The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

open access: yesInternational Journal of Climatology, EarlyView.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

Discrete radiation sources of the 2024 Noto Peninsula earthquake: linking teleseismic pulses and near-field observations

open access: yesEarth, Planets and Space
Understanding the rupture process of large earthquakes is critical; however, standard rupture process inversions require stabilizing constraints, which can obscure which features are genuinely required by the data.

Real‐Time Coseismic Slip Estimation via the GNSS Carrier Phase to Fault Slip Approach: A Case Study of the 2016 Kumamoto Earthquake

open access: yesGeophysical Research Letters, 2019
We investigate the feasibility of Global Navigation Satellite System (GNSS)‐based deformation monitoring that detects coseismic fault slip directly from GNSS carrier phases without conventional positioning analysis.

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Coseismic crustal seismic velocity changes associated with the 2024 MW 7.5 Noto earthquake, Japan

open access: yesEarth, Planets and Space
The 2024 $$\hbox {M}_{\textrm{w}}$$ M w 7.5 Noto earthquake, Japan, was preceded by an intense seismic swarm thought to be driven by upward fluid migration.

Impact of volcanic eruptions on extratropical atmospheric circulations: review, revisit and future directions

open access: yesEnvironmental Research Letters, 2023
Understanding the impacts of volcanic eruptions on the atmospheric circulations and surface climate in the extratropics is important for inter-annual to decadal climate prediction. Previous studies on the Northern Hemisphere climate responses to volcanic

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Significant afterslip contribution to postseismic deformation in Sado Island following the 2024 Noto Peninsula earthquake: insights from two dense GNSS observation networks

open access: yesEarth, Planets and Space
This study investigated postseismic deformation resulting from the 2024 Noto Peninsula earthquake on January 1. Particular focus was placed on the displacement observed in Sado Island, which is located several tens of kilometers east of the eastern end ...
