Rockfalls from the 25th October 2018 M=6.8 Zakynthos earthquake<\/h4>\n

On 25th October the M=6.8 Zakynthos earthquake struck offshore the west coast of Greece<\/a>, at a depth of just 14 km.\u00a0 The USGS Shakemap data<\/a> is presented in the map below:-<\/p>\n

Fortunately, the location of the earthquake offshore limited the impacts, but there are reports of rockfalls on the rugged island of Zakynthos. To date only one image has emerged (as far as I can tell), showing a significant collapse on Myzithres Beach. Ermisnews has this before and after pair of images<\/a> of the event at Myzithres Beach:-<\/p>\n

Potentially the most significant rockfall occurred on the famous tourist site known as Shipwreck Beach.\u00a0 This area had been subjected to rockfalls prior to the earthquake<\/a>, but a significant failure appears to have occurred.\u00a0 Unfortunately no images are yet available.\u00a0 Imerazante has a good image of the collapse in September<\/a>, with appears to have occurred on face-parallel joints:-<\/p>\n

Meanwhile, Neakriti has some images after the September 2018 event<\/a>:-<\/p>\n

Meanwhile, there are also reports of rockfalls on inland slopes.\u00a0 Neakriti reports<\/a> that in Panagoula<\/span> on Zakynthos several houses have been evacuated due to the risk of rockfalls.\u00a0 The aftershock sequence appears to be quite active, so further rockfalls cannot be ruled out, and there will also be a substantial level of hazard in the next major rainfall event.\u00a0 Meanwhile there is also some evidence of liquefaction or foundation problems in the port at Zakynthos<\/a>, as would probably be expected in an event such as this.<\/p>\n","protected":false},"excerpt":{"rendered":"
