The web page is showing the locations of the seismograms and whether they are transmitting CURRENT data. Not that any significant seismic event has
happenned, just that they are working. If you actually click on one of the triangles it then gives you specific information regarding the
instrumentation used, ie: coordinates, status, etc. Nothing to be alarmed about.
