AB: A new multi-parameter monitoring system has been installed this year on Krakatau island volcano in Indonesia. The two main objectives are: (i) To improve early warning procedures for volcanic risk in the Sunda Strait and adjacent densely populated areas of South Sumatra and West Java. (ii) To achieve a better understanding of dynamic processes inside the volcano and of external forcings that may influence the activity of Anak Krakatau. The system is designed for long-term continuous monitoring of various geophysical and environmental parameters such as: seismic signals, electromagnetic fields, deformation, ground temperature, meteorological parameters, sea-level and chemical and physical parameters of fumarolic gases. A digital camera allows for visual control of volcanic activity. Installations on the edifice of Anak Krakatau itself consist of three sites in a triangular setting around the volcanic cone. Each site is equipped with a seismometer, either short period or broad-band, differential GPS and ground temperature sensors, forming the backbone of the system. All measuring sites are connected by WLAN. The data acquisition center is located on Java and receives the data streams via radio links. Additional to the permanent installations a network of nine temporary seismic stations is set up in the Sunda Strait region. This paper gives an overview of the installations on the Krakatau island group. We would like to encourage discussion on the difficulties and possibilities of such monitoring systems on island volcanoes.
