The co-seismic slip distribution of the 2011 Tohoku megathrust earthquake is constrained from GeoForschungsZentrum (GFZ) Gravity Recovery and Climate Experiment (GRACE) Level 2 data time series and our self-gravitating, compressible 1-D Earth model. After spatial localization of space gravity data in the surrounding of the U.S. Geological Survey (USGS) epicenter by means of orthogonal Slepian functions, we estimate the long-wavelength co-seismic gravity signature.

The earthquake didn't do the damage, the tsunami did. Or was the tsunami fake to?

A moment to remember.
On March 11th, 2011, the day had started like any other, and we were talking about a 7+ earthquake that had happened in Japan. I had GEE up at the time, and had stepped away from the computer to cook dinner. In between duties, I was occasionally coming back in to have a glance at GEE.
Well you can imagine my surprise to see this:
The waveform was clipped, meaning the stations ERM and MAJO had saturated out. And showing 8+ mm/sec already! I knew that was BAD, BAD news immediately. Someone posted the initial thread literally a minute before I could. I don't know if I ever told you guys this, but I went on GEE later and found the closest non-clipped waveform I could find, and it was at station YSS. It was well over 9 mm/s, and a beast of beasts. The rest is history.
I am of the opinion that I will never see another quake that big or bigger in my lifetime. And if I do, then something is wrong, and out of the statistical norm.
Happy Holidays to all!
The magnitude equivalent would have been an 8.246 against the next lowest in 2008 of Mag 8.281
Magnitude equivalent is the Magnitude value if all the energy released in the year had been released as a single earthquake. For the analysis of which areas saw a big decrease I am afraid you will have to wait for the full report.
