Earthquake swarms occur sporadically at divergent plate boundaries but their recurrence over multiple decades and relation to magmatic spreading activity remain poorly understood. Here we study more than 100 earthquake swarms over a 60-year period in

Our understanding of melt production during early continental breakup remains poorly constrained. Using the Afar triple junction as an example, Gallacher et al. generate a 3D velocity model suggesting that melt production is highest during early cont

SUMMARY The present-day tectonics of the southern Red Sea region is complicated by the presence of the overlapping Afar and southern Red Sea rifts as well as the uncertain kinematics and extent of the Danakil block in between. Here we combine up to 1

Compared with other manifestations of climate variability that may not be perceived within a human lifetime, abrupt environmental disturbances arising from volcanism can be directly experienced. Despite abundant Pleistocene calderas in the East Afric

The dramatic landscape of Eritrea is driven by large tectonic forces that are breaking apart the African continent. It lies at the northernmost extent of the East-Africa rift and due to these dynamic processes, volcanism and seismic activity are comm

The East African Rift System (EARS) has natural hazards – earthquakes, volcanic eruptions, and landslides along the faulted margins, and in response to ground shaking. Strong damaging earthquakes have been occurring in the region along the EARS thr

To date little is known about seismic hazard in Eritrea, despite its locationin a volcanically and tectonically active region, and the gathering pace of major infrastructure projects. In response, we report the findings of a comprehensive probabilist

We present a synthesis of diverse observations of the first recorded eruption of Nabro volcano, Eritrea, which began on 12 June 2011. While no monitoring of the volcano was in effect at the time, it has been possible to reconstruct the nature and evo

Mantle plumes and consequent plate extension have been invoked as the likely cause of East African Rift volcanism. However, the nature of mantle upwelling is debated, with proposed configurations ranging from a single broad plume connected to the la

The seismicity of the southern Red Sea is driven by the geological and geophysical processes taking place at and around the Afar Triple Junction, where the Red Sea, East African, and Gulf of Aden Rifts meet. From this plate tectonic node, the Nubian,
