The 1992 Nicaragua earthquake: a slow tsunami earthquake associated with subducted sediments
Article Abstract:
The 1992 Nicaragua earthquake caused a large tsunami and exhibited seismic features characteristic of 'tsunami earthquakes.' The difference between the moment magnitude, which is calculated from long-period surface waves, and the surface-wave magnitude, which is calculated from short-period surface waves was great, a feature of tsunami earthquakes. Slow motion of the subduction interface between the North American and Cocos plates in the absence of ocean floor sediments off the Nicaraguan coast caused a slow thrust earthquake that propagated the ensuing large tsunamis.

Energy radiation from the Sumatra earthquake
Article Abstract:
The duration of high-frequency energy radiation from Indonesia's great Sumatra-Andaman earthquake was about 500 seconds. This duration can be translated into a rupture length of about 1,200 km, which is more than twice as long as that inferred from body-wave analyses performed soon after the event.

Earthquake physics and real-time seismology
Article Abstract:
Several real-time seismology studies are conducted to explain the physics and complexity of the earthquakes. The findings show that the new technologies should be adequately used to obtain the early-warning information for the same.
