Geophysical constraints on the dynamics of spreading centres from rifting episodes on land
Most of the Earth's crust is created along 60,000 km of mid-ocean ridge system. Here,
tectonic plates spread apart and, in doing so, gradually build up stress. This stress is …

Volcanic activity and hazard in the East African Rift Zone
Over the past two decades, multidisciplinary studies have unearthed a rich history of
volcanic activity and unrest in the densely-populated East African Rift System, providing new …

Crustal and uppermost mantle shear wave velocity structure beneath the Middle East from surface wave tomography
We have constructed a 3-D shear wave velocity (Vs) model for the crust and uppermost
mantle beneath the Middle East using Rayleigh wave records obtained from ambient-noise …

Geodetic constraints on cratonic microplates and broad strain during rifting of thick Southern African lithosphere
Southern Africa is typically considered to belong to a single tectonic plate, Nubia, despite
active faulting along the southwestern branch of the East African Rift System. We analyze …

A complex mantle plume head below East Africa‐Arabia shaped by the lithosphere‐asthenosphere boundary topography
Hot plumes rising from Earth's deep mantle are thought to cause uplift, rifting and large
igneous province (LIP) emplacement. LIP volcanism in continents often spans tens of Ma …

Sulfur degassing at Erta Ale (Ethiopia) and Masaya (Nicaragua) volcanoes: Implications for degassing processes and oxygen fugacities of basaltic systems
We investigate the relationship between sulfur and oxygen fugacity at Erta Ale and Masaya
volcanoes. Oxygen fugacity was assessed utilizing Fe3+/∑ Fe and major element …

Simultaneous rift-scale inflation of a deep crustal sill network in Afar, East Africa
Decades of studies at divergent plate margins have revealed networks of magmatic sills at
the crust-mantle boundary. However, a lack of direct observations of deep magma motion …

[HTML][HTML] Tectonostratigraphic evolution and significance of the Afar Depression
Abstract The Afar Depression is a unique place on Earth where active rift processes can be
directly observed. It is believed to be close to continental breakup. The Afar hotspot has a …
