a Source amplitude versus moment magnitude for manual CMT solutions (black circles) of earthquake events in the Philippines and Indonesia and for automatic CMT solutions (red circles) of events in the Philippines. b Source amplitude ratios calculated from source amplitudes shown in (a) versus moment magnitude. Bold red circles are source amplitudes and source amplitude ratios of non-seismic pulses
