| Abstract | ||
| One type of magnitude formula are preliminarily developed from Kuwait National Seismic Network (KNSN) data which is proposed and intended for application by the network in its seismic monitoring activities. This is the duration magnitude scale of measurement which are empirically determined and expressed as: MD = 2.66 log(τ) + 0.036Δ - 1.97 + Ci. The magnitude formula is the result from applying multiple regression techniques to the data which have the seismic signal duration, τ, that are availed from 6 stations of the network. To ensure applicability of the magnitude equation for the network, stations corrections were determined which are indicated by the Ci for the ith station. The station corrections are evaluated from the average of the difference values between the proposed magnitude formulas to respective magnitude equations obtained from each seismic station. | ||
