  1. 2008 eruption of Okmok Larsen et al. (2009) EOS

  2. Okmok eruption seismicity OKWE RSAM amplitude (arb. units) 7/13 7/20 7/27 8/03 8/10 8/17 strong tremor

  3. VLP tremor during Okmok eruption VLP tremor has been previously reported by De Lauro et al. (2005) at Stromboli

  4. Stations used for tremor analysis

  5. Comparison of Amplitude Spectra

  6. OKSOz-OKFGz inter-station times

  7. Histograms of 10 inter-station times

  8. Tremor located NNW of Cone D Haney (2010) JGR, in press

  9. caldera rim new cone Cone D north south

  10. Similar phase velocity for Love waves, so a similar inter-station time expected
