Abstract
Displacements and ground motions near volcanoes are one of the warning signs of
volcanic eruptions. One of the most important tools to detect such movements is the
technology provided by GNSS permanent stations network.
This paper studies the use of GNSS techniques for the determination of the spatial
and temporal displacements caused by 1803-02 underwater volcano that erupted on the
south coast of El Hierro island, in the Canary Islands, on 10 October 2011.
The paper also analyses and quantifies the ground displacements that occurred before
the eruption.
