Abstract
This chapter presents the main features hitherto imaged and detected by seismology. Seismological imaging has revealed the most important part of the subsurface structure of the Himalayan orogen, and also enabled other geophysical methods to interpret their datasets in terms of deep structure. Seismometers operate continuously, and it is usually computers that detect the arrival of elastic waves. Instrumental seismicity is detected by stations around the globe for large magnitude events, and locally deployed seismometer networks allowed to delineate features that cause moderate and very small earthquakes. Global networks detect all moderate and large events, and further temporary networks zoom into the key parts of the orogen. Such glimpses into seismic activity are extremely useful, even though they are not representative of the seismic cycle. The current pattern reflects well the main structural features of the orogen, namely, underthrusting, lateral variations and even some key across-strike features such as the localized Dhubri-Chungthang Fault zone.
