Common Tern SLIDE 1 Schematic illustrating the causes of Glacial Lake Outburst Floods (GLOFs).  The arrows indicate processes that form glacial hazards, from ice avalanches through to displacement waves from calving glacier tongues.  © Reynolds International Ltd, 2009.  All rights reserved.

SLIDE 2; Imja Tsho, Solukhumbu, Nepal, showing the main lake with the parent glaciers (right centre), lateral moraine ridges, and debris-covered ice as part of the terminal moraine complex.  The left-hand part of the terminal moraine complex is known to be ice free on the basis of geophysical investigations undertaken by Reynolds Geo-Sciences Ltd in 2002 and more recently by Japanese researchers.  The main mountain in the upper centre of the picture is the southern flank of Island Peak, just to the south of Mt Everest.  © Reynolds International Ltd, 2009.  All rights reserved.

  
SLIDE 3: The GLOF breach at Tsabai Tsho in Nepal.  An indication of scale can be gained from the two-storey houses that are just visible in the lower-right hand corner.  No-one was injured in this event.  © Reynolds International Ltd, 2009.  All rights reserved.
 
Common Tern SLIDE 4: Moraine and glacial lake complex at Safuna, Peru, after the massive landslide in April 2002.

SLIDE 5: (a) Ground Penetrating Radar section, and (b) the corresponding Electrical Resistivity Tomography section showing the resistive anomalies associated with massive glacier ice beneath a veneer of debris.  The lateral moraine is prominent at the right hand side of each graphic.  © Reynolds International Ltd, 2009.  All rights reserved.
