Article
Full-text available
Tephra layers in lake sediment cores are regularly used for tephrostratigraphy as isochronous features for dating and recording eruption frequencies. However, their value for determining volcanic eruption size and style may be complicated by processes occurring in the lake that modify the thickness and grain size distributions of the deposit. To as...
Conference Paper
Full-text available
Pumice cones are found globally in peralkaline rhyolite centres, and are typical of post-caldera eruptions at volcanoes in the Main Ethiopian Rift, Pantelleria and Mayor Island. But what style of eruption produces them, and how concerned should we be if one takes place? There are no recorded observations of these eruptions, and due to their similar...

Aluto is a silicic volcano in central Ethiopia, flanked by two large population centers and home to an expanding geothermal power plant. Here we present data from two lake sediment cores sampled 12 and 25 km from the volcano, which record at least 24 distinct eruptions in the Holocene. Tephra layers from the two cores are correlated using a variety...
Article
The Main Ethiopian Rift (MER, ~7–9°N) is the type example of a magma-assisted continental rift. The rift axis is populated with regularly spaced silicic caldera complexes and central stratovolcanoes, interspersed with large fields of small mafic scoria cones. The recent (latest Pleistocene to Holocene) history of volcanism in the MER is poorly know...
