Popocatépetl Volcano Temporary Deployment, 2017-2018

A temporary seismo-acoustic station (ATLI) was deployed from September 2017 to June 2018 at Atlimeyaya (Puebla, Mexico). This site was chosen in order to determine the value of regional infrasound stations for observing eruptive activity from Popocatépetl volcano, 15.8 km to the west-northwest. The station’s infrasound component used four Hyperion IFS-3111 sensors to form a triangular array (aperture ~50 m), with a central element. Each sensor had a high-frequency shroud, with sensitivity set to record pressures ±500 Pa on scale (1,000 Pa full-scale range). The vertical and radial components from a broadband seismometer (Nanometrics 120-s Trillium Compact Posthole), co-located with the central infrasound sensor, were also recorded. All sensors had a flat response from ∼0.01 to 100 Hz. A 24-bit REF TEK 130S digitizer recorded the data at 200 samples per second. Logistical and technical challenges led to discontinuous recording periods for each channel. All channels were in full operation from 27 October to 6 December 2017. Please see Matoza et al. (2019) for further details, and as a citation when using this data.
