Study on VLF Electric Field Anomalies Caused by Seismic Activity on the Western Coast of the Pacific Rim

Atmosphere, 2023
In order to explore the correlation between earthquakes and ionospheric very low-frequency (VLF) electric field disturbances, this article uses VLF data observed by the China Earthquake Electromagnetic Satellite (CSES) to analyze very low-frequency ...

Subdaily Slow Fault Slip Dynamics Captured by Low‐Frequency Earthquakes

AGU Advances, 2023
AbstractGeodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies of the evolution of slow slip to its long‐term dynamics. Accompanying seismic low‐frequency earthquakes located precisely in time and space provide an opportunity to image slow slip dynamics at subdaily time scales.

Coseismic surface deformation from air photos: The Kickapoo step over in the 1992 Landers rupture [PDF]

, 2006
Coseismic deformation of the ground can be measured from aerial views taken before and after an earthquake. We chose the area of the Kickapoo-Landers step over along the 1992 Landers earthquake zone, using air photos (scale 1:40,000) scanned at 0.4 m ...

Synthesis of accelerograms compatible with the Chinese GB 50011-2001 design spectrum via harmonic wavelets: artificial and historic records [PDF]

, 2009
A versatile approach is employed to generate artificial accelerograms which satisfy the compatibility criteria prescribed by the Chinese aseismic code provisions GB 50011-2001.

Numerical analysis of seismic wave amplification in Nice (France) and comparisons with experiments [PDF]

, 2000
The analysis of site effects is very important since the amplification of seismic motion in some specific areas can be very strong. In this paper, the site considered is located in the centre of Nice on the French Riviera.

Deep learning detects uncataloged low-frequency earthquakes across regions

Seismica
Documenting the interplay between slow deformation and seismic ruptures is essential to understand the physics of earthquakes nucleation. However, slow deformation is often difficult to detect and characterize.

Low‐frequency earthquakes at the southern Cascadia margin [PDF]

Geophysical Research Letters, 2015
AbstractWe use seismic waveform data from the Mendocino Experiment to detect low‐frequency earthquakes (LFEs) beneath Northern California during the April 2008 tremor‐and‐slip episode. In southern Cascadia, 59 templates were generated using iterative network cross correlation and stacking and grouped into 34 distinct LFE families.

BLESeis: Low-Cost IoT Sensor for Smart Earthquake Detection and Notification

Sensors, 2020
The Internet of Things (IoT) has been implemented to provide solutions for certain event detection because of ease of installation, computing and communication capability, and cost-effectiveness. Seismic event detection, however, is still a challenge due

Ultra-Low-Frequency Electromagnetic Emissions Associated with Earthquakes

IEEJ Transactions on Fundamentals and Materials, 2004
Short-term earthquake prediction is still an urgent and important subject for seismo-active countries like Japan. There have been recently found a lot of convincing evidences on the presence of electromagnetic phenomena associated with earthquakes.
