Statistics and Analysis of the Relations between Rainstorm Floods and Earthquakes

Table 5

Classification and weights of the influential factors for the relations between an earthquake and a rainstorm flood event.

Magnitude		⁢Time interval (months)		⁢Distance (km)		⁢Orientation
Scale	Weight	Scale	Weight	Scale	Weight	Orientation difference	Weight
6.0~6.9	0.1	0	1.0	0~499	1.0	The same orientation	1.0
