What’s shaking? Earthquake detection with submarine cables
- iandanforth 6y ago"To create a robust earthquake monitoring system, researchers need advanced mathematics and data analytics, where advanced computing systems like Google Cloud can be instrumental." Great article with the most tenuous tie-in ever. The authors were probably thinking, "Look at all this great science, and holy cow this is a global sensing device! ... oh wait we work for a corporation we better plug one of its services somehow."
- cosmie 6y agoThis is a really neat trick, and incredibly beneficial if it gets matured to the point of a production-capable alerting system! Question for anyone familiar with this type of work: would nearby submarine traffic be detectable using this technique?
- milesvp 6y agoI was recently talking with someone who manages seismic data, and using fiber optics to collect seismic data is really taking off. The amount of data you get is orders of magnitude more than a traditional station. They had a problem, as custodians of seismic data, of someone trying to give them a new data set that represented 10% of all their historic data. It’s kind of crazy how easy it is to drown in data.
- jimmySixDOF 6y agoI was involved with a job using a Fiber based perimeter fence intrusion detection system back when this was a new thing and the sensitivity was its main problem due to false positives. You needed to rezone and adjust thresholds in zones based on wind direction etc. Still it is a great tech & nice to see it applied at this scale for pure science. BTW my understanding is the idea was first commercialized by oil and gas to discover real-time conditions down a drilling well head.
