Intraslab Seismicity Near Subducted Seamounts Induced by the 2019 Large Slow Slip Event Offshore the Northern Hikurangi Subduction Zone, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract At the northern Hikurangi subduction zone, New Zealand, large slow slip events (SSEs) occur every 18–24 months. During the large 2019 SSE, ocean‐bottom seismometers were deployed directly above the main slip region. To analyze seismicity related to this event, we used machine learning and template matching techniques, along with a detailed ...

The 12 September 2016 ML5.8 midcrustal earthquake in the Korean Peninsula and its seismic implications

Geophysical Research Letters, 2017
The seismicity in the Korean Peninsula has increased since the 2011 Mw9.0 Tohoku‐Oki megathrust earthquake. Two strike‐slip earthquakes with magnitudes of ML5.1 and 5.8 occurred in the southeastern Korean Peninsula on 12 September 2016.

Using Dynamic Fourier Analysis to Discriminate Between Seismic Signals from Natural Earthquakes and Mining Explosions

AIMS Geosciences, 2017
A sequence of intraplate earthquakes occurred in Arizona at the same location where miningexplosions were carried out in previous years. The explosions and some of the earthquakes generatedvery similar seismic signals.

Proposed satellite laser ranging and very long baseline interferometry sites for crustal dynamics investigations [PDF]

Recommendations are presented for a global network of 125 sites for geodetic measurements by satellite laser ranging and very long baseline interferometry. The sites were proposed on the basis of existing facilities and scientific value for investigation

Determination of earthquake focal depths and source time functions in central Asia using teleseismic P waveforms [PDF]

, 2009
We developed a new method to determine earthquake source time functions and focal depths. It uses theoretical Green's function and a time-domain deconvolution with positivity constraint to estimate the source time function from the teleseismic P ...

Technological and infrastructure collaborative seismic research in Western Mexico [PDF]

, 2016
In February and March 2014, Spanish, Mexican and British scientists and technicians explored the western margin of Mexico, a region with a high occurrence of large earthquakes (> Mw = 7.5) and tsunami generation, on board the British Royal Research ...

Pervasive deformation of an oceanic plate and relationship to large >Mw 8 intraplate earthquakes: The northern Wharton Basin, Indian Ocean [PDF]

, 2015
Large-magnitude intraplate earthquakes within the ocean basins are not well understood. The Mw 8.6 and Mw 8.2 strike-slip intraplate earthquakes on 11 April 2012, while clearly occurring in the equatorial Indian Ocean diffuse plate boundary zone, are a ...

The 2009 Samoa–Tonga great earthquake triggered doublet [PDF]

, 2010
Great earthquakes (having seismic magnitudes of at least 8) usually involve abrupt sliding of rock masses at a boundary between tectonic plates. Such interplate ruptures produce dynamic and static stress changes that can activate nearby intraplate ...

Focused Mantle Upwelling Beneath the Southeastern Asian Basalt Province Revealed by Seismic Surface Wave Tomography

Geophysical Research Letters
Following the termination of seafloor spreading in the South China Sea (SCS) basin, abundant intraplate volcanism widely spreads in the Indochina block, SCS basin, and Leiqiong area, forming the Southeastern Asian Basalt Province (SABP).

Assessment of Damage Progression in Corner Buildings with Infill Walls During an Intraplate Earthquake in Mexico

Buildings
On 19 September 2017, an intraplate earthquake with a magnitude of Mw = 7.1 occurred in Mexico. Visual inspection reports following the earthquake indicated that 11% of high-risk structures and 35% of collapsed buildings were situated at block corners in
