Mount Mazama and Crater Lake

The effect of pressurized magma chamber growth on melt migration and pre-caldera vent locations through time at Mount Mazama, Crater Lake, Oregon

Post-impact heating of a crater lake

Lacustrine sediments from the 24 km diameter Boltysh impact structure record the rapid formation of an intra-crater lake. Stable isotope compositions and organic maturity parameters from the lake sediments deposited post-impact show that they were heated by underlying impactites. This heating is attributed to the establishment of an impactgenerated hydrothermal system. Estimates of the duration...

Mt Ruapehu Crater Lake lahar hazard

This report documents the results of some additional computational hydraulic modelling of the historic 1953 lahar event down the Whangaehu River (which caused the Tangiwai disaster) and a hypothetical lahar event generated by a future collapse of the Mt Ruapehu Crater Lake outlet barrier. Based on the results of the additional work, the following conclusions were obtained regarding the lahar ev...

Speciation: Genomic Archipelagos in a Crater Lake

The opening stages of speciation remain poorly understood, especially from a genomic perspective. The genomes of newly discovered crater-lake cichlid fish shed light on the early phases of diversification and suggest that selection acts on multiple genomic regions.
