The second phase of activity began three million years ago, emplacing rhyolitic magma 150 m thick and 13 m long during a single event of activity.
This second phase of activity 2.7 ± 0.7 million years ago resulted in the creation of the Vulcan's Thumb, a craggy volcanic ridge on the southern flank of the Mount Cayley proper.
Then, the second phase of activity was again increased before reaching the plateau.
During the second phase of activities, we ensured usage of rubric was consistent across raters to determine inter-rater reliability.
In the first phase of activity, thermo-mechanical fatigue (TMF) tests were performed on plain uniaxial tensile specimens subject to service-like loading conditions characterized by low strain rates, thermal transients to 565 °C and long hold times at the peak temperature.
The fourth phase of activity began one million years ago when the Cordilleran Ice Sheet retreated from the upper flanks of the adjacent lava plateau, creating Mount Edziza proper which is the most northerly of the four central volcanoes.
Ice Peak, 2500 m high, which overlaps the northern flank of Armadillo Peak, began to form during Edziza's third phase of activity, starting 1,600,000 years ago when the regional Cordilleran Ice Sheet began retreating.
In the first phase of activity there was a strong response to contralateral stimuli, with no response or even weak suppression to ipsilateral (early period, contralateral > ipsilateral, P < 0.001 in anova with factors category × cue × hemifield).
Although the international collaborative has limited its efforts to four countries/regions in its first phase of activity, subsequent phases will be gradually enlarged to include additional countries, and assess the feasibility of using the same approach at a larger and more global level.
The first phase of activities involved expert review of the rubric and rating the importance of attributes covered in order to ensure that the rubric appropriately measures our targeted construct within the context of extant literature, and as a way of establishing construct validity of the rubric.
Scope of the second phase of the activity, which is currently running, is the validation of the developed material in simulated operative conditions, by demonstrative components testing in a PWT (plasma wind tunnel) facility.
