Geophysical Monograph Series, Page 117-131., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Tephra layers in the marine environment: A review of properties and emplacement processes
Geological Society Special Publication, 2021 This review focusses on the recognition of volcanic ash occurrences in marine sediment cores and on using their appearance and properties to deduce their origin.

Global Biogeochemical Cycles, 2021 Preservation of organic carbon (OC) in marine sediments exerts a major control on the cycling of carbon in the Earth system. In these marine environments, OC preservation may be enhanced by diagenetic reactions in locations where deposition of fragmental

Characterizing Drivers of Asia's Black Elephant Disaster Risks
Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Asia has the fastest growing population and economy, but it is also the most disaster‐prone region in the world. Resilience to disaster impacts from natural hazards will be key to the long‐term sustainability of this rapidly growing region. The first step to building resilience is to identify the key threats that this region faces. We describe

Remotely assessing tephra fall building damage and vulnerability: Kelud Volcano, Indonesia
Journal of Applied Volcanology, 2020 Tephra from large explosive eruptions can cause damage to buildings over wide geographical areas, creating a variety of issues for post-eruption recovery. This means that evaluating the extent and nature of likely building damage from future eruptions is
