An analysis of data from the March 2009 eruption of Alaskas Redoubt Volcano reveals that harmonic tremors reached high scream frequencies before suddenly stopping at five eruptions, according a University of Washington (UW) press release. Lead author Alicia Hotovec-Ellis, a UW doctoral student in Earth and space sciences, said that the extraordinarily high frequency of this tremor is not easily explained by many of the currently accepted theories. In fact, Redoubts volcanic wail reaches such a pitch it can be heard by human ears.
The pitch that Redoubt got up to was so much higher than any other volcano that weve recorded, and thats kind of pushed the limits of all the models that were out there, Hotovec-Ellis told National Geographic in an interview. Hotovec-Ellis and her colleagues detail their research in two papers published in the Journal of Volcanology and Geothermal Research and Nature Geoscience.
Harmonic tremors are very low frequency waves of varying amplitude caused by interactions between the underground movement of magma and the venting of volcanic gases. These tremors, which may last minutes or days, often precede and usually accompany volcanic eruptions.

“Volcanoes scream before erupting”
So does Michele Obama.
So did Larry Sinclair.
“The hills are alive with the sound of music!”

My grandma had a teakettle like that...
You would too if you knew you were about to shoot a bunch of hot lava out of your hole.
Eerily familiar to the morning after Fiesta Burrito Night at El Mariachi.
The sound of screaming is all of the thetans escaping the volcanos due to evil Xenu dropping them there! Jeez!
They oughta stop dumping stale burritos into Popocatepetl’s crater, in that case . . .
