Presentation Transcript

  1. Borehole radial tilt record from rim of the summit caldera since July 1. Positive change is inflation, negative change in deflation.

  2. Change in line length between GPS stations spanning the summit caldera since January 1. Positive change is inflation, negative is deflation.

  3. Borehole radial tilt record from the north flank of Pu’u ’Ō’ō since July 1. Positive change is inflation, negative change in deflation.

  4. Change in line length between GPS stations spanning the rim of Pu’u ’Ō’ō Crater since January 1. Positive change is inflation, negative is deflation.

  5. Change in line length between GPS stations spanning the flanks of Pu’u ’Ō’ō. Positive change is inflation, negative is deflation.

  6. Change in line length between GPS stations spanning the east rift zone. Positive change is extension, negative change is contraction.

  7. Continuous gravity data from caldera floor on July 24 with Webcam images from summit vent. 23:30 7/24/10 22:30 7/24/10

  8. Average seismic amplitude at a station on the caldera rim since July 1.

  9. Average seismic amplitude at a station on the caldera rim since July 22.

  10. Average seismic amplitude at a station just west of Pu’u ’Ō’ō since July 1.

  11. Average seismic amplitude at a station just west of Pu’u ’Ō’ō since July 22.
