thanks for such a nice video..but i steel did not understand how we convert time-acceleration (earthquake data) to accelration-period (design spectrum)? Becouse earth data comes with time and time converted to period...in this particular transition what formula we use? have any video to explain pls or planig to make such a video? thanks
Nice work but 800m building height is a bit exaggerated. The houses built on the plain are expected to be lower than those built on the rocky ground but the opposite was done in the earthquake zone.
I believe the recorded values were not very accurate at the time being. Later some sources corrected the pga. The earthquake reached 0.6 g but never 1.9 g.
@CHRISTIAN JUNIARTO as far as I know, the early calculations were not normalized properly. The reason is partially political. The emergency units were not as experienced and organized as required during the early days of the disaster, so the government, instead of doing proper investigations, decided to state that the Maras earthquake was the largest earthquake of this century by using false datasets. In other words, the falsely measured numbers are used for political statements to put the blame of 50k casualties on nature itself.
@CHRISTIAN JUNIARTO it is important to mention that most buildings in the zone were retroactively legalized despite the fact that they had been disregarding essential construction codes. This is also another reason why the pga values were shown so high.

Here this pga are bed rock pga or surface pga??

I live in a 14 store building over ground with Vs30=200 m/s
Am I safe or should I go live elsewhere?
