Freundt H. The onset of the first Icod failures pre-dates the Abrigo eruption, which is only recorded in the last turbidite subunit. Interaction of mantle-derived magma with island crust? The terrestrial fauna is represented by rare gastropod shells and two bones of a giant endemic lizard Gallotia goliath. Personalised recommendations. Bull Volcanol —83 Google Scholar. The stratigraphy and composition of the deposits suggest at least two successive tsunamis, the second one reworking pumices from the DHF III pre-Abrigo and Abrigo explosive eruptions.

Tenerife ignimbrite does not look like ignimbrite from neighbor island Gran Canaria (pictures of Gran Canaria ignimbrite).

    Lithic occurrences within Quaternary phonolitic ignimbrites on Tenerife (Canary Islands) fall into three broad groupings: (1) massive ignimbrite with large.

    The late Pleistocene ( ± 19 ka) Abrigo Ignimbrite represents the last major explosive caldera-forming eruption on Tenerife.

    Note the difference between tsunami units A,B in terms of texture, mostly due to the abundance of pumices in unit B.

    The subunits are often separated by a thin layer of very fine material ash size.

    Geology 32— The monitoring and warning systems are unsuited to dealing with such events, but this study represents an important step towards an integrated volcano-tsunami risk evaluation. Numerical modelling Numerical simulations of debris avalanches and tsunamis were realized using Volcflow numerical package, which is able to dynamically model any kind of mass flow and related tsunami generation, propagation and inundation inland 1218 Author information Article notes Copyright and License information Disclaimer.

The large volume of 26 km 3 of erupted basalt compared with only 16 km 3 of the evolved P1 magmas, and the extremely high discharge rates inferred from model calculations are unusual for a basaltic eruption.
