    BPBD: There is a lot of new landslide material from the top of Mount Merapi

    UMMAT DAILY ■ The Quick Reaction Team, Regional Disaster Management Agency (BPBD) of the Special Region of Yogyakarta Province monitored the latest developments in Mount Merapi's activity by air using a helicopter, on Friday (27/11).

    This activity is carried out in order to monitor the area so that further steps can be taken in relation to disaster mitigation for people living on riverbanks that are upstream on the slopes of Mount Merapi.

    "For us, as an evaluation material for community mitigation on the riverbanks upstream on the slopes of Mount Merapi," said Endro Sambodo, BPBD DI Yogyakarta TRC Team to the media crew, today.

    As for the results of the aerial monitoring, Endro said that there was a lot of new landslide material from the top of the mountain.

    "At first glance, there are many new landslide materials," said Endro.

    According to him, the landslide led to a slope which predominantly headed west and southwest.

    Meanwhile, seen from the morphology of the landslide material, it leads to the upper reaches of Kali Senowo, Kali Putih and Kali Lamat.

    Endro also reported that for the southwest region, there are some materials that are on the slopes leading to the upper reaches of Kali Boyong and Kali Krasak.

    Meanwhile, the southeast side upstream of Kali Gendol has seen an avalanche of new material. Preliminary estimates of the landslide originate from a crater on the western wall.

    For further study, TRC BPBD DIY then reports the results of the monitoring to the Center for Geological Disaster Research and Technology Development (BPPTKG) for further analysis.

    Previously, the head of the BPPTKG Hanik Humaida found traces of avalanche material from the 1998 eruption of Mount Merapi on the west side leading to Kali Senowo and Kali Lamat, as well as the remaining lava from the 1948 eruption, while conducting aerial monitoring using a BNPB helicopter on Thursday (26/11).

    Hanik also saw an avalanche of old material in the craters from the outside and towards the west side.

    "From the air monitoring, it can be seen traces of avalanche material on the west side, namely in the 1998 Lava (remnants of the eruption) which led to the upper reaches of Kali Senowo and Kali Lamat, as well as in Lava (the rest of the eruption in 1948," said Hanik.

    Based on provisional predictions from observations, according to Hanik, the potential danger still leads to the Gendol River.

    Hanik estimates that this year's avalanche of material from Mount Merapi's activities could potentially lead to the upstream flow of Kali Senowo and Kali Lamat. However, his party has not been able to determine with certainty the direction of the flow.

    "That old material fell to the northwest, namely the Senowo River and the Lamat River, but it is still upstream. As for the potential danger, the direction is still to the Gendol River," explained Hanik.
