In the 1926 eruption, phreatic explosions preceded magmatic eruptions of the main phase, which brought about the collapse of the NW sector of the preexisting central cone followed by hydrothermal surges and snow melting, resulting in lahars (Uesawa 2010).
In the case of the storm of 15 May , 1997 occurring around 1 58 UT, as shown in Fig. 8(a), the scaling exponent at the CLF observatory increases, and fluctuates around the value β(t) ≈ 2.5 during the 6 hours corresponding to the initial part of the main phase, which is identified with the SYM-H index.
Influenced by fifth-order base-level changes, four LMVs evolutionary stages are summarized in (a) to (d), and among which (b) to (d) are the main phases during which the LMVs developed.
The work was undertaken in two phases: a pilot phase in which two stools were processed, and a main phase in which a further 17 stools were processed.
According to the modern definition, a geomagnetic storm is characterized by a main phase during which the horizontal component of the Earth's low-latitude magnetic fields are significantly depressed over a time span of one to a few hours followed by its recovery, which may extend over several days (Rostoker et al. 1997).
The full redevelopment consists of seven main phases, some of which are planned to run concurrently.
The algorithm consists of two main phases, one in which it computes visibility information, i.e., visl(f) and visa(f) for each fragment f, and the other in which it computes Recurrences (1)–(3) in Lemma 4.1.
As was explained in the Characterization of Exogenous Attention to Nonemotional Stimuli and in the Temporal Characterization: Main Phases sections, in which the temporal dynamics of exogenous attention were described, this sensory enhancement occurs in parallel with at least part of the preattention/evaluation and reorienting processes and is visible from 90 ms to latencies beyond 500 ms.
The focus is predominantly on the construction and on the operational phases, which are listed in all their main elements.
