2018 Spring EW Course

I just took the week long ISTI EW class, as the saying goes, ‘like drinking from a firehose’ it was a fun and rewarding week. I learned a lot! – Angel Rodriguez

2018 Earthworm Course in Saratoga Springs, NY, April 30 – May 4

This April 30 through May 4, ISTI will host another of our popular Earthworm training courses in Saratoga Springs, New York. Earthworm is the popular open source regional earthquake data acquisition and location processing system. Originally developed by the USGS, it is now maintained and moved forward by a group of developers that ISTI organizes.

In the course, we will be providing an expert’s insight into the system. You will learn tricks and tips from our decades of experience operating and programming Earthworm. You will learn how to set up regional automatic earthquake detection with the latest release of Earthworm.

This course will be useful to anyone setting up, managing, tuning, or developing for an Earthworm system.

The immersive hands-on course will cover:

  • Installation
  • Configuration
  • Troubleshooting
  • Archiving and Playback of data
  • Data exchange
  • Visualization tools
  • Overview of various non-Earthworm post-processing options
  • Tuning for Earthquake Location and Magnitudes
  • Programming new modules, learning APIs

In addition, we will provide a tuning session for anyone that wants to bring their network’s Earthworm configuration to the course. We will show you how to playback your data and tune the earthquake location engine.

The course will be taught by Paul Friberg and Stefan Lisowski who have a combined experience with Earthworm of over 30 years!

Deadline: March 31st:  We strongly encourage you to sign up as soon as possible due to limited seating. Contact ISTI for availability as the course is limited to 12 participants.

Course Outline

Please note, these may vary based on class interest and time available.

  1. Earthworm Setup – This will cover the basics of getting an Earthworm system up and running. The class will configure an Earthworm system with a seedlink feed from remote stations’ data loggers. We will store the data into a WaveServerV and Winston Waveserver, and pull data to files.
  2. Earthworm Configuration – This will include initial configuration, and will cover tricks and frequently seen problems with earthworm configurations.
  3. Basic Modules for Troubleshooting – Sniffwave, sniffring, get menu, logging review, debug and verbosity flags.
  4. Advanced Earthworm Modules – We will review an existing and running Earthworm system (CalTech) that processes over 370 stations. In addition, we will cover AQMS for those students interested in learning more about those systems.
  5. Earthworm Library – students will learn the basic Earthworm APIs for messaging, logging, configuration, threads, and wave server API/Protocol. How to make sure the work you do to a library is compatible across operating systems, etc.
  6. Playback – how to playback events for turning a system: waveman2disk, trig2disk, and tank player. The class will work with an existing tank and run it through the picker, binder, and hyp2000 via the Earthworm MegaModule.
  7. Locating Events – The Picker/Binder and Earthworm MegaModule will be explored and parameters explained.
  8. Programming an EW Module – The class will write an Earthworm module that interacts with information in a shared memory ring.

Note: If you’d like to learn something specific, please contact us in advance and we will attempt to address your interests.

    • If you’re using Windows, then Microsoft Visual C Compiler (2003 or newer). Free Microsoft Visual Studio Express is okay.
  • For the Programming Day: Some experience with C programming is important.

It is strongly recommended that students have a background in basic seismology and seismology applications.

Travel Considerations

Accommodation in Saratoga Springs

The course will take place at The Hampton Inn & Suites Saratoga Springs Downtown, which is also conveniently situated near restaurants in downtown Saratoga. We recommend staying at the Hampton Inn; we typically get a small discount for students when we commit to a block of rooms for the course.

Other options:

The Inn at Saratoga has a somewhat quaint and historic look to it. It is a bit more expensive than the Downtowner had been, but it is a comfortable place to stay.

The Holiday Inn is across the street from the Inn at Saratoga, and is
slightly more expensive, if you prefer something more modern.

There are two Hilton hotels in Saratoga, if you choose a Hilton, this one is conveniently located at the other side of Broadway from Van Dam St.


Travel from the Albany Airport

The nearest airport is in Albany, NY (ALB). Unfortunately, there is no shuttle from the Albany Airport to Saratoga Springs. The most convenient way is to take an expensive taxi or rent a car. The buses and trains are limited.

If you are going to rent a car and would be willing to share your ride, or if you would like to request a ride with another participant who has rented a car and is willing to travel from the airport, contact ISTI and we will try to coordinate.

Taking the train from New York City

Amtrak offers service between New York City (New York Penn Station) to Saratoga typically twice a day. Booking these tickets in advance is advised as they do sell out. From the train station to the hotel would be a taxi ride, as it is a bit far to walk.

Taking a bus from New York City

There are a number of bus companies, including Megabus, Adirondack Trailways, and Greyhound that offer round-trip service between New York City and Saratoga.

Getting around Saratoga Springs

There are at least 20 restaurants and a supermarket within walking distance of the hotel. You may want to consider not renting a car unless you plan on exploring the area on your own.

Things to do in Saratoga Springs

For a small city, Saratoga Springs has a strong cultural component. Home to the National Museum of Dance and Hall of Fame and the National Racing Museum and Hall of Fame, Saratoga boasts an excellent summer nightlife. Live music may often be found within walking distance of the hotel almost every evening. Particular highlights include:

Deadline: March 31st:  We strongly encourage you to sign up as soon as possible due to limited seating. Contact ISTI for availability as the course is limited to 12 participants.
