People have been working on the early prediction of earthquakes since seismometers were invented. You do get clusters of small quakes before a major earthquake, but you get lots more clusters of small quakes that don\'t precede anything. Monitoring ground displacement accurately has become possible in recent years, but that doesn\'t help either.

Global network of seismographic sensors,
for early detection of earthquakes, connected to SDRs
Does SDR (software defined radio)
suitable for transmitting sensor data to a server ?
What is the bandwidth, transfer speed
and how many such devices are already in operation and occupying the bandwidth
Radon, seismographic and other sensors will be installed underground in the gardens of private individuals, powered by solar and the generated seismograms are to be transmitted by radio to the server, without using the Internet.
What range is possible and how much does it cost ?
If anyone has experience with operating
such a remote radio sensor system, I would appreciate your opinion.
If SDR is not suitable for this, then I would appreciate an answer as to what the problems will be.
The sensors will be a few at first, and then a global network of thousands of sensors to detect an incoming earthquake a week in advance and make a safe evacuation of residents.

You don\'t need to fret over this. Global networks are already in place, even in Turkey.

Thank you my friend for your kind reply.
What I mean and work on, is early prediction of earthquakes.
