Table 5. Risk score.

Data	Weight	Contents
gyro_magnitude	0.4	Indicates the vibration state of the building and is weighted highly because the greater the vibration, the higher the risk.
tilt_angle	0.4	Tilt changes are highly weighted as they are associated with building imbalances, swaying, etc.
Altitude_change	0.2	Elevation changes are given less weight than relative vibration and tilt changes because this is considered more indirect.
