Distinguishing Single and Linked Ruptures in the Laboratory and Nature

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes can grow either monotonically from a single, stressed patch or through linking multiple stressed regions. The distinction has implications for magnitude predictability with single ruptures requiring knowledge of the local stress state, while linked ruptures require knowing the global stress and energy distribution.

Hybrid XGBoost-RF-MLP model and PSO optimization for performance and emissions of CI engine using waste cooking biodiesel blends

Scientific Reports
Transesterification was used to create methyl ester from waste cooking oil (WCO). Diesel oil and biodiesel blends in 25, 50, 75, and 100% were developed and authorized by ASTM.

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Self‐Consistent Models of Earth's Mantle and Core From Long‐Period Seismic and Tidal Constraints

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Here we illustrate the use of parameterized models to address fundamental questions about Earth's mantle and core structure. For this, we invert a large set of normal‐mode center frequencies and quality (attenuation) factors, along with astronomic‐geodetic data, for the radial anelastic seismic structure of the Earth.

COVID-19 societal response captured by seismic noise in China and Italy

, 2020
Seismic noise with frequencies above 1 Hz is often called cultural noise and is generally correlated quite well with human activities. Recently, cities in mainland China and Italy imposed lockdown restrictions in response to COVID-19, which gave us an ...

The Seismological Laboratory: Past and Future [PDF]

, 1974
Moving into new and elaborate quarters is usually a matter of unqualified joy and anticipation. But anyone who has ever visited Caltech's Seismological Laboratory on North San Rafael Avenue will understand the mixed feelings with which the staff ...

Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.

Integration of Geological, Geophysical and Seismological Data for Seismic Hazard Assessment Using Spatial Matching Index

Journal of Geographic Information System, 2019
Probabilistic seismic hazard assessment (PSHA) takes into account as much data as possible for defining the initial seismic source zone model. In response to this, an algorithm has been developed for integration of geological, geophysical and seismological data through a spatial index showing the presence or absence of a potential seismic source ...

Inversion of Short‐Period Seismic Signals as a Tool to Understand Small‐Volume Rockslide Mechanics: The Case Study of the 26 January 2023, Lorgino (Crevoladossola, NW Italy) Rockslide

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract A small‐volume 6,000 m3 rockslide struck the Lorgino hamlet of Crevoladossola (NW Italy) just before 23:00 UTC on 26 January 2023, at the boundary of a nearby marble quarry. The rockslide severely damaged the mining infrastructure and halted operations for months, fortunately without causing injuries or casualties.
