Ligo E Lab

  1. 1. LIGO e-LabLaser Interferometer Gravitational Wave Observatory<br />Using Seismic Data in the classroom.<br />
  2. 2. Design flowchart for LIGO e-Lab<br />
  3. 3. LIGO Environmental Sensors: Seismometers<br />Seismometers measure seismic waves that travel through the earth. A magnetic mass is suspended between two coils. As seismic waves pass through the seismometer, the coils move, but the mass remains at rest because of its inertia. The movement of the coils relative to the magnetic mass induces an electric current that can be detected and plotted on a graphical interface. <br />
  4. 4. LIGO EnvironmentalSensors: Tiltmeters<br />Tiltmeters measure small changes in the tilt of the ground or of a structure. Tiltmeters are analogous to a highly sensitive carpenter&apos;s level with an electronic output.<br />
  5. 5. LIGO Environmental Sensors: Magnetometers<br />Magnetometers measure changes in the Earth&apos;s magnetic field. Magnetometers can be used to monitor the effects of solar storms near the Earth. They can also be used to predict auroras.<br />
  6. 6. LIGO Environmental Sensors: Anemometers<br />Anemometers measure the velocity and direction of the wind at all five LIGO data stations.<br />
  7. 7. Location of Sensors<br />EX<br />MX<br />Vault<br />MY<br />EY<br />LVEA<br />
  8. 8. We have the option of plotting single sensor data in basic mode or multiple channel Plots in Advanced mode<br />BASIC<br />ADVANCED<br />

  11. 11. We have developed an auto plotting map for immediate feed back<br />
  12. 12. For additional in-depth studies we have provided a collaborative map to minimize tedious re-work.<br />
  13. 13. Each plotted point contains basic information and a link to an e-Lab Poster.<br />
  14. 14. Each poster will provide additional information with links to source data and a link to the specific earthquake site map.<br />
  15. 15. Choose an Earthquake to investigate from USGS or other source<br />
  16. 16. Information to gather<br />Date of earthquake<br />Time of earthquake<br />Latitude of earthquake<br />Longitude of earthquake<br />Magnitude of earthquake<br />Depth of focus of earthquake<br />Distance to LIGO<br />Estimated travel time of earthquake waves (USGS travel time calculator or rule of thumb)<br />Actual travel time of earthquake waves<br />
  17. 17. Gathering Data using Bluestone<br />First determine your investigation level.<br />Beginningonly allows one channel to be plotted on a graph.<br />BothIntermediateand Advancedallow for multiple channels on one plot.<br />
  18. 18. Data Selection<br />1) Choose site location<br />2) Choose data monitoring tool<br />3) Choose location of sensor<br />4) Choose frequency <br /> of wave to plot<br />
  19. 19. Begin analysis<br />*No options for beginners*<br />Click on “GO”<br />
  20. 20. Task execution<br />Just wait for plot<br /> to Be calculated and <br />drawn<br />
  21. 21. Plotted graph of seismic activity<br />You may save the plot using<br /> these options<br />
  22. 22. We have added a line for the actual time of the Earthquake and the calculated arrival time to LIGO.<br />
  23. 23. What can we do with this information?<br />Map Plate boundaries.<br />Study earthquake wave propagation rates.<br />Graph earthquakes focus depth.<br />Changes in wave velocity based on rock types (Continental/Oceanic).<br />Compare earthquake intensity and depth.<br />…<br />
