Attività solare e terremoti: la scienza ci crede, ma non del tutto

Dopo i terremoti in Venezuela e Colombia, torna la domanda sul ruolo del Sole nei sismi. L'ultimo studio INGV mostra una correlazione robusta con probabilità di errore inferiore a uno su centomila. I meccanismi fisici però non combaciano ancora con i numeri reali.

A dramatic split-scene scientific illustration showing the Sun in the upper half of the image, with visible solar proton flares and coronal activity radiating outward in deep oranges and yellows against the black of space, and in the lower half, a cross-section of tectonic fault lines deep within the Earth's crust, with visible stress fractures and crystalline quartz structures glowing faintly under mechanical pressure. Connecting the two halves, a subtle translucent arc representing the ionosphere curves across the middle, with faint electric field lines descending from the solar wind toward the lithosphere. In the foreground, a framed scientific graph on a researcher's desk shows two overlapping waveform curves slightly offset in time, illuminated by warm office light. The overall mood is contemplative and scientifically rigorous, rendered in a photorealistic editorial style with deep blues, warm ambers, and subtle greens, evoking the tension between statistical correlation and unproven causality.
