4.9 quake 13 Mar 12:42 am (GMT +10)
An earthquake of magnitude 4.9 occurred after midnight on Saturday 13 March 2021 at 12:42 am local time near Lae, Morobe Province, Papua New Guinea, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the United States Geological Survey which listed the quake at magnitude 5.1. A third agency, Indonesia's Meteorology, Climatology, and Geophysical Agency, reported the same quake at magnitude 5.3.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kainantu (pop. 8,500) located 115 km from the epicenter, Madang (pop. 27,400) 116 km away, and Lae (pop. 76,300) 118 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
