夏威夷夏威夷岛上的Kallauea火山火山活动的历史记录始于1790年的蒸汽岩浆爆炸。30年后，在1823年，由英国牧师威廉·埃利斯（William Ellis）组织的第一批非夏威夷游客到达了克基拉岛的顶峰。埃利斯的详细叙述包括在他访问前不久发生在克基拉岛西南裂谷带的火山爆发。由于缺乏其他来源的材料，1790年和1823年之间的火山爆发被在Kampallauea工作的地质学家忽略了，他们认为在这段时间里，山顶破火山口之外的火山活动几乎没有发生。仔细的地层观察结合放射性碳年代测定表明，在这些年里，西南裂谷带发生了一系列喷发，其中包括两次持续时间较长（数周至数月）的喷发。包括这些事件提供了一个更完整的历史记录（1790年后）的Kempllauea和更好地了解其喷发行为。
The historical record of volcanic activity at Kīlauea Volcano on the Island of Hawaiʻi begins with the phreatomagmatic blasts of 1790. Three decades later, in 1823, the first party of non-Hawaiian visitors, organized by the English Reverend William Ellis, reached Kīlauea’s summit. A detailed narrative by Ellis includes an account of an eruption in Kīlauea’s Southwest Rift Zone that occurred shortly before his visit. In the absence of other source materials, the interval between the eruptions of 1790 and 1823 has been overlooked by geologists working at Kīlauea, with the presumption that little if anything took place volcanically outside of the summit caldera during that time. Careful stratigraphic observations combined with radiocarbon dating demonstrate that during these years a set of Southwest Rift Zone eruptions took place, including two that were long-lasting (weeks to months). Inclusion of these events gives a more complete historical (post-1790) record for Kīlauea and a better understanding of its eruptive behavior.
