6.6-Magnitude Earthquake Strikes Papua New Guinea: Impact & Shake Map Analysis (2025)

A powerful earthquake, registering a significant **6.6 on the magnitude scale, has jolted Papua New Guinea, sending ripples of concern across the region.** This seismic event, as reported by the United States Geological Survey (U.S.G.S.), occurred on Tuesday. Let's dive into the details.

The epicenter of the temblor was located approximately 16 miles southwest of Lae, Papua New Guinea, according to the U.S.G.S. data. The earthquake struck at 9:05 p.m. Papua New Guinea time.

But here's where it gets interesting: The U.S.G.S. is constantly refining its data. As seismologists analyze more information, the initial magnitude of 6.6 could be adjusted. They may also update the shake-severity map based on the additional data collected. This means the initial assessment is just the first look; the full picture often emerges as more information becomes available.

The map accompanying the report shows the areas where the shaking intensity was 4 or greater. The U.S.G.S. classifies this as 'light,' but remember, the effects of the earthquake might be felt beyond those highlighted areas. All times mentioned are in Papua New Guinea time, so keep that in mind when considering the timeline of events.

It's important to note: The shaking categories are based on the Modified Mercalli Intensity scale. When aftershock data becomes available, the maps and charts will include any subsequent earthquakes within 100 miles and seven days of the initial quake. The shake data was current as of Tuesday, October 7th, at 7:24 a.m. Eastern Time, and the aftershock data was current as of Wednesday, October 8th, at 7:36 a.m. Eastern Time.
