Saudi Arabia National Seismic Network

Kinemetrics is supplying the Aspen Environmental Monitoring System to monitor seismic activities in the Kingdom of Saudi Arabia.

The network consists of 32 Aspen field stations equipped with STS-2 broadband and SS-1 short-period seismometers. The data is digitized by the Quanterra Q730, a true 24-bit data-logger.

The data is transmitted via spread spectrum transceiver links and leased telephone lines to the Aspen data center located at the King Abdulaziz City for Science and Technology (KACST) in Riyadh. In addition, the King Abdulaziz University in Jeddah sub-network is recording data from seven stations. The Jeddah center is also linked to KACST by a 64kbps digital line (ISDN).

Kinemetrics Antelope, consisting of three SUN SPARCstations, is providing a disk ring buffer of continuous data for 7 days for all channels and for 70 days using online mass storage devices. The Antelope is also providing automatic event detection, arrival picking, event location and magnitude, graphing and reporting within tens of seconds.

The Antelope Seismic Information System (ASIS) is used to process and manage the data using the Center Seismic Studies CSS. 3.0 schema.
