Active platform stabilization with a 6D seismometer.

Publication Type: Academic Journal

Source(s): Applied Physics Letters. 10/24/2022, Vol. 121 Issue 17, p1-6. 6p.

Abstract: We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of freedom of the platform and does not require any additional sensors for...

The Seismicity of Mars Observed by the NASA InSight Mission.

Publication Type: Academic Journal

Source(s): European Review. Oct2022, Vol. 30 Issue 5, p639-656. 18p.

Abstract: This Plenary Lecture summarizes the seismicity of Mars recorded by the NASA InSight mission, which landed on Elysium Planitia on 26 August 2018. Equipped with a highly sensitive seismometer, the lander has been successfully recording the seismicity of ...

Measuring the phase response of a seismometer using superimposed sine signals.

Publication Type: Academic Journal

Source(s): Journal of Seismology. Oct2022, Vol. 26 Issue 5, p935-947. 13p.

Abstract: The sine calibration can be used for measuring the phase response of a seismometer. However, it has two shortcomings: (1) Transient responses that cannot be used for data processing appear multiple times. This increases the time consumption of the cali...

Site-specific variations in air-to-ground coupled seismic arrivals from the 2012 October 16 explosion at Camp Minden, Louisiana, United States.

Publication Type: Academic Journal

Source(s): Geophysical Journal International. Oct2022, Vol. 231 Issue 1, p243-255. 13p.

Abstract: Air-to-ground coupled seismic arrivals, resulting from infrasound interacting with the ground surface, can be identified on seismometers co-located with microbarometers. Dense networks of co-located sensors provide detailed spatial information about th...

Sub‐Lithospheric Small‐Scale Convection Tomographically Imaged Beneath the Pacific Plate.

Publication Type: Academic Journal

Source(s): Geophysical Research Letters. 9/28/2022, Vol. 49 Issue 18, p1-10. 10p.

Abstract: Small‐scale convection beneath the oceanic plates has been invoked to explain off‐axis nonplume volcanism, departure from simple seafloor depth‐age relationships, and intraplate gravity lineations. We deployed 30 broadband ocean bottom seismometer stat...

Optomechanical Accelerometers for Geodesy.

Publication Type: Academic Journal

Source(s): Remote Sensing. Sep2022, Vol. 14 Issue 17, p4389. 19p.

Abstract: We present a novel optomechanical inertial sensor for low-frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.715 (1) Hz, a mechanical quality factor of 4.76(3) × 105, a test mass of 2.6 g, and ...

Performance of a Rotational Sensor to Decipher Volcano Seismic Signals on Etna, Italy.

Publication Type: Academic Journal

Source(s): Journal of Geophysical Research. Solid Earth. Jun2022, Vol. 127 Issue 6, p1-22. 22p.

Abstract: Volcano‐seismic signals such as long‐period events and tremor are important indicators for volcanic activity and unrest. However, their wavefield is complex and characterization and location using traditional seismological instrumentation is often diff...

Development and Testing of a 5G Multichannel Intelligent Seismograph Based on Raspberry Pi.

Publication Type: Academic Journal

Source(s): Sensors (14248220). Jun2022, Vol. 22 Issue 11, p4193-4193. 14p.

Abstract: A seismograph was designed based on Raspberry Pi. Although comprising 8 channels, the seismograph can be expanded to 16, 24, or 32 channels by using a USB interfacing with a microcontroller. In addition, by clustering more than one Raspberry Pi, the nu...

Measurement of seismometer misorientation based on P-wave polarization: application to dense temporary broadband seismic array in the epicentral region of 2016 Gyeongju earthquake, South Korea.

Publication Type: Academic Journal

Source(s): Geosciences Journal. Jun2022, Vol. 26 Issue 3, p385-397. 13p.

Abstract: In this study, we probe the misalignment of 200 temporary broadband seismometers based on the polarization of P waves from regional and teleseismic earthquakes. The seismometers were deployed in the epicentral region of 2016 ML 5.8 Gyeongju earthquake,...

Ocean-Bottom Laser Seismograph.

Publication Type: Academic Journal

Source(s): Sensors (14248220). Apr2022, Vol. 22 Issue 7, p2527. 16p.

Abstract: This paper describes an ocean-bottom laser seismograph, based on the modified laser meter of hydrosphere pressure variations, and designed to record vertical bottom displacements at the place of its location. Its measuring accuracy is about 1 nm, limit...
