Multiple Strong Global Earthquakes within the Past 72 hours

Hello all,
There have been at least three or four strong magnitude global earthquakes (Aleutian Islands, Iran, China) occurring during the past 72 hours…

Editor's Notebook: The deadliest earthquake was located in Northwest Iran
where at least 150 casualties were reported by the news media. Coincidentally there was an M1.0 Class X-ray Solar Flare which erupted from NOAA Active Region 1540 with a Peak flux measurement approximately three minutes earlier than a Magnitude 6.4 seismic event's origin time, which was at 12:23 UT on August 11, 2012.

PRESTO FROM SIDC – RWC BELGIUM Sun Aug 12 2012, 1237 UT

Due to decreased X-ray background flux and decay of the NOAA AR 1540 (that produced an M1.0 flare yesterday), we expect flaring activity only at the C-class level, most probably from NOAA ARs 1542 and 1544.
The Earth is currently inside a slow (around 350 km/s) solar wind flow with average (5-6 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions.
