LIQUEFACTION SHIFTED JONO OGE TO LANGALESO

Few minutes after an earthquake struck

Palu, Central Sulawesi, there came out

huge mud bursts in the upper location,

in the border of Sidera village and Jono

Oge village that are located in Dolo

sub-district, Sigi district. In the beginning

they were water bursts, however, slowly it

became robust liquid soil bursts.

“The liquid soil is rolling like it’s inside

a food blender,” expressed Abdul (40),

who lives in 3 hamlet, Langaleso village,

to Kareba Palu Koro team on Wednesday

(25/10) in the 3 hamlet evacuation post.

Langaleso village is one area that does

not only get impacts from the earthquake,

but also from the soil liquefaction.

The other areas that suffer from the

liquefaction are Petobo and Balaroa in

Palu.

Liquefaction that happened sometime

after the 7.4 SR earthquake, hit those areas

on Friday afternoon, 28th September 2018

and it caused a sudden soil movement

shift from Jono Oge Village to Langeleso

village which is about 3 kilometers away.

Most of the areas in 3 hamlet, Langaleso

village were covered evenly by soil. Trees,

base transceiver towers were carried away

or shifted, the community settlements,

mosques and churches also experienced

the same thing.

“There were about 200 school children

who carried away by the liquid soil and

buried underneath the mud in a church

because they were having an activity

there during the event,” said Abdul.

It’s an Indonesian Protestant Church in

Donggala. When we visited the location,

the community shared that they were still

some students’ parents who came to look

for their children.

The other community members met in

some evacuation points also shared the

same things about what happened in their

hamlets.

The bursts looked like that they

exploded first, then the water burst out,

seemed like boiling water,” said Suwarti

(38 years old).

Luckily they ran to the right direction and they didn’t get the

liquefaction impacts and they were safe.

According to Dr. Yusuf Surachman Djajadihardja, PhD, a senior

researcher of the Assessment and Application of Technology

Agency (in Indonesian BPPT), the liquefaction occured because

the water saturated sand layer below the ground surface in the

area changed into liquid soil when the earthquake happened and

triggered landslide.

Currently the community members are staying in the 2 village

evacuation post that is located in a field and the 3 hamlet

evacuation post which is located on the road sides and rice field

areas nearby the liquefaction affected area. The number of the

people who are impacted are 311 households and mostly from

3 hamlet. At the moment they are living in tents. Each tent is

occupied by two up to three households.

Although they have received some assistances, however, their

logistic supplies are decreasing. From the aids that they’ve received,

more aids come from the non-government organizations.

Up to now, according to Aziz, the 3 Post Coordinator, there is no

any plan yet from the government related to the Langaleso Village

cleaning or ground flattening measures.

The ERCB network has plans to do rice distributions and also

to provide health service and trauma healing. The ground for

providing a health service is because there are a lot of health

problem reported by the earthquake impacted community such

as itches as they all do water sanitation activities in the same water

source. Besides those measures, the team also see the possibility to

do WASH and temporary shelter interventions.

The community main expectation for the future is to have their

houses again, although it means they have to be relocated. They

also hope that the economy life may go as usual and they can

return to work and earn some income to support their families.

Three tons of rice were sent by the Emergency Response Capacity

Building Network (ERCB) to Mamboro kelurahan on Thursday

(25/10). The rice distribution is part of the ERCB Network activity to

help the earthquake, tsunami and liquefaction survivors in Central

Sulawesi.

The organizations that involve in the ERCB network are LPTP,

Bina Swadaya, Perdhaki, Pusaka Indonesia Foundation and

AMAN. In Central Sulawesi, the network is working with two

local organizations, they are KARSA Institute and Merah Putih

Foundation (YMP). The planning for the next three months is that

they are going to provide assistance in a form of food and non-

food items such as water and sanitation, health service, temporary

shelter, children learning and playing spots.

RICE DISTRIBUTION TO MAMBORO

The rice distribution in Mamboro kelurahan, Palu Utara sub-

district, Central Sulawesi targeted the survivors who are staying

at the evacuation post. Abdul Ghofur (36 years old), the Post

Coordinator, received the rice and it’s directly distributed to

120 households from the total registered 180 households. Each

household received 25 kilograms of rice. The rest of 60 households

who haven’t received the rice would be validated first.

The community in that village temporarily moved to a post which

was located in a higher location because almost all of their houses

were carried away by the tsunami that followed by earthquake on

28th September 2018.

The household number validation is required to ensure that the

aids is distributed to the correct targets, i.e. for them who do stay

in the evacuation point and are the community members of the

village. The increase number of the internally displaced people is

probably there are people who previously stayed in evacuation

points outside Mamboro then they’ve returned to Mamboro

kelurahan.

