Experts: Jakarta to sink by 2025

Monday, August 16, 2010


High tide floods 2007: “Signs of a sinking Jakarta”




Source: Presentation by Hongjoo Hahm and Janjaap Brinkmann (World Bank)


Brinkman’s statement that Jakarta might sink by 2025 was widely quoted by the media:

'The major reason for this is not climate change or whatever, but just the sinking of Jakarta,' said Mr Jan Jaap Brinkman, an engineer with Dutch consultancy Delft Hydraulics, who worked on the study. By 2025, estimates from the Inter-governmental Panel on Climate Change show, sea levels would have risen by only about 5cm. But Mr Brinkman said that Jakarta, which spans a plain between coast and mountains, will be between 40cm and 60cm lower than it is now. The study shows that without better defences, the sea will reach the presidential palace, which is around 5km inland, in 2025 as well as completely inundate Jakarta's historic old city.

Confidential reports on Lapindo mudflow leaked to wiki

Tuesday, August 3, 2010


Two confidential reports about Lapindo mudflow were uploaded to wikileaks. Here’s an excerpt from the wikileak page:

UK geologists downplayed Lapindo's argument and concluded that the earthquake was merely coincidental. While it could have generated a new fracture system and weakened strata surrounding the Banjar-Panji 1 well, it could not have been the cause of the formation of the hydraulic fracture that created the main vent 200 m (660 ft) away from the borehole. Additionally there was no other mud volcano reported on Java after the earthquake and the main drilling site is 300 km (190 mi) away from the earthquake's epicenter. The intensity of the earthquake at the drilling site was estimated to have been only magnitude 2 on Richter scale, the same effect as of a heavy truck passing over the area.

Jakarta flood and disaster management

Sunday, February 4, 2007

Most foreign media today says that the number of casualty for the Jakarta flood is 9. Local media however said that there are at least 20 dead. Thousands of civilians were trapped in flooded areas and need to wait for quite a long time before a rescue raft come to pick them up. But there wasn't enough raft for everyone. There should be enough rafts and boats if the armed forces were dispatched earlier to support the city police.

Communications are down, many telephone lines are off as the Telecom office is flooded by water, BTS antennas are also off due to electric cut. The flood had strucked down nearly all means of transportations from railways to toll roads. I think food distribution could be the next problem, in addition to the spreading of disease. I hope the officials have a clear chain of command in managing the situation although formally the disaster management law has not come into force.

Disaster management really should be a priority in the 2007 legislation program.
