EMSC has revised the magnitude up to 7.9 and the latest PTWC message had 8.1, and considering the "A Team" at USGS isn't there on weekends, I suspect the magnitude was higher than 7.6.
It always seems like the initial magnitude reports for large earthquakes are low.
The Boxing Day Earthquake was initially reported as a 7.6 on the Richter Scale. They just kept moving the magnitude, along with the death toll, higher. Ended up as a 9.1. Hopefully, this won't be the case this time. And anyone know the difference between Moment and Richter magnitudes? Richter was 7.6 for this, but Moment was 8.1.
