Phalasarna was a Hellinistic port that was massively uplifted (~8 m) during the well-known 365 AD M>8 Crete #earthquake.
Perched notches are also visible in the area.

This matches very well with traces of the surface rupture visible a few km to the north on the high resolution Planet SkySat images (thank you Planet!). The offset road is the northernmost point on the overview, and I measured about 4.5 m of offset there.

Quick recap from todays recon of yesterdays M5.8 earthquake. Bottom line: no surface rupture observed after several transects across aftershock pattern. Lack of any surface cracking in epicentral area. Minor bank failures, lateral spread, and liquefaction features along Walker river.
