Volcanic eruptions on land create hot and fast pyroclastic density currents, triggering tsunamis or surges that travel over water where they reach the ocean. However, no field study has documented what happens when large volumes of erupted volcanic material are instead delivered directly into We show how rapid emplacement onto steep submerged slopes triggered extremely (122 kilometers per hour) long-runout (>100 kilometers) seafloor currents. These currents were faster than those by...
The impacts of large terrestrial volcanic eruptions are apparent from satellite monitoring and direct observations. However, more than three quarters all outputs worldwide lie submerged beneath the ocean, risks they pose to people, infrastructure, benthic ecosystems remain poorly understood due inaccessibility a lack detailed observations before after eruptions. Here, comparing data acquired between 2015 - 2017 3 months January 2022 eruption Hunga Volcano, we document far-reaching diverse...

A large sandstone rock art site, Marra Wonga, near Barcaldine, central Queensland, is the focus of this paper. This 160-metre-long shelter estimated to have over 15,000 petroglyphs, which are mostly animal tracks, lines, grooves and drilled holes, as well 111 hand-related object stencils. There also a cluster human-shaped foot petroglyphs on floor shelter, some with six or more toes. Unique compositions wall include seven large, engraved star-like designs pits snake-like running across...
Abstract. Recurring transboundary haze from Indonesian wildfires in previous decades significantly elevated particulate matter (PM) concentrations Southeast Asia. During that event on October 10 to 31, 2015, we conducted a real-time observation of non-refractory submicron PM (NR-PM1) Singapore using an Aerodyne aerosol mass spectrometer. Simultaneously, characterized carbonaceous components and organic (OA) tracers fine (PM2.5) samples support source apportionment the online measurements....
40 Ar/ 39 Ar muscovite dates from mainly pegmatites the Tusas, Sandia and Manzano Mts provide cooling ages between about 1450 1330 Ma in general record diachronous across region.Samples Petaca District Tusas have comparatively young 1406 1328 whereas data are generally older than 1400 steps their age spectra that approach igneous intrusion 1440 1460 Ma.Our initial goal of directly dating using argon was not successful due to high (>500°C) ambient country rock temperatures related 1.47 1.40...
