SCEC-ERI Summer School for Earthquake Science
Topic: Wave and Rupture Propagation with Realistic Velocity Structures
Dates: September 28-October 2, 2014
Location: Embassy Suites Mandalay Beach Hotel, Oxnard, CA
Participants: 50

Overview. The Southern California Earthquake Center (SCEC) and the Earthquake Research Institute of the University of Tokyo (ERI) has organized a Summer School for Earthquake Science September 28 through October 2, 2014. The theme for the Summer School is "Wave and Rupture Propagation with Realistic Velocity Structures". The program includes both lectures and exercises where participants will learn how complex velocity structure is represented and can be used to create seismograms from kinematic representations of earthquakes as point sources and propagating ruptures. One objective is for participants to construct ground motions for earthquake scenarios, which if used in a collective sense can be a method for complementing or creating hazard maps. Participants are given exercises so that they can run the various numerical methods with the supervision of the lecturers. Each participant will present a poster to share his/her research during evening sessions.

Computer Exercises

Software

The program includes a lab component, where students will work in small groups to perform several computer exercises. SCEC will provide laptops (loaded with the necessary software) for the students to share and use during these exercises. Participants are welcome and encouraged to use their own laptops for this part of the program.

We will provide the scientific software to be used in the workshop as a Virtual Box Image file. The file will need to be copied onto any computer used. The SCEC-ERI image is also available online. Copies of this file on USB disk drive will be available for installation on site.

If you decide to use your own laptop, you will need to install Virtual Box (a free download from Oracle: https://www.virtualbox.org) and then to load a virtual image containing all the required software on your computer.

Computer requirements. Windows 7/8 or a Mac OS X laptop with a recent version of the OS installed, 4GB RAM (8GB+ is definitely better!), and 50GB available on the hard drive. If your computer does not meet these minimum requirements (or if you experience problems setting up your laptop with our software), you are welcome to use/share one of our laptops.

Obtain and Install Virtual Box. If you are able, please plan to install Virtual Box on your computer before the computer exercises begin on Monday afternoon.

Instructions are also posted at SCEC wiki: https://scec.usc.edu/scecpedia/Install_Virtual_Box

  1. Download the Virtual Box software from Oracle (https://www.virtualbox.org/wiki/Downloads). This software is free to use. Retrieve a version that is appropriate for the Host Operating system of the computer you want to use. If your laptop runs Mac OS X, then retrieve a version of Virtual Box for Mac OS X. If your laptop runs Windows 8, retrieve a version of Virtual Box for Windows 8. We have tested the SCEC-ERI Image with Virtual Box Version 4.2.24 and higher.
  2. Follow the Virtual Box installation instructions and install Virtual Box on your computer (https://www.virtualbox.org/manual/UserManual.html). The installation procedure varies slightly based on the operating system you are using. It may require administrator permissions to install virtual box on some computers.

Technical Support. Please feel free to contact us (specifically, Fabio Silva) for help installing Virtual Box or the workshop software.

3D Structural Velocity Modeling / USR Framework (Monday 15:30 - 18:30)

Goal. This afternoon’s exercises are designed to familiarize you with the components of 3D structural velocity models, including basin structures, faults, and velocity parameterizations. We will accomplish this using the SCEC Unified Structural Representation (USR) for southern California and two tools developed to access and use this model: SCEC VDO, and interactive 3D visualization tool, and UCVM, which allows you to extract velocity values from these models.
