塔尔火山地震活动增加并发生喷发

菲律宾火山地震研究所周三报告称,位于八打雁省的塔尔火山在过去24小时内记录到10次火山地震和两次短时间的岩浆水蒸气喷发。

菲律宾火山地震研究所表示,该火山周二还经历了四次火山震动,持续时间在1至129分钟不等。这比前一天仅发生的个位数地震事件有所增加。

这两次岩浆水蒸气喷发分别发生在7月21日下午2点29分和晚上8点09分,持续时间分别为3分钟和4分钟。继7月12日、16日和17日发生喷发后,塔尔火山在7月已累计记录到五次此类喷发。

在监测期间,该火山共排放了129公吨二氧化硫,形成了高达2800米的浓厚羽流。目前未观察到火山烟雾或热流体上涌现象。塔尔火山仍处于1级警戒状态,表明处于低水平活跃期。
