Discussion Overview
The discussion centers around the seismic events occurring near New Caledonia, specifically a Mw 7.5 earthquake and its associated foreshock and aftershocks. Participants share observations from seismograms and updates on the magnitude of the aftershocks.
Discussion Character
- Exploratory, Technical explanation, Experimental/applied
Main Points Raised
- One participant reports a Mw 7.5 earthquake located 168 km ESE of Tadine, New Caledonia, noting it was preceded by a Mw 6.0 foreshock just 4 minutes earlier.
- Another participant updates the thread with information about a Mw 7.0 aftershock, which was later downgraded to a M 6.6.
- Additional posts include a map of earlier aftershocks, with labels provided by a participant.
- A raw seismogram of the Mw 7.5 earthquake is shared, highlighting the P and S wave arrivals.
Areas of Agreement / Disagreement
Participants generally agree on the occurrence of the Mw 7.5 earthquake and its foreshock and aftershocks, but there are updates regarding the magnitude of the aftershocks that indicate some uncertainty.
Contextual Notes
Details about the specific characteristics of the seismic events, such as the timing and location of the foreshock and aftershocks, are provided, but there may be limitations in the data shared, such as the accuracy of the aftershock magnitude updates.
