Aims

The aim of the IMEEMS project is to understand the mechanism of the strombolian eruptions, and the velocity structure of Erebus Volcano. The present methods are telemetry recordings at Scott Base of seismic, infrasonic, and video data from the volcano, over as great a part of the year as possible.

This season a pilot seismic refraction survey was made on the summit cone, and infrared temperatures of the crater wails and lava lake were measured, paralleled by short term measurements of volcanic gas output, and petrology of the lava being erupted, made by international groups of cooperating scientists from USA. NZ. Italy, Japan, and France. The Windless Bight Infrasonic Array ceased operation on 3/1/90, and RTG was returned to NSF.
