Magnitude 8.8 OFFSHORE MAULE, CHILE  Saturday, February 27, 2010 at 06:34:14 UTC

---------------------
I have some basic questions of USGS. Why is the duration of the earthquake not listed? Why is the duration to different magnitudes not listed? Why is the wavelength and frequency not listed. Why are the raw seismographic waveforms not shown? It is frustrating to not have this data. 
------
Magnetosphere
I will try and find data on this prediction and the coronal mass ejection associated.
I have not found data on the magnetosphere yet. I need to go for now. I will place the data here.

There is an asymptote on Feb 24 2010.
