Natural Hazards

Abstract This study provides a comprehensive assessment of drought dynamics based on 576 monthly observations from multiple stations in the Wadi Isser basin. Descriptive analyses revealed that near-normal conditions dominate the climatic profile, averaging 18–21 stations per month, although sporadic episodes of severe drought and intense wetness highlight the system’s vulnerability to extreme ano…

Abstract Heatwaves have caused more fatalities in Australia than any other natural hazard, and their frequency is expected to increase due to anthropogenic climate change. This growing risk underscores the urgent need to evaluate and enhance adaptation strategies for heatwaves to protect vulnerable community members. This study investigates historical trends in heatwave characteristics across New…

Abstract The ~ 115 km long Sultandağı Fault forms the southern boundary of the Quaternary Afyon–Akşehir Graben in western Türkiye and represents a major active normal fault within the regional extensional regime. The Mw 6.5 Çay earthquake of 3 February 2002 produced surface rupture along its central segment, confirming its seismogenic capacity. This study presents the first detailed paleoseismolo…

Abstract The timely detection of disasters is essential for effective emergency response. Traditional satellite-based monitoring provides accurate hazard observations but suffers from acquisition delays and weather-dependent imaging conditions. Therefore, recent research increasingly uses rapidly available digital data such as social media, news, and weather observations. However, most approaches…

Abstract Tsunami-transported boulders lie scattered across Okawa Point on Chatham Island, Aotearoa-New Zealand. These boulders, weighing up to 117 t, are distributed inland from coastal storm ridges, and are reported to have been transported by a tsunami 3500–4500 years ago. However, the origin of the tsunami responsible for this boulder scatter is unclear. In this study, boulder transport modell…

Abstract This paper seeks to examine how two authoritarian regimes in Europe handled earthquake and eruption disasters, and the extent to which deep-seated continuities in vulnerability and resilience are revealed which continue to affect responses regardless of the regime in power. In the middle decades of the twentieth century Italy and Portugal were both under the control of authoritarian regi…

Abstract Volcanic landscapes undergo rapid morphological change, with landslides representing a key process controlled by volcano-tectonic structures, topography, and climate. In remote regions, limited accessibility hampers systematic investigation of these processes. On Bioko Island (Equatorial Guinea), landslides occur in distinct spatial clusters despite widespread steep terrain, pointing to …
