Volcanoes are unquestionably one of the most spectacular and awe-inspiring features of the physical world. Our paradoxical fascination with them stems from their majestic beauty and powerful, sometimes deadly, destructiveness. Notwithstanding the tremendous advances in volcanology since ancient times, some ...

Another recent example concerns the Nyragongo or Nyamulagira volcanoes in the Republic of Congo, which affected a population of nearly one million people around the volcano, at approximately 15–30 km [20]. Therefore, in La Palma Island, the local population resided much closer to the ...
2Magmatic Volatiles - Which Gas Species Would Venus’ Volcanoes Emit Today and Which Can We Measure? 2.1Composition of Outgassed Magmatic Volatiles On Earth, chemical footprints of eruptions are often traced by measurements of SO2and other S-bearing gases (e.g., Oppenheimer et al.2011; Henley ...
Our method should be used to infer the probable duration of pyroclastic density currents in future events, with this contributing to hazard assessment of active volcanoes. Method The reconstruction of the impact parameters of PDCs is based on a flow mechanical model that starts with the assumption ...
Fig. 1: Volcanoes of the East African Rift System. a Distribution of volcanoes in the East African Rift, Afar Triangle and Arabian Peninsula from86. Symbol shape denotes whether deformation has been reported (square) or not (triangle) from6. Colours denotes whether historical eruptions have been...
However, the marine environmental impacts of volcanic eruptions on islands, such as La Palma, typically receive significantly less attention than the socio-economic, atmospheric, or land impacts. The volcanic ashes and the formation of the lava delta can alter the biochemical conditions of the surrou...
However, in a volcanic context, the supply of particles over time is certainly not constant but depends on eruption magnitude, intensity, duration and frequency. This variable sediment supply leads to complex remobilisation dynamics and deposits at volcanoes with pulsatory and long-lasting activity (...
Fig. 1: Comparison of volcanic (coloured) and total anthropogenic (grayscale) emission rates of selected metal pollutants. Volcanic sources shown are basaltic volcanoes with ash-poor emissions. Note that metals are typically measured during a single period of (often elevated) activity and so represe...
