Last year I went to Trieste, Italy where I found same situation along the coast line of Adriatic sea. The area is mainly composed of carbonates and these are carved by the river which is flowing on the Northeastern side of the area. A fault is also running through the area which has multiple scarps showing many events in the past. Many geologists marked it as a plate boundary. Anyway the whole city is built on the caves and somewhere hollow subsurface. The perfect example is the presence of old caves and underground water channels in the area.Here is a link about a cave there http://en.wikipedia.org/wiki/Grotta_Gigante.
As you said many reasons for these sinkholes e.g before volcanic eruption, due to fault movement, Liquefaction, continuous recharge, Presence of Aquifers, Salt and many more.
Cheers- Aamir
