West Bandung
landslides put Cipularang toll road at risk

The Cikampek-Purwakarta-Padalarang (Cipularang) toll road at
kilometer marker (KM) 118 is at risk from landslides that have occured at
Sukatani village, West Bandung regency, West Java.
The land movements have occurred since mid-December 2019, yet the
colossal displacement that damaged at least six houses happened on Tuesday, at
around 10 p.m.
Earth researcher, Anjar Heriwaseso, from the Center for
Volcanology and Geological Hazard Mitigation (PVMBG), said it would be better
for the residents in the area to stay alert, as there was still the possibility
of more land movements.
“The early mitigation that is being carried out is focused on
draining puddles around the location. After they are drained, then [we] can do
other structural-mitigation measures, such as slope containment and terracing
[soil conservation],” said Anjar, who was gathering ground-surface data and
aerial photographs from the location of the landslides on Wednesday.
Head of community unit (RW) 04, Sukatani village, Wahyudin,
explained that a landslide, which flattened two resident’s houses, started at 7
p.m. and got worse over the next two hours. The ground movement caused the soil
to pile up to dozens of meters in height.
“Two houses were destroyed and four were heavily damaged,”
Wahyudin added.
In regard to the threat level, Wahyudin explained that there were
still around 80 families residing in the area.
According
to provisional field analysis, Anjar said that a possible cause of the
landslide was a large puddle that formed due to a blockage at the
drainage channel across the toll road. He had yet to come to the
conclusion as to whether the puddle was located along the valley of the initial
landslide location point. The distance between the point to the toll road is
approximately 10 meters.
“Mitigation through draining this water puddle has to be done
immediately. [We are] worried that the cliff of yesterday's landslide will
[approach] the toll road. It needs to be continuously monitored,” Anjar said,
adding that drones were used to help conduct aerial surveillance.
“Ground surface [analysis] to check the condition of the rocks,
the structure of the soil, the land formation and irrigation system in the area
is all in process. Meanwhile, drones [are being used] to confirm delineation,
observing land movements,” Anjar said, explaining that data on the landslide
location before the toll road was constructed had to be checked as well to
understand its historical structure.
Future land movements were still possible, Anjar noted, especially
with the 22-degree steep slope.
“If the slope is disturbed, automatically it will cause [land]
movements. If we look at it now, there are numerous disturbances, for example,
the changing land use and the movement of heavy vehicles on the toll road,” he
said. (ydp)

An eruption
rocked Mount Merapi volcano, which stands on the border of Yogyakarta and
Central Java, at 5:16 a.m. on Thursday morning.
“The
eruption lasted 150 seconds, spewing smoke and 2,000-meter-high ash column,”
National Disaster Mitigation Agency (BNPB) spokesperson Agus Wibowo said in a
statement on Thursday.
He added
that during the eruption, the wind was blowing in a northwest direction,
according to the Geological Disaster Technology Research and Development Center
(BPPTKG).
In a
separate statement, BPPTKG head Hanik Humaida said the eruption spewed volcanic
material over a radius of 1 kilometer from Merapi’s peak. It also brought ash
rain down on several villages located 10 km south of the volcanoThe BPPTKG
added that Mount Merapi had erupted four times between September and November
2019, followed by volcanic earthquakes occurring at a depth of more than 1.5
km.
“There has
been an increase in Merapi’s volcanic activity from mid-December 2019 to
mid-January this year, both under and on the ground,” Hanik said in the
statement. “Similar eruptions can still happen in the future as an indicator
that the magma chamber is still supplying magma.”
Mount
Merapi is one of the most active volcanoes in Indonesia. An eruption in 2010
left more than 300 people dead and forced almost 400,000 people to take refuge.
Authorities have raised Merapi’s alert level to waspada (caution), the
second-highest level in the country’s four-tiered alert system.
The
Volcanology and Geological Hazard Mitigation Center (PVMBG) has advised
residents and tourists to stay outside a 3-km radius of the peak of Merapi to
avoid any possible danger.
