  2. Mono-Inyo Tephra Database

    01 Aug 2017 | Contributor(s): Marcus I Bursik

    The Mono-Inyo Craters is a zone of active volcanism in California, USA, that extends from Mammoth Mountain and Long Valley caldera in the south to the islands of Mono Lake in the north.  This resource provides the citation for the Mono-Inyo tephra database.  The database can...

  3. Eruption data for ash-cloud model validation

    04 Apr 2013 | Contributor(s): Larry Garver Mastin, Costanza Bonadonna, Arnau Folch, peter webley, barbara stunder, Michael Pavolonis

    This is a collection of data, references, and links to data on well-documented eruptions whose observations can be used to validate ash-cloud transport models. Data include, among other things, plume height, duration, erupted volume, satellite observations, numerical wind fields, and grain-size...

  4. Granular Flow Experiments for Validation of Numerical Flow Models

    25 Jun 2016 | Contributor(s): Amy Webb, Marcus I Bursik

    Many types of geophysical flows such as debris avalanches and pyroclastic flows pose significant danger to both people and property. Understanding granular avalanche behavior and particle interaction during the course of a flow is very important in the development of granular flow models. Since...

  5. CALIPSO lidar ground track coordinates

    17 Nov 2010 | Contributor(s): Simon Carn

    These are ASCII text files containing lat/lon of the CALIPSO lidar ground track. Only the section of the orbit containing the Eyja ash cloud is included. The date and UTC time of the orbit segment is given in the filename.

  6. 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...

    Archive of NASA imagery for Iceland's Eyjafjallajokull Volcano, roughly from 2010-04-15 to 2010-05-26. http://science.larc.nasa.gov/asap/research-ash.html Text by Rob Gutro, NASA's Goddard Space Flight Center, Greenbelt, Md

  8. GFS 0.5 deg data for Puff from April 17 - 29 2010

    07 Oct 2010 | Contributor(s): Peter W Webley

    this is the global GFS data, every 6 hrs from April 17 2010 at 00:00. It is ready to be used by the Puff dispersion model, see example lines of codeNote i have defined the location of the wind field, the U, V and Z variables. I specify the model as reanalysis and this allows Puff to read the...

  10. Smithsonian's Global Volcanism Program Database

    25 Mar 2011 | Contributor(s): Paul Kimberly

    For more than three decades the Smithsonian's Global Volcanism Program (GVP) has compiled descriptions of both ongoing and past volcanism around the world in order to better understand the full range of Earth's eruptive activity, building its database the Volcano Reference File (VRF). To make...
