So, the difference between 8 and 9 is 10 times amplitude and 31.7 times energy. I can take that. Now how accurate is the instrument?
I remember even the US is adjusting the level from 7.5 to 7.8 and some others are saying 7.9. Right there there is a difference of 2 to 3 times. Were they forecasting something that had already happened looking at the damage or they had instruments on the ground around Gorkha and looking at the table or graphs from the instruments?
My feeling is, none of the engineers in the world will be able to exactly say it will not crack at 7R but will crack at 8R for each house they build. Correct me, but earthquake resistance has some part of statistical nature along with deterministic characters.
