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, Redoubt’s 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 we’ve recorded, and that’s 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. …
