Aftershock of Nevada Earthquake Felt in California

Click For Summary
SUMMARY

The forum discussion centers on the aftershocks of a 6.5 magnitude earthquake in Tonopah, Nevada, which was felt as far as 150 miles away in California. Participants noted the occurrence of a second earthquake, a 5.8 magnitude event from the Tonga region, recorded shortly after the Nevada quake. The conversation highlights the potential for misinformation among non-scientists regarding the connection between these two seismic events, emphasizing the need for informed commentary from experts to prevent misunderstandings.

PREREQUISITES
  • Understanding of seismic event magnitudes (Mw)
  • Familiarity with earthquake recording methods and mediums
  • Knowledge of the US Geological Survey (USGS) earthquake reporting
  • Awareness of common misconceptions in seismic activity discussions
NEXT STEPS
  • Research the USGS earthquake event pages for detailed seismic data
  • Study the principles of earthquake magnitude measurement and reporting
  • Explore the impact of social media on public perception of scientific events
  • Learn about the geological differences between tectonic plates in Nevada and Tonga
USEFUL FOR

Seismologists, geologists, science communicators, and anyone interested in understanding earthquake phenomena and public misconceptions surrounding seismic events.

Yes, I recorded this one, not a spectacular amplitude because of the distance

https://earthquake.usgs.gov/earthquakes/eventpage/nn00725272/executive <--- the 6.5

https://earthquake.usgs.gov/earthquakes/eventpage/us70009gsj/executive <--- The 5.8

there's 2 events a few hours apart on the trace
Firstly, the Mw 6.5, Nevada, then a Mw 5.8 from the Tonga region ( South Pacific)

Obvious question - the Tonga event is there because it is on/in the same recording medium close to the same time. No connection.

Do you think non-scientists are going to "derive" some baloney connection without an informed comment
on the expert's part? Or I have just seen too many weirdo comments?

Yes, Correct :smile:

It happens all the time.
Social media and other Q&A forums, eg Quora, are full of dopey questions and comments along those lines :rolleyes:
