It caused severe damage in Ierissos, Greece and the surrounding part of the Chalkidiki peninsula, with 161–491 casualties reported. Tectonic setting The Aegean Sea is an area of mainly extensional tectonics caused by the subduction of the African plate beneath Aegean Sea plate. In the northwest Aegean, extension on approximately W-E trending extensional faults is accompanied by dextral (right lateral) strike-slip on SW-NE trending faults, and minor sinistral (left lateral) movement on NW-SE trending faults, accommodating the diffuse plate boundary zone between the Eurasian plate and the Aegean Sea plate.https://earthquake.usgs.gov/earthquakes/world/greece/tectonic_summary.php Tectonic Summary of Greece United States Geological Survey 29 March 2010 26 July 2010 https://web.archive.org/web/20100729002223/http://earthquake.usgs.gov/earthquakes/world/greece/tectonic_summary.php 29 July 2010 dead The earthquake has been attributed to movement on the Stratoni fault, one of the W-E trending faults that shows predominantly dip-slip extension.Pavlides S.B.

The cost of the damage was estimated as 5 million drachmas.http://www.ngdc.noaa.gov/nndc/struts/results?eq_0=3502&t=101650&s=13&d=22,26,13,12&nd=display https://web.archive.org/web/20210731120231/https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=3502&t=101650&s=13&d=22,26,13,12&nd=display dead July 31, 2021 Comments for the Significant Earthquake NGDC 1 August 2010 The minor tsunami caused no damage.http://www.ngdc.noaa.gov/nndc/struts/results?eq_0=3502&t=101650&s=18&d=99,91,95,93&nd=display https://web.archive.org/web/20191231000109/https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=3502&t=101650&s=18&d=99,91,95,93&nd=display dead December 31, 2019 Comments for the Tsunami Event NGDC 1 August 2010 Characteristics The Stratoni fault was identified as the fault responsible for the 1932 event because of evidence of surface ruptures recorded soon after the earthquake and from the pattern of isoseismals, which were elongated in a W-E to NW-SE orientation and similarly orientated volume of recently observed seismicity. From the observation of slickensides along exposed fault planes, the movement along the fault is dip-slip extensional with local areas of oblique slip with a component of sinistral (left-lateral) strike-slip. The extension direction is currently oriented north–south but, when the fault was formed, was oriented NNE-SSW, perpendicular to the fault trace, possibly due to subsequent clockwise rotation of the area. The earthquake was followed by three strong aftershocks (M=6.0, 5.7 & 6.2) in the period 26–29 September, and the largest (M6.3) on 11 May of the following year. A minor tsunami was reported, which was recorded by a temporary tide gauge, giving a maximum height of 1 m. The movement awoke the operator of a dredger, who saw a current spreading up the Strimonas River about an hour after the earthquake.
