The Mantle Magnitude Mm and the Slowness Parameter : Five Years of Real-Time Use in the Context of Tsunami Warning

We study a database of more than 119,000 measurements of the mantle magnitude Mm introduced by Okal and Talandier (1989), obtained since 1999 as part of the operational procedures at the Pacific Tsunami Warning Center. The perfor- mance of this method is significantly affected by the seismic instrum... View More
