LBOOP Solar Forcing and Avalanche-Style Triggering of Volcanic Kinetic-Energy Release

Reports of statistical associations between multi-decadal volcanic eruption frequency and
solar-activity proxies motivate a mechanistic question: if solar output is not only “less”
during low-sunspot intervals, but also measurably “out of phase” in the internal dynamo
waves that organize solar magnetism, can that altered forcing style change how the
Earth’s nonlinear geosystems release stored energy? Building on the double-dynamo /
principal-component picture of solar magnetic activity and phase interference used by
Zharkova and colleagues, and on published claims of correlation between eruption
frequencies and a solar background magnetic field (SBMF) proxy derived from Wilcox
Solar Observatory synoptic maps, we formalize “Less-But-Out-Of-Phase” (LBOOP)
forcing as a reduction in amplitude accompanied by a phase perturbation in one or more
solar-to-Earth coupling channels (irradiance and spectral irradiance, UVozone/stratospheric pathways, magnetospheric coupling, atmospheric electricity, etc.).
We then map LBOOP forcing into a threshold/avalanche framework for volcanic
triggering using standard nonlinear response tools (hazard models, Kramers escape, and
stochastic resonance) to show how small, phase-shifted periodic components can change
event timing even if total energy input is reduced. The framework is explicitly
hypothesis-level: it does not claim a proven causal link, but provides testable signatures
(phase-locked modulation, polarity dependence, lag structure, and nonlinear hazard
response) for future analysis.
