Infrasound Detection Capability in Southeast Asia
Abstract
The Singapore Infrasound Array, located within 4,000 kilometers of approximately 750 active or potentially active volcanoes, can detect infrasound signals from a variety of sources and has recorded recent events from regional volcanoes and meteors. Previous studies quantified improvement in infrasound detection capabilities from the addition of the Singapore infrasound station. Several meteors in the Indo-Pacific were recorded by regional infrasound arrays in late 2015 and early 2016. In addition to meteor signals, there was a small eruption at Marapi Volcano in Western Sumatra on November 14, 2015 that was recorded on the local seismic network as well as the Singapore Infrasound Array. Long-term site characteristics have also been studied to identify persistent anthropogenic noise sources. The ground truth events and ambient noise studies can be used to assess and refine previous infrasound detection capability models as well as quantify site-specific variability in the detection capabilities for volcanic activity.
