Abstract Analysis of the pre-and post-eruption topography, together with observations of the
avalanche deposition sequence, yields a triggering mechanism for the 6 August 2012 …

This paper tries to characterize volcanic rocks through the development and application of
an empirical geomechanical system. Geotechnical information was collected from the …

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 …

The geotechnical behaviour of very weak pyroclastic rocks controls both the failure
mechanisms at the margins of rock mesas, where historic hill towns are often sited, as well …

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

The failure criterion of low-density volcanic rocks differs radically from that of conventional
rocks by manifesting collapse under isotropic stress. In this way, the shapes of the failure …

The present research focuses on the calculation of the bearing capacity of low-density
volcanic Pyroclasts. First, the theoretical basis that define an adequate failure criterion for …

The mechanical behavior of low-density volcanic materials is at the transition between hard
soils and weak rocks. These materials often show dangerous sudden failures, without …

Some relevant aspects related to the mechanical behavior of volcanic rocks are considered,
mainly based on laboratory tests performed on rocks from the Canary Islands. Ranges of …
