Abstract On Dec. 22, 2018, at approximately 20:55–57 local time, Anak Krakatau volcano, located in the Sunda Straits of Indonesia, experienced a major lateral collapse during period eruptive activity that began June. The discharged volcaniclastic material into 250 m deep caldera southwest which generated tsunami with runups up to 13 on adjacent coasts Sumatra and Java. caused least 437 fatalities, greatest number from volcanically-induced since catastrophic explosive eruption 1883 sector...
Cetyltrimethylammonium bromide (CTAB)-based methods are widely used to isolate DNA from plant tissues, but the unique chemical composition of secondary metabolites among species has necessitated optimization. Research articles often cite a "modified" CTAB protocol without explicitly stating how had been altered, creating non-reproducible studies. Furthermore, various modifications that have applied not rigorously reviewed and doing so could reveal optimization strategies across study...

We report on integrated geomorphological, mineralogical, geochemical and biological investigations of the hydrothermal vent field located floor density-stratified acidic (pH ~ 5) crater Kolumbo shallow-submarine arc-volcano, near Santorini. features rare geodynamic setting at convergent boundaries, where arc-volcanism seafloor activity are occurring in thinned continental crust. Special focus is given to unique enrichments polymetallic spires Sb Tl (±Hg, As, Au, Ag, Zn) indicating a new...
Despite their global societal importance, the volumes of large-scale volcanic eruptions remain poorly constrained. Here, we integrate seismic reflection and P-wave tomography datasets with computed tomography-derived sedimentological analyses to estimate volume iconic Minoan eruption. Our results reveal a total dense-rock equivalent eruption 34.5 ± 6.8 km³, which encompasses 21.4 3.6 km³ tephra fall deposits, 6.9 2 ignimbrites, 6.1 1.2 intra-caldera deposits. 2.8 1.5 material consists...
Abstract This paper presents the design and deployment of Hydrogen Epoch Reionization Array (HERA) phase II system. HERA is designed as a staged experiment targeting 21 cm emission measurements Reionization. First results from I array are published early 2022, system nearing completion. We describe discuss progress on commissioning future upgrades. As designated Square Kilometre pathfinder instrument, we also show number “case studies” that investigate systematics seen while system, which...

The Plinian phase of the May 18, 1980, Mount St. Helens eruption is modeled as a steady state discharge dacitic magma from reservoir at 7–10 km depth rate 1.94×10 7 kg/s. Properties magma, including preeruption volatile content (4.6% in melt), temperature (920°–940° C), and confining pressure (190–250 MPa) are constrained by petrologic studies. Mass rate, viscosity, independent estimates ascent velocity suggest 95‐m‐diameter conduit below vapor saturation. Dispersal pyroclasts indicate...
Summary Marginal basins adjacent to oceanic island arcs receive volcaniclastic debris from the bordering volcanic arc, back-arc spreading centre, and, a lesser degree, remnant arc. The arc is volumetrically most important source, with abundant volcaniclastics being produced by explosive subaerial and/or subaqueous eruptions and secondary erosion of complex. Transport material deeper parts marginal occurs passive settling through water column or variety sediment gravity flows generated...
Abstract Caldera-forming eruptions of island volcanoes generate tsunamis by the interaction different eruptive phenomena with sea. Such are a major hazard, but forward models their impacts limited poor understanding source mechanisms. The caldera-forming eruption Santorini in Late Bronze Age is known to have been tsunamigenic, and caldera collapse has proposed as mechanism. Here, we present bathymetric seismic evidence showing that was not open sea during main phase eruption, flooded once...

The Late Bronze Age ‘Minoan’ eruption of Santorini, Greece occurred from within an existing caldera. Low-temperature pyroclastic flow emplacement on shallow slopes outside the caldera can only be consistent with being filled products that are not preserved. Field observations and seismic reflection surveys suggest this missing material has been downfaulted. volume infill is estimated as 18–26 km 3 dense rock equivalent (DRE), increasing total Minoan deposits to 78–86 DRE making it largest...
Abstract This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate role source heterogeneity controlling variability within Santorini volcanic field central Aegean arc. Kolumbo, situated 15 km northeast Santorini, last erupted 1650 AD and is thus closely associated with system space time. Samples taken by remotely‐operated vehicle that were analyzed for major element, trace element Sr‐Nd‐Hf‐Pb isotope composition include...
