A tank was ruptured in Orange County, triggering a chemical crisis that led to widespread evacuations. The situation has changed after five days, with officials reducing the evacuation zone to about 16,000 people, according to bluesky. However, bangkokpost reported that some 50,000 evacuated residents need to remain in place. Accounts differ on the current population affected by evacuation orders. The threat of a toxic chemical tank explosion is off the table, according to bangkokpost, while bluesky reported that the threat of a massive chemical explosion has been 'eliminated'.
