I’m interested, but I’m sceptical…
Have a look at this EQ that occurred at Te Anau this morning. It was magnitude 4 at 7 km depth and the recorder is on Banks Peninsula, 457 km away. It’s typical of a great EQ that may occur on the Alpine Fault, only 1,000 or more times smaller.
Most of the energy occurred in the S waves which arrived 47s after the P waves. Assuming we had an efficient alarm system and we got 47 s warning, would that be long enough to do anything?
Living through the thousands of EQs in ChCh in 2010 and 2011, we became adept at sensing the P waves and bracing for the S waves. We didn’t need an instrument for this. There is no sensation quite like the feeling of dread that engulfs you as an earthquake evolves. How big will this be? How can my house stand up to this shaking? Is everybody safe? When will it stop? The last thing you’d think of is going to the computer to look at what the RS says is happening.
So, good luck with your project. You’re welcome to use data from my 2 RS1Ds and Boom, though the practical difficulties of getting a hold of the data in enough time for them to be useful seem overwhelming. I’ll be interested in the results.
