SUMMARY

A preliminary magnitude Mw 7.9 earthquake occurred offshore of Southeast New Ireland, Papua New Guinea. The quake's depth was recorded at 103.2 km, indicating a low likelihood of generating a tsunami. This event follows a previous Mw 7.8 earthquake in the Solomon Islands, approximately 1200 km away. Local news reported a tsunami alert, but no cancellation notice was issued when the tsunami did not materialize.

PREREQUISITES
  • Understanding of seismic magnitude scales, specifically Mw (Moment Magnitude).
  • Familiarity with earthquake depth implications on tsunami generation.
  • Knowledge of earthquake monitoring tools like USGS event pages.
  • Awareness of regional seismic activity patterns, particularly in the Pacific Ring of Fire.
NEXT STEPS
  • Research the implications of earthquake depth on tsunami risks.
  • Explore the USGS earthquake event reporting system for real-time updates.
  • Investigate historical seismic events in the Solomon Islands and Papua New Guinea.
  • Learn about earthquake preparedness and response strategies in coastal regions.
USEFUL FOR

This discussion is beneficial for seismologists, disaster response planners, and individuals interested in understanding seismic events and their implications on local communities.

The cluster of yellow dots in the lower right is of the M 7.8 a week ago in the Solomons region
there's around 1200km between these 2 major eventsDave

Well ... it generated a tsunami alert in the local news, but no cancellation notice for same when it/the tsunami failed to materialize ... winter storm "Decima" seems to be hogging the headlines far as natural disasters go. That's another "news" item for investigation ... failure to "multi-task" far as attention spans go ... there really is a "single focus" that is "hard-wired" into our attention mechanisms.
