#USGS map: “This map shows the #tephra fall associated with episode 43 of #Kīlauea’s episodic summit eruption, on March 10, 2026. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground. 🌋
Park volunteer & photographer Janice Wei was at Hawai'i Volcanoes National Park during this eruption & documented the dangers of the #Kīlauea plume. She wrote:
Look at the size of that #tephra flying out and & tiny ash too! Stay safe & protect yourself when watching the high fountains.
(3/10/2026)
Look at that Kawakawa #tephra layer embedded in loess. Two phases of deposition grading from coarse to fine 🤔
So cool!

South fountain has decreased to around 1000 feet (300 meters) high and north fountain is 700 feet (200 meters) high. #Tephra fall to the north and east has greatly reduced in the past hour. Fine ash and hair falling as far as #Hilo and #HPP.
Sunny with a chance of #tephra showers. The 43rd eruption at #Kilauea since Dec 2024 is leaving it’s mark with lofted rock fragments raining out along local roadways. Per USGS some are as small as coins to nearly as large as footballs near Halema’uma’u crater 3/10/2026
Flyer for a Geohorizon special issue call for papers, it reads: Tephra: from reconstructing past volcanic eruptions to modelling and forecasting future hazards Tephra produced during explosive volcanic eruptions can generate far-reaching social, economic, and environmental impacts with potentially devastating consequences for communities and livelihoods. By improving our understanding of how tephra is generated, transported and deposited - both during past events and ongoing activity - we can reduce these impacts and strengthen preparedness for future eruptions. This GeoHorizons volume will assemble a collection of papers that advance tephra studies, reflecting significant developments in the field over the past two decades. The volume will be organized into three sections: 1- Reconstructing past eruptions This opening section will highlight studies that use tephra to build eruption histories and reconstruct processes from historical and prehistoric explosive events. We welcome research involving field and deposit-based investigations, studies of sedimentary, archaeological and ice archives, modelling of past eruptions, and textural, geochemical and petrological analysis. 2- The generation, dispersion and sedimentation of tephra Focusing on recent or ongoing tephra-producing eruptions, this section invites studies examining trends in deposit characteristics such as grainsize and thickness, ash aggregation and particle settling processes, experimental work on plume dynamics and dispersion, and modelling of tephra generation transport and deposition. 3- Forecasting and mitigating the impacts of future explosive eruptions The final section looks to the future, with topics including tephra dispersion and impact modelling, climatic impacts and projections, volcanic hazard mapping, and applied studies that support risk reduction.

The red dashed line indicates the position of the Aso-3 distal tephra layer (SG14-6662). The green bar marks the interval of laminated sediments corresponding to Marine Isotope Stage (MIS) 5e. Modified from Francke et al. (2025).

McLean et al. (2026) shows that the Aso-3 caldera-forming eruption (SW Japan) marks the termination of MIS 6, providing a key tephrochronological marker for correlating East Asian paleoclimate records.

Dispersal index (Volcanology 🌋)
Dispersal index is a parameter in volcanology. The dispersal index D {\displaystyle D} was defined by George P. L. Walker in 1973 as the surface area covered by an ash or tephra fall, where the thickness is equal or more than 1/100 of the thickness of the fall […]
