Satellite data show electromagnetic anomalies 19 days before Turkey earthquake

"My cat walked across the keyboard right before the large earthquake" is not statistically significant.

So I read papers like this one as hopeless fishing expeditions. But if the fishing expedition turns up with a good catch anyway, people will look into it more. Unfortunately I'm not versed enough to asses their catch. Will wait for a geologist friend for context.

Piezoelectricity is one of the proposed mechanisms that might explain both earthquake lights and animal behavior changes minutes or hours before the actual shocks start.

I don't know whether satellites are ideal or are sensitive enough (because of their distance from the ground) for this kind of earthquake prediction but over the years there have been significant numbers of terrestrially-bound observations of electrical/electromagnetic disturbances occurring before a quake happens to suggest the phenomenon ought to be fully investigated.

These EM anomalies have been the subject of a news report in an earlier HN story and I made a suggestion then that until the science was fully established that the Amateur Radio Service could be of possible assistance.

Amateur radio operators could perhaps establish a worldwide network to monitor and or detect changes in the EM field on, say, an ultra low frequency band (below the AM broadcast band) as it's likely the most suitable. I'd envisage Amateurs operating a network of CW TXes and signature changes in their carrier signals would act as the early warnings.

This could be done as a separate Amateur operation (national operations—RSGB, ARRL, WIA, etc. and or through the IARU), or in conjunction with various government agencies, IPS (Ionospheric Prediction Services), etc.

The advantage of using the Amateur Service or including it with government operations (which at the outset would be small) is that many more monitoring points could be established quickly. Moreover, given the science is not well established, it's unlikely governments would fund a large network early on. That's where Amateurs come in, by contrast, the cost of establishing an Amateur network would be minimal and would grow organically (as Amateurs are inherently flexible).

How do you trigger "The Alarm" for a given area? How much of a guard band do you put around the event and what happens when you have false positives? Do you call everyone back to the region and say sorry it was a false alarm, only for it to trigger a week later! Would not want to be the one calling the shots on this.

It also seems like a good technology to throw into a movie plot - Super Mega Quake... starring Dwyane Johnson.
