This topic has been open for a wide range of researchers here and outside of RG, as open access to write and read comments related.
I encourage researchers with a deterministic view on earthquake nature for being proactive by trying to use resources of this space as much as possible in a way of understanding this phenomena by challenging their forecast models through forecast tests.
On forecast, I would like to find the method, data and time window for forecast, with magnitude range and probability of occurence. If the location of future event is possible, please specify. It's a test, and additional option to write about our successful forecasts and our correct models.
Also, please be concise, as possible.
In addition, I suggest to make references to own research, or other sources, for keeping the transparency on sensitive questions such as autor rights, originality and other aspect. For this, in case of not published yet ideas, I suggest to publish and come down in the comments with reference to official open to public source - article.
N.B. Regarding the forecasts based on statistical methods, and random nature of the EQ phenomenon view, are also welcomed.
Sincerely,
Sandu I.

As it was mentioned, for remains forecasted time interval could appear M7*(6.0+), and it occurrs - today 14.04.2020 a 6.0 EQ. EMSC link, just on time! Again success
https://www.emsc-csem.org/Earthquake/earthquake.php?id=847842
Rehards,
Sandu
NB. Ok, first estimation of EMSC on event magnitude, provide 6.0, after 3 hours on EQ occurence the magnitude correction is for 6.1
General notice for comming week, or EQ forecast time-window 16.04.-23.04.2020.
The M7*(6.0+) probability of occurence is 90%. Additional info will come soon. Keep global.
Regards,
Sandu
If we consider EQ as a deterministic proces we have to define prediction. When the df contains time of occurrence then it can be obtained only for periodic (or quasiperiodic ) processes or if there are clearly and strictly defined precursors. As far as I know we don't have them so we have to consider EQ as stochastic events and realise prediction in probabilistic way.
Regarding previous posts on EQ forecast for 16.04-23.04.2020 that expectation for M7*(6.0+) are up to 90%
We got 2 events today, which fit this magnitude category, please follow the EMSC links.
https://www.emsc-csem.org/Earthquake/earthquake.php?id=848555
For second, waiting corrections, because the 6 in magnitude is first estime from EMSC. Anyway, both fits also location and time of their occurence if to follow Earth-Sun-Moon gravity interaction model, which I am develloping and support in my works.
Also, I can add here, these 2 are the first birds on comming event for next day M7*(6.0+) so, the activity is keeping rise.
Be safe. Regards
Sandu
N.B. the 2nd EQ was estimated by EMSC by 5.9 in hour later. In same way, I could mention that 6.0 in magnitude could be fine for Myanmar region, according to gravity anomaly record made and registered in Europe. Here, the M7*(6.0) was estimate the EQ in 2018-01-11 18:26, from Myanmar epicenter area (by EMSC), with simmilar gravity anomaly made 2A=700 nm/s^2. Today event have 2A=800 nm/s^s even more than for 6 value of magnitude. Anyway, more seismic impact should expect for comming days.
Wacław M. Zuberek
Thank you for your comments, here.
Yes, your remark is OK, and define well the existin 2 positions on earthquake interpretations.
If we know the real causes then we can build a deterministic forecast model, if not then use stochastic approximations, as it is used to do for this moment. This means that seismology have not clear image of all seismogenic process yet.
Regards,
Sandu
Dear Colleagues
As I have mentioned above, that on remained time window forecast 16.04-23.04.2020 we should expect extra M7*(6.0+) and bigger than 2 early birds of M7*(6.0) which were also forecasted. Location suit wel Earth-Sun-Moon gravity interaction model supported and develloped in my works so, location can be forecasted! Anyway energy and time was forecasted successfuly here!
EMSC report today 18.04.2020 6.7 magnitude as firs estimation https://www.emsc-csem.org/Earthquake/earthquake.php?id=849227
Looking for updates in magnitude corrections
Regards,
Sandu
Regarding the magnitude corrections. EMSC made shift from 6.7 to 6.6, but let's have a view of this seismic area from gravity records. Almost, with same epicenter, EMSC reported 6.5 for event 23.06.2015 12:18, which made gravity anomaly record in Europe 2A1=550 nm/s^2. Today event made 2A2=1100 nm/s^2. This made magnitude diference M2-M1=Log(A2/A1)=Log(2)=0.3 so, finaly, M2=6.5+0.3=6.8
Magnitude should be 6.8

Notice, on useful link EMSC report https://www.emsc-csem.org/Earthquake/earthquake.php?id=851198
Regarding the magnitude, EMSC, made correction for todays EQ from 6.3 to 6.2.
Let have a look at seismic area, and find similar events estimated by EMSC. So, here, the 09.02.2020 06:04 EQ with M7*(6.2) can be found https://www.emsc-csem.org/Earthquake/earthquake.php?id=828355
Let have a look at their gravity impact or vertical acceleration component seismic records for Europe. Today EQ made anomaly of 2A(1)=1800, but 09.02.2020 event, made only 2A(2)=800 nm/s^2. Their difference is estimated by Log(A(1)/A(2))=Log(1800/800)=0.3 so, today event is by 0.3 value of magnitude greather than 6.2 event in February 2020 (same area).
Instead of estimated 6.2, should be 6.5!
Regards
Sandu
Colleagues,
It remains 24 hours from forecasted time interval - up 26.04.2020. We should expect M7*(6.0+).
Dear All,
Regarding last notice, for remained time interval of 24 hours, the expected M7* didn't occurs. It's normal, seems need more time for energy release. Let's make assumption for next week 29.04-05.05.2020, for M7*.
Corrections will come soon.

