# geo: low frequency sounds that resemble the shape of the tornillo seismic waves

AA << characterize and interpret a new type of infrasound signal originating from the summit of Volcán Cotopaxi (Ecuador) >>

<< This infrasound waveform is a slowly decaying sinusoid with exceptional low‐frequency (..) and high quality factor (..) and resembles the shape of tornillo seismic waveforms. >>
