The sound of the earthquake and its aftershocks are being captured by the LIDO system, equipped with hydrophones that record, real time and through the Internet, sounds the seabed. The operation is as follows: you get an automatic recording of acoustic events detected and the sources identified and classified according to whether biological or anthropogenic origin. The system allows simultaneous listening to what happens at different points of observation.
March 11, at 1445 hours (local time in Japan), LIDO system detected and recorded acoustically undersea earthquake observatories JAMSTEC agency, located off the coast of Kushiro and Hatsushima. The recording is available through the project website LIDO, within the 'Sound Library' (paragraph Earthquakes, which contains the earthquake and two aftershocks of the seismic event recorded from two observatories in Japanese).
