劳登消防员挖掘地下区域，扑救近10英亩火灾

现在

周一的红外扫描在约10英亩的火灾区域下方发现了残余燃烧。消防人员处理了更多热点，但尚无经核实的后续解除警报消息。

林地火灾何时才算真正扑灭——是烟雾消失时，还是火场下方的地面停止燃烧时？在新罕布什尔州劳登，一次无人机巡查发现了其中的区别：在消防人员以为周末的火灾已完全扑灭后，地下仍有两处热点在阴燃。⁠2⁠3

11月2日星期一，消防人员使用配备红外设备的无人机搜索过火区域，寻找热源。WMUR报道说，扫描发现了两处地下热点，消防人员周一扑灭了其他热点，并将持续监测一周。报道并未分别确认无人机发现的每一处热点都已熄灭。截至11月4日，尚无经核实的后续巡查宣布整个现场已完全冷却。⁠2

在11月2日的播报中，我们报道了消防局长托马斯·布朗谢特周日晚间的评估：当时看不到烟，据信这场近10英亩的火灾已完全扑灭，并计划使用热感无人机进行检查。现在，这项检查已经完成。检查结果取代了此前关于所有燃烧都已结束的判断——并非因为有新的火灾报告，而是因为表面看似平静之下仍有热源。⁠3⁠2

2周一发现的地下热点 2
约10英亩估计被烧毁的林地和灌木丛面积 12
0部门通报中报告的伤者人数 1

受影响地块位于贝里路、兰奇路和老沙克路附近。《康科德箴言报》11月2日的报道援引劳登消防局的通报称，无人受伤，也没有建筑物受损。报道还说，消防人员周一与新罕布什尔州森林保护局的护林员一同返回，检查是否还有可能复燃的热点。这次联合行动并不能证明是哪家机构操作了无人机。⁠1

烧毁面积仍为估算值。WMUR的后续报道称，周末火灾烧毁面积至少为10英亩；《康科德箴言报》则称约为10英亩。这些报道更新了此前“近10英亩”的说法，但不能证明火场边界后来扩大。报道所说的进展是受影响区域内仍有残余燃烧，而不是火势再次蔓延。⁠1⁠2⁠3

地表之下的扑救工作

地下发现的情况与消防人员从一开始遇到的困难相符。消防人员于10月31日星期六晚间首次赶到，工作至周日凌晨约1:30，随后于当天上午晚些时候返回。布朗谢特描述说，火势缓慢蔓延，火焰约有两英尺高，燃烧还延伸到地下。⁠3

该区域部分地块几年前曾进行过伐木作业。伐木残料、枯树桩和树根留下了燃烧物，消防人员无法仅从地面上方将其处理。他们挖开地下区域，并用专用工具切断树根和树木残料。可见的火焰只是扑救工作的一部分。⁠3

据《康科德箴言报》报道，消防局通报称，消防人员控制住火势后于周日下午撤离。到周日晚上，布朗谢特认为火灾已完全扑灭。这是先后作出的评估，并不相互矛盾：控制火势蔓延与确认每一处隐蔽热点都已冷却，是不同的阶段。周一的扫描说明了为何第二阶段仍然重要。⁠1⁠3⁠2

这并未解释最初的起火原因。布朗谢特说，火灾始于一片沼泽地，他认为这很不寻常，但消防人员无法确定实际起火源。发现地下热源回答的是燃烧持续在何处，并不能回答是什么引发了火灾。⁠3

人员调配和干燥地面加大了扑救难度

后续报道还更精确地说明了集结消防人员所需的时间。布朗谢特告诉WMUR：“人员调配是个问题。我们花了大约四个小时才凑齐45名消防员参与扑火。”这指的是集结这支队伍所需的时间，并非消防员迟到四小时。⁠2

这个数字更新了此前略少于40名消防员的说法；当时布朗谢特说，节假日和周末给人员调动带来了困难。多个消防部门和州林业工作人员提供了人员和设备；康科德和贝尔蒙特的消防员则负责应对劳登的其他在办警情。现有证据描述的是这起事件中的调动困难，并非经测算的全部门人员空缺率，也不是对部门预算的结论。⁠1⁠3

天气让扑救工作更加困难。布朗谢特在后续报道中说：“天气非常干燥。地面里一点水分都没有。”WMUR描述的应对条件包括风速为20到30 mph。此前的报道给出的风速范围是15到25 mph，但信息不足，无法确定这两个范围是否对应同一观测时段。不能将其视为风速已确认上升，也不能视为11月4日的天气情况。⁠2⁠3

