TL;DR: In this article, the authors investigate the mechanisms of formation of accretionary lapilli and demonstrate that growth is controlled by collision of liquid-coated particles due to differences in fall velocities, and binding as a result of surface tension forces and secondary mineral growth.

TL;DR: In this paper, the authors studied the sedimentation of ejecta from volcanic plumes as a function of distance from the source in the Fogo A plinian deposit, Sao Miguel, Azores.

TL;DR: The 2010 Eyjafjallajokull eruption lasted 39 days and had 4 different phases, of which the first and third (14-18 April and 5-6 May) were most intense as mentioned in this paper.

TL;DR: In this article, two-phase flow experiments have been carried out in vertical and inclined pipes with both single gas slugs and a continuously supplied gas phase, and the experimental pressure data support previous theoretical analyses of oscillatory sources in ascending slugs as the slugs approach the surface and burst.

TL;DR: In this paper, small silicate particles were produced in the laboratory during collisions between two samples cut from pumice clasts, and the particle charge magnitudes detected on these particles are similar to those previously measured on volcanic plumes (∼10−5 to 10−6 C kg−1).
