Tectonic setting
The island of Bali forms part of the Sunda Arc, which formed above the convergent boundary where the Australian plate is subducting beneath the Sunda plate. The rate of convergence across the line of the Sunda–Java Trench is 7.5 cm per year. Eastwards from Bali, the Sunda Arc is also being thrust over the Bali and Flores back-arc basins on a series of south-dipping thrusts. Focal mechanisms for earthquakes near Bali are dominantly thrust sense on both the subduction interface and the system of thrust faults to the north.McCaffrey R.

A previous earthquake of 6.6 s y southeast of Bali on 21 January 1917 had caused 1500 casualties on the island. A subsequent earthquake of 6.5 s southeast of Karangasem Regency on 18 December 1979 caused 27 deaths on the island and displaced a similar number of people as the 1976 event.

According to the United States Geological Survey (USGS), the 14 July shock occurred 915 km on east-southeast of Jakarta at a depth of 25.4 km on although the hypocenter may actually have been as deep as 40 km on. The main shock lasted for a duration of nearly a minute. Several fumaroles reportedly formed in the Yeh Kuning sub-district of Jembrana and released sulfurous fumes. The Jakarta Geophysical Service initially believed the epicenter to be in the Bali Strait, some 25 km on west of the location observed by the USGS. A subsequent shock of 5.9 s occurred at 18:23 local time on 14 July 10:23 GMT 14 July a short distance north, although the hypocenter was at a more shallow 16.3 km on.USGS ShakeMap Atlas (Version 1.0) – 1976-07-14-1023 https://earthquake.usgs.gov/earthquakes/shakemap/atlas/shake/197607141023/ United States Geological Survey 12 June 2015 November 4, 2008
Damage
According to data from the 1971 census, over nine hundred thousand people resided in the three regencies of the island that suffered significant structural damage and fatalities as a result of the shock; Buleleng, Jembrana and Tabanan. At least 85,500 dwellings and 226 schools were destroyed within the three regencies, in addition to serious damage to 86 government offices, 29 health facilities, 7 markets, and dozens of religious sites. The epicenter was only a few kilometers north of Seririt, a town with a population between forty and fifty thousand people and at that time the 3rd most populous in Bali.220 killed as quake hits Bali https://news.google.com/newspapers?id=WfxjAAAAIBAJ&pg=4666%2C4404911 12 June 2015 AAP The Sydney Morning Herald 16 July 1976 Early reports by Reuters described Seririt as being 'flattened' and that '[sic] almost all the buildings in the town and bridges collapsed'.52 killed in Bali earthquake http://nla.gov.au/nla.news-article110817575 13 June 2015 AAP & Reuters The Canberra Times 16 July 1976
In the first few days, international media focused in particular on the plight of up to 200 school children who were reportedly trapped by the collapse of a single school building within Seririt town; the bodies of ten children were recovered on the day of the main shock, and another six bodies were reportedly recovered in following days.Bali earthquake takes 223 lives, injures 2350 https://news.google.com/newspapers?id=DcAaAAAAIBAJ&pg=5323%2C1976623 13 June 2015 Associated Press Daily News 15 July 1976In brief; Earthquake http://nla.gov.au/nla.news-article110817877 13 June 2015 AAP The Canberra Times 19 July 1976 More than 60 students died in the collapse of this particular school, however the exact name of the school remains unclear.Arya Dr. Anand Consultant report on field survey of natural disasters http://www.preventionweb.net/files/5321_FieldSurvey3CountriesArya.pdf preventionweb.net United Nations Centre for Regional Development 8 13 June 2015 August 2002
The only Buddhist monastery in Bali, the Brahma Vihara Arama in Banjar village 4 km on from Seririt, was severely damaged.
Damage to infrastructure in Busung Biu and other mountainous sub-districts meant that personnel of a Singapore Armed Forces (SAF) Medical Relief mission had to trek into mountain towns by foot, carrying supplies by hand. During the mission, the Singaporean team reportedly experienced three further damaging tremors.Earthquake, Bali, 1976 http://www.mindef.gov.sg/imindef/mindef_websites/atozlistings/safmc/Latestopsdeployment/EarthquakeBali.html Singapore Ministry of Defense Singapore Armed Forces Medical Corps 13 June 2015
Although Seririt and rural sub-districts of Buleleng were most severely affected, a 60-bed hospital in the town of Negara was also completely destroyed. The Taman Ujung historic site in Karangasem was also extensively damaged, exacerbating damage already caused by earthquakes associated with the volcanic eruption of Mount Agung in 1963.Yudantini Ni Made Balinese traditional landscape http://download.portalgaruda.org/article.php?article=13280&val=928 Faculty of Engineering, Udayana University 13 June 2015 https://web.archive.org/web/20150616005547/http://download.portalgaruda.org/article.php?article=13280&val=928 16 June 2015 dead It was felt in the Kuta and Denpasar areas, but only minor damage resulted.
Relief effort
Indonesian Red Cross and Red Crescent (IRCS) and local government joint relief activity, led by the governor of Bali and operated from a provincial relief control center, largely met the emergency needs of the victims within four days. In-country contributions, both in cash and in kind, amounted to more than US$900,000.
