Characteristics of Seismic Energy Rate Functions of Shallow Tremors

Geophysical Research Letters
We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (

A comparison of seismic response to conventional and face destress blasting during deep tunnel development

Journal of Rock Mechanics and Geotechnical Engineering, 2019
A novel design of development face destress blasting was implemented during the construction of an experimental tunnel at great depth. A second tunnel was developed nearby using conventional blasting as a control.

A Seismological Study of the Michoacán-Colima, Mexico, Earthquake of 19 September 2022 (Mw7.6)

Geofísica Internacional, 2023
Michoacán-Colima earthquake of 19 September 2022 (Ms 7.6, Mw 7.6) ruptured the NW end of the Cocos-North American plate interface, causing severe damage to many towns and cities in the states of Michoacán and Colima. The damage was further exacerbated by

Infrasound Unmasks Flow Turbulence as an Additional Seismic Source in Debris Flows

Geophysical Research Letters
Debris flows radiate both seismic and infrasonic waves. According to previous studies, seismic energy is generated by the solid particle collisions with the riverbed and is dominated by the boulder‐rich front, while infrasound is produced by turbulence ...

Source complexity of the 2016 MW7.8 Kaikoura (New Zealand) earthquake revealed from teleseismic and InSAR data

Earth and Planetary Physics, 2018
On November 13, 2016, an MW7.8 earthquake struck Kaikoura in South Island of New Zealand. By means of back-projection of array recordings, ASTFs-analysis of global seismic recordings, and joint inversion of global seismic data and co-seismic InSAR data ...

Exploring the potentials and limitations of the time-reversal imaging of finite seismic sources [PDF]

Solid Earth, 2011
The characterisation of seismic sources with time-reversed wave fields is developing into a standard technique that has already been successful in numerous applications.

Carbon Dots: An Emerging Frontier for Green and Sustainable Civil Engineering Materials

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Traditional civil engineering materials (CE materials) are usually involved with high‐energy consumption during manufacturing, significant maintenance costs, and substantial environmental impacts throughout their life cycles. The progress of nanotechnology is catalyzing a green and sustainable transformation within the field.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1924-1941, 25 July 2026.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Seismic Velocity Variations Illustrate Hydrological and Ecohydrological Processes in a Mountain Watershed

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We employ passive seismic interferometry to study seismic hydrological responses in a snowmelt‐driven, semi‐arid catchment. Seismic velocity changes (dv/v) at 2–4 Hz and 4–8 Hz are analyzed from six stations along a hillslope transect between May and November 2023 and compared to precipitation, soil moisture, and groundwater level timeseries ...

Observational Evidence of a Very‐Low‐Frequency Earthquake (Mw 3.8) Leading to an Earthquake (Mw 4.2): Minto Flats Strike‐Slip Fault Zone, Central Alaska

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The physical conditions governing earthquake initiation are largely unknown, particularly in the minutes to seconds preceding rupture. While there is geodetic and seismic evidence of precursory activity in the hours to weeks prior to large earthquakes, the observational evidence immediately preceding the earthquake rupture is limited and ...
