High‐Resolution Regional Atmospheric Simulation of Precipitation and Isotopes in Central America
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.Abstract With advances in global and regional circulation models, the high‐resolution simulation of atmospheric variables has become increasingly feasible. In this study, we use IsoRSM, an isotope‐enabled regional spectral model, to improve the simulation of precipitation and its isotopic composition over tropical Costa Rica, which is marked by a ...

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Volcano‐tectonic (VT) earthquakes generated during dike propagation provide useful constraints on stress changes in volcanic systems. During the 1998 pre‐eruptive unrest at Piton de la Fournaise, ∼600 VT earthquakes were recorded. Using manually picked first‐motion polarities and corrected station metadata, we calculated more than 400 high ...

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

The sand grain and the butterfly. Instability in geodesy and geophysics
, 1997 The problems of convergence of series in celestial mechanics and of certain series in geodesy (Molodensky's series and spherical harmonics) show similar features, involving a curious instability. This is imaginatively expressed as the « butterfly effect»

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract How crustal deformation responds to complex mantle flow in continental back‐arc settings remains poorly constrained. Here, we develop a Bayesian working‐likelihood approach to estimate crust‐averaged azimuthal anisotropy from P‐wave receiver functions. The method separates crust‐averaged velocity anisotropy from dip‐related apparent anisotropy

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

Current geodetic deformation of the Colli Albani volcano: a review
, 2010 The quiescent Colli Albano volcano is presently characterized by moderate-intensity earthquakes, seismic swarms, gas emissions and ongoing uplift that reflects the current evidence of its residual activity. An uplift of230 cm over the last 43 years was

Numerical simulation of tsunami generation by cold volcanic mass flows at Augustine Volcano, Alaska [PDF]
, 2006 Many of the world's active volcanoes are situated on or near coastlines. During eruptions, diverse geophysical mass flows, including pyroclastic flows, debris avalanches, and lahars, can deliver large volumes of unconsolidated debris to the ocean in a ...
