Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Messages from the past: the petroglyphs of El Hierro Island, Canary Islands
Geology TodayAncient cultures have frequently made use of stone surfaces to carve and engrave symbols, letters and messages for others. These petroglyphs usually have a lasting character and are frequently preserved well beyond the survival of the culture that produced the petroglyphs.

Effect of interfacial properties on mechanical stability of ash deposit
Journal of Rock Mechanics and Geotechnical Engineering, 2016 The paper presents a study on the cohesion of volcanic ash particles using surface free energy determination and zeta potential analyses. This is a subject of great interest in physical volcanology, as many researches on volcanic particle aggregation are

Increasing Demand Covered by Renewable Energy in El Hierro Island
Sustainability, 2023 The power system of the El Hierro island comprises a wind farm, a pumped storage hydropower plant and a diesel power plant. Its operational history shows that the renewable energy participation in the energy mix is approximately 50%. In order to increase this participation, the installation of residential photovoltaic generation and battery storage has

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

Hydropower Plants Frequency Regulation Depending on Upper Reservoir Water Level
Energies, 2019 This paper presents a novel method of hydro power plant operation, based on the control of the injectors’ or wicked gates opening time as a function of the upper reservoir level. In this way, a faster power injection, depending on the current water
