On 15 July 2003 an extremely large (7.6 Mw) strike‐slip earthquake initiated on or near the end of an active transform along the northern Central Indian Ridge. The event propagated away from the plate boundary along the typically inactive fracture zone, with a sense of slip that opposes the active transform slip direction. Seismically and hydroacoustically determined aftershock locations delineate a 210 ± 25 km long mainshock rupture. The seismic moment and rupture dimensions imply a stress…

Rupture characteristics of the 2003 Mw 7.6 mid‐Indian Ocean earthquake: Implications for seismic properties of young oceanic lithosphere
[1] Analysis of broadband seismograms from the 15 July 2003 large earthquake (M 7.6) in the central Indian Ocean reveals an unusual source process. The source duration of longer than a minute is more
A rare great earthquake on an oceanic fossil fracture zone
first motion solution found in this study and has a strike consistent with the fracture zone north of the bend. The southern fault plane, with strike 178 ◦ ,d ip 54 ◦ and rake 65 ◦ , has a strike
January 2006 seafloor‐spreading event at 9°50′N, East Pacific Rise: Ridge dike intrusion and transform fault interactions from regional hydroacoustic data
An array of autonomous underwater hydrophones is used to investigate regional seismicity associated with the 22 January 2006 seafloor‐spreading event on the northern East Pacific Rise near 9°50′N.
Segmentation of transform systems on the East Pacific Rise: Implications for earthquake processes at fast-slipping oceanic transform faults
Seven of the eight transform systems along the equatorial East Pacific Rise from 12° N to 15° S have undergone extension due to reorientation of plate motions and have been segmented into two or more
The relationship between seismicity and fault structure on the Discovery transform fault, East Pacific Rise
There is a global seismic moment deficit on mid‐ocean ridge transform faults, and the largest earthquakes on these faults do not rupture the full fault area. We explore the influence of physical
In-situ evidence for dextral active motion at the Arabia-India plate boundary
The Arabia-India plate boundary--also called theOwen fracture zone--is perhaps the least-known boundary among large tectonic plates1-6. Although it was identified early on as an example of a
The 2014 Mw 6.1 Bay of Bengal, Indian Ocean, Earthquake: A Possible Association with the 85° E Ridge
Oceanic intraplate earthquakes are known to occur either on active ridge-transform structures or by reactivation of their inactive counterparts, generally referred to as fossil ridges or transforms.
Marine Transform Faults and Fracture Zones: A Joint Perspective Integrating Seismicity, Fluid Flow and Life
Marine transform faults and associated fracture zones (MTFFZs) cover vast stretches of the ocean floor, where they play a key role in plate tectonics, accommodating the lateral movement of tectonic


The June 2000 Mw 7.9 earthquakes south of Sumatra: Deformation in the India–Australia Plate
[1] Two large (Mw 7.9) earthquakes occurred on 4 and 18 June 2000, south of Sumatra, beneath the Indian Ocean. Both earthquakes were predominantly left-lateral strike-slip on vertical N-S trending
Compound rupture of the great 1998 Antarctic plate earthquake
The March 25, 1998, Antarctic plate earthquake ruptured a portion of the Antarctic plate more than 200 km west of its boundary with the Australian plate. The Harvard centroid moment tensor solution
Mechanisms and depths of Atlantic transform earthquakes
We have studied 40 earthquakes on seven major transforms along the Mid-Atlantic Ridge. The majority show the expected transform-parallel strike-slip motion on steeply dipping fault planes. Some

Mechanism of earthquakes and nature of faulting on the mid‐oceanic ridges
The mechanisms of 17 earthquakes on the mid-oceanic ridges and their continental extensions were investigated using data from the World-Wide Standardized Seismograph Network of the U. S. Coast and
Earthquake slip on oceanic transform faults
It is found that earthquakes on the longer Romanche transform are systematically deeper than those on the neighbouring Chain transform, and these depths indicate that the maximum depth of brittle failure is at a temperature of ∼600 °C in oceanic lithosphere.
Intraplate seismicity and stresses in young oceanic lithosphere
We have conducted a systematic study of oceanic intraplate seismicity in the period 1964–1983 occurring in lithosphere younger than 35 million years. Focal mechanisms determined for 26 events using
A diffuse plate boundary model for Indian Ocean tectonics
It is suggested that motion along the virtually aseismic Owen fracture zone is negligible, so that Arabia and India are contained within a single Indo-Arabian plate divided from the Australian plate
