Earthquakes, Circles and Spheres

Estimating distance and locating epicentre with the help of a little geometric trick.

Generally P-wave (pressure) is horizontal shaking, S-wave (shear) vertical. S is usually stronger and takes about 6x the time to arrive as the P. Distance in km is approx. 6x time between these in seconds.

It has been observed that major seismic events may be preceded by anomalies in natural radio signals, notably those <20kHz (the ELF/VLF frequency bands).

The aim of this project is to develop inexpensive hardware and software capable of capture and analysis of radio and seismic data. Effectively Internet of Things (IoT), better still, Web of Things (WoT) subsystems. That’s the easy bit.

The hard part is the idea of providing useful earthquake prediction.

The key, novel, intuition here is that Deep Learning techniques may expose patterns in the wildly noisy signals of the Earth. We’ll see.

I’m Danny Ayers, usually a (Semantic) Web developer/consultant. But living in a seismically active part of northern Italy led me toward this stuff.

I’m in the process of setting up a site to place all my material. That’ll be at hyperdata.it