The rice distribution is becoming an entry point to get an

accurate data related to the number of beneficiaries and the type

of the aids that will be distributed. Based on the plan and the early

assessment done, the type of aid that will be distributed to an

impacted village will possibly not limited to one type of aid. Besides

rice, the ERCB network will give additional aid in the form of food,

waste bins and palettes for the tents base. (mdk)

KAREBA PALU KORO

Located in the Palu Independent Journalist Alliance parking lot, on Saturday (27/10), a discussion was organized to do a reflection, one month post the earthquake, liquefaction and tsunami that hit Palu, Donggala and Sigi. Dr. Yusuf Surachman Djajadihardja, PhD., attended the event as a speaker. He is a senior researcher for the Technology Assessment and Research Agency (in Indonesian BPPT). The Central Sulawesi Governor, Drs. Longki Djanggola, M.Si, also joined the discussion.

During the discussion, it was presented

the information about tectonic plates and

faults exist that Indonesia has. In 2002,

Yusuf got the opportunity to do a research

on Sumatera fault that lies at 2,012 meters

depth under the sea level. The observation

showed that the fault runs lengthwise up

to the southern part of West Java.

“The existence of that fault brings

up a debatable prediction about a big

earthquake that may strike the western

part of Sumatera until Java, especially

Jakarta. It’s estimated that the earthquake

will reach 8 SR. The prediction on when

and the scale of the earthquake are based

on the calculation of the annual plate

movement,” explained Yusuf.

Yusuf explained that the earthquake

happened in Central Sulawesi on 28

September 2018 was the result of the Palu

Koro fault activity that was triggered by

the horizontal fault structure shifting to

the left direction. This were able to happen

because the fault in Sulawesi area is a

shifting fault type.

Soil Liquefaction in Balaroa Village

Regarding the soil liquefaction, Yusuf

presented about what happened in

Balaroa village. The soil thickness in one

point in that area was only 5 meters.

Underneath the soil there were stones and

sands aggregate layers which alternated

between the coarse ones and the fine

ones. There was an underground structure,

called aquifer structure or rock structure

that was saturated by water.

“During the earthquake, the structure

was shaken and the sand layers turned out

into liquid soil,” said Yusuf.

The condition in Balaroa, just like in

Petobo Village and Jono Oge Village

that are located in an elevation, caused

a landslide and it looked like the soil was

sliding because the particles binding

underneath was loose and became liquid/

mud.

The liquefaction process was illustrated

by a video that showed how a sand surface

on a coastal line that was formerly dense,

however, when a bar of wood stabbed

into it and the bar was moved repeatedly

horizontally and vertically, the dense

surface turns out into an unstable and

loose liquid soil.

Disaster Risk ReductionOne of the people who asked questions,

Neni Muhidin, from the Disaster Risk

Reduction Forum, Central Sulawesi,

reminded the importance of disaster risk

reduction because they live in a disaster

prone area.

“The risk can be calculated. We should

know that the hazard is real. We must

understand our vulnerabilities, but we

should also know that we have capacities

to rise up,” she said.

She also criticized the spatial

management policy in Central Sulawesi,

about the contingency plan which has not

been renewed and the preparedness level

of the Regional Disaster Mitigation Agency

(in Indonesian BPBD).

The discussion was closed by Governor’s

statements about Central Sulawesi spatial

management change that has been

planned by taking into account the disaster

that has just happened and also its future

planning. The government put some

efforts in order the spatial management

change planning will finish in this

December. (mdk)

WATER, SANITATION AND CLEANNESS BECOME A CONCERN

During the ERCB team coordination meeting

on Monday, 22th October, there were findings

related to water, sanitation and health. The

meeting aimed to confirm the ERCB team

intervention that would be implemented soon.

The regional drinking water company (in

Indonesian PDAM) network experiences 80%

damage. The PDAM is still taking data for the

purpose of public hydrant provision in several

spots. Based on the investigation conducted

by the Health Ministry team, from the 33 water

samplings, 22 among them consist of E. Coly

bacteria.

“For that reason, the team is trying to

neutralize the E. Coly bacteria contaminated

water by putting a kind of tablet in each water

source where the water samplings were taken,”

said Agung Prasetia from Bina Swadaya, one of

the ERCB members.

The Joint Secretariat for Central Sulawesi

WASH (water, sanitation and hygiene) Sub

Cluster has been established to manage an

integrated data related to clean water service,

sanitation service, health promotion. The data

can be accessed in www.Sekberwashsulteng.id.

Another note from ERCB team gained from

the WASH Cluster meeting is the available

bathing, washing and latrine facilities (in

Indonesian MCK) in some evacuation points in

Palu that are starting to have problems.

The problems emerge because of the

community behavior - they dispose garbage

into the latrines and clog the drains. There

is an initiative to print stickers that invite the

community not to put garbage into the latrines.

The other initiative is to form a team who is

responsible to take care of the MCK facilities.

“The community also use the latrine

facilities for having shower. This causes the

absorption gets full rapidly. If it overflows, it

may become a source of disease. The design is

not handicapped accessible also become our

thought,” said Sutikno, the ERCB coordinator.

The garbage service carriers had not fully

operated and caused piling up of garbage and

attracted a big number of flies. However, one

month after the earthquake, some of the carriers

have started their works but there are not too

many yet.

“We will try to coordinate to each other,

especially for the medical disposal, we will

coordinate with the local community health

center (in Indonesian Puskesmas),” Sutikno

continued his explanation. (mdk)
