Measurement of seismometer orientation using the tangential P-wave receiver function based on harmonic decomposition

open access: yes, 2018
Accurate determination of the seismometer orientation is a prerequisite for seismic studies including, but not limited to seismic anisotropy. While borehole seismometers on land produce seismic waveform data somewhat free of human-induced noise, they ...

The First Instrumentally Detected Hydrothermal Explosion in Yellowstone National Park

open access: yesGeophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Hydrothermal explosions are one of the geological hazards most likely to impact people in Yellowstone National Park, but their frequency is poorly known. Infrasound and seismic sensors identified an explosion in Norris Geyser Basin on 15 April 2024, at 14:56 MDT (20:56 UTC)—the first instrumentally detected hydrothermal explosion in the ...

A study of some seismometers

open access: yesEos, Transactions American Geophysical Union, 1935
This paper discusses the advantages of seismometers that record displacement over instruments that measure velocity or acceleration. It shows that a portable seismometer using changes in capacitance between condenser‐plates to produce proportionate changes of current in an oscillograph has many good characteristics, chief of which are the ease and ...

Broadband FBG resonator seismometer: principle, key technique, self-noise, and seismic response analysis.

open access: yesOptics Express, 2018
A broadband optical fiber seismometer based on FBG resonator is proposed for earthquake monitoring. The principle and key technique, high-resolution ultralow-frequency wavelength interrogation by dual-laser swept frequency and beat frequency method, are ...

Video camera and seismic monitoring of water bulge explosion at Strokkur Geyser, Iceland

open access: yesVolcanica
Eruptions of volcanoes and geysers share many fundamental similarities: for example, they are manifestations of Earth’s geothermal energy, involving the pressure-driven expulsion of fluids from the Earth’s interior.

NASA’s InSight mission on Mars—first glimpses of the planet’s interior from seismology

open access: yesNature Communications, 2020
NASA’s InSight mission is the first lander to deploy a seismometer on a planetary body since more than 40 years. With a year of seismic data from Mars, new discoveries on Mars’ tectonics and interior structure are just emerging.
