Abstract
A new method is presented for the determination of higher mode dispersion over small distances, using two stations.
From an intermediate focus earthquake it has been possible to measure the dispersion of the first and second Rayleigh modes in the period range 25–35 sec and 25–70 sec respectively.
Using the almost linear array of Italian long-period stations TRI, BLZ, OLB an estimate of the average errors is also made.
