<br><font size=2 face="sans-serif">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?</font>
<br>
<br><font size=2 face="sans-serif">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.</font>

Here are the Chinese 1956 intensity (the largest historical intensity)
and 2001 PGA (10 % PE in 50 years PSHA) hazard maps. <br>
<br>
Relationship between the intensity and peak ground acceleration (PRCNS,
2001)<br>
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<br>
