Natural disasters in Indonesia can usefully be divided into major disasters, medium level disasters, and lesser disasters which although causing less damage are very common across Indonesia. These can conveniently be considered as macro, mezzo, and micro events. Policies to respond to natural disasters in Indonesia, which are still in an early stage of being developed, need to develop strategies to deal with each of these different types of disasters.
The official website of the Indonesian National Disaster Mitigation Agency (Badan Nasional Penanggulangan Bencana) provides frequent updates on disasters occurring in Indonesia.
The following is a list of main natural disasters that have occurred in Indonesia during recent history which have led to major loss of life (broadly defined here as over 500 deaths in the disaster).
(1) Total death toll unknown. The eruption is believed to have had a worldwide impact.
(2) This is the estimated death toll from the direct impact of the eruption. A total of perhaps 70,000 people are estimated to have died from starvation and disease in the area in the months following the eruption. See also 1815 eruption of Mount Tambora.
(3) "Some thousands" are reported to have died.
(4) Source: MCEER, University of Buffalo, The State University of New York, Major Indonesian Earthquakes of the 20th Century, accessed 29 December 2013.
(5) This is the estimated death toll in Indonesia. An estimated 60,000 more people died in other countries surrounding the Indian Ocean, especially in Sri Lanka.
(6) The original official death toll was around 2,200. However several thousands more, perhaps 4,000 or more, were buried in a major mudslide during the earthquake. It has therefore been difficult to compile a reliable estimate of the final toll. As of February 2019, it was estimated that over 4,300 died. [2]
In addition to the disasters listed in the table above, there are a large number of natural disasters in Indonesia which cause medium levels of loss of life (here defined, roughly, as between 50 and 500 deaths) or which give rise to large numbers of internally displaced refugees, sometimes for some months or more. Some recent examples of these include the following.
Note. Estimates of the numbers of evacuees can vary considerably in short periods of time. In some cases large numbers of people move away from a threatened area but return to their homes as soon as possible. It is often the case in Indonesia that people are reluctant to move away from their homes, or stay away long, because of worries about loss of property through theft and because of the need to look after local farms and cattle. Figures listed here are generally the peak numbers although sometimes different sources provide different estimates.
There is a large number of smaller natural disasters in Indonesia each year which often lead to deaths of 10 or 20 people or more. For example, landslides (tanah longsor) are very common in upland areas, especially during the rainy season, and cause much local damage and deaths. [6]
Flooding is also a regular problem across many parts of Indonesia. The capital city Jakarta is subject to severe floods from time to time which usually cause some loss of life and significant damage to public and commercial infrastructure. In January 2014, for example, over 20 people lost their lives during widespread flooding and at one stage over 60,000 citizens were temporarily housed in nearly 250 evaluation shelters across the city. [7]
In many rural areas, local flooding is very common and brings loss of life as well as much local inconvenience to economic and community life. Recent examples of these sorts of problems at the regional level include:
2014
According to the National Disaster Mitigation Agency (BNPB, or Badan Nasional Penanggulanan Bencana), as many as 566 people were killed by natural disasters and displaced over 2.6 million in Indonesia in 2014. Almost all of the disasters were classified as hydro-meteorological events. Tornadoes were the most common natural disaster (496 events) followed by floods (458 events) and landslides (413 events). Landslides caused the most deaths estimated at 343 people. [16]
Lombok is an island in West Nusa Tenggara province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" to the southwest, about 70 kilometres across and a total area of about 4,607.38 square kilometres including smaller offshore islands. The provincial capital and largest city on the island is Mataram.
West Nusa Tenggara is a province of Indonesia. It comprises the western portion of the Lesser Sunda Islands, with the exception of Bali which is its own province. The province's land area is 19,931.45 km2. The two largest islands by far in the province are the smaller but much more populated Lombok in the west and the much larger in area but much less densely populated Sumbawa island in the east. Mataram, on Lombok, is the capital and largest city of the province. It shares maritime borders with Bali to the west and East Nusa Tenggara to the east.
Mount Merapi, is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 km (17 mi) north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 m (5,577 ft) above sea level.
The National Agency for Disaster Countermeasure, abbreviated as BNPB, is the Indonesian board for natural disaster affairs. It was established in 2008 to replace the National Disaster Management Coordinating Board. BNPB is directly responsible to the President of Indonesia and the chairman is directly appointed by the President.
