Performance Analysis of Infrasound Sensors at the Pentagon-Triangle Array, Kailua-Kona, HI

This technical workshop, held from November 12-15, 2001, focuses on the performance assessment of the Pentagon-Triangle infrasound array in Kailua-Kona, Hawaii, presented by Charles R. Wilson and John V. Olson from the Geophysical Institute, University of Alaska. The workshop examines impulse response data of various sensor configurations, analyzing the influence of missing sensors on data collection and interpretation. The findings contribute to improving the understanding of infrasound detection capabilities and the operational reliability of the sensor array.
