Helioseismic analysis of the solar flare-induced sunquake of 2005 January 15 [PDF]

, 2006
We report the discovery of one of the most powerful sunquakes detected to date, produced by an X1.2-class solar flare in active region 10720 on 2005 January 15.

Evaluating Deep‐Learning‐Based Earthquake Detection in a Sparse Coastal Network: Insights From the 2017 Changdao Swarm, Eastern China

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Constructing reliable earthquake catalogs in regions with sparse station coverage and strong noise remains challenging. We evaluate the performance of a deep‐learning–based detection and location workflow (LOC‐FLOW) using the 2017 Changdao offshore earthquake swarm in eastern China.

Did they blow it? Time-lapse velocity variations during an open-pit mine slope failure using seismic noise interferometry

Seismica
Landslides are geological events that directly impact thousands of people every year and cause significant loss of life. Landslides are often triggered by extreme weather events or earthquakes.

Multi-color Cavity Metrology [PDF]

, 2012
Long baseline laser interferometers used for gravitational wave detection have proven to be very complicated to control. In order to have sufficient sensitivity to astrophysical gravitational waves, a set of multiple coupled optical cavities comprising ...

Dead Sea Basin Imaged by Ambient Seismic Noise Tomography [PDF]

Pure and Applied Geophysics, 2011
In the framework of the Dead Sea Integrated Research project (DESIRE), 59 seismological stations were deployed in the region of the Dead Sea Basin. Twenty of these stations recorded data of sufficiently high quality between May and September 2007 to be used for ambient seismic noise analysis.

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Improving the sensitivity of future GW observatories in the 1-10 Hz band: Newtonian and seismic noise [PDF]

, 2010
The next generation gravitational wave interferometric detectors will likely be underground detectors to extend the GW detection frequency band to frequencies below the Newtonian noise limit.

Seismic anisotropy from 6C ground motions of ambient seismic noise

Journal of Geophysical Research: Solid Earth
AbstractWe propose a new approach capable of measuring local seismic anisotropy from 6C (three‐component translation and three‐component rotation) amplitude observations of ambient seismic noise data. Our recent theory demonstrates that the amplitude ratio of 6C cross‐correlation functions (CCFs) enables retrieving the local phase velocity.

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Rayleigh Waves From OHANA OBSs in the Northeast Pacific Ocean Reveal Low Deep Shear Velocities and Pervasive Azimuthal Anisotropy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The 2021–2023 OHANA ocean‐bottom seismometer deployment in the northeast Pacific Ocean provides a rich data set for seismic studies to explore the crust, lithosphere and asthenosphere in a 600 km wide region about 1,500 km northeast of Hawaii, west of the Moonless Mountains. The study area covers mainly 40‐to‐55 Myr‐old Pacific lithosphere.
