Expect some major damage.
Likely from the CME Impact
According to the information provided by the Athens observatory, the epicenter of the tremor was located “in the sea, 405 km southeast of Athens, at 09H24 GMT.” It is worth remembering that 15 days ago, another earthquake in Crete left one dead and a dozen injured.

Incoming CME Detected / Storm in Progress
October 12, 2021 @ 02:05 UTC
The CME from the M1.6 solar flare on October 9th has finally reached the DSCOVR spacecraft and should sweep past Earth within the hour. The solar wind speed looks to be near 500 km/s and the Bz component of the interplanetary magnetic field is currently in a south pointing orientation which is good news for the prospects of a geomagnetic storm. More to follow.
UPDATE @ 02:30 UTC: The magnetometer located in Boulder, Colorado just detected a sudden deviation in Earths geomagnetic field, marking the exact moment the CME swept past our planet. Geomagnetic storm conditions will be likely in the hours ahead. Aurora sky watchers should be alert.
UPDATE #2 @ 03:00 UTC: A geomagnetic storm is now in progress. The minor (G1) storm threshold was reached at 02:57 UTC. Moderate (G2) storming will also be possible. Visible aurora likely at middle to high latitudes tonight.
ALERT: Geomagnetic K-index of 6
Threshold Reached: 2021 Oct 12 0447 UTC
Synoptic Period: 0300-0600 UTC
Active Warning: Yes
NOAA Scale: G2 – Moderate
SUMMARY: Geomagnetic Sudden Impulse
Observed: 2021 Oct 12 0230 UTC
Deviation: 33 nT
