[1] Thermal infrared (TIR) data from the MASTER airborne imaging spectrometer were acquired over Mount St. Helens in Sept and Oct, 2004, before and after the onset of recent eruptive activity. Pre-eruption data showed no measurable increase in surface temperatures before the first phreatic eruption on Oct 1. MASTER data acquired during the initial eruptive episode on Oct 14 showed maximum tempe...

The BishopTuff is a giant silicic ignimbrite erupted at 0·76Ma in eastern California, USA. Five pumice clasts from the late-erupted Bishop Tuff (Aeolian Buttes) were studied in an effort to better understand the preand syn-eruptive history of the Bishop magma body and place constraints on the timescales of its existence. This study complements and expands on a previous study that focused on ear...

Fire eruption (also known as ‘blow-up’ or ‘flare-up’) is a very dangerous aspect of wildland fire behaviour. It poses a significant threat to the safety of wildland fire-fighters and complicates the broader problem of wildfire risk management in complex terrain. Despite the seriousness of eruptive fire events, operational wildland fire spread models generally do not account for the possibility ...
