LDEO Seismology Research: Surface Wave Event Locations


Surface-wave event locations derived from Near Real Time Data

The map below show the locations of surface-wave sources identified by a systematic analysis of seismograms from the Global Seismographic Network and from other seismographic networks and stations. The figure shows the detections for the last week and is updated a few times daily.
