“…Both islands are located on the Terceira spreading ridge but show evidence for a thicker lithosphere than beneath and close to the MAR; a thicker lithosphere beneath the Terceira Ridge compared to other spreading ridges was also previously predicted due to the ultra-slow spreading of this ridge that does not result in a thinning of the lithosphere (e.g. Vogt & Jung 2004).…”

“…Actually, in each of the previous three active examples, the expected RFF triple junction does not exist because the transform fault arm of the triple junction has evolved into a divergent boundary. In the case of the Azores triple junction, the Gloria Transform ends westwards in the oblique Terceira Rift (Vogt and Jung, 2004). At the Juan Fernandez triple junction, a spreading ridge developed at the western end of the Chile Transform, isolating the Juan Fernandez microplate from the Nazca, Pacific and Antarctic plates (Bird et al, 1998).…”

“…Lourenço et al (1998) postulated that a diffuse boundary simultaneously acts as an ultra-slow spreading centre and as a transfer zone between the MAR and the dextral Gloria Fault, because it accommodates the differential shear motion between the Eurasian and African plates. Vogt and Jung (2004) suggested that the Azores axis, with a length of 550 km, is the slowest spreading organized accreting plate boundary in the world, (seafloor spreading rates at the TR <1 cm/yr) with a typical mixture of faulting mechanisms that make difficult to understanding the dynamics of the ATJ. Nevertheless, the high level of seismicity along the MAR and the TR (Fig.…”

Resumen. La historia del archipiélago de Azores, desde el descubrimiento y colonización en la primera mitad del siglo XV hasta ahora, está marcada por los impactos sociales y económicos producidos por los terremotos, principalmente los de alta intensidad. La información compilada nos lleva a concluir que en este periodo 33 terremotos han afectado las islas de Azores con una intensidad igual o superior a VII, causando unas 6.300 muertes y la destrucción generalizada en algunas Islas del Archipiélago, principalmente en S. Miguel, Terceira, Graciosa, Faial, S. Jorge y Pico. La acomodación de los movimientos diferenciales que se producen debido al límite entre las placas eurasiática (EA), africana (AF) y norteamericana (NA) y también al volcanismo que ocurre en la región, son los principales responsables de la intensa actividad sísmica que ocurre en este archipiélago. Este trabajo revisa los temas científicos de los terremotos conocidos que han interferido severamente con la vida del pueblo azoreano a lo largo de su historia, a esos terremotos llamamos grandes terremotos. Palabras clave: Terremotos de Azores; Sismotectónica de Azores; Mecanismo focal de los terremotos de Azores.[en] Large earthquakes in the Azores Abstract. The history of the Azores archipelago, from its discovery and settlement in the first half of the 15th century through the present, is marked by the social and economic impacts produced by earthquakes, mainly the high-intensity ones. Information that has been compiled leads to the conclusion that in this period, 33 earthquakes with intensity equal to or greater than VII have affected the Azores, which caused approximately 6,300 deaths and widespread destruction on some islands of the archipelago, principally S. Miguel, Terceira, Graciosa, Faial, S. Jorge and Pico Islands. The accommodation of strain resulting from the dynamics of the Azores triple junction (ATJ) plate boundary and volcanism, which also occurs in the region, are the main factors responsible for the intense seismic activity in this archipelago. This work reviews the scientific issues of the known earthquakes that have severely interfered with the lives of the Azorean people throughout their history, which we call large earthquakes. Key words: Azores earthquakes; historical earthquakes; seismotectonics of Azores; focal mechanisms.
