Type of eruption;
Based on the historical record of the eruption of mt. Iya, the shortest rest period of 1 year and the longest 173 years, the last eruption occurred on January 27, 1969. The type of eruption of Mount Iya based on geological data and its history is eruption explosive and efusif. Such type of eruption has the potential to produce pyroclastic deposits and lava. The eruption activity of Mount Iya is accompanied by hot clouds, pyroclastic flows, pyroclastic fall, volcanic bombs, incandescent rocks, heavy ash rains, and lava flows (primary danger) and landslides or lava (secondary danger)…
Topology & Geology;
Product eruption from mt volcano complex Yes formed a headland in southern P. Flores. Mt complex. Yes consists of mt. Pui (table mt) with a height of 371 mdpl, mt. Roja with 425 mdpl and mt. Yes. The three volcanoes are located in a straight line, mt. It is located in the southwest and mt. Pui to the east. Stratigrafi area mt. Yes from the oldest to the youngest as follows:
– Pre Roja Rock (Tertiary)
– Rock erupted results mt.Roja
– Rock erupted results mt.Pui
– Rock erupted results mt.Iya
– Alluvial deposits
Mt morphology area Yes and its surroundings can be identified into four units, namely Morphology of Tertiary Volcanic Hills, Roja Complex Morphology, Morphikic Cone Cone and Ground Morphology. Morphology mt. Yes and mt. Pui forms a volcanic cone morphology of Iya whose formation is dominated by the building process, while mt. Roja shows the morphology of volcanic inscribed. mt. Pui is a natural fortress against the threat of mt eruption. Yes for the city of Ende.
Complex structure mt. Yes is a normal faults that exist between mt. Roja and mt. Yes, northeast-southeast direction with the southern block is relatively down. In addition to the fault structure, there is also a north-west-northwest direction that connects the eruption points of mt.Iya, mt.Roja and mt.Iya.…
