| 摘 要： | 老黑山是五大连池火山群中最年轻的火山.通过对老黑山火山锥体结构及其形态分析指出,老黑山火山并非单锥,而是由先、后不同时期形成的两个锥体叠加组成的复合锥,表明它有两次喷发活动.通过对新发掘出的史料的分析,进一步指出,老黑山火山的第一次喷发时间为1720(不是1719年)-1721年,第二次可能为1776年.两次喷发活动的确认为研究老黑山火山喷发历史、喷发过程、喷发危险性评价和灾害预测等提供了新依据.

| Abstract: | Laoheishan Volcano is the youngest in Wudalianchi volcanic group. From a field observation and systematic analysis of the volcano, it is concluded that Laoheishan volcanic cone is not a single but a complex cone which is formed by eruptions during the two periods. It was discovered that two eruption were not same in character.The newly explored historical materials show that the first eruption occured during 1720 (not 1719)-1721 and the second maybe in 1776. The confirmation of two-stage eruptions is helpful to learn the history and process of Laoheishan Volcano eruption and the assessment and mitigation of volcanic hazard in the future. |
