A magnitude 4.9 earthquake occurred on the morning of Monday, August 1, 2022 at 8:27 a.m. local time near Aitape, Sandaun, Papua New Guinea, as reported by the German Center for Geoscience Research (GFZ).
According to preliminary data, the earthquake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones because they are closer to the surface. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes as seismologists review the data and refine their calculations, or as other agencies release their report.
A second report was later released by the RaspberryShake Citizen Seismograph Network, which also listed it as a magnitude 4.9 earthquake. A third agency, the Euro-Mediterranean Seismological Center (EMSC), reported the same magnitude 5.1 quake.
Based on preliminary seismic data, the quake was likely felt by many people in the epicenter area. It must not have caused significant damage, other than objects falling off shelves, glass breaking, etc.
At Aitape (pop. 5,500) located 21 km from the epicenter, the earthquake should have been felt as light tremors.
Other towns near the epicenter where the quake could have been felt as a very weak tremor include Vanimo (pop. 11,200) located 122 km from the epicenter and Vanimo (pop. 11,200) 122 km away.

Seismic data

If you felt this earthquake (or if you were near the epicenter), please share your experience and submit a short “I felt it” report! Other users would love to hear about it!
If you did NOT feel the tremor although you’re around, thank you for reporting it! Your input is valuable to earthquake science, earthquake hazard analysis, and mitigation efforts. You can use your device location or the map to show where you were during the earthquake. Thanks!

Data for the same earthquake reported by different agencies

Info: The more agencies report the same earthquake and publish similar data, the more confidence you can have in the data. It normally takes up to a few hours for the seismic parameters to be calculated with near optimum accuracy.
