Infrasound Monitoring System

The infrasound monitoring system employed by EOS was first used to monitor volcanic eruptions from Indonesia. This monitoring system detects low-frequency sound waves, and the data collected will provide information on the location and explosivity of the eruption, allowing our scientists to determine the impact of volcanic ash on air traffic in and around Singapore.

The data from the Infrasound monitoring network contributes to the Tsunami early warning system, as it can detect the sound wave from the tsunami source well before the tsunami waves arrive the coastline.

EOS is currently developing its capacity of Infrasound monitoring in Singapore. The first part of its Infrasound system was installed in Singapore in August, 2013, to monitor distant volcanic eruptions. The station caught the infrasound signal from the Kelut volcano eruption in February, 2014.

This system, which can detect very low frequency sound waves in the air, provides very useful information for the early warning of distant volcano eruptions. The data collected by the Infrasound system provides independent and rapid diagnosis of the location, and the explosivity of an eruption event, before the volcanic ash may influence the air traffic near Singapore.

This system also has potential applications for geothermal exploration and the monitoring of mining activities.

The scientists in EOS are now working closely with other international research institutes on the Infrasound monitoring systems. With close relationships to infrasound experts around the world, we have the ability to install and operate the Infrasound system. EOS also has the capacity to process and analysis the data.
