  1. Videos of Test Blasts in preparation for the NSF Volcano Hazards Field-Scale Experiment Workshop, 2018, Buffalo

    15 Jun 2018 | Contributor(s):: Ingo Sonder, Greg A Valentine, Andrew Harp

    These test blasts were conducted in 2017, in preparation for the 2018 NSF Workshop on Volcano Hazards Field-Scale Experiments.For one event, six PETN charges (0.44 MJ energy each) were placed into prepared test beds ("pads"), made of unconsolidated crushed rock material. Charges...

  5. Size-distribution of scoria cones within the Eğrikuyu Monogenetic Field (Central Anatolia, Turkey)

    26 May 2018 | Contributor(s):: Göksu USLULAR, Gonca Kuşcu, Arda Arcasoy

    Eğrikuyu Monogenetic Field (EMF) is one of the five clusters of monogenetic volcanoes in Quaternary Central Anatolian Volcanic Province (CAVP). EMF consists mainly of scoria cones and a few maars (e.g. Kutören, Obruk). Previous studies on monogenetic volcanoes of CAVP mainly focused on...

  6. A new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements (SVL)

    17 Apr 2018 | Contributor(s):: Qingyuan Yang, Marcus I Bursik, E Bruce Pitman

    This tool presents a new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements. It is temporarily named "svl", which is short for Source Vent Locator. The method estimates the vent location by coupling semi-empirical models...

  7. Maar Volcano Location and Shape (MaarVLS) database

    04 Apr 2018 | Contributor(s):: Alison Graettinger

    The MaarVLS: Maar Volcano Location and Shape (pronounced marvelous) database establishes universal traits of Quaternary maar craters including typical sizes, shapes, and occurrence of these craters in different volcanic field types. The MaarVLS database includes manually digitized maar...
