Happy 6th Birthday Halema'uma'u Eruption!

Today the March 19, 2008 eruption at Halema'uma'u turns 6! The eruption in the Halema'uma'u crater began with a small explosive event, and continues today with a beautiful lava lake. In honor of this birthday we at the lab have put together a sound file of 24 hrs of infrasound data mapped into the audible range for your listening pleasure (3/18/14 19:00UTC - 3/19/14 19:00 UTC).

Technical information: These data were recorded by a C50a ~ 7 km from the vent. The data were then bandpass filtered between 0.3 to 10 Hz before being sped up ~1,000x to map into the audible range. The above image is the result of our automated processes (still in development at this time) for the same time period.  

Here at the lab we love to check in on the volcano, and HVO has an amazing array of products that help us keep up to date on what is happening. At the time of writing this is the image from the webcam at HVO:

The image used for the track is also the overlook thermal camera image at time of writing. There is also currently a deflationary event going on at the summit according to the daily eruption update.

Happy Birthday Halema'uma'u eruption and thank you!