《康科德箴言报》11月2日的报道将火灾置于一段持续干旱期内：新罕布什尔州大部分地区近两周没有明显降雨，且此前14个月的降水量远低于平均水平。落叶成为干燥的燃料，而光秃的树枝让更多阳光照到地面材料上，使其变干。⁠1

11月2日的报道指出，当时全州野火风险等级均为高，并预报至少未来几天没有降水。这些是应对火灾期间的风险等级和天气预报，并非最新天气信息。⁠1

布朗谢特给出的防火建议十分直接：“秋季清理时，无论你生什么篝火或烧什么灌木，都一定要确保火完全冷却。”他敦促居民多浇水、翻动灰烬，并谨慎检查是否仍有余热。他的警告并不意味着已有结论认定此次火灾由户外用火引起。⁠2

劳登的经历让两者的区别变得具体。看不到烟是有用的观察结果，却不能证明火已完全熄灭。原定的检查发现，确实还有燃烧需要处理。剩下的问题是，后续检查是否确认地面已完全冷却；现有后续报道尚未证实这一点。⁠2⁠3

播出原貌
  1. A drone found two underground hot spots in a fire crews had believed was out.
  2. Firefighters put out more hot spots and planned to monitor the burned ground through the week. On November 2, we reported that crews believed the fire was out Sunday evening, with a drone check still planned. Whether the ground is now completely cold remains unresolved.
  3. The fire burned woods and brush near Berry, Range and Old Shaker Roads in Loudon, New Hampshire. Firefighters returned Monday with rangers from the state's Forest Protection Bureau to search for remaining heat that could allow the fire to reignite.
  4. Officials estimated that at least 10 acres burned over the weekend. Another estimate put the area at around 10 acres. Those estimates update the nearly 10 acres described earlier. The new discovery was residual burning inside the affected area, with no renewed spread reported.
  5. Firefighters used an infrared-equipped drone to search for heat Monday, November 2. The scan found two hot spots smoldering underground. Crews worked to extinguish leftover burning, even after the surface had appeared quiet the previous evening.
  6. Crews had brought the blaze under control Sunday afternoon and left the scene. By Sunday evening, Chief Thomas Blanchette saw no visible smoke and believed it was completely out. Monday's heat search showed that burning had continued beneath the surface.
  7. Our November 2 broadcast left the drone inspection as the next step. That inspection has now happened. It found underground fire, and firefighters put out additional hot spots Monday. The absence of visible smoke Sunday hadn't meant every burning root was cold.
  8. Firefighters had already spent hours digging for this fire. They first responded Saturday evening, October 31, worked into the early hours of Sunday, and returned later that morning. Flames reached about two feet high, while the fire crept slowly through material on and beneath the ground.
  9. The affected ground included an area logged a couple of years earlier. Logging debris, dead stumps and roots gave crews difficult material to reach. Firefighters dug underground and used specialized tools to cut through roots and burning tree debris.
  10. The fire began in a marshy area, which Blanchette described as unusual. Crews couldn't determine what ignited it. Finding heat underground explains why firefighters needed to keep working there, but it doesn't explain the original ignition.
  11. Loudon Fire Chief Thomas Blanchette said staffing was an issue. He said assembling 45 firefighters took about four hours. That measures the time needed to gather that force. Crews had already begun responding Saturday evening.
  12. Blanchette's updated total is 45, compared with the earlier figure of just shy of 40. He had said the holiday and weekend complicated mobilization. Several departments and state forestry personnel supplied people and equipment. Concord and Belmont firefighters covered Loudon's other active calls while crews fought the woods fire.
  13. The Loudon Fire Department said nobody was injured and no buildings were damaged. Its November 2 announcement also described staffing and weather as challenges. Those findings add the injury and damage information that wasn't available when we previously covered the fire.
  14. Dry ground made the work harder. Blanchette said there was no moisture in the ground. The newer response description put winds at 20 to 30 miles an hour. Earlier estimates were 15 to 25, with no clear indication that they covered the same observation period.
  15. By November 2, most of New Hampshire had gone close to two weeks without significant rain. Precipitation was well below average over the previous 14 months. Fallen leaves supplied dry fuel, and bare branches let more sunlight reach and dry the ground.
  16. The state's wildfire-risk rating was high across New Hampshire, with high risk also described across much of northern New England. The November 2 outlook expected no precipitation for at least several days. Those were the conditions and forecast accompanying the response.
  17. Blanchette urged residents to make campfires and fall-cleanup brush fires completely cold. He advised adding plenty of water, stirring the remains and checking cautiously for heat. His earlier warning also covered smoking materials and wood stoves during dry conditions.
  18. Crews planned to keep monitoring the burned area through the week. As of November 4, it's still unclear whether both drone-detected hot spots were fully extinguished or whether a later inspection found the entire site cold.
