The Aravalli–Delhi Fold Belt (ADFB) is one of three prominent ridges on the continental part Indian plate extending northward from central India and subducting beneath Himalayan arc. Though it seismogenic along its entire NE–SW structural trend, activity varies spatially with a noteworthy region higher seismicity in vicinity Delhi. We analyse historical modern instrumented seismicity. Using rec...

On September 5–7, 2018, a series of tremors were reported in Nigeria’s capital city, Abuja. These events followed growing list felt the stable intraplate region, where earthquakes are not expected. Here, we review available seismological, geological, and geodetic data that may shed light on origin these tremors. First, investigate seismic records for parent location orphan using technique suita...

Petrological data have been acquired on the natural trachytes from the Chaîne des Puys, French Massif Central, and on experimental products from phase equilibria in order to (i) constrain the storage conditions of the trachytic magmas that lead to explosive eruptions (dome destructions as block-and-ash flows or pumice-and-ash flows) and (ii) provide phase relationships and chemical compositions...

Intraplate compressional deformation in the Central Indian Basin is expressed as linear E-W trending topographic undulations and geoid anomlies with characteristic spacings of approximately 200 km. To elucidate the nature of this deformation, we develop models of an oceanic lithosphere in a state of horizontal compression. The lithosphere is treated as a viscous or plastic layer of uniform stre...
