THE DAY IN CONTEXT

Daily briefing

Captured 2026-10-13 23:58:44 UTC. Changes describe our source records, not Earth’s overall safety.

How to read this ↗
  1. 01Largest earthquake magnitude among records captured today: M 6.8 - central Mid-Atlantic Ridge. Event time: 2026-10-13 12:23 UTC. ↗
  2. 02A source record changed after an earlier capture: Hurricane Simon ↗
  3. 03128 NWS alert series captured today across its US coverage area. These are selected Severe/Extreme messages, not a count of separate storms. ↗
  4. 04NOAA SWPC published/updated at 20:58 UTC: EXTENDED WARNING: Geomagnetic K-index of 4 expected ↗
  5. 05All monitored event feeds responded successfully at this capture. Their geographic and reporting limits still apply. ↗
Initial baseline
0
Newly tracked
77
Revised
85
Carried forward
141

Newly tracked means first seen by this journal after its source baseline. Revised takes precedence over other change labels. Carried forward means seen again today without a captured change, not necessarily an ongoing hazard. Source lookback windows include older records, so these counts differ from the dated ledger.

Series may overlap across agencies. A message’s expiry or disappearance does not establish that a hazard has ended. Histories open the latest captured source record.
