Powerful flows of volcanic mud carried by rivers from Mount Merapi that have destroyed bridges, houses, farmlands and other structures along river banks also pose a threat to the Prambanan Temple.
The famous Hindu temple complex, located in Prambanan on the border of Yogyakarta and
Central Java provinces, sits 100 meters from the banks of the Opak River, a confluence of the Petit Opak and Gendol Rivers that flow from Mt. Merapi.
Prambanan, a ninth-century Hindu temple compound — a UNESCO World Heritage Site — is the largest Hindu temple in Indonesia and one of the largest Hindu temples in Southeast Asia.
In 1006, large eruptions on Mt. Merapi covered the Buddist temple of Borobudur in Magelang, Central Java, in ash, where it lay hidden for centuries under ash and jungle growth.
An official from the Volcanic Technology Development and Research Center (BPPTK) in Yogyakarta, Dewi S. Sayudi, said the threat to Prambanan was immense because the upper streams of both the Opak and Gendol Rivers carried large amounts of volcanic debris from the 2010 Mt. Merapi eruptions.
“The lahar that we have seen so far is just the tip. The flows carry only a small portion of the thick layers of volcanic debris from the slopes of Merapi,” Dewi said recently.
The eruptions in October and November, Merapi’s most powerful in a century, were estimated to
have spewed more than 150 million cubic meters of volcanic debris consisting of large rocks, stones, sand and ash.

Yogyakarta’s Temples in the Firing Line of Lahar Floods
18 jan. 2011 | The Jakarta Globe by Candra Malik
Yogyakarta. Lahar, the cold volcanic debris flowing down the slopes of Mount Merapi, is not only threatening houses and infrastructure but also archeological sites, a geologist said on Tuesday.
Subandrio, head of the Volcano Investigation and Technology Development Institution (BPPTK), said a team of geologists and archaeologists was evaluating the physical condition of temples located near the paths of the lahar runoff from Merapi.
“According to a letter from the Archaeological Heritage Conservation Center of Central Java, we have to give particular attention to the safety of Prambanan Temple and other temples in the complex,” he said.
