What Is the Difference Between Microzonation and Macrozonation?

AI Thread Summary
Microzonation focuses on assessing specific localized areas within a larger region to identify unique seismic factors that differ from the broader context. In contrast, macrozonation evaluates multiple small regions to determine shared characteristics across those areas. This distinction highlights the granularity of microzonation compared to the broader approach of macrozonation. The discussion clarifies the definitions and applications of both terms in seismic studies. Understanding these differences is crucial for effective seismic risk assessment and planning.

Hey guys, I'm very interested on seismic-related subject, particularly the subject on the title, I've searched all over the internet, but there are many on microzonation but limited information on macrozonation. My question is, what is the difference between the two?

Thanks.David Lee

Microzonation is the process of evaluating a localized zone within a large region for factors particular to that local area that differ from factors assigned to the larger surrounding region as a whole.

"Macrozonation" is the evaluation of a series of small regions in order to identify common factors that exist for all those regions.

Thanks JBA, for your reply. Now I'm cleared. Thanks again!
 
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
