¿Volverá Shishaldin a 'NORMAL' (vuelta a la normalidad)?

Por qué: Extracted condition: USGS must record Shishaldin's Volcano Alert Level as 'NORMAL' at any time between 2026-10-19T00:00:00+00:00 and 2026-10-22T00:00:00+00:00. Supplied USGS data (retrieved 2026-10-22 08:41 UTC) lists Shishaldin as 'ADVISORY' with 'level unchanged since 2025-08-25 19:48:35 UTC (previous level: NORMAL)'. The last change to ADVISORY occurred on 2025-08-25, which is before the market window start, so the ADVISORY level held throughout the entire window. Therefore Shishaldin was not 'NORMAL' at any time during 2026-10-19 to 2026-10-22, so the market resolves NO. Observed value used: ADVISORY (unchanged since 2025-08-25 19:48:35 UTC) vs required 'NORMAL' -> mismatch.
