The computer will be configured to establish a connection link at prescribed time to download the recorded information and then upload it into the mobile phone that will transmit it to the UDSM center as a Simple Message Service (SMS) ( Heaton, (1985), Charny, (January, 10 2005).įigure 2.22.
Wireless link is available to all five Tanzania seismic stations, which are equipped with communication port for easy connections to other systems.To use this option, a normal mobile phone receiver set with and computer will be installed at seismic station to set-up and control a communication link between seismometer recording instrument and the transmitting mobile phone station where the later will be connected to recording computer at UDSM through a second receiving mobile phone. Distribution of each technique is given in the following section: (i) SMS message through Mobile phone operators Three possible techniques can be used to transmit seismic signals to the UDSM center for analysis, which to choose will depend on the financial position of the funding agent and location of the seismic station.

2.2 How to Transmit Seismic Signal to UDSM Center Many remote seismic stations are reachable using mobile phone and are powered using solar panel. Also the Orion system is equipped with magnetic tape recorder for recording seismic data. 2.1 Technical outline of Current Remote Seismic StationĮach seismic station in Tanzania is an Orion Nanometrics Seismological Instruments type, producing a broadband signal that can be transmitted to Global Positioning Satellite System through a built-in Global Positioning System (GPS) antenna. Data to be transmitted will be purely ground motions as recorded from the seismometers.
Basic system for Earthquake Monitoring.įrom Figure 2, recordings from remote seismic stations will be transmitted to the available communication tower and re-transmitted to UDSM center for analysis.
