It was the most powerful earthquake globally since the 2004 Indian Ocean earthquake three months prior, and is tied with the 2012 Indian Ocean, 1957 Andreanof Islands, 1950 Assam–Tibet and 1946 Aleutian Islands earthquakes as the tenth-largest earthquake ever recorded by seismometers.Search earthquake catalog United States Geological Survey https://earthquake.usgs.gov/earthquakes/map/?extent=-88.23373,-247.5&extent=88.23373,607.5&range=search&sort=largest&timeZone=utc&search=%7B%22name%22:%22Search%20Results%22,%22params%22:%7B%22starttime%22:%221900-01-01%2000:00:00%22,%22endtime%22:%222026-07-02%2023:59:59%22,%22minmagnitude%22:8.5,%22orderby%22:%22time%22%7D%7D 2 July 2026 The earthquake killed at least 1,600 people and injured over 9,300 others. Of the fatalities, 1,300 occurred on the island of Nias, with at least 200 additional deaths in the Banyak Islands and 100 more in Simeulue. These islands were devastated, with the majority of homes damaged or destroyed and entire villages razed. An additional 22 people were killed in mainland Sumatra. A tsunami was also generated, although it only reached up to 4.2 m ft high and caused moderate damage in the epicentral area. Tectonic setting The island of Sumatra lies on the convergent plate boundary between the Indo-Australian plate and the Eurasian plate. The convergence between these plates is highly oblique near Sumatra, with the displacement being accommodated by near pure dip-slip faulting along the subduction zone, known as the Sunda megathrust, and near pure strike-slip faulting along the Great Sumatran fault. The major slip events on the subduction zone interface are typically of megathrust type. Historically, great or giant megathrust earthquakes have been recorded in 1797, 1833, 1861, 2004, 2005 and 2007, most of them being associated with devastating tsunamis. Smaller (but still large) megathrust events have also occurred in the small gaps between the areas that slip during the larger events, in 1935, 1984, 2000, 2002 and 2004.Natawidjaja D. H.

Its epicenter was located on the island of Bangkaru, part of the Banyak Islands. It struck 30 km mi below the surface. The focal mechanism is consistent with megathrust faulting along a section of the Sunda megathrust. A rupture area of 420 km mi x 250 km mi was estimated, extending from Simeulue and Southwest Aceh Regency in the north, to the Batu Islands in the south, with a maximum slip of 9.248 m ft east of Simeulue. The observed source time function gives a 120-second duration for the earthquake, with the greatest phase of seismic moment release occurring about 40 seconds after initiation. Based on surface deformation, it was interpreted that up to 11 m ft of slip in layered elastic spaces under Sumatra.Hsu Ya-Ju Simons Mark Avouac Jean-Philippe Galetzka John Sieh Kerry Chlieh Mohamed Natawidjaja Danny Prawirodirdjo Linette Bock Yehuda 2006-06-30 Frictional Afterslip Following the 2005 Nias-Simeulue Earthquake, Sumatra https://www.science.org/doi/10.1126/science.1126960 Science 312 5782 1921–1926 10.1126/science.1126960 16809533 10356/94599 0036-8075 free 2024-09-20 2024-09-20 https://web.archive.org/web/20240920214827/https://www.science.org/doi/10.1126/science.1126960 live Because of the elastic environment, the converging oceanic and continental plates build energy and are then locked by friction. The continental plate is forced back, and then shortened, causing uplift. The converging plates exceed frictional forces (deformation), causing slip along the fault. After the March 28 earthquake, afterslips continued to occur for 11 months, exerting the energy equivalent to a single Mw 8.2 earthquake. The earthquake uplifted the entire 110 km mi stretch of Nias's western coastline by 2 m ft, expanding beaches and exposing coral reefs; up to 6 m ft of uplift was observed in the town of Lahewa on Nias's northwestern coast. It also caused Simeulue to rise by 2 m ft and the Banyak Islands to sink by 1 m ft.Indonesia: 28 March earthquake - Situation report #9 https://reliefweb.int/report/indonesia/indonesia-28-march-earthquake-situation-report-9 SurfAid ReliefWeb 2 April 2005 27 June 2026 Proof of uplift was recorded using cGPS stations, highest level of survival for coral, and coseismic slips.http://www.geology.wisc.edu/~chuck/Classes/Mtn_and_Plates/eq_cycle.html#:~:text=Co-seismic+slip+refers+to,exhibited+for+inter-seismic+motion Earthquakes geology.wisc.edu 2024-10-17 2007-11-20 https://web.archive.org/web/20071120073651/http://www.geology.wisc.edu/~chuck/Classes/Mtn_and_Plates/eq_cycle.html#:~:text=Co-seismic+slip+refers+to,exhibited+for+inter-seismic+motion live Before the 2005 earthquake, there were already three cGPS sites set up.

