Portable Infrasound Arrays

The portable infrasound arrays designed by ISLA consist of a single 6-channel digitizer, four Chaparral Physics Model 2 sensors, and a wind speed/direction sensor. Power is supplied by portable solar panels and batteries. This set of equipment can be easily transported and deployed in a matter of hours, rather than the days and weeks of construction needed for a permanent installation. This makes the portable system ideal for short-notice or one-shot deployments.

These sensors have been used for studies at Kilauea Volcano, the study of infrasound generated by surf at Polihale and Makalawena and Moorea, observations of missile launches, and possibly Ecuadorian volcanoes.
