Quest for Quakes sought to create brand new algorithms to uniquely identify the electromagnetic signals that may precede an earthquake. See how crowdsourcing shook things up.

The connection between certain types of electromagnetic signals and earthquakes is still debated. NASA and the Quakefinder team wanted to develop new computer processing approaches that can search terabytes of data and identify specific types of electromagnetic signals that may precede earthquakes.

Overview

The primary objective of the project was to develop a software algorithm that can uniquely identify the electromagnetic pulses that may precede an earthquake by days to weeks. The algorithm would need to successfully learn how to distinguish between false-positive signals – from sources like lightning – and those originating from from the Earth’s crust.

3 TB of data including known/identified quakes to help ‘train’ algorithms, and many data-sets with hidden quakes to test/validate algorithms were provided to the competitors.

Solution

At the end of the project the top 6 contestants identified between 1-7 earthquakes with statistically significant scores. Ultimately Quakefinder hopes to incorporate the best features of these and other external algorithms now in development. These combined and tested algorithms will become part of their daily search for earthquakes using data from all our 165 instrument sites in California and international locations.
