Appendix D: Tephra fall eruption source parameters and return period footprint contours

Eruption source parameters used for modelling tephra fall with Tephra2, and contours associated with the probability of exceeding up to 12 tephra thickness thresholds at return periods of 250, 500 and 1000 years.

Changes of sub-fossil chironomid assemblages associated with volcanic sediment deposition in an Andean lake (38°S), Chile Cambios en las asociaciones sub-fósiles de quironómidos, producto de la depositación de sedimentos volcánicos en un lago andino (38°S), Chile

Revista Chilena de Historia Natural, 2007
Chironomid assemblages and sedimentological parameters (grain size, organic content, mineralogy) of a short sediment core from Lake Galletué (38°41' S, 71°17' W) were analysed.

Sensitivity and clay mineralogy of weathered tephra-derived soil materials in the Tauranga region

, 2009
Soil sensitivity is defined as the ratio of peak to remoulded shear strength. Problem soil materials are those that show large strength losses on disruption, resulting in catastrophic failure, liquefaction and long run-out distances.

Morphology and formation of glassy volcanic ash from the August 12-15, 1991 eruption of Hudson Volcano, Chile

Latin American Journal of Sedimentology and Basin Analysis, 2005
The 1991 explosive eruption of Hudson volcano in Chile ejected about 2.7 km³ (DRE) of basalt and trachyandesite magma as tephra fall. A majority of the fallout occurred from an eruption during the period August 12-15, 1991, producing an extensive deposit
