Journal ArticleDOI
Complex hazard cascade culminating in the Anak Krakatau sector collapse.
Thomas R. Walter,Mahmud Haghshenas Haghighi,Mahmud Haghshenas Haghighi,Felix Schneider,Diego Coppola,Mahdi Motagh,Mahdi Motagh,Joachim Saul,Andrey Babeyko,Torsten Dahm,Valentin R. Troll,Frederik Tilmann,Frederik Tilmann,Sebastian Heimann,Sébastien Valade,Sébastien Valade,Rahmat Triyono,Rokhis Khomarudin,Nugraha Kartadinata,Marco Laiolo,Francesco Massimetti,Francesco Massimetti,Peter Gaebler +22 more
TL;DR: The authors show that Anak Krakatau exhibited an elevated state of activity several months prior to the collapse, including precursory thermal anomalies, an increase in the island’s surface area, and a gradual seaward motion of the southwestern flank.
Journal ArticleDOI

TL;DR: It is concluded that interaction between the pressure exerted by the subsiding reservoir roof and the physical properties of the subsurface flow path explain the gradual near-exponential decline of both the collapse rate and the intensity of the 180-day-long eruption of the Bárdarbunga volcano.
Journal ArticleDOI
Land subsidence in Iran caused by widespread water reservoir overexploitation
Mahdi Motagh,Thomas R. Walter,Mohammad Ali Sharifi,Eric J. Fielding,Andreas Schenk,Jan Anderssohn,Jochen Zschau +6 more
TL;DR: In this article, the authors show that the decline in groundwater levels is associated with land-surface deformation on local and regional scales, and combine water-level data with satellite radar observations to provide evidence for the prevalence of compacting aquifers in the country.
Journal ArticleDOI
Volcanic eruptions following M ≥ 9 megathrust earthquakes: Implications for the Sumatra-Andaman volcanoes
Thomas R. Walter,Falk Amelung +1 more
TL;DR: In this article, the authors present new evidence to suggest that earthquake-induced decompression of the volcano magma systems leads to such eruptions, which can ultimately lead to an eruption.
Journal ArticleDOI
Formation of caldera periphery faults: an experimental study
TL;DR: In this article, the authors evaluate characteristic structures resulting from doming, evacuation collapse, and cyclic resurgence in multi-stage caldera volcanoes, and analyse the consequential fault patterns and their statistical relationship to morphology and geometry.
