The Virtual QuarkNet Center is a group of teachers, generally far from a geographic QuarkNet center but who work together using online tools to collaborate. Virtual QuarkNet Center teachers have monthly Sunday evening videoconferences during the school year and meet face-to-face once each summer. The teachers participate in cosmic ray studies using the cosmic ray e-Lab and in international masterclasses from their schools. The mentors, Antonio Delgado, a particle physicist at the University of Notre Dame, and Danielle McDermott, condensed matter physicist at Pacific Univerisity; emeritus mentor Dan Karmgard, another Notre Dame particle physicist; the lead teachers, Dave Trapp (email@example.com) and Mike Wadness, are QuarkNet fellows from Washington and Massachusetts, respectively. The QuarkNet Leadership Fellow who works with the group is Debbie Gremmelsbacher.
VQC is a group of QuarkNet teachers who are separated geographically but collaborate online.
Hello World! Questions from the powers that be on seismology:
- What are the types of seismic waves? How are they different from one another?
s-waves or shear waves (transverse!!!)
p-waves or pressure waves (longitudinal!!!)
- How do the various types of seismic waves propagate through the earth?
Didn't I just answer that?
- Why are seismic waves important to LIGO?
LIGO is sensitive to vibration. If seismic waves pass through the earth, it will move the beams. This can stretch one arm of the interferometer and create a signal,
- What are sources of seismic waves?
Motion of the plates - see cookie-techtonics for more information:
- How are seismic waves measured?
What is spacetime?
- What are gravitiational waves?
- Why do we seek to detect gravitational waves?
- What are the sources of gravitational waves?
Why seismic waves are important to LIGO
All kinds of things shake the ground and therefore affect the interferometers. These background vibrations have to be "subracted" just as background radiation is subtracted to determine radiation from a radioactive source.
sources of seismic waves
Almost anything that moves on the ground, hits the ground, or otherwise sends vibrations through the earth: earthquakes, trucks driving, mining explosions, weather phenomena, volcanoes, a gnat sneezing too close to the interferometer, etc. etc.
How are seismic waves measured
Seismometers have three instruments that measure movement in each of the 3 dimensions, By combining the three measurements scientists can determine exactly the direction, amplitude, and duration of seismic movement.
Compressional or P (for primary)
Transverse or S (for secondary)
P and S are called body waves because they travel or propagate throught the body of Earth. The latter two are called surface waves they travel along the Earth's surface and amplitude decreases with depth into the Earth.
First two, P and S are within the earth as compressions (longitudinal waves) and transverse waves.
Second two, Love and Rayleigh are surface wave.
Love waves are transverse waves that vibrate the ground in the horizontal direction perpendicular to the direction that the waves are traveling They are formed by the interaction of S waves with Earth's surface and shallow structure and are dispersive waves. Only can be measured on seismomaters that measure the horizontal ground motion.
Rayleigh waves are the slowest of all the seismic waves and the most complicated. The are dispersive so the particular speed at which they travel depends on the wave period and the near-surface geologic structure. Particle movement is eliptical and decreases with depth.
The LIGO interferometer mirrors can be affected by seismic waves and must be separated out. All the different earth shaking...hurricanes, earth quakes, etc. are background information that needs to be filtered out.

Participating teachers will be able to use the LIGO e-Lab to:
- Plot and interpret data recorded by LIGO seismic instruments
- Explain the importance of LIGO seismic data in gravitiational wave search
- Use LIGO seismic data to demonstrate classical physics concepts.

Great conference last Sunday night. Danielle, you are the bravest driver I know! I spoke with Kathy after our conference. She is doing well. Wadness, you were on the road, so I couldn't talk BB with you. I hope BRS spring training is going well, honest!
With permission from Ken and Dan, I have conferenced with and invited Allen Daniels, a physics teacher in the Parkway system in St. Louis regarding joining our group. I used his school email and sent an invite. He should be expecting this since I conferenced with him in person in StL. He was previously a virtual member when he was working at Crossroads school in St. Louis, but I don't know what his level of participation was back then. His email is
Enjoy break if you are on one. I had cervical disc surgery the Monday after our conference and am convalenscing at home.
And hey, everyone who does not have a pic of themselves in the drupal, get a pic in there. I like the pictures.

Virtual QuarkNet is a group of far flung, often isolated American high school science teachers from Boston and Atlanta, to the northwest coast of Washington, and Shanghai. Mentors Antonio Delgado and Dan Karmgard are assisted by lead teachers Mike Wadness and Dave Trapp. In the 2014-15 school year they held 10 monthly meetings via Sunday evening (Monday morning in Asia) video conference. Attendance varied from 6 to 8 with most meetings attended by 7 participants. Sessions typically lasted from an hour to 90 minutes. Several sessions had guest speakers and nearly all of them included discussions of the latest physics discoveries or theories.
Many of the group members have and use cosmic ray detectors at their school and most of the group also had high school students participate in the Masterclass.
The group also typically gathers for a couple days each summer at a site which offers new insights into physics. In early August 2015 the group gathered in Albuquerque and Los Alamos New Mexico with the crucial assistance of physicist Danielle McDermott. In New Mexico the group had the opportunity to visit and tour the Very Large Array (VLA) which has been detecting the faintest radio signals from near the time of the Big Bang. At Los Alamos, the group enjoyed a variety of talks that featured the history of Los Alamos, the use of bacteria to do work on a system, a connection between Faraday and the Higgs, and the Mars Curiosity Rover. In addition the group took advantage of the clear, high desert sky to do some spectacular star gazing facilitated by our resident astronomer Jim Small. The group ended its workshop with a visit to Bandelier National Monument to hike through the ancient pueblos. Thank you to our mentors and especially to Danielle McDermott for arranging a valuable summer workshop.

The group also typically gathers for a couple days each summer at a site which offers new insights into physics. In 2014 the group gathered in Spearfish SD with the assistance of members of the Spearfish QuarkNet group. They learned of the new EQUIP Java cosmic ray detector interface, the new detector data blessing protocols and interface support, viewed the new International Linear Collider Masterclass (using simulated data), visited research activities on the Black Hills State campus, visited the Sanford underground Laboratory learning about the latest neutrino and dark matter research, and sat in on a couple CETUP conference talks. Time permitted many of the members to visit other local areas such as Mount Rushmore, the Crazy Horse Memorial and Devil’s Tower.
