经过八年的平静，费尔南迪纳火山在2017年9月4日和2018年6月16日经历了两次短暂的喷发。火山爆发的特点是在火山活动开始前几个小时就开始出现非常短暂的动荡。另一方面，Sierra Negra火山（伊萨贝拉岛）在经历了近一年的持续动荡之后，于2018年6月26日开始了新的喷发期，其特点是地震事件的规模和数量增加，自2005年最后一次喷发以来上升了5米以上。Sierra Negra和Fernandina火山位于偏远地区，进入那里极其复杂。因此，卫星图像补充了地球物理研究所（IG-EPN）的远程观测连续监测数据，并允许快速反应绘图，以确定受熔岩流影响的地区。最后，本报告的目的是鼓励其他科学家调查这些喷发期间记录的喷发前和喷发期的行为。
After eight years of quiescence, Fernandina volcano experienced two short-lived eruptions, on 4 September 2017 and 16 June 2018. The eruptions were characterized by very short periods of unrest that started a few hours before the initiation of the eruptive activity. On the other hand, Sierra Negra volcano (Isabela Island) began a new eruptive period on 26 June 2018, after almost one year of persistent unrest characterized by an increase in the magnitude and number of seismic events and more than 5 meters of uplift since its last eruption in 2005. The Sierra Negra and Fernandina eruptions were located in remote zones where access is extremely complex. Thus, satellite images complement the continuous monitoring data of the Instituto Geofisico (IG-EPN) with remote observations and allow rapid response mapping in order to identify the areas affected by the lava flows. Finally, the aim of this Report is to encourage other scientists to investigate the behaviors of both pre-eruptive and eruptive periods registered during these eruptions.
