Security threats

On 21 January 1985, nine stupas were badly damaged by nine bombs. In 1991, a blind Muslim preacher, Husein Ali Al Habsyie, was sentenced to life imprisonment for masterminding a series of bombings in the mid-1980s, including the temple attack. Two other members of the Islamic extremist group that carried out the bombings were each sentenced to 20 years in 1986, and another man received a 13-year prison term.

On 27 May 2006, an earthquake of 6.2 magnitude struck the south coast of Central Java. The event caused severe damage around the region and casualties to the nearby city of Yogyakarta and Prambanan, but Borobudur remained intact.

In August 2014, Indonesian police and security forces tightened the security in and around Borobudur temple compound, as a precaution to a threat posted on social media by a self-proclaimed Indonesian branch of ISIS, citing that the terrorists planned to destroy Borobudur and other statues in Indonesia. The security improvements included the repair and increased deployment of CCTV monitors and the implementation of a night patrol in and around the temple compound. The jihadist group follows a strict interpretation of Islam that condemns any anthropomorphic representations such as sculptures as idolatry.
