ABSTRACT: In situ AE monitoring is one of the useful methods to predict rock failure such as earthquakes and rock slope collapses. The commonly used AE sensors, however, are hard to mount tightly and keep stable. We propose a new type of AE monitoring system, which is easy to install and enable us to continuously monitoring for a long time. The sensor is consist of a self-made hydrophone covered with water-filled stainless pipe. We confirmed its practicality in preliminary in situ measurements, and then calibrated this system. It should be also noted that our system is preferable in economical sense.
