Characterization of the Infrasound Field in the Central Pacific

Abstract

This document reviews the results of three years of infrasound recording and analysis at the Infrasound Laboratory (ISLA) of the University of Hawaii. ISLA is responsible for the operation and maintenance of infrasound station I59US, Kona, Hawaii. I59US entered into operations in July 2000 and was certified into the International Monitoring System (IMS) of the Comprehensive Nuclear-Test Ban Treaty (CTBT) in December 2001. The array site is in a tropical rainforest on the slopes of Hualalai Volcano, Hawaii Island, Hawaii. Per IMS specifications at the time of the installation, the array consists of four microphones arranged as a triangle with a 2 km baseline and a central element. This site is well-forested with 20-30 m ohia trees, 2-3 m tree ferns, and ground ferns, which form a multilayered wind barrier.
