Abstract
Additional evidence for this conclusion comes from my study of eleven intracontinental earthquakes, with magnitudes ranging from 4.9 to 6, which occurred in the mantle beneath the western Himalayan syntaxis, the western Kunlun Mountains, and southern Tibet (near Xigaze). High-resolution seismic waveforms show that some focal depths exceeded 100 km, indicating that these earthquakes also occurred in the mantle lithosphere, even though the crust has been greatly thickened.
