Tephrabase GIS and Tephrostratigraphy


This is the homepage of Tephrabase GIS and Tephrostratigraphy, an extension to Tephrabase where a set of academic-research oriented web-based GIS and profile tools can be found. These were developed by Dale Cameron (2011), who submitted an earlier version of these as his MSc Geographical Information Science dissertation at the University of Edinburgh in 2011.

The data currenty used in this extension are from Richard Streeter's 2012 PhD thesis (Streeter, 2012) and further details can be found in Streeter and Dugmore (2014). Other data in Tephrabase will be linked to this extension shortly.


These tools are still under development and will be available from this page. Tephrostratigraphic Profile Generator is the first on to go live.

The following tools are under development:

  • Sediment Accumulation Graph Generator
  • Tephra Layer Thickness Contour Plot & Point Shapefile Generator
  • Sediment Accumulation Contour Plot & Point Shapefile Generator
  • Paleo-Topography Contour Plot & Point Shapefile Generator
