The quake left residents of Padang, on the west coast of Sumatra, panicking for a moment.
Nuclear Reactors In the Area
For research purposes, the following experimental nuclear reactors have already been built in Indonesia:
Kartini nuclear research reactor in Sleman, Daerah Istimewa Yogyakarta
The operation of the Kartini reactor since 1979 until 2013 has given considerable experiences in accordance to its purpose of design. The licensing of the Kartini reactor has reached its final status in December 2010, modifications have been conducted in the year 2013 and obtained further licensing for operation until December 2019.
MPR RSG-GA Siwabessy nuclear research reactor in Serpong, Banten
Reaktor Serba Guna–Gerrit Augustinus Siwabessy (RSG-GAS) (Multipurpose Reactor–Gerrit Augustinus Siwabessy) is a research reactor located in the Serpong neighborhood of South Tangerang, Banten, Indonesia. The reactor plays an important role in the Centre for Nuclear Industry Development, at Puspiptek, Serpong to serve other supporting laboratories, namely, radioisotope production, nuclear material science, reactor fuel element development, reactor safety, waste treatment, radio-metallurgy and nuclear-mechano laboratories.
The reactor was constructed through a $50 million contract with Interatom Internationale Atomreaktorbau GmbH, a unit of the West German steelmaker Kraftwerke Union, which was awarded in 1981.
The reactor’s fuel rods have originated in the United States, France and the United Kingdom; the fuel was enriched in the United States and Russia. The International Atomic Energy Agency safeguards the reactor. It was inaugurated by the second President of Indonesia, Suharto on August 20, 1987. The reactor was named after G.A. Siwabessy, Minister of Health and Minister of Atomic Energy under both president Sukarno and Suharto.
RSG-GAS went to its first criticality on July 29, 1987. The nominal power of 30 MW thermal was achieved on March 23, 1992 at the sixth core containing 40 standard fuel elements and 8 control fuel elements

“It was very scary. This is the second quake we felt today. Our house was shaking, so we ran outside,” Ira, a resident of Padang told AFP. Indonesia is one of the most disaster-prone nations on Earth due to its position straddling the so-called Pacific Ring of Fire, where tectonic plates collide.
Mentawai was hit by a tsunami in 2010 which killed more than 400 people and Padang suffered from a deadly earthquake in 2009 where more than 1,100 lives were lost. Last year, the Indonesian archipelago was hit by an earthquake and tsunami in Palu on Sulawesi island which killed around 2,200 people. At the end of the year, an erupting volcano in the middle of the Sunda Strait between Java and Sumatra islands killed more than 400 people.
