[CEUS-earthquake-hazards] Article on Central U.S. Earthquake hazard by expert panel

[Wang, Zhenming]

Rus,

As I know of, the intensity scale for the 1956 map is the same for current map (the conversion table).
Relationship between the intensity and peak ground acceleration (PRCNS, 2001)
Peak ground acceleration (g) \0.05  0.05  0.10-0.15  0.15-0.20  0.20-0.30  0.30-0.40    >0.40
Earthquake intensity          \VI    VI      VII        VII        VIII      VIII       >IX

Here is the reference for the 2001 map: People's Republic of China National Standard (PRCNS), 2001, Seismic ground motion parameter zonation map of China, GB 18306-2001, China Standard Press.

The 1956 map was the first Chinese national hazard map. I don't have the reference for this, but will track it down.

Thanks.

Zhenming

Thanks for these maps, Zhenming. As nearly as I can tell, the PDE epicenter of the 2009 M7.9 Wenchuan earthquake plots on the two maps at 0.10 g (PGA) and IX or larger. Do you know what intensity scale was used for the 1956 map?

Also, in case any of us would like to cite the maps, do you know the other elements of their formal citations (author, title, publisher, place of publication, scale of publication)? E.g., I'd like to add the citations to an ms. when it returns from journal review. The 2001 map is much more detailed than the 1999 GSHAP map.
