Peak ground shaking is classified at MMI V (Moderate) with a theoretical human perception radius of approximately ~37 km.
M4.8 Shaking Intensity & Scientific Telemetry near 31 km SE of Kainantu, Papua New Guinea
Ground shaking was recorded throughout 31 km SE of Kainantu, Papua New Guinea and neighboring regions in Papua New Guinea. The intermediate-depth focal depth of 124.1 km placed this event within the subducting slab interface, generating noticeable shaking in nearby population centers.
Tectonic Plate & Fault Line Setting: Papua New Guinea
Tectonic Setting: Australian, Pacific & Bismarck Microplates. Crustal stress accumulation along local fault lines in Papua New Guinea periodically triggers localized seismic shocks. Review community felt reports, localized epicenter coordinates (-6.5103°N, 146.0489°E), and historical seismic activity for this region.
Frequently Asked Questions About M4.8 Earthquake near 31 km SE of Kainantu, Papua New Guinea
Was there an earthquake just now near 31 km SE of Kainantu, Papua New Guinea?
Yes. An earthquake of magnitude M4.8 was recorded near 31 km SE of Kainantu, Papua New Guinea on Sun, 18 Oct 2026 00:28:29 GMT. Seismological telemetry registered a focal depth of 124.1 km.
Where was the epicenter of the M4.8 31 km SE of Kainantu, Papua New Guinea earthquake?
The epicenter was located at geographic coordinates latitude -6.5103°N, longitude 146.0489°E at a focal depth of 124.1 km beneath the Earth's crust.
Was the M4.8 earthquake near 31 km SE of Kainantu, Papua New Guinea dangerous?
Moderate seismic event capable of rattling fixtures, windows, and light objects. Widely felt in nearby communities.
How deep was this earthquake and why does focal depth matter?
This event occurred at a focal depth of 124.1 km (Intermediate Depth (35-150 km)). Shallow crustal earthquakes release concentrated seismic energy directly toward the surface, producing stronger ground acceleration than deeper mantle ruptures.
Should aftershocks be expected following this tremor?
Yes. Aftershocks are expected following seismic ruptures as tectonic stress redistributes along adjacent fault planes. Aftershock frequency generally decays over time according to Omori's Law.
What should I do during an earthquake?
DROP immediately onto your hands and knees, COVER your head and neck under a sturdy desk or table, and HOLD ON until ground shaking completely ceases.
