But Manila trench located in southern Taiwan on the east boundary of the South China Sea and west of Philippine,not only has the background of seismic tsunami,but also is a subduction zone from South China Sea to Phili.

According to the activity of earthquakes and volcanoes along the Manila trench and its adjacent region, combined with analysis of focal mechanism solutions and geophysics data, the Manila trench is still being downward subduction in the depth of 200 km.

Two subduction zones, the Ryukyu trench and Manila trench, exist in the East Asia continental margin.

THE ECOLOGICAL OBSERVATION OF Barnea manilensis;

Effects of different trampling intensities on the bermudagrass and manilagrass;

Effects of Different Turf-beds and Trampling Intensities on the Bermudagrass and Manilagrass;

Manilagrass was trampled by 4 trampling intensities in 3 courses.

This research also discussed feasibility of the applied SMS as the substitute component in the culture of Coprinus comatus, as the organic fertilizer for planting navel orange, and as soilless culture for planting manila grass so as to utilize the resource of SMS and provide scientific basis for extending the recycle chain of biological resources.
