基拉韦厄火山山顶现新裂缝 夏威夷火山国家公园实施安全关闭
据 Maui Now 10 月 7 日报道，基拉韦厄火山山顶的不确定性促使夏威夷火山国家公园实施安全关闭。9 月 30 日至 10 月 1 日在基拉韦厄破火山口底部形成的新裂缝，经 10 月 6 日热成像仪测量温度约 140 华氏度，地面冒着蒸汽、温度偏高，显示地下活动仍在持续。
据美国地质调查局夏威夷火山观测站介绍，9 月下旬山顶下方的浅层岩浆侵入导致地面变形与地震群，包括 9 月 30 日一次 3.4 级地震引发的小规模落石。虽然没有发现与近期活动相关的岩浆气体迹象，但不稳定的地面与难以快速疏散的路线，促使公园管理方关闭了 Halemaumau 步道与拜伦岩架步道的部分路段——约 1.3 英里的徒步路线。
基拉韦厄火山警报级别维持在“观察”（WATCH），航空颜色代码为橙色。当前的间歇性喷发周期始于 2024 年 12 月 23 日，多次出现熔岩喷泉；最近一次喷发于 2026 年 8 月 25 日结束。
公园官员敦促游客远离关闭区域与悬崖边缘——崖壁可能毫无预警地坍塌。火山观测站正对山顶进行全天候监测。

Uncertainty at Kilauea Summit Prompts Safety Closures at Hawaii Volcanoes National Park
Uncertainty at the summit of Kilauea prompted safety closures at Hawaii Volcanoes National Park, Maui Now reported on October 7. New cracks that formed on the Kilauea caldera floor between September 30 and October 1 were measured by thermal camera at about 140 degrees on October 6, with steaming, warm ground indicating continued underground activity.
According to the U.S. Geological Survey's Hawaiian Volcano Observatory, a shallow magma intrusion beneath the summit in late September caused ground deformation and earthquake swarms, including a magnitude-3.4 earthquake on September 30 that triggered small rockfalls. While there was no sign of magmatic gas associated with the recent activity, the unstable ground and difficult evacuation routes led park officials to close the Halemaumau Trail and part of the Byron Ledge Trail — about 1.3 miles of hiking routes.
Kilauea's volcano alert level remains at WATCH, with the aviation color code at ORANGE. The current intermittent eruptive cycle began December 23, 2024, producing repeated episodes of lava fountaining; the most recent episode ended August 25, 2026.
Park officials urged visitors to stay out of closed areas and away from cliff edges, which can collapse without warning. The observatory continues to monitor the summit around the clock.
