..., on the amplitude decrease, and the very rapid dispersion of the periods of one earthquake of intermediate focal depth. Data from three deepfocus earthquakes support this interpretation. Thus, the long-period precursors are not due to the same cause as short-period precursors and are not produced by discontinuities...

... to surface wave magnitude ( M S ) by log E R = 1.5 M S + 11.8. Earlier studies used this empirical relation to estimate energy (e.g., Wyss and Brune, 1971 ). Radiated energy has also been estimated from the average pulse widths of P -wave arrivals for deepfocus earthquakes ( Vassiliou and Kanamori...

... behavior. Most deep earthquakes (depth > 70 km) in the mantle occur in subducting slabs. They are further categorized as intermediate-depth earthquakes (70-350 km depth) and deepfocus earthquakes (350-700 km depth). The cause of deep earthquakes is still a major scientific puzzle. In this session, we...
