- The epicenter of the 03 January 2009 Mw7.6 event NEAR N COAST OF PAPUA, INDONESIA falls in a single circle of investigation (CI # 11) at 388 km from its center where no time of increased probability was diagnosed; the 19 March 2009 event in Tonga region also falls off the M7.5+ prediction (CI # 2) by less than 200 km, although hitting the area of alert for a larger magnitude event from M8.0+ range (M8.0+: CIs ## 2 and 3). Therefore, both earthquakes are counted as failures-to-predict in the overall statistics of the Global Test of M8-MSc predictions.
