April 12, 2012. he massive earthquake off Indonesia rattled investors and sparked fears of a fresh crisis in coal supplies to the beleaguered domestic power sector. Some Indian power firms have coal supply agreements with Indonesian firms and investors fear that operations will be affected in case of large-scale damage. Tata Power, Adani Power and Reliance Power have bought coal assets in Indonesia to fuel their projects in India, while others like JSW Energy and Lanco Infratech have fuel supply pacts with miners and traders there. A powerful earthquake followed by an equally massive aftershock hit Indonesia, triggering tsunami warnings in 28 countries and reviving memories of the dreadful Boxing Day tsunami of 2004 which killed about 2.3 lakh people.
