A. Situation analysis
Description of the disaster A 6.4 magnitude earthquake struck off Lombok, province of West Nusa Tenggara, Indonesia, at 05:47h local time, on Sunday 29 July 2018, followed by multiple aftershocks, with the highest magnitude of 5.7 (data released by BMKG at 23:00h local time, 29 July 2018). The earthquake affected five districts: North Lombok, East Lombok, West Lombok, Central Lombok and Mataram, with 14 deaths reported to date, at least 135 people injured and 14,706 displaced, damaging many buildings and homes (assessment is underway and fixed figures to be shared soon). According to the US Geological Survey (USGS), the quake was centered 50 kilometers northeast of the city Mataram on the northern part of Lombok island, with a depth of 10 km. Indonesia’s agency for meteorology climatology and geophysics (BMKG) indicated that there was no risk of a tsunami. The quake also impacted Mount Rinjani national park, a popular trekking destination. Access to the climbing routes are temporarily closed due to reports of a landslide around the mountain. A total of 820 mountain climbers – 617 foreigners and 203 locals – were stuck within the area of Rinjani, with 554 people evacuated and the remainder in the process of being evacuated.
The BNPB and the regional disaster management agency (BPBD) are coordinating the response and collating information on the earthquake’s impact. Initial reports indicate that the earthquake’s impact on infrastructure in two out of five affected districts resulted to damages to some 1,128 houses and a small number of public facilities such as health centres, mosques and schools. These numbers are expected to increase as assessments continue for the other three affected districts. There has also been some damage to main roads, resulting in constraints to accessing some of the affected areas, as well as disruption to communication lines in some affected areas.
Search, rescue and retrieval efforts are underway, with hundreds of villagers and multi-agency teams, including personnel from Palang Merah Indonesia (PMI), National Search and Rescue Agency (BASARNAS), BNPB, BPBD, Indonesian National Police (POLRI), Indonesian National Armed Forces (TNI) and local government agencies involved.
Assessments as well as delivery of immediate assistance which includes first aid and basic medical services are also being undertaken alongside search, rescue and recovery efforts.
The Government of West Nusa Tenggara Province has issued a provincial level state of calamity to be applied for three days until 1 August 2018, and the district of Lombok until 5 August, with potential extension following the result of continuous assessment on the impact and development of the situation. BNPB has indicated that there is no request for international assistance at this stage.
