Nice article. 20,000 years ago at the peak of the last ice age, sea levels were 120 meters lower than today.
"Sea level was 400 feet lower then because huge ice caps two miles deep covered most of Europe and North America. But as the ice caps began to melt all the water stored in them returned to the oceans and sea-level rose, submerging many parts of the world where humans had previously lived. Thus Britain was joined to Europe during the Ice Age (there was no English Channel or North Sea). Likewise there was no Red Sea, no Persian Gulf, Sri Lanka was joined to southern India, Siberia was joined to Alaska, Australia was joined to New Guinea - and so on and so forth. It was during this epoch of sea-level rise, sometimes slow and continuous, sometimes rapid and cataclysmic, that the Ice Age continent of Sundaland was submerged with only the Malaysian Peninsula and the Indonesian islands as we know them today high enough to remain above water." The following map of 20,000 years ago shows Indonesia as part of the Asian mainland and almost Asia -- as well as significant continental land connections. And this provides insight as to why virtually all cultures have a Great Flood mythology / traditions. Coasts and rivers are often the hubs of civilizations and progress. How many civilizations and cultures for which we have no clue may have perished without a sign during the numerous dramatic rises and falls of oceans in the past 100,000-200,000 years since homo sapiens emerged?

It is covered with massive rectangular stones of volcanic origin. The Sundanese people http://en.wikipedia.org/wiki/Sundanese_people consider the site sacred and believe it was the result of King Siliwangi http://en.wikipedia.org/wiki/King_Siliwangi's attempt to build a palace in one night.

Should this occur, coastal cities, ports, and wetlands would be threatened with more frequent flooding, increased beach erosion, and saltwater encroachment into coastal streams and aquifers. Global sea level has fluctuated widely in the recent geologic past. It stood 4-6 meters above the present during the last interglacial period, 125,000 years ago, but was 120 m lower at the peak of the last ice age, around 20,000 years ago. A study of past sea level fluctuations provides a longer-term geologic context, which can help us better anticipate future trends."
