Fig. 4

Sensitivity testing of nowcast scores for different cities in Sulawesi region. The first subplot demonstrates the circular city region for the Palu city corresponding to a radius of 250 km, 300 km, and 350 km. Current number of small event counts since the last major earthquake in each circular city region are shown in the lowermost panel. These EPS values, however, bear no information of the current level of earthquake hazards due to the stationary Poissonian nature of the underlying natural-time statistics
