The event was filed by Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the first seismological agency to report it.
Our monitoring service identified a second report from the German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 4.9. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.6.
