Evidence for motion between Nubia and Somalia along the Southwest Indian ridge

  title={Evidence for motion between Nubia and Somalia along the Southwest Indian ridge},
  author={Dezhi Chu and Richard G. Gordon},
The East African rift marks the northern boundary of the Nubian (West African) and Somalian (East African) plates, and has formed by horizontal stretching due to the separation of these plates. South of ∼20° S, any expression of deformation or seismicity due to the relative motion of these two distinct plates vanishes, although the boundary must continue until it intersects another plate boundary. The nearest such boundary is that of the Antarctic plate, marked by the Southwest Indian ridge… 
Location of the Nubia-Somalia boundary along the Southwest Indian Ridge
The northern boundary between the Nubian (West African) and Somalian (East African) plates is marked by the existence of the East African Rift, which is the locus of roughly east-west stretching due
Plate kinematic evidence for the existence of a distinct plate between the Nubian and Somalian plates along the Southwest Indian Ridge
[1] Previously, we estimated the angular velocity of the Nubian plate relative to the Somalian plate from an updated set of spreading rates and transform fault azimuths. We found that the
Earthquake hazard in Africa : perspectives on the Nubia-Somalia boundary : news and view
A wide plate boundary zone between the Nubia and Somalia plates extends through eastern and southern Africa, from the Red Sea-Gulf of Aden region to the mid-oceanic Southwest Indian Ridge. The
The angular velocity of Nubia relative to Somalia and the location of the Nubia—Somalia–Antarctica triple junction
SUMMARY An ew analysis of geologically current plate motion across the Southwest Indian ridge (SWIR) and of the current location of the Nubia‐Antarctica‐Somalia triple junction is presented.
Kinematics of the East African Rift from GPS and earthquake slip vector data
Abstract Although the East African Rift (EAR) System is often cited as the archetype for models of continental rifting and break-up, its present-day kinematics remains poorly constrained. We show
Motion of Nubia relative to Antarctica since 11 Ma: Implications for Nubia-Somalia, Pacific–North America, and India-Eurasia motion
Recent estimates of the rotation between Nubia and Somalia have resulted in disparate poles of rotation for the motion since 3.16 Ma (southwest of South Africa) compared with that since 11.03 Ma
Extension across the Indian–Arabian plate boundary:the Murray Ridge
SUMMARY Seismic reflection profiles from the Murray Ridge in the Gulf of Oman, northwest Indian Ocean, show a significant component of extension across the predominantly strike-slip Indian‐Arabian
Present‐day kinematics of the East African Rift
The East African Rift (EAR) is a type locale for investigating the processes that drive continental rifting and breakup. The current kinematics of this ~5000 km long divergent plate boundary between
The relative motion between Africa and Eurasia as derived from ITRF2000 and GPS data
Studies of intra‐ and inter‐plate deformation typically need a model describing the motions of the stable part of the tectonic plates for reference purposes. We have developed DEOS2k, a model for the


The Somalia plate and the East African Rift System: present-day kinematics
SUMMARY The motion of the Somalia plate relative to the Nubia (Africa), Arabia and Antarctica platcs is re-evaluated using a new inversion method based on a Monte Carlo technique and a least absolute
Intraplate deformation and closure of the Australia-Antarctica-Africa plate circuit
To determine the current motion between the Australian, Antarctic, and African plates, and to test whether this plate circuit obeys closure, all plate motion data available along the Southeast,
Earthquakes in the Davie Ridge‐Madagascar region and the southern Nubian‐Somalian plate boundary
The largest earthquake sequence (mb up to 6.4 and M0 up to 5 × 1018 Nm) to have struck eastern Africa within the past 60 years occurred in May and June of 1985 off the coast of the
Kinematic constraints on distributed lithospheric deformation in the equatorial Indian Ocean from present motion between the Australian and Indian Plates
From an expanded, accurate, and up-to-date data set comprising 110 spreading rates, 46 transform azimuths, and 151 earthquake slip vectors from the Indian Ocean and Gulf of Aden, we determine a new
The Motion and Boundary Between the Capricorn and Australian Plates
The motions between the Somalian, Antarctic, and Australian plates—the three plates believed to meet at the Rodrigues triple junction in the Indian Ocean—are inconsistent with the assumption that all
Present‐day plate motions
A data set comprising 110 spreading rates, 78 transform fault azimuths, and 142 earthquake slip vectors has been inverted to yield a new instantaneous plate motion model, designated Relative Motion 2
Current plate motions
SUMMARY We determine best-fitting Euler vectors, closure-fitting Euler vectors, and a new global model (NUVEL-1) describing the geologically current motion between 12 assumed-rigid plates by
Historical seismicity and implications for diffuse plate convergence in the northeast Indian Ocean
Large historical earthquakes provide constraints on the geographical extent and kinematics of the slow, diffuse plate boundary extending from the Central Indian Ridge to the Sumatra Trench. The fault
