The generalized fractal dimensions are measured for M ≥ 3 shallow earthquakes with focal depths of ≤ 40 km in the Taipei Metropolitan Area (from 121.3 to 121.9°E and 24.8 to 25.3°N) over the 1973 - 2010 period based on spatial distribution (using epicentral and hypocentral distances between two events, r) and time sequence (using the inter-event time between two events, t). The multifractal measures are estimated from log-log plots of C_q(r) versus r and C_q(t) versus t, where C_q(r) and C_q(t) are the generalized correlation integral, respectively, of r and t at positive q. For the spatial distribution, C_q(r) is calculated based on the epicentral distance (i.e., the 2D measure) and hypocentral distance (i.e., the 3D measure). Under both 2D and 3D measures, the log-log plot of C_q(r) versus r shows a linear distribution when log(r_o) ≤ log(r) ≤ log(r_ub) and roll-over when r > r_ub. For all cases log(r_o) is 0.3, and log(r_ub) are 1.7 and 1.4 for the 2D and 3D measures, respectively. D_q, which is the slope of the linear portion, monotonically decreases with increasing q, thus indicating that the epicentral and hypocentral distributions of earthquakes are multifractal. The values of D_q are lower than 2 and 3, respectively, for the 2D and 3D measures. For the time sequence of the events in study, C_q(t) is calculated based on the inter-event time between two events. The log-log plot of C_q(t) versus t does not seem able to show a linear relationship in a large range of log(r) or r and the value of D_q cannot be evaluated, thus suggesting that the time sequence of M ≥ 3 shallow earthquakes in the Taipei Metropolitan Area (TMA) is not multifractal.
