WebThe seismic moment, M0, is 2.2×1026 dyne-cm. From spectral analysis of teleseismic velocity, the radiated energy, Es, is estimated to be 1.1×1022 dyne-cm, implying an apparent stress of 15 bars. From the high-frequency level of the teleseismic acceleration spectrum and a rupture area of 440 km2, we derive a dynamic stress drop of 51 bars. WebThe main characteristics of OLAP are as follows: Multidimensional conceptual view: OLAP systems let business users have a dimensional and logical view of the data in the data warehouse.
