A drawback will occur as the shoreline recedes dramatically, exposing normally submerged areas. Drawback can exceed hundreds of metres, and people unaware of the danger sometimes remain near the shore to satisfy their curiosity or to collect fish from the exposed seabed.
What would cause land in a sinking region to rise such that the sea recedes from the shore? Such an exposed sea shore, with fish suddenly out of the water and boats stranded, is famously known as a warning sign for a pending tsunami. The water recedes and then comes back with a vengeance. The Indonesian island of Java is sinking, as part of the 7 of 10 plate movements, and this has been going on for three years. Jakarta holds the sea at bay with sea walls but is below sea level to the extent we predicted in 2010.
Why would a region near Jakarta find itself rising from the sea, then, as occurred in Banten recently? A land mass that is being pushed under another, as is happening along the Sunda Plate border wrapping to the south of Java, does not always slide smoothly. There are catch points where the slide resists, and the land being pushed under will heave, rise, during this time. This does not mean that the normal configuration will not return, after the slide is forced. And when the normal configuration returns the land will be LOWER than before. Banten should thus be wary.
