Dear Ehsan,

To my observation I am only aware about post-predictions. Means detection, yes - but after the event occured. I suggest to check the work from Norbert Jakowski and co-workers, from the (German) DLR Institute for Communication and Navigation.

With best regard, ALEX

Alexander Rudloff Thanks dear

Not that I know of. A useful prediction of an earthquake means stating 1. magnitude, 2. location, and 3. time, in advance of the earthquake's occurrence, together with stating uncertainties on all three of those quantities. A successful prediction method means making such predictions multiple times and demonstrating that the method does better than random guesses. This has not been done.

Oleg I. Berngardt Thanks a lot

Jeffrey J. Love Thanks alot

On the basis of one parameter like TEC, we can not say that an anomaly has been detected due to earthquakes. But at this time, most of the studies on TEC anomaly have been analyzed by retrospective analysis.

Hi Everyone

An answer to this question could be found on discussion about nature of EQs :

Thanks dear

A successful earthquake prediction method, be it by an ionospheric precursor or otherwise, would include magnitude, time, and location, and it would have been shown to provide multiple predictions better results than simply random guesses. This has not been done.

We have analysed daily TEC variation and monitored day by day and presented this paper in a conference ( Investigation of seismic ionospheric anomalies occurred in Turkey during first half of 2019 ).

thank you Mustafa Ulukavak

Mustafa,

You may be interested to read a manuscript 'Single-frequency GPS positioning performance Around the time of the Chilean 2010 earthquake', available at no charge at: Article Single-frequency GPS positioning performance Around the time...

Dear Ehan,

You have gotten very good responses before… To the post of Jeffrey J. Love can be attached the next: Only one case can be accepted the ionosphere TEC for the earthquake precursor if can be attached to it (it can be verified with other precursors… Last six 12 months I have made several successful earthquakes forecasting you are welcome to the next discussion: https://www.researchgate.net/post/Exists_the_next_situation_when_an_outsider_researcher_who_has_achieved_a_very_encouraging_result_in_earthquake_forecasting_is_not_supported

There is mentioned such a method in the discussion which may be useful for you…

Mustafa, here's an article on forecasting based on solar wind density. Best regards, Vyacheslav Mikhailovich

Dear All. The response you can find at next link: https://www.researchgate.net/post/Exists-the-next-situation-when-an-outsider-researcher-who-has-achieved-a-very-encouraging-result-in-earthquake-forecasting-is-not-supported The first and probably the most difficult step is solved! That would be followed by a lot of work... I hope my wife is not right: No one will be properly interested in my work... Regards, Laszlo
