During seawall reconstructions between 25th of September 2012 and 31 December 2013 the profile of the seawall was slightly deformed. The animation below shows where in the profile of the seawall is under influence of compressive strain and tensile load.
Remarkably, the profile at kilometer 86.2 shows the classic behavior of undermining the seawall at the sea-side, while at kilometer 86.1 there is actual light superficial shear.
At the crown of the seawall It is very clear too see a definite "break point" and that, as expected, the seawall at sea-side (right) moves a lot more than the land side.
The animation shows the actual behavior as measured by the sensors between 25-09-2012 and 31-12-2012 10:25 and is amplified by 300x.
