The 3rd of 6 photos (see below) of the subsidence hole that appeared on Dover's seafront promenade on Friday, July 11th, 2008.

An interior view taken from just in front of the designated cycle path.

There are 6 photos altogether (though I may add more later), taken over a period of 5 days:

1 The hole as first seen on Friday, July 11th

2 The expanded hole and partial shoring on Monday, July 14th

3 Interior of the hole on Tuesday, July 15th

4 The hole looking West on Tuesday, July 15th

5 The hole looking East on Tuesday, July 15th

6 Wide-angle view of the hole on Tuesday, July 15th

These photos are also indexed under the "Holes" tag.

Photos 1 and 2 were taken using my Samsung G800 5 Mpx camera phone, the others with a Pentax K100D DSLR.

Its a sinkhole, if caused by drainage, or a washout, if caused by water from the sea (however propelled )

A washout can be caused by a ship or tugboat tied up or just working nearby, and with these modern thrusters there's a strong jet which can liquify the mud that was covered over to the make the wharf... They'll probably inspect all along and have to seal off loose soils.

Thank you for your message, Isilder!

The hole appeared towards the middle of the 1500 yard long seafront promenade, about 6 or 7 yards behind the seawall proper.

An underground river (Eastbrook) heads towards the sea in this direction and there are a number of very small freshwater springs on the pebble beach below the seawall at low tide. No shipping passes anywhere near this location.
