group (MPCG), which erupted on January 23 , 2018 , with almost no eruptive ...

Earth, Planets and Space, 2020 Coeruptive deformation helps to interpret physical processes associated with volcanic eruptions. Because phreatic eruptions cause small, localized coeruptive deformation, we sometimes fail to identify plausible deformation signals.

Frontiers in Earth Science, 2022 Regular sampling of lake water has been performed at many volcanoes to assess the state of volcanic activity. However, it is not clear whether the absolute concentrations or, instead, rate of changes in concentrations are more suitable for such ...

Source Mechanism of Small Long-Period Events at Mount St. Helens in July 2005 Using Template Matching, Phase-Weighted Stacking, and Full-Waveform Inversion [PDF]
, 2015 Long-period (LP, 0.5-5 Hz) seismicity, observed at volcanoes worldwide, is a recognized signature of unrest and eruption. Cyclic LP “drumbeating” was the characteristic seismicity accompanying the sustained dome-building phase of the 2004–2008 eruption ...

Provenance of Lower Cretaceous sediments in the Nariwa and Hokubo areas, Okayama Prefecture, deduced from detrital modes and geochemistry of sandstones [PDF]
, 1996 Petrographic and geochemical study of sandstones from the Kenseki Formation have shown that the sandstones are compositionally immature. The immaturity is reflected geochemically by their low SiO2 contents (52-66 wt%) and petrographically by low modal ...

Geothermal and Mineralogic Analysis of Hot Springs in the Puracé‐La Mina Sector in Cauca, Colombia
Geofluids, Volume 2019, Issue 1, 2019., 2019 Thermal waters are natural resources of great value to geothermal sciences, the tourism industry, and health. In this work, geochemical classification of physicochemical results of 17 sources at the Puracé‐La Mina (Cauca, Colombia) sector was implemented in order to strengthen and determine their potential applications and enhance the continental ...
