Cronos Large Structure Seismic Recording System


Cronos Seismic Recording System

Cronos consists of several 24-bit NetDAS accelerographs interconnected via the Local Area Network (LAN) to record large earthquakes or seismic events. Cronos is building code compliant and satisfies the requirement for seismic recorders with common timing and triggering. By employing a LAN (as opposed to costly analog cables) greater flexibility in communications, access and maintenance is achieved. The Master NetDAS serves time to all other units. When the LAN is connected to an Internet router, Cronos can be maintained and earthquake data retrieved without site visitations resulting in significant cost savings.