Sandu I.
Dear All,
Just in time!
After 30 minutes writing my above notice regarding on delay of EQ occurece, and possible postpone for next comming week, the EMSC reported for M7*(6.6) EQ in Cuba region. Successful!

Regards
Sandu
Notice on magnitude corrections
EMSC change the magnitude of EQ from 6.6 to 4.6 https://www.emsc-csem.org/Earthquake/earthquake.php?id=852360
Regarding this values, on gravity observations, event impact is less than for M6*(5.0).
This means that M7* is active and expected to occur in specified time-window.
Regards,
Sandu
As we expect for 29.04 to 05.05.2020 to have M7*(6.0+) we just receive a report link of EMSC of M7*(6.5) EQ, for Greece area.

5.9 EQ today, 03.05.2020, reported by EMSC
https://www.emsc-csem.org/Earthquake/earthquake.php?id=853635
Seems to be underestimated if to compare the historical reports on seismic activity of this region (Japan) - we found 6.1 EQ EMSC magnitude on 13.07.2019 which made gravity anomaly for europe 2A=1000nm/s^2. Today, EQ, made 2A=7000nm/s^2. Their difference is log(7)=0.8 this means, today EQ is 6.8 if to consider previous event precise estimated. But, as we see errors persist and can not be neglected, which induce uncertainties.

Notice, about estimated magnitude values of EQ's in Greece, yesterday 18.05.2020
EMSC provide M1=5.3 and M2=5.4 for EQ's
https://www.emsc-csem.org/Earthquake/earthquake.php?id=858980
The only difference between these 2 events could be seen on gravity anomaly records at same gravity station, for 1 EQ 2A=600, 2 EQ 2A=3000 nm/s^2. Log(A2/A1)=Log(3000/600)=Log(5)=0.7=M2-M1. The fact, that difference between EQs is 0.7 magnitude is not reflected by EMSC. EMSC estimate 0.1 magnitude difference, which is wrong.
Regards,
Sandu
Notice. Regarding EMSC magnitudes for 2 EQ in Greece, yesterday, 19.05.2020
As was mentioned above, 4 hours ago, here, the difference was 0.1 as 5.3 and 5.4. Now, is 5.3 and 5.8, after review of EMSC. In fact, the real difference is 0.7 based on acceleration amplitudes recorded at same gravity stations. Anyway, corrections has been made by EMSC so, looks better the seismic report.

Dear Colleagues,
How it was expected for time window 16.05-23.05.2020, we have M7*(6.1) EQ report from EMSC

Forecast - successful!
From gravity records anomalies, the acceleration values amplitude are 2600nm/s^2, and from same region, to compare M7*(6.0) EQ, reported by EMSC, 2018.06.30 is 600nm/s^2. This fact, suggests for Log(2600/600)=Log(4.3)=0.5 difference, or 6.5 for today event.
Preliminary estimations of EMSC is 6.1, now
Looking for corrections

Hi all,
Regarding today global seismic activity, EMSC reports 5.8 magnitude for an EQ, by this link: https://www.emsc-csem.org/Earthquake/earthquake.php?id=867018
From EMSC history seismic records of this area, we found similar EQ M7*(6.0) for 2018.04.19
Both, 2018 and today 2020 event have same gravity anomaly magnitude recorded by same European gravity station 500nm/s^2. This means, the magnitude should be same : or 5.8 or 6.0
If check additional event for this area, on 2015.10.23 with M7*(6.0) we found gravity anomaly 400 nm/s^2. So for certain it should be M7*(6.0) today.
Anyway..
Regards,

