Newcomers have little chance of understanding this without my help I'm afraid. So, let me explain TR below.

LS-NORTH SAN FRANCISCO TO TIP OF ALEUTIANS/ 6.4 at S.F./50%.
PR PR DATE CRT.DATE MAG POSSIBLE LOC
Out of critical until 6/19.

TR-FAR NORTHEAST/ 4.6/50%
30MM- means 30 minute pressure, on a six point scale of pain, was a medium minus or 1.

8/5/94 means the day this pressure hit me.

5/20-5/29 means the nine day window in which this quake will or will not occur. Nine days windows are derived by squaring the numbered day, thereafter the pressure, subtracking 4 and adding 4 to the critical date resulting from squaring. Example: say today; 5/28, I get a pressure. Tomorrow is day 1, Friday is day 2, Saturday is day 3, Sunday is day 4....after today's pressure. So, let's take day 4. We square it; 4X4+16 or 16 days from today which will be Friday the 13th...also known at the Critical date. Now we take 4 from the 16 and the earliest this EQ could occur will be no 6/9 Monday. Then we add 4 to 16 and the last day this quake could occur will be on Tuesday; 6/14...for a total of nine days. But because the windows will overlap until we get to the sixth day after the pressure, this EQ will in critical for the next 29 days (5X5=25+4=29). Then there will be three days in which this EQ could not occur. The next window (6X6=36-4=32 days after today) will start four days after the close of that last window. At this point, every nine day window will have increasingly more days between them when this EQ cannot occur. Clear as mud to you, you say? It would be if you wrote it all out on paper. Drove me crazy in the beginning crunching all the numbers, but then in the beginning the quakes came within the first 29 days and that wasn't too hard. Later, I had to write a mini program that would do the caculation and date converisons for me. Now I can put in the date of a quake and the program will come up with the day I should have gotten a pressure for it. Which is exactly what I did for China's big quake and you can read about that under the topic Expect Large World Quake.

+6.2 if Carson, NV or there abouts. Just my quessing where this quake will occur...if it does within this window. Sometimes it's a little more than quessing. I may have had a different and additonal symptom for the TR area.

Okay, hope this helps in understanding the Critical EQ Windows. Please ask questions if you want and I'll try to anwser.
