Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Generation and Dissipation of Infragravity Waves Over Natural and Engineered Chenier Plain During Hurricane Laura

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Infragravity (IG) waves play a crucial role in nearshore hydrodynamics and sediment transport; however, their generation and dissipation mechanisms during extreme storms remain challenging to assess due to limited data availability, site‐specific characteristics of natural landscapes, and anthropogenic effects.

Global Environmental Forcing of Coastal Waterline Variability Across Seasonal to Interannual Timescales

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract The position of the coastal waterline—the interface between land and sea—varies over time due to sedimentary and hydrodynamic processes influenced by climate variability. While previous studies have mainly focused on local morphodynamic or storm‐driven shoreline changes, the large‐scale climatic controls on global waterline variability remain ...

Overtopping over Vertical Walls with Storm Walls on Steep Foreshores

Journal of Marine Science and Engineering
As sea levels rise and extreme weather events become more frequent due to climate change, coastal urban areas are increasingly vulnerable to wave overtopping and flooding.

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

Assessing the Spatiotemporal Variability in Geotechnical Sediment Properties of Beach Cusps on a Sandy Beach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...

Using 3DF Zephyr to determine body‐worn camera position

Journal of Forensic Sciences, Volume 71, Issue 3, Page 1466-1472, May 2026.
Abstract Photogrammetry has been used consistently in forensic settings to document crime scenes three‐dimensionally. Traditionally, a large number of still photos are taken, and information from those photos is used to create a three‐dimensional (3D) model.

Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Mountain‐top spherules: Criteria to identify natural and synthetic particles

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 898-913, May 2026.
Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

Magnetic Signatures of a Plasma Wake Behind the Swarm Satellites

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study provides first observational evidence of a plasma wake behind ESA's Swarm satellites, manifesting itself by a brief magnetic field strength spike and bipolar field variations in transverse direction. These magnetic signatures occur only near the dip‐equator where the magnetic declination is close to zero.
