Automatic interval recording of volcanic clouds at Mt. Mayon, Philippines started in June 2003 as joint work of PHILOVOLCS and the Kagoshima University group, and evolved into a real time monitoring system accessible from Quezon and Kogoshima in April 2004. In this system, a conventional visible camera is used in tandem with a near-infrared camera, which is less sensitive to atmospheric haze and able to detect hot anomalies. It is intended to eventually provide live access to imagery of the volcanic cloud on the World Wide Web/ The necessity of the ground-based system in conjunction with satellite-based volcanic cloud from the Mayon eruptions of 29 February 2000. The performance of the system until November 2006 is reported including the summer 2006 eruptions with lava flows from the summit crater.
