Abstract
PURPOSE:To reproduce earthquake data in a storage part even when the building of an observation station broken owing to a large earthquake of if a communication cable is disconnected by burying a measurement part formed by uniting the measurement storage part with a sensor in the ground. CONSTITUTION:The measurement part 2 of the small-sized seismometer to be buried in the ground and a processing recording part 6 to be installed on the ground are connected by a cable 7. The measurement part 2 is constituted by uniting an earthquake detection sensor 3 with a measurement storage part 4, which is provided with a conversion part 11 with an analog-digital converter of >=16-bit constitution, a digital filter part 12 with >=16-bit accuracy, a storage part 13 backed up by a battery, a control part 14, and a power source part 15 while a processing recording part 6 is provided with a recording part, a timer part, a control part, and a power source part. Consequently, data are left in the storage part even if the communication cable, etc. are disconnected or broken owing to a large earthquake.
