Summary

[edit]
Description

Vampire Mountain Rockslides, New Zealand, 2008

Vampire mountain spectra.

Sound of the Earth's vibration

Two consecutive rockslide events, seismic data:

Monday 7 January 2349 (NZDT) - 100,000 m3 collapse - 2.4 equivalent earthquake magnitude.

Sunday 13 January 0923 (NZDT) - 50,000 m3 collapse - 2.5 equivalent earthquake magnitude.

Audio is seismic ground motion data sped up 20x (to make the pitch audible) then slowed again by 50% (without changing the pitch).

Each of the two horizontal components of ground motion is independent in stereo, while the vertical component is split across channels.
