The two largest earthquakes of the past 40 years ruptured a 1600-kilometer-long portion of the fault boundary between the Indo-Australian and southeastern Eurasian plates on 26 December 2004 [seismic moment magnitude (Mw) = 9.1 to 9.3] and 28 March 2005 (Mw = 8.6). The first event generated a tsunami that caused more than 283,000 deaths. Fault slip of up to 15 meters occurred near Banda Aceh, Sumatra, but to the north, along the Nicobar and Andaman Islands, rapid slip was much smaller. Tsunami… 
Rupture Process of the 2004 Sumatra-Andaman Earthquake
The 26 December 2004 Sumatra-Andaman earthquake initiated slowly, with small slip and a slow rupture speed for the first 40 to 60 seconds. Then the rupture expanded at a speed of about 2.5 kilometers
Review of the source characteristics of the Great Sumatra–Andaman Islands earthquake of 2004
The December 26, 2004 Sumatra–Andaman Island earthquake, which ruptured the Sunda Trench subduction zone, is one of the three largest earthquakes to occur since global monitoring began in the 1890s.
Plate-boundary deformation associated with the great Sumatra–Andaman earthquake
Estimates of the ground displacement associated with the Sumatra–Andaman earthquake are reported, using near-field Global Positioning System surveys in northwestern Sumatra combined with in situ and remote observations of the vertical motion of coral reefs, to show that the earthquake was generated by rupture of the Sunda subduction megathrust over a distance of >1,500 kilometres and a width of <150  Kilometres.
The Sumatra tsunami of 26 December 2004 as observed in the North Pacific and North Atlantic oceans
The Mw=9.3 megathrust earthquake of December 26, 2004 off the coast of Sumatra in the Indian Ocean generated a catastrophic tsunami that caused widespread damage in coastal areas and left more than
Tsunami 2004 preparedness from the perspective of the Penang community
It has been 10 years since the 2004 Sumatera-Andaman earthquake which was the largest earthquake in 40 years with a moment magnitude of Mw=9.2 with seismicity travelling 1600 km along the entire
Evidence of strain accumulation in the Andaman region for the giant 2004 Sumatra Andaman earthquake
Abstract We report results of Global Positioning System (GPS) and tide gauge data from the Andaman region that pertain to the period before the 26 December 2004 Sumatra–Andaman earthquake ( M w
Seismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake
The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1,200–1,300 km. The seismic moment, M0, determined with a finite source model, was
Slow slip below Port Blair, Andaman, during the great Sumatra‐Andaman earthquake of 26 December 2004
Although several studies suggest that a slow slip followed the seismic slip on the northern half of the 1300‐km long plate interface that ruptured during the great Sumatra‐Andaman earthquake, the


Rupture Process of the 2004 Sumatra-Andaman Earthquake
The 26 December 2004 Sumatra-Andaman earthquake initiated slowly, with small slip and a slow rupture speed for the first 40 to 60 seconds. Then the rupture expanded at a speed of about 2.5 kilometers
The June 23, 2001 Peru earthquake and the southern Peru subduction zone
The plate boundary between the South American and Nazca plate along the south‐central Peru coast has been the site of large destructive earthquakes for many centuries, including the June 23, 2001
The Size and Duration of the Sumatra-Andaman Earthquake from Far-Field Static Offsets
This work used static offsets at continuously operating GPS stations at distances of up to 4500 kilometers from the epicenter to model the earthquake and includes consideration of the Earth's shape and depth-varying rigidity.
Seismology: Energy radiation from the Sumatra earthquake
This analysis was able rapidly to define the extent of rupture, thereby aiding the assessment of seismic hazard in the immediate future.
Earth's Free Oscillations Excited by the 26 December 2004 Sumatra-Andaman Earthquake
Using more realistic rupture models on a steeper fault derived from seismic body and surface waves, free oscillation amplitudes are approximated with a seismic moment that corresponds to a moment magnitude of 9.15 and underpredict geodetic displacements that argue for slow fault motion beneath the Nicobar and Andaman islands.
The 1992 Nicaragua earthquake: a slow tsunami earthquake associated with subducted sediments
THE 1992 Nicaragua earthquake was a ‘tsunami earthquake‘; that is, it generated tsunamis1 disproportionately large for its surface-wave magnitude, Ms. The moment magnitude, Mw, determined from
Source spectra of great earthquakes: Teleseismic constraints on rupture process and strong motion
Short-period body waves recorded at teleseismic distances from great earthquakes provide information about source rupture processes and strong motions. First, we examine mostly WWSSN records of 19
Paleogeodetic records of seismic and aseismic subduction from central Sumatran microatolls, Indonesia
We utilize coral microatolls in western Sumatra to document vertical deformation associated with subduction. Microatolls are very sensitive to fluctuations in sea level and thus act as natural tide

Earthquakes exhibit diverse characteristics. Most shallow earthquakes are “brittle” in the sense that they excite seismic waves efficiently. However, some earthquakes are slow, as characterized by
Observational constraints on the fracture energy of subduction zone earthquakes
We relate seismologically observable parameters such as radiated energy, seismic moment, rupture area, and rupture speed to the dynamics of faulting. To achieve this objective, we computed the
