Today’s Highlights
A strong day for hydrology-relevant research. A Science paper demonstrates SWOT satellite detection of a dispersive tsunami from the 2025 Kamchatka earthquake, showcasing the power of surface water remote sensing for constraining near-trench seismic sources and coastal hazard assessment. Two Nature Communications papers address climate-hydrology linkages: one reveals that recent tropical precipitation changes are primarily driven by spatially heterogeneous sea surface temperature patterns from anthropogenic forcing, while the other links the significant increase in Yangtze River basin summer floods since the 1990s to a shifted Indian Ocean wave regime affecting East Asian monsoon moisture transport.

SWOT detects dispersive tsunami tied to a near-trench source in the 2025 Kamchatka earthquake
Authors: Ignacio Sepúlveda, Bjarke Nilsson, Yao Yu, Matías Carvajal, Matthew Brandin, Alice-Agnes Gabriel et al.
Journal: Science · DOI: 10.1126/science.aeb8634
Matched topics: surface water
Tsunamis from large subduction earthquakes pose severe coastal hazards, yet their genesis near the trench remains poorly constrained by land-based seismic geodetic data and distant deep-water sensors. This study demonstrates that the SWOT (Surface Water and Ocean Topography) satellite detected a dispersive tsunami signal tied to a near-trench source in the 2025 Kamchatka earthquake, providing novel constraints on tsunami generation mechanisms and highlighting the value of satellite-based surface water observation for coastal hazard monitoring.
Tropical precipitation response to anthropogenic climate change in recent decades
Authors: Ligin Joseph, Pascal Terray, K. P. Sooraj, Sébastien Masson
Journal: Nature Communications · DOI: 10.1038/s41467-026-71187-4
Matched topics: river, climate change
Tropical rainfall plays a central role in the climate system, shaping ecosystems and societies. This study shows that recent tropical rainfall changes are primarily driven by spatially heterogeneous sea surface temperature patterns resulting from anthropogenic climate change. The findings have important implications for understanding and predicting precipitation variability and trends in the tropics under continued warming.
Frequent floods in the Yangtze River basin linked to a shifted Indian Ocean wave regime
Authors: Panini Dasgupta, SungHyun Nam, Michael J. McPhaden, Dong-Jin Kang, J. S. Saranya, M. K. Roxy
Journal: Nature Communications · DOI: 10.1038/s41467-026-70940-z
Matched topics: river, flood
Six major summer monsoon floods occurred in the Yangtze Basin during 1992–2024 compared to only one during 1960–1991. This significant increase in hydroclimatic extremes affected millions of people. The study links this shift to changes in the Indian Ocean wave regime that modulates moisture transport to East Asia, providing a new mechanistic understanding of the drivers behind increased flood frequency in one of the world’s largest river basins.
