Sidao Ni is a seismologist at the Institute of Geodesy and Geophysics, Chinese Academy of Sciences. He is interested in identifying and understanding triplicated, multi-pathed or converted seismic phases on seismograms, which are then used to study seismic sources or internal interfaces of the Earth. He found sharp lateral boundaries inside the deep mantle, and demonstrated that the 2004 great Sumatra earthquake featured the longest rupture size and source duration among all instrumentally recorded seismic events. He and colleagues also discovered new persistent localized microseismic sources in the Gulf of Guinea and near the Vanuatu Islands.
