夏威夷标志性霍雷海拱坍塌入海

夏威夷大岛火山国家公园内的霍雷海拱于2024年9月23日至27日间坍塌入太平洋1。这座高90英尺的海拱已有约550年的历史，是该地区最著名的景观之一1。

美国国家公园管理处指出，该海拱所在的海岸线多年来一直显示不稳定迹象1。2018年基拉韦厄火山喷发及其引发的山顶坍塌加剧了周边悬崖的损伤1。公园管理部门早在2021年就曾警告称这座海拱最终将坍塌1。2020年1月，因发现裂缝和结构不稳定，公园关闭了原有的观景区，并开放了更安全的新观景点1。同年热带风暴曾导致岩石从海拱底部脱落1。这处位于链状火山口路末端的景点此前吸引了大量游客前来观光1。

Hawaii's renowned Hōlei Sea Arch, a 90-foot-tall natural landmark that formed approximately 550 years ago, collapsed into the Pacific Ocean between September 23 and 27, 2024 1. Located at the end of Chain of Craters Road in Hawaii Volcanoes National Park on the Big Island, the arch had long been a popular tourist attraction before its dramatic failure 1.

The U.S. National Park Service attributed the collapse to years of coastal instability in the region 1. The 2018 eruption of Kīlauea volcano and subsequent summit collapse intensified damage to the surrounding cliffs, accelerating the arch's deterioration 1. In January 2020, park officials identified significant cracks and structural concerns, prompting them to close the original viewing area and establish a safer alternative viewpoint 1. That same year, a tropical storm contributed further damage by dislodging rocks from the arch's base 1. The National Park Service had warned as early as 2021 that the arch would eventually collapse 1.
