Analysis reveals connections between steady-state volcanism and volcanic hazards, suggesting future research directions.

This research aims to evaluate steady-state volcanism across four oceanic hotspots and its implications for forecasting volcanic hazards.
Analyzed steady-state volcanic activity at Iceland, La Réunion, Hawai'i, and western Galápagos.
Investigated relationships between eruption rates and volcanic hazard assessments over decades.
Examined both increases and decreases in eruption rates to estimate expected volcanic volumes.
Steady-state activity observed with cycles of eruption rate changes over the decades.
Eruption rates often start low, then increase to balance with expected volumes.
Some instances showed higher eruptions than expected followed by lower rates proportional to excess magma.

Galetto et al. (2026) studied this question.
