Microelectromechanical system gravimeters as a new tool for gravity imaging [PDF]

open access: yes, 2018
A microelectromechanical system (MEMS) gravimeter has been manufactured with a sensitivity of 40 ppb in an integration time of 1 s. This sensor has been used to measure the Earth tides: the elastic deformation of the globe due to tidal forces.

Use of Local Seismic Network in Analysis of Volcano-Tectonic (VT) Events Preceding the 2017 Agung Volcano Eruption (Bali, Indonesia)

open access: yesFrontiers in Earth Science, 2021
This study provides an attempt to analyze the pre-eruptive seismicity events for volcano eruption forecasting. After more than 50 years of slumber, Agung volcano on Bali Island erupted explosively, starting on November 21, 2017. The eruption was preceded

The 2001 Taupō Fault Belt Seismicity as Evidence of Magma‐Tectonic Interaction at Taupō Volcano

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The Taupō Volcanic Zone (TVZ) is the southern extent of the Tonga‐Kermadec volcanic arc and encompasses the Taupō Rift, with the two structures accommodating extension through the central North Island of New Zealand via magmatic and tectonic processes,

On heterogeneities with reduced viscosity in the mantle under the Kamchatka volcanoes according to seismological data [PDF]

open access: yesBulletin Volcanologique, 1973
A seismological study of the upper mantle under the Kamchatka volcanoes using body waves from nearby earthquakes has shown local heterogencities consisting of materials with reduced elastic properties at depths from 30 to 90 km.

Deep Long‐Period Earthquakes at Akutan Volcano From 2005 to 2017 Better Track Magma Influxes Compared to Volcano‐Tectonic Earthquakes

open access: yesGeophysical Research Letters, 2023
Both volcano‐tectonic (VTs) and deep long‐period earthquakes (DLPs) have been documented at Akutan Volcano, Alaska and may reflect different active processes helpful for eruption forecasting. In this study, we perform high‐resolution earthquake detection,
