Super Typhoon Haiyan

Aloha! It has sure been busy at the lab this year, but something like Haiyan doesn't happen every day, so here I am! I have just a quick post today with a few figures and a new track. Enjoy!

The CTBTO IMS station I39PW is located on the island of Babeldaob in Palau. Super Typhoon Haiyan ran over the northern most state of Palau, Kayangel island on 06 November 2013 UTC. The infrasound station I39PW recorded the approach, and part of the typhoon before losing power late in the day UTC.

 Taken at 13:00 UTC 07/11/2013 by the geostationary satellites of JMA and EUMETSAT.

Spectrogram and array processing results from I39PW created by ISLA.

I recommend also listening to the infrasound data sped up ~ 2000x so it is in the audio range while viewing the figures. The following track is around 10 hrs of data covering the ramp up of the storm as well as the storm passing over, up until the station lost power.



Super Typhoon Haiyan was a category 5 when it slammed into Palau. According to an article on gizmodo the storm has broken the intensity scale by 0.1 when it registered 8.1 out of 8. It is beautiful and dangerous. The lab's thoughts are with the people of the Philippines.

Welcome to the world of infrasound! Volcanoes, severe weather, tsunamis, meteors, earthquakes, and all large things that blow up can produce inaudible atmospheric sound, which can be recorded by a global microphone network. In this clip, Dr. Milton Garces introduces low-frequency acoustics as background to surf infrasound studies.
