The geotechnical experts are now saying they think the event was essentially a beach "avalanche".
Water undermined
the beach zone, and
the beach and adjoining 100 metre area, effectively "slumped" into the sea, like an avalanche taking off downhill.
The entire area underneath the
camping area would probably be
well-saturated with water in the soil, so that would have a lubricating effect, making the soil move seawards more easily.
There is talk that the entire sand peninsula could disappear in time, due to similar events. But that time period could be up to a couple of hundred years, no-one really knows.
