High Resolution Aftershock System Model 160-3

High Resolution Aftershock System Model 160-3 - Introduction

The REF TEK 160-03 is a self-contained, fully integrated Aftershock System providing the customer simple and quick deployment during aftershock emergency mobilization.

The 160-03, 6 channel recorder, contains three major components integrated in one case:

• 24-bit resolution low power ADC with CPU and Lid interconnect boards

• Power Source

• Three component 2 Hz sensors (two horizontals and one vertical) and a triaxial MEMS accelerometer

The self-contained rechargeable battery pack provides power autonomy up to 7 days during continuous data acquisition at 200 sps on three recording channels. For longer power autonomy, the 160-03 Aftershock System battery pack can be charged from an external source (solar power system).

To download recorded data the customer should simply connect a laptop to the 160-03 and data will be automatically off-loaded.

For station operation verification the customer is able to display real-time data acquired by the 160-03 using the iPod Touch connected to the system via wireless (Wi-Fi) communication.

Aftershock study provides practical information for local authorities regarding the post earthquake activity, which is very important in order to conduct the necessary actions for public safety.

Due to a relatively short aftershock activity period, it is critical to provide rapid deployment of emergency personnel to the area in order to minimize the time required to estimate the extent and amplitude of strong shaking from aftershock events.

A dense array of seismic stations consisting of high resolution seismic recorders with short period seismometers and accelerometers is required in order to reduce the time needed to detect an event and provide high resolution maps of ground accelerations across the earthquake region. Therefore, the rapid aftershock mobilization of seismic equipment should comply with the following critical requirements:

• Lightweight and small in size

• Integrated design with minimal or no external peripheral equipment

• Very low power consumption

• Minimal or no field programming

• Easy and quick data download in the field

• Low maintenance

Application
