date, time, region, depth latitude, longitude, moment (in N m), m_xx, m_yy, m_xy -- Harvard CMT data between 1 Jan 1976 - 31 Dec 2003 and All events are less than 40 km deep. In the actual model only the events are used that are within the defined plate boundaries of the model; i.e., no intraplate events are used. -- coordinate system is x - east, y - north, z- up. Note that this is different from Aki and Richards, which is x - north, y - east, z - down. If you need to convert from Aki and Richards; m_xx = m_yy, m_yy = m_xx, m_xy = m_xy
