On the external forcing of global eruptive activity in the past 300 years
Le Mouël, J-L.; Gibert, D.; Courtillot, V.; Dumont, S.; de Bremond Ars, J.; Petrosino, S.; Zuddas F. Lopes, P.; Boulé, J-B.; Neves, MC; Custódio, S.The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between internal and external processes, with time scales spanning multiple orders of magnitude. We review periodicities that have been detected or correlated with volcanic eruptions/phenomena and interpreted as resulting from external forces....
Developing paleogeographic heritage concepts and ideas through the Upper Jurass...
Henriques, M. H.; Reis, R. Pena dos; Garcia, G. G.; João, P.; Marques, R. M.; Custódio, S.The Salgado and Consolação geosites are located on the Portuguese coast of the West Iberian Margin and represent two Upper Jurassic reference sections of the Amaral Formation interpreted as a barrier-lagoon depositional environment within a mixed carbonate platform context. Outcrops exposure and access conditions allow the detailed study of the succession, as well as its use as a geotourism target, and as a par...
PRISM3D: a 3-D reference seismic model for Iberia and adjacent areas
Arroucau, Pierre; Custódio, S.; Civiero, Chiara; Silveira, Graça; Dias, Nuno; Diaz, J.; Villasenor, A.; Bodin, ThomasWe present PRISM3D, a 3-D reference seismic model of P- and S-wave velocities for Iberia and adjacent areas. PRISM3D results from the combination of the most up-to-date earth models available for the region. It extends horizontally from 15 degrees W to 5 degrees E in longitude, 34 degrees N to 46 degrees N in latitude and vertically from 3.5 km above to 200 km below sea level, and is modelled on a regular grid ...

Classification of the dup 15q13.3 CNV: A National data collection
Sousa, A.; Serafim, S.; Santos, R.; Custódio, S.; Ávila, M.; Dupont, J.; Dias P, P.; Moldovan, O.; Melo, J.; Ferreira, S.; Pires, L.; Leão, M.; Sá, S.Introduction: The proximal region 15q11q14 is one of the most unstable regions in the human genome, with six recognizable break points (BP1-BP6). In 15q13.3 there is a recurrent small CNV (BP4-BP5) consisting of a 350-680 Kb duplication, encompassing the CHRNA7 gene, which encodes the alpha 7 subunit of the neuronal nicotinic acetylcholine receptor. Although microdeletions of CHRNA7 are known to cause intellect...
ShakeMap: Combinação de observações instrumentais e macrossísmicas
Marreiros, C.; Carvalho, Sara; Alves, P. M.; Custódio, S.; Carrilho, F.Since 2008, the Portuguese seismological service, has implemented the ShakeMap software package provided by U.S. Geological Survey (USGS), in order to obtain reliable maps of peak ground motion parameters and seismic intensities for mainland Portugal. These maps identify the area affected by the earthquake and estimate the severity of ground shaking, thus providing important information for emergency response p...
Project WILAS – West Iberia Lithosphere and Astenosphere Structure
Dias, Nuno; Carrilho, Fernando; Haberland, C.; Fonseca, J.; Custódio, S.; Caldeira, Bento; Villaseñor, AThe lithosphere of Iberia has been formed through a number of processes of continental collision and extension: in Lower Paleozoic, the collision of three tectonics blocks produced the Variscan Orogeny, the main event of formation of the lithosphere. The subsequent Mesozoic rifting and breakup of the Pangea had a profound effect on the continental crust of Iberia. Since the Miocene, the southern interaction bet...
C3G - A portuguese collaboration for geology, geodesy and geophysics
Caldeira, Bruno; Caldeira, R.; Carrilho, F.; Carvalho, J.; Custódio, S.; Dias, Nuno; Fernandes, R.; Moreira, M.; Seixas, T.; Silva, M.; Quental, L.Portugal joined the effort to create the EPOS infrastructure in 2008, and it became immediately apparent that a national network of Earth Sciences infrastructures was required to participate in the initiative. At that time, FCT was promoting the creation of a national infrastructure called RNG - Rede Nacional de Geofísica (National Geophysics Network). A memorandum of understanding had been agreed upon, and it ...

A História da Sismologia no Instituto Geofísico da Universidade de Coimbra
Narciso, J.; Custódio, S.; Batlló, J.; Lopes, F. C.; Martins, D.; Gomes, C.; Ribeiro, P.Comunicação apresentada ao VIII Congresso Nacional de Geologia, em Braga (9-16 de Julho 2010); O Instituto Geofísico da Universidade de Coimbra (IGUC) foi fundado em 1864 como observatório meteorológico. As observações sísmicas só terão sido iniciadas de forma regular 43 anos mais tarde, em 1907. Os registos sísmicos que o IGUC possui actualmente representam uma das maiores e melhor conservadas séries de regist...