Mount Sinabung is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 40 kilometres (25 mi) from the Lake Toba supervolcano. Many old lava flows are on its flanks and the last known eruption, before recent times, occurred 1200 years before present, between 740 - 880 CE. Solfataric activities were last observed at the summit in 1912; recent documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013, January, February and October 2014. The volcano has recently claimed the life of at least 23 people in a number of events since 2014. Between 2013 and 2014, the alert for a major event was increased with no significant activity. On 2 June 2015, the alert was again increased, and on 26 June 2015, at least 10,000 people were evacuated, fearing a major eruption. The long eruption of Mount Sinabung is similar to that of Mount Unzen in Japan, which erupted for five years after lying dormant for 400 years. A major eruption began on 10 August 2020.
North Lombok Regency is a regency of the Indonesian Province of West Nusa Tenggara. It is located in the northwest of the island of Lombok and includes the offshore Gili Islands. The capital is Tanjung situated on the northwest coast of the island. The regency covers an area of 809.53 km2 and had a population of 200,072 at the 2010 Census and 247,400 at the 2020 Census; the official estimate as at mid 2023 was 265,500.
An earthquake occurred on September 2, 2009 at 14:55:01 local time in West Java, Indonesia. The magnitude 7.0 earthquake killed at least 81 people, injured over 1,297, and displaced over 210,000. The quake was felt in the capital Jakarta, although damage there was minimal, and it was Indonesia's deadliest earthquake since the 2006 Pangandaran earthquake and tsunami.
In late October 2010, Mount Merapi in border of Central Java and Special Region of Yogyakarta, Indonesia began an increasingly violent series of eruptions that continued into November. Seismic activity around the volcano increased from mid-September onwards, culminating in repeated outbursts of lava and volcanic ash. Large eruption columns formed, causing numerous pyroclastic flows down the heavily populated slopes of the volcano. The 2010 eruption of Merapi was the volcano's largest since 1872.
On 2 July 2013, an earthquake struck the Indonesian island of Sumatra on 2 July with a moment magnitude of 6.1 and a maximum Mercalli intensity of VI (Strong). The strike-slip earthquake killed at least 43 people and injured more than 2,500 others in the province of Aceh where approximately 4,300 homes were damaged or destroyed.
Mercy Relief is a Non-Governmental humanitarian organization based in Singapore. The organization was officially launched in 2003 by the then-Deputy Prime Minister of Singapore, Mr Lee Hsien Loong. Apart from responding to immediate disasters in the Asian region, its longer-term developmental projects also focus on water & sanitation, shelter, sustainable livelihoods, healthcare and education.
The following lists events that happened during 2014 in Indonesia.
The 2016 Aceh earthquake struck the Indonesian island of Sumatra with a Mw of 6.5 in Aceh province on 7 December 2016, at 05:03 WIB. The shock was reported to be at a depth of 13 km, categorized as a strong, shallow earthquake. The epicentre was located near the village of Reuleut in Pidie Jaya Regency, 164 km (102 mi) southeast of the province's capital, Banda Aceh. 104 people died in the quake, with at least 1,000 people injured. It was the deadliest earthquake in Aceh since the 2005 Nias–Simeulue earthquake and the deadliest in Sumatra since the 2010 Mentawai earthquake and tsunami.
2018 (MMXVIII) was a common year starting on Monday of the Gregorian calendar, the 2018th year of the Common Era (CE) and Anno Domini (AD) designations, the 18th year of the 3rd millennium and the 21st century, and the 9th year of the 2010s decade.
On 5 August 2018, a destructive and shallow earthquake measuring Mw 6.9 struck the island of Lombok, Indonesia. It was the main shock following its foreshock, a nearby Mw 6.4 earthquake on 29 July. It was followed by a nearby 6.9 earthquake on 19 August 2018.
Sutopo Purwo Nugroho was an Indonesian civil servant and academic who worked at the Indonesian National Board for Disaster Management as its head of public relations.
Tropical Cyclone Cempaka was a tropical cyclone that impacted the island of Java and Bali, Indonesia in November 2017. Although it did not make landfall, Cempaka managed to cause 41 deaths, with more than 20,000 people evacuated and causing around US$83.6 million in damages. Cempaka was the fourth cyclone to be registered in Indonesia by the Tropical Cyclone Warning Center of the Indonesian Meteorology, Climatology, and Geophysical Agency (BMKG) since 2008 and the first since Cyclone Bakung in 2014. It also came closer to making landfall in that country than any other cyclone on record.
On 22 January 2019, floods caused by heavy rainfall struck the Indonesian province of South Sulawesi. At least 68 people were killed and thousands were displaced. Gowa Regency was particularly hard-hit, experiencing the majority of the fatalities.
