Understanding the magmatic plumbing system of rift volcanoes is essential when examining interplay between and tectonic forces. Recent seismicity, volcanic activity, magma emplacement, volatile release make Natron basin ideal location to study these processes in East African Rift System. Here, we present first high-resolution tomographic imaging Oldoinyo Lengai volcano surrounding systems using...

a r t i c l e i n f o The silicic dome complex of Santiaguito, Guatemala, has exhibited continuous extrusive activity for 90 years. Despite its longevity, remarkably little is known about the magmatic plumbing system beneath Santiaguito. Here, we use petrological analyses of lava samples to define this plumbing system, from storage in the lower to mid-crust through to extrusion onto the surface...

Excessive lead has been found in drinking water in Hong Kong in tests carried out in 2015. Investigations have identified that the problem in public rental housing estates was caused by the problematic solders used in the plumbing, and recommendations on enhancing the quality control system and strengthening the relevant water quality standards have been proposed. The cause for the same problem...
