1. The geometric spectrum of lava domes and spines: new perspectives from analysis of the Morphology of Viscous Extrusions(MoVE) global dataset

   02 Oct 2023 | Contributor(s):: Amy Myers, Claire Ellen Harnett, Eoghan Holohan, Thomas Walter, Michael Heap

   This dataset aims to collate data of the geometry of viscous lava extrusions. The dataset contains 323 entries of extrusion height, width, and magma composition listed for all entries.Further information (where available) includes spine length, a second diameter measurement, extrusion...

2. Global Archive of Dome Instabilities (GLADIS)

   out of 5 stars 

   13 Mar 2017 | Contributor(s):: Claire Ellen Harnett, Mark Thomas, Eliza S Calder, Susanna Kathryn Ebmeier, Alison Telford, William Murphy, Jurgen Neuberg

   Investigating the causal mechanisms of lava dome collapse is imperative in understanding the dynamic processes that occur during active lava dome growth. We present a worldwide database and provide an assessment of dome collapse across a diverse range of volcanoes in the Global Archive of Dome...

3. An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards

   out of 5 stars 

   28 Feb 2013 | Contributor(s):: Jessica L. Ball, Eliza S Calder, Marc Bernstein

   A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...

4. DomeHaz: Dome-forming eruptions database v3.0
