The objective of this study is to evaluate the petrophysical properties of four ignimbrites
employed as dimension stones. The natural stone under study is produced in Tenerife …

In volcanic terrains and in particular island regions, the aggregates come from the
mechanical crushing of lava rocks and pyroclastic deposits. This study offers an …

This paper analyses the engineering geological properties of the rocks and soils of the
Canary Islands based on data from field studies, laboratory tests and extensive databases …

New data on the geomechanical properties of the highly cohesive volcanic rocks of the
Canary Archipelago and their role in the flank stability on oceanic islands are provided in …

Basalts are a common lithology found beneath Lisbon and are the predominant rocks of the
Volcanic Complex of Lisbon (CVL)(72 Myr). These basalts exhibit variable texture and …

Extremely voluminous landslides with a long run-out (also known as megalandslides) on
oceanic volcanic islands are infrequent denudational processes on such islands. At the …

The geological and geomechanical characterizations of the volcanic rock mass succession
affected by the Güímar and La Orotava mega-landslides (Tenerife, Canary Island) are …

Slope movements are one of the natural hazards that most affect volcanic islands and often
cause alarm to society, as they produce considerable material losses, affect communications …

The geotechnical behaviour of volcanic materials has some particularities and differences
with respect to non volcanic materials that makes it a subject still under investigation. These …

Angra do Heroismo, the main town of Terceira Island in the Azores Archipelago, was hit in
1980 by a 7.2 magnitude earthquake that caused great destruction in the central part of the …