Impressive but utterly meaningless! On average more than 11 earthquakes of magnitude 6.0 or greater occur per month, globally, anyway.
To Kin-Yip @
Thank you for yor (simmilar) comment here.
Yes, statistics, and again statistics, is used in discussions. But, in fact, the cause of this are in the statistics methodology roots, understanding and use.
By the way, you claim that (on average) some number of earthquake occurs monthly, globally, anyway - here, I will agree and disagree (on same time). First, it is about incomplete sentence, you build, which is not totally clear, and ask to be compleded by additional questions:
1. Have you done the investigation by yourself on computing mean values of EQ/month ? If yes, go next question, if No -specify reference of this investigation (all details can be found in the relevant authors paper).
2. Data used, especially, time interval. Do you try to use different values for time interval as observation period? If yes, please add the missing conclusions here, if No, advice to do. This is because of non homogenic (liniar) distribution of EQ occurence in time, so you will have each time different value for EQ/ month. So, the main conclusion here is - using this ratio is useless because it is not appropriate with EQ phenomena, and results are strongly related by the used data. And we know, the ratio - as a law, should go to some constancy on behaviour with some standard fixed appropriate deviations. For this ratio, I can suggest you from my experience, and hundreds of scientist from the field that ratio is not costant value yet.
3. In order to have EQ/month, this means you use time intervals more than month, like years... how about weeks?
Can you find in my time window that I refer to the month? I check, once more, between hundreds of forecasts 99.9% are related to weeks, and with more than 95% confidence all of them were successful. Can you find to someone of scientists simmilar results? Or maybe, simmilar statistics related to weeks?
I suppose no. And this is important.
To say, according annual data, that on average 11 EQ per year occurs, is not simmilar with occurence of 1 EQ per month, because last sentence is stronger in confidence. Can you confirm or not regarding a month time interval if an EQ with M7*(6.0+) will occur on specific month? Have you tried? I think it is more difficult, than to resume for a year. For a year, seems to have more stable results, but again it differs from year to year. So, unstable!
If, it is difficult for a month, here, I will not continue questions for weeks forecast. On classic, and modern interpretations through statistics of seismic activity, to forecast for the weeks it is impossible - at the moment, and for comming centuries.
This was to explain the difference, between, clasic, modern way of thinking by statistics an methods used by me. I have no needs to know seismic activity about 100 years ago, or 1000 years ago, to tell about seismic activity for next week. But I do.
Do you still think it is usless to successful forecast weekly the M7* ? How about the classic resources allowed by statistics, which can't forecast EQ for month even?
I suggest - totally usless, then.
At the end, what we have ?
This is open question for everyone..
Regards,
Sandu
I can remember the era in early 1980s when a phalanx of Californian practitioners in astrology, all very knowledgeable with USGS earthquake statistics, used to make far more impressive and successful," but equally meaningless, earthquake predictions/forecasts" in print media than yours. With waning readership, they eventually stopped forecasting and went into some other nebulous trades.
To Kin-Yip @
Thank you for your valorous detailed answer.
Can I ask for a favor, please specify several works of which you make reference for. On the 80s era many interesting events occurs, even the forecast phenomena has been observed for seismic activity..
Thank you in advance.
Regards,
Sandu
If I were you, I wouldn't waste precious time on it. You have an academic/research future ahead of you, and you can hardly afford doing what you have been doing here.
"On the 80s era many interesting events occurs, even the forecast phenomena has been observed for seismic activity.." ? You must have been sleeping throughout all these years. No reputable, prestigious international academic journals had ever reported credible earthquake precursors in 1980s. Had someone been audacious enough to apply for an earthquake prediction research grants in the United States of America, for example, he or she would have been considered crazy, mentally deranged, and certainly unfit to work as a scientist.
Stop communicating with me. This is absolutely the very last reply I will ever care to write to you.

M6.9 https://www.emsc-csem.org/Earthquake/earthquake.php?id=886534
The time difference beetwen OT of the events are 6 min, which, in fact is too small window for distinguish such a big events and should be considered as one event. The depth on 10, and 30 km made formal difference again so, using attenuation formula - the secon event seems to be greather and estimate as 6.9, but here, we have only 1 event, with identical anomaly shape on gravity records in Europe as from the morning Philipine ones M6.6.
As, I have mentioned above, the magnitude there should be 6.8-7.0, same as for Sumatra estimated by EMSC for 18.08.2020.
Lets resume for 18.08.2020.
By EMSC we have 3 EQ 6.6 and 6.8, 6.9

Dear Kin-Yip Chun,
Moving from China in Canada, somewhat you have forgotten natal place: what do you think about the next place:
https://www.youtube.com/watch?v=3Ze6nzaO-rE
and:
'Prediction efforts are still developing and as technology advances. The Chinese Earthquake Administration (CEA) takes great care in gathering data in all provinces and working to ensure the safety of citizens and visitors. In fact, in 1975 many lives were saved through early evacuation of the Haicheng area after seismologists reported activity the day before a 7.3 magnitude earthquake rocked the area. '

At the next discussion you will see that perhaps you have given wrong advice to Sandu:

Dear Dr. Laszlo,
I advise Dr. Sandu not to waste any more of his time on what he has been doing: he couldn't possibly afford doing so for a young man in academia.
You are right, I did move move from China to Canada in early 1968 when I was very young -- before I had finished my high school. But what has my move to Canada more than 50 years ago anything to do with any issue you want to raise?
Your mention of the 1975 Haicheng earthquake is interesting. The "prediction" was made not by scientists but rather by an "revolutionary leader" with no seismological background whatsoever. The officially announced "scientific basis" for that prediction has long been universally deemed unreliable, unscientific, and of no value. The so-called "success" was a political propaganda. It was preceded by countless false alarms made by real seismologists, resulting in dire economic damages. You should know that if one makes enough random guesses, he/she may get lucky one day. Today, most Chinese seismologists won't be happy talking about the Haicheng earthquake prediction -- for a good reason.
Now, please kindly stop writing to me any more on this subject, Dr. Laszlo.
To Kin-Yip Chun:
Thanx for your valuable comments here. I hope, also, someone will follow your advices in the future. All the best!
OK
