The collapse discharged volcaniclastic material into the 250 m deep caldera southwest of the volcano, which generated a tsunami with runups of up to 13 m on the adjacent coasts of Sumatra and Java. The tsunami caused at least 437 fatalities, the greatest number from a volcanically-induced tsunami since the catastrophic explosive eruption of Krakatau in 1883 and the sector collapse of Ritter Island in 1888. For the first time in over 100 years, the 2018 Anak Krakatau event provides an opportunity to study a major volcanically-generated tsunami that caused widespread loss of life and significant damage. Here, we present numerical simulations of the tsunami, with state-of the-art numerical models, based on a combined landslide-source and bathymetric dataset. We constrain th...

Research paper thumbnail of Post-eruptive flooding of Santorini caldera and implications for tsunami generation

Such tsunamis are a major hazard, but forward models of their impacts are limited by poor understanding of source mechanisms. The caldera-forming eruption of Santorini in the Late Bronze Age is known to have been tsunamigenic, and caldera collapse has been proposed as a mechanism. Here, we present bathymetric and seismic evidence showing that the caldera was not open to the sea during the main phase of the eruption, but was flooded once the eruption had finished. Inflow of water and associated landsliding cut a deep, 2.0–2.5 km3, submarine channel, thus filling the caldera in less than a couple of days. If, as at most such volcanoes, caldera collapse occurred syn-eruptively, then it cannot have generated tsunamis. Entry of pyroclastic flows into the sea, combined with slumping of submarine pyroclastic accumulations, were the main mechanisms of tsunami prod...

The submarine volcano Kolumbo, located seven kilometers northeast of Santorini and associated with Santorini\u27s tectonic system, erupted explosively in 1650 A.D., resulting in fatalities on the island of Thera [Fouqué, 1879]. A large fraction of the erupted products from the Minoan eruption has been deposited in the sea but, up to now, only has been studied in distal marine sediments. As part of a collaborative project between the University of Rhode Island (Narragansett), the Hellenic Centre of Marine Research (Athens, Greece), and the Institute of Geology and Mineral Exploration (Athens), a marine geological survey was conducted around Santorini from April to June...

Reexamination of cores and analysis of grain size, turbidite frequency, carbonate content, and clay mineralogy, together with new nannofossil age determinations, were used to revise shipboard lithostratigraphies and interpret the sedimentologic history recorded at each site.The results of our analyses show that sedimentation on the inner trench slope and the impinging NDR has been significantly affected by the collision process. Uplift associated with subduction of the NDR beneath the New Hebrides Island Arc resulted in the emergence of Espiritu Santo Island and created a robust source of epiclastic sediment for the forearc area. Distribution of this material into deeper water has been modulated by Pleistocene sea level changes, which have influenced the freq...

Research paper thumbnail of Hydrothermal oxide and nontronite deposits at Seamount 3, Wolf-Darwin lineament, Galapagos Archipelago, Ecuador

X-ray diffraction, ICP-MS/ICP-AES, and SEM-EDS analyses show that this deposit is chemically and mineralogically similar to other deep-sea hydrothermal nontronites, indicating a formation temperature of about 30o to 50o Celsius. These Fe-Si-oxides and Fe-rich Al-poor nontronite deposits contain about 38-51 weight % SiO2 and 40-50 weight % Fe2O3. Although hydrothermal nontronite has been sampled at a number of sites by coring and dredging, this is the first in situ documentation of its sinuous, tubular structure on the seafloor. Imageanalysis of ROV imagery suggests that this unusual pattern might be controlled by fluid pathways in the underlying pillow lavas.
