************************************************************************************************
Dear Colleagues,
We would like to draw your attention to a full day VHub.org workshop at the 2013 IAVCEI General Assembly, to be held in Kagoshima, Japan, on July 25th.
Topics to be covered include on-line models dealing with volcanic processes and hazards, educational materials, the submission process, using the ‘groups’ feature, privacy rights, the VHub.org workspace, numerical models available for download, and more. Introductions to numerous online simulation and analysis tools will be given, including:
Pingu: Pingu is a tool for plotting standard major element and trace element diagrams.
BET_VH: The main purpose of this software is to provide graphically supported computation of long-term probabilities of hazardous volcanic phenomena (i.e., lava flows, tephra fall, pyroclastic flows, lahars, etc.) through a Bayesian Event Tree model for Volcanic Hazards (BET_VH).
Windre: This tool allows you to calculate the statistics of wind direction and speed at or near active volcanoes. Currently there are 536 volcanoes in the database. All these volcanoes have exhibited historical activity based on the Smithsonian database. The wind data used in this tool span 22 years (1990-2011).
Hazmap: This tool simulates sedimentation of volcanic particles from discrete point sources. It can also evaluate the probability of overcoming a given loading threshold given a set of wind profiles.
Puffin: This tool is a theoretical model of a volcanic plume, based on applying the equations of motion in a plume-centered coordinate system. Puffin suggests that the interaction between a volcanic plume and wind causes enhanced entrainment of air and horizontal momentum, plume bending, and a decrease in plume rise height at constant eruption rate.
Energy Cone: This tool is a simple methodology that can be used to estimate the runout and inundation area of pyroclastic density currents, landslides and other mass movements. It outputs the Energy Cone contour on top of a hillshade image calculated from a DEM. If the DEM is in degrees, a kmz file is created which can be downloaded for visualization with Google Earth.
Tephra2: Tephra2 is used to forecast tephra accumulation given an explosive volcanic eruption. This tool is available as a forward model, an educational resource, and as a resource for probabilistic hazard analysis.
Titan2D: The Titan2D toolkit is used for modeling of geophysical mass flows (volcanic flows, avalanches, landslides etc.) over natural terrain .
Each of these tools is installed and available for all to use on VHub.org. Come to the workshop for explanations, help, and hands-on exercises with these and other VHub.org tools. Sessions will be presented by tool developers and/or experienced users familiar with the assumptions, validation exercises, constitutive equations, and VHub.org interface of the tool they will present. Get your questions answered and find out where to go for more detailed information about any particular model. Get ideas for how to integrate these tools into your research, work and/or classroom. Find out how to become a tool developer and share the models that you have designed for your own research with the greater volcanological community.
Registration is free but is required no later than May 1st for participation. Registrants who are unable to participate are asked to contact the organizers no later than May 15th so that space can be allocated to other applicants. You will need to bring your own computer. Some computers may be available for renting at participant’s expense.
