Thread: Fwd: IRIS DMC Special Event: May 4, 2018, Mw 6.9 earthquake in Hawaii

Started: 2018-05-05 16:43:28
Last activity: 2018-05-06 03:36:40
See attachment for a quickly made sonification of a nearby seismic station
that recorded both the M5.4 and 6.9 sequences, as well as some gliding
sounds. Such sounds could be related to gliding volcanic tremor during or
preceding volcanic eruptions, or could be generated by man-made sources
such as air traffics.

Let me know if you have any further questions. Thanks again.

  • At those frequencies, the "tremor" is from helicopter activity. No gliding
    harmonic tremor has been observed in the current eruption. For what its
    worth, KLUD is closer to the volcanic activity (~2 km distant).

    • Hi Wes:

      Thanks for your email. I was chatting with your colleague Leif Karlstrom
      via another email thread, and he pointed out the same issue (likely
      pointing out by you as well).

      The primary purpose of that video was to show the numerous microearthquakes
      during the recent sequence. The gliding signal was a total surprise and I
      was not sure if it was truly related to volcanic activities or due to air
      traffics (as noted in the original caption). Now that you have confirmed
      it, can we modify the caption as something like this?


      Sonification of a nearby seismic station that recorded both the M5.4 and
      6.9 sequences, as well as some gliding sounds. The gliding sound was
      generated by helicopter activities. No gliding harmonic tremor has been
      observed in the current eruption (Weston Thelen, USGS).

      Of course, if you feel that it is misleading, we could also take off the
      video. Thanks again and look forward to your reply.

      Zhigang

      • That's an interesting video, Zhigang. I agree with the earlier comments
        about gliding. I'm curious why you chose this particular station instead
        of one closer to the source (also which wouldn't be affected by
        helicopters).

          That's an interesting video, Zhigang. I agree with the earlier comments
          about gliding. I'm curious why you chose this particular station instead
          of one closer to the source (also which wouldn't be affected by
          helicopters).

          Hi Wes:

          Thanks for your email. I was chatting with your colleague Leif Karlstrom
          via another email thread, and he pointed out the same issue (likely
          pointing out by you as well).

          The primary purpose of that video was to show the numerous
          microearthquakes during the recent sequence. The gliding signal was a total
          surprise and I was not sure if it was truly related to volcanic activities
          or due to air traffics (as noted in the original caption). Now that you
          have confirmed it, can we modify the caption as something like this?


          Sonification of a nearby seismic station that recorded both the M5.4 and
          6.9 sequences, as well as some gliding sounds. The gliding sound was
          generated by helicopter activities. No gliding harmonic tremor has been
          observed in the current eruption (Weston Thelen, USGS).

          Of course, if you feel that it is misleading, we could also take off the
          video. Thanks again and look forward to your reply.

          At those frequencies, the "tremor" is from helicopter activity. No
          gliding harmonic tremor has been observed in the current eruption. For
          what its worth, KLUD is closer to the volcanic activity (~2 km distant).

          during or preceding volcanic eruptions, or could be generated by man-made
          sources such as air traffics.

          Let me know if you have any further questions. Thanks again.

          Dear colleagues,

          In response to interest in the May 4, 2018, Mw 6.9 earthquake in
          Hawaii, the IRIS DMC has created a Special Event web page that provides
          direct links to and images of data and materials available from IRIS
          programs and preliminary research results from the seismology community.

          We welcome any additional contributions that might be of interest to
          the research community, which can be emailed to
          special-events<at>lists.ds.iris.edu.
