An Evaluation of WRF‐Chem's Performance in Simulating PM2.5 in West African Cities

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract West Africa experiences some of the highest particulate pollution levels globally due to Saharan dust, biomass burning and urban emissions. Despite the severe health burden, air quality monitoring remains sparse. This study evaluates WRF‐Chem's performance in simulating PM2.5 levels across seven West African cities in 2021 using newly ...

Modeling the Probability of Tsunami Fire Ignition Based on Data From the 2011 Tohoku and 2024 Noto Peninsula Earthquakes, With Recommendations to Reduce Emerging Fire Risk in Tsunami Vertical Evacuation Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1116-1133, 25 April 2026.
ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not
