A Seismometer for Observations on Mars

Cosmic Research, 2021
Thos article paper the results of the development and creation of a three-component seismometer for measurements on Mars. In the low-frequency and quasi-static region of the spectrum, the instrument also performs the functions of a tiltmeter and gravimeter. A description of the sensing element, a single-axis sensor, is given.

Fiber-Optic Seismometer

SPIE Proceedings, 1987
This paper reviews the present state of seismometry and discusses a seismometer based on fiber-optic technology. In addition, some actual data taken by a portable laboratory-grade fiber-optic seismometer is presented.

Portable digital seismometer [PDF]

Seismic Instruments, 2011
We have developed an autonomous portable digital seismometer for measurements in the field, in engineering constructions, and in hard-to-reach places. The seismometer is a monoblock including an SM-6 seismic receiver and digital seismic recorder. The SM-6 seismic receiver is a highly effective device for field work on investigating a microseismic wave ...

BlueSeis3A: Full Characterization of a 3C Broadband Rotational Seismometer

, 2018
Recently, due to observations of rotational ground motions, a promising new field of research in seismology and engineering has developed. However, exploration of rotation's potential has been hampered by the lack of a portable, reliable, and highly ...

Single seismometer structure

Science, 2021
Planetary Science Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al. , Knapmeyer-Endrun et al. , and Stahler et al. used recently detected marsquakes from the seismometer deployed during the InSight mission to map the interior of Mars (see the Perspective by Cottaar and Koelemeijer).

The Electrochemical Seismometer Based on a Novel Designed Sensing Electrode for Undersea Exploration

2019 20th International Conference on Solid-State Sensors, Actuators and Microsystems & Eurosensors XXXIII (TRANSDUCERS & EUROSENSORS XXXIII), 2019
This paper developed a MEMS based electrochemical seismometer featured with a new structure of sensing electrodes. The sensing electrodes in this study can significantly increase the working areas of cathodes, and accurately control the geometries of the

A 3D Broadband Seismometer Array Experiment at the Homestake Mine

Seismological Research Letters, 2018
Seismometer deployments are often confined to near the Earth’s surface for practical reasons, despite the clear advantages of deeper seismometer installations related to lower noise levels and more homogeneous conditions. Here, we describe a 3D broadband

An electrostatic seismometer*

Bulletin of the Seismological Society of America, 1948
Abstract Theory and description are given of sensitive capacity-type seismometers having small size, eddy-current damping, and an undamped period of 0.23 second. The voltage output is taken to the grid of a cathode-follower tube within the instrument and is thereafter amplified.

Ocean‐Bottom Seismometer Instrument Orientations via Automated Rayleigh‐Wave Arrival‐Angle Measurements

, 2017
After more than 10 years of the U.S. ocean‐bottom seismometer (OBS) Instrument Pool operations, there is still need for a consistent and accurate procedure to determine the orientation of the horizontal seismometer components of passive‐source free‐fall ...