These measurements were derived from continuous GPS stations, with one on Nias recording 2.9 m ft of slip, supplemented by coral micro-atoll data indicating peak uplifts up to 2.8 m ft in coastal areas. Satellite altimetry from Jason-1 also contributed to mapping offshore vertical deformation patterns consistent with this range, validating the tectonic response over the ruptured megathrust segment. Modeling of the fault slip distribution, based on joint inversions of seismic waveforms, GPS, and InSAR data, revealed two primary asperities; a larger patch beneath Nias with maximum slip of 11 m ft at depths of 15–25 km mi, and a smaller patch under Simeulue with peak slip of around 7–8 m ft. The rupture propagated bilaterally from the hypocenter near the Banyak Islands, with overall slip decreasing toward the Sunda megathrust due to the inhibiting effect of accretionary prism sediments. This distribution accounted for the observed surface deformation, with the high-slip zones directly correlating to the elevated coastal uplifts.16809533 2006Sci...312.1921H 5782 10.1126/science.1126960 1921–1926 Science 30 June 2006 Frictional Afterslip Following the 2005 Nias-Simeulue Earthquake, Sumatra 312 https://web.gps.caltech.edu/~simons/publications/pdfs/Hsu_2006.pdf Ya-Ju Hsu Mark Simons Jean-Philippe Avouac Avouac John Galetzka Kerry Sieh Mohamed Chlieh Danny Natawidjaja Linette Prawirodirdjo Yehuda Bock In the twenty-four hours immediately after the event, there were eight major aftershocks, measuring between w 5.5 and 6.0.ISC-GEM Catalogue – Introduction http://www.isc.ac.uk/iscgem/index.php 2024-10-17 International Seismological Centre 2023-03-27 https://web.archive.org/web/20230327150736/http://www.isc.ac.uk/iscgem/index.php live By the end of 2005, there were 1,587 aftershocks exceeding w 4.0, including 140 events measuring w 5.0–5.9 and 13 exceeding w 6.0;USGS earthquake catalog United States Geological Survey https://earthquake.usgs.gov/earthquakes/map/?extent=0.0381,94.30664&extent=3.77072,100.98633&range=search&timeZone=utc&search=%7B%22name%22:%22Search%20Results%22,%22params%22:%7B%22endtime%22:%222005-12-31T16:09:36.530Z%22,%22latitude%22:2.085,%22longitude%22:97.108,%22maxradiuskm%22:250,%22minmagnitude%22:4,%22starttime%22:%222005-03-07T16:09:36.530Z%22%7D%7D the largest aftershock measured w 6.9, striking on 19 May 2005 with an epicenter close to that of the mainshock's.M 6.9 - 89 km WSW of Singkil, Indonesia 2005 usp000dr4t Despite the epicenter's proximity to that of the 2004 Indian Ocean earthquake, it ruptured a separate segment of the Sunda megathrust and was most likely triggered by stress changes associated with that earlier event.https://earthquake.usgs.gov/earthquakes/eqarchives/poster/2005/20050328.php Poster of the Northern Sumatra Earthquake of 28 March 2005 – Magnitude 8.7 United States Geological Survey 22 July 2010 26 June 2011 https://web.archive.org/web/20110514113830/http://earthquake.usgs.gov/earthquakes/eqarchives/poster/2005/20050328.php 2011-05-14 dead On Nias, the Modified Mercalli intensity was IX–X (Violent-Extreme) along the island's western coastline,Uplift and Damage from the MW8.7 Nias Earthquake of 28 March 2005 Dick Beetham Bill Sinclair Building resilience i-Rec 14 https://www.irbnet.de/daten/iconda/CIB11504.pdf 2 July 2026 VIII (Severe) in Gunungsitoli and VII (Very Strong) in Teluk Dalam.

MMI VI (Strong) shaking was recorded in Banda Aceh, while Medan, Padang and Palembang recorded an intensity of MMI V (Moderate). MMI IV (Light) shaking was felt in Bangkok, Thailand and the west coast of Malaysia, while in Singapore and the Maldives, the MMI was III (Weak). Tremors were also felt in Sri Lanka and the Andaman and Nicobar Islands, India. Tsunami Due to the earthquake's similar size to the 2004 Indian Ocean earthquake, many people feared a destructive ocean-wide tsunami similar to that of an event. Evacuations were carried out in coastal regions of Thailand, Malaysia, and Sri Lanka. The 2005 earthquake, however, produced a relatively small tsunami. A 3 m ft on tsunami caused moderate damage to the port and airport facilities on Simeulue, with a maximum runup of 4.2 m ft on at the village of Busung, and a 4 m ft on high tsunami was recorded at Nias and a 3.5 m ft surge struck the Banyak Islands. Run-ups of 4 m ft were also reported in coastal areas of northwestern Sumatra, with 2.3 m ft high waves striking Singkil and a 1 m ft wave observed at Meulaboh. Much smaller waves, most detectable only in tide gauge recording systems, were recorded across the Indian Ocean; for example, a 25 cm in wave was recorded at Colombo, Sri Lanka, while a 40 cm ft high surge struck the island of Hanimaadhoo in the Maldives. Seiches were also observed on ponds in West Bengal, India. Tsunami warnings were issued by the Pacific Tsunami Warning Center, operated by the US National Oceanic and Atmospheric Administration (NOAA), and by the government of Thailand. There were initial concerns that a major tsunami could be generated, particularly travelling south from the event's hypocenter.
