Ceboruco volcano in western Mexico is catalogued as one of the five most hazardous volcanoes in the country (National Center for Disaster Prevention; CENAPRED); 32,927 people, distributed in several smaller cities, towns and villages, live within a 10 km radius from the volcano. Two permanent Global Navigation Satellite system (GNSS) stations were installed on the Ceboruco volcano in October 2018 to start monitoring surface deformation; we present the results from these two stations. The data was processed using a double-difference strategy to obtain velocity vectors in the ITRF2014 reference frame and 3D position time series. Daily position time series show periods of small-amplitude deflation and inflation of the volcanic edifice that may correspond to changes in its magmatic system. These results confirm that the Ceboruco volcano is currently active so that continuous monitoring is necessary to anticipate possible explosive activity.

墨西哥纳亚里特塞波鲁科火山表面变形

墨西哥西部的塞波鲁科火山被列为该国最危险的五座火山之一(国家防灾中心;CENAPRED);32,927 人分布在几个较小的城市、城镇和村庄,居住在距火山 10 公里范围内。2018 年 10 月,在 Ceboruco 火山上安装了两个永久性全球导航卫星系统 (GNSS) 站,开始监测地表变形;我们展示了这两个站的结果。使用双差策略处理数据以获得 ITRF2014 参考系和 3D 位置时间序列中的速度向量。每日位置时间序列显示了可能与其岩浆系统变化相对应的火山建筑物的小幅度通缩和膨胀时期。
