The first blog of the day calls for some technology inputs, right?
Well, here goes with the idea that at the concrete base foundation of the bullet trains, there should be triaxial accelerometers giving seismic signals for stopping the system in case of detection of seismic movements likely to culminate into sizeable quakes.
I am sure that the Japanese would have worked on this to a great extent with the recent quake providing ample lessons in context.
A sunk seismic sensor (SSS) as i would like to call it is a triaxial accelerometer that gives an indication of movement in three cardinal axes. A module developed on this basis and applied at 1 km distance would give a network of sensors along the track for prediction of seismic movement.
Since such modules are available from Rs. 249 to USD 1570 , the Institute of Seismological Research, set up in 2006 in Gujarat can work on a data logging system collecting subterranean inputs from commercial sunk seismic sensors in the foundations that can be made compulsory for buildings above 10 floors. The standardization routine and the minimum acceptable output integrity from such sensors to make a cogent warning system will have great utility as the high speed rail network expands to other seismologically sensitive zones in India, not that we have forgotten the quake of Kutch that could be felt distinctly by me at the Temple of Panduranga in Pandharpur!
Of course it is possible to look at competing technologies for the sunk seismic sensor like those given the micro electro-optical gyroscopes.
The ideation around building such a sensor network by setting minimum standards for data logging and data transmission to aid earthquake early warning systems and separating it from other basic utilities that such sunk seismic sensors can be used for is as complex as the internet routing problem and one can gauge it by the images below -
But it will be a worth objective for a Seismological Research Institute and what a way for it to contribute to the progress of a a high speed rail network in the nation by reducing the cost to increase proliferation of
