Landsat interpretation and detailed field observation were conducted to <br>find out the eruption activity, the conduit system, and the host rock. Both physical and chemical properties of <br>erupted material were tested to track down the mud origin, movement dynamic, and changes during <br>transportation. Active bubbling which bring fluid, claystone- to sandstone-size solid particles, gas, and heat as <br>well as crusting material inside conduits are detected in Ciuyah. The high similarity of rock composition and <br>fossil contained indicated that the mud comes far below the surface passes the rock layers of the Late Tertiary <br>sedimentary rock (Pemali and Halang Formations), and then ejected to the surface through conduits. The <br>temperature of extruded mud reaches 6.9° to 13.6° compared to air temperature (hyperthermal). Conduits where <br>the mud comes out mostly show NW-SE direction as a minor pattern of existing morphological lineament <br>directions. Changes seen in pH, TCD and EC, besides hydro-chemical composition (level of Na+<br>, Cl-<br>, SiO2,<br>Mn2+, K+<br>, Li+<br>, Fe3+, Mg2+<br>, HCO3<br>-<br>, Ca2+ and SO4<br>-<br>) caused by water formation as well as minerals enrichment <br>dissolved due to heat and long-time contact to the side rock during eruption.<br><br></p>}, number={75}, journal={GEOMATE Journal}, author={Vijaya Isnaniawardhan and Nanda Natasia and Titin Kartina Effendi and Boy Yoseph Cahya Sunan Sakti Syah Alam4 , Ismawan and Nana Sulaksana}, year={2020}, month={Nov.}, pages={92–99} }
