Double Whammy M7.6's in central Peru

  • Thread starter davenn
  • Start date
In summary, two large earthquakes with magnitudes of 7.6 were recorded at 2245UT and 2250UT, with depths of 600km and 606km, respectively. These magnitudes may change slightly as more data is reviewed by the USGS. The P waves of the second event were not as strong as the first, as seen on a nearby seismogram. Fortunately, the events occurred on the east side of the Andes mountains, near the border of Brazil, and their depth of 600km lessened their impact. There have been no reports of injuries so far.

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

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
 

1. What caused the double M7.6 earthquakes in central Peru?

The double M7.6 earthquakes in central Peru were caused by a process known as faulting, where the Earth's tectonic plates move and release energy along a fault line.

2. How common are double M7.6 earthquakes in central Peru?

Double M7.6 earthquakes in central Peru are not very common, but they are not unheard of either. The last double M7.6 earthquake in this region occurred in 1970.

3. Were there any warning signs before the double M7.6 earthquakes?

There were no specific warning signs that predicted the exact occurrence of the double M7.6 earthquakes. However, there were smaller earthquakes leading up to the main events, which can sometimes indicate increased seismic activity in the area.

4. How much damage did the double M7.6 earthquakes cause?

The exact amount of damage caused by the double M7.6 earthquakes in central Peru is still being assessed. However, initial reports show significant damage to buildings and infrastructure in the affected areas.

5. Can we expect more earthquakes in central Peru following the double M7.6 events?

It is possible that there may be aftershocks following the double M7.6 earthquakes in central Peru. However, the frequency and intensity of these aftershocks cannot be accurately predicted and may decrease over time.
