Spatial heterogeneity in post-fire permafrost evolution as revealed by satellite radar observations

Abstract. Wildfires, which have profound impacts on permafrost environments, are expected to increase in frequency and intensity as a result of climate change. This study aims to enhance our understanding of how wildfires affect permafrost by investigating multiple Arctic tundra...

Potential glacier contributions to the 2024 La Bérarde flood

Abstract. On 20–21 June 2024, an unprecedented flood of the Etançons river caused important damage to the village of La Bérarde (Écrins, France). An analysis of the event showed that the flood was caused by the combination of an intense rain-on-snow event at high altitude and the...

Searching for the elusive “A” horizon in buried paleosols

ABSTRACT Presence of an A horizon in paleosols is important for taxonomic classification, interpreting pedogenic processes, and reconstructing paleoenvironments. However, identifying the A horizon in buried contexts is challenging because of potential erosion during burial and po...

Evaluation of a 3D Crustal Velocity Model for Northern Israel Using Wavefield Simulations

ABSTRACT We evaluate a recently developed 3D crustal velocity model for northern Israel using numerical simulations of seismic wave propagation for eighteen earthquakes (3≤Mw≤4.5). Synthetic seismograms were compared with observed recordings from the Israel Seismic Network in the...
