Reassessment of source parameters for three major earthquakes in the East African rift system from historical seismograms and bulletins
parameters major earthquakes
2015/9/30
Source parameters for three majo earthquakes in the East African rift are re-computed from historical seismograms and bulletins. The main shock and the largest foreshock of the August 25, 1906 earthqu...
Local stresses, dyke arrest and surface deformation in volcanic edificesand rift zones
dyke injection dyke arrest crustalstresses crustal layering surface deformation volcanic hazard
2015/9/15
Field studies indicate that nearly all eruptions in volcanic edifices and rift zones are supplied with magma through
fractures (dykes) that are opened by magmatic overpressure. While (inferred) dyke ...
Ez-response as a monitor of a Baikal rift fault electrical resistivity:3D modelling studies
Baikal rift zone electromagnetic monitoring transfer functions resistivity changes ofthe fault
2015/9/14
3D numerical studies have shown that the vertical voltage above the Baikal deep-water fault is detectable and that respective transfer functions, Ez-responses, are sensitive to the electrical resistiv...
Strain patterns along the Kaparelli–Asopos rift (central Greece) from campaign GPS data
GPS Strain Kaparelli Central Greece
2015/8/14
We present results from four GPS campaigns in the broader Kaparelli–Asopos area in central Greece. This area is undergoing extension as demonstrated by seismological, geodetic and geological data. The...
The South Atlantic rift basin evolved as a branch
of a large Jurassic–Cretaceous intraplate rift zone between
the African and South American plates during the final
break-up of western Gondwa...
Kinematics of the Asal Rift (Djibouti) Determined from the Deformation of Fieale Volcano
Kinematics Assal Rift Determined the Deformation of Female Volcano
2014/4/15
Because of its subaerial exposure the Asal rift segment provides an exceptional oppor-tunity to quantify the deformation field of an active rift and assess the contribution of tectonics and volcanism ...
New constraints on dike injection and fault slip during the 1975–1984 Krafla rift crisis, NE Iceland
New constraints dike injection fault slip Krafla rift crisis, NE Iceland
2014/4/15
Correlation of KH9 spy and SPOT5 satellite images, airphotos, digital elevation model differencing, electronic distance measurement, and leveling survey data is used to constrain the deformation resul...
Numerical modelling of quaternary deformation and post-rifting displacement in the Asal–Ghoubbet rift (Djibouti, Africa)
Asal–Ghoubbet rifting cycle rift zone fault creep dyke inflation magma injection
2014/4/15
Over the last three decades a host of information on rifting process relating to the geological and thermal structure, long-time scale deformation (Quaternary and Holocene) and rifting cycle displacem...
