Jakarta prepares earthquake microzonation map

Jakarta, Indonesia: The Jakarta government is preparing an earthquake microzonation map. The map, drafted together with the National Earthquake Map Revision (RPGN) team, is expected to serve as a guideline for earthquake detection and mitigation.

“The map will identify the susceptibility levels of each area in the capital city as a mitigation step,” said Fauzi Bowo, Governor, Jakarta.

Based on recent scientific data presented by the RPGN team, Jakarta has been judged relatively safe from tremors. RPGN team head, Prof. Masyhur Irsyam, said that in terms of earthquake history in Indonesia, Jakarta was quite safe. However, he added that Jakarta would still be affected by earthquakes with epicentres in neighbouring areas.

In addition, Masyhur said there were at least 10 locations that were prone to earthquakes, namely Sumatra, Java, Sunda, Semangko, Sukabumi, Baribis, Lembang, Pati, Bumi Ayu and Yogya or Opak.

The earthquake-resistant building regulation is safe as it passed the Indonesian national standard (SNI), which has been renewed in accordance with the International Building Code (IBC), he added. Jakarta Building Supervision and Order Office head, Hari Sasongko, guaranteed that buildings taller than eight stories in Jakarta were safe from earthquakes exceeding more than 8 on the Richter Scale.
