According to the 2008b Update of the M8-MSc predictions dated Thursday, January 10, 2008 —
The first event falls within the limits of M8 TIPs for M7.5+ in CI# 31-33 (NORTHERN SUMATERA, INDONESIA) scoring a success to overall statistics of the first approximation and, in the absence of reduced area of alert, a failure-to-predict to that of the second one.
The second event, the disastrous Wencheng (Sichuan, China) earthquake, was not predicted in our Test: its epicenter hits CIs ## 250 (SICHUAN, CHINA) and 253 (YUNNAN, CHINA) in testing aimed at M8.0+ and is too far from CIs in testing aimed at M7.5+.
