Shishaldin voltará a 'NORMAL' (retorno ao normal)?

Por quê: Extracted condition: USGS must record Shishaldin's Volcano Alert Level = "NORMAL" at any time after 2026-09-09T00:00:00Z and before 2026-09-12T00:00:00Z. Target window: (2026-09-09 00:00:00 UTC, 2026-09-12 00:00:00 UTC). Observed data (USGS feed retrieved 2026-09-12 06:03 UTC): Shishaldin is listed as ADVISORY with "level unchanged since 2025-08-25 19:48:35 UTC (previous level: NORMAL)". The feed lists only elevated volcanoes (absence => NORMAL); Shishaldin is present and ADVISORY. Because the "level unchanged since" timestamp (2025-08-25 19:48:35 UTC) is before the market window start, the ADVISORY level was in effect throughout the entire window and there was no time during the window when the level was NORMAL. Therefore the market resolves NO.
