The Record-breaking Nepali Mountaineer Cleaning Up The Himalaya
Intensive investigation on earthquake-waves and gravity observations of the final 35 years in distinctive parts of the earth have built up this notion of the structure of the earth. In the ‘continental layers’ the velocity of propagation of seismic waves-the longitudinal or compressional waves—is 5-five km./sec. Below the Mohorovicic Discontinuity, the velocity increases to about 8 km. The speed of the transverse or distortional waves of earthquake motion is a…Read More
