SUMMARY

Two significant seismic events measuring M 7.6 occurred in central Peru, with depths of 600 km and 606 km, as reported by the USGS. The events were recorded on seismographs, with distinct P wave arrival spikes noted by observers. The depth of these earthquakes is expected to mitigate their impact, allowing for widespread sensation without severe localized damage. No reports of injuries have been confirmed as of the latest updates.

PREREQUISITES
  • Understanding of seismic wave types, particularly P waves.
  • Familiarity with seismograph operation and data interpretation.
  • Knowledge of earthquake magnitude scales, specifically the Richter scale.
  • Awareness of geological features, such as the Andes mountains and their impact on seismic activity.
NEXT STEPS
  • Research the USGS earthquake reporting system and data updates.
  • Study the effects of deep earthquakes on surface impact and damage.
  • Explore seismic data analysis techniques using seismographs.
  • Investigate historical seismic events in the Andes region for comparative analysis.
USEFUL FOR

Seismologists, geologists, emergency response teams, and anyone interested in understanding earthquake dynamics and their implications on populated areas.

still coming in on my seismo gear

151124 2245 and 2250UT M 7.6 and 7.6 double event Peru zhi.gif


USGS info...
2245UT M 7.6 600km deep
2250UT M 7.6 606km deep

Note magnitudes may change a little after more station data is reviewed by the USGS

on my mate's short period seismo sensor, the 2 separate large P arrival spikes are clearly visible
( he is around 250km NNW of my location)
his recording shows that the P wave od the second event didn't hit the same amplitude as the first one

Earth sciences news on Phys.org
Ouch! Two big ones in a row. Any reports of injuries yet?
 
not that I have heard

was just googling news in them ... gosh there is masses of garbage posts ... really shocking

this pair of events are well on the east side of the Andes mountains, on the border with Brazil)
fortunately their great depth 600km is going lessen the impact greatly... well felt over a wide area
rather than very intense in a close in area if they were shallowDave
