Land Subsidence
San Joaquin Valley
subsidence
Land subsidence is the downwarddisplacement of the land surfacerelative to certain reference surface,such as mean sea level (MSL) orreference ellipsoid.
It may occurs in active volcanic andtectonic areas, mining areas, oil andgas exploration areas, and largeurban areas.
Can be caused by natural and/orhuman activities.

Land Subsidence & Urban Development Increase in Populationand Built-up Areas
Urban development in Jakartais going-on rapidly
better infrastructure, high concentration and access to mass markets pool of skilled labour and entrepreneurs high access to the decision makers
Jakarta has been the most attractive area in Indonesiafor domestic and direct foreign investment because of[Firman and Dharmapatni, 1994] :
Hasanuddin Z. Abidin, 2009
The increase inpopulation and

New residential areas, industries,condominiums, malls, hotels, commercialsand office buildings have proliferated inJakarta in the last three decades.
In 2006, there are already 306 hotels, inwhich 135 are star (classified) hotels; and1955 large and medium manufacturingcompanies in Jakarta [BPS Jakarta, 2007].
