Abstract
Volcanoes located over carbonate-rich sedimentary
rocks often emit large volumes of CO2 and have strong
records of explosive activity. Examples include Vesuvius
and the Colli Albani volcanic field in Italy;
Popocatepetl in Mexico; and Merapi in Indonesia, all
of which display petrological and/or gas-chemical
evidence for magma-carbonate interaction. Merapi is
one of the most active volcanoes in Java (Fig. 1), and
represents a serious hazard by being located less than
30 km from Yogyakarta, the largest city in Central
Java with a population of about 3.5 million. In this
article, we discuss the outcome of recently-published
experimental results demonstrating that CO2 can be
released through a magma-carbonate interaction
more rapidly than had been previously expected. As
carbonate rocks are considered to be an important
source of the volcanic CO2 at Merapi, and because
they are also a potential influence on eruption dynamics,
understanding the timescales of crustal CO2
degassing is important in improving eruption forecasting
at carbonate-hosted volcanoes.
