Η περιοχή του κόλπου του San Francisco είναι μια πολύ σεισμογενής περιοχή.Η σεισμικότητα οφείλεται στις τεκτονικές πλάκες (πλάκα του Ειρηνικού Ωκεανού και η πλάκα της Βόρειας Αμερικής) που κινούνται η μία σε σχέση με την άλλη. Τα όρια αυτών των πλακών ή η αλληλεπίδρασή τους εκφράζεται από τα ρήγματα της περιοχής, όπως το ρήγμα του Αγίου Ανδρέα και το ρήγμα του Hayward, τα οποία είναι ενεργά.Η ενεργός τεκτονική της περιοχής έχει σαν απότέλεσμα την εντυπωσιακή μορφολογία της περιοχής του κόλπου του San Francisco. Σειρά ισχυρών σεισμών έχουν πλήξει την περιοχή με βάση στοιχεία παλαιοσεισμολογίας κατά τους ιστορικούς χρόνους. Με βάση τα δεδομένα αυτά και την αρχή του ομοιομορφισμού εκτιμάται ότι παρόμοιου μεγέθους σεισμοί θα πλήξουν την περιοχή και στο άμεσο μέλλον. Οι προβλέψεις των επιστημόνων συγκλίνουν στο συμπέρασμα ότι στα επόμενα χρόνια, οι άνθρωποι θα ξαναδοκιμαστούν από τη σεισμική δράση στην περιοχή του San Francisco. Η ερευνητική δραστηριότητα των επιστημόνων στοχεύει στο να μετριασθούν οι επιπτώσεις αυτές οι οποίες είναι πολυποίκιλες και απαριθμούνται στη συνέχεια. Οι καταστροφές από τους σεισμούς διαχωρίζονται σε πρωτογενείς και δευτερογενείς. Στις δευτερογενείς που είναι και οι πιο καταστροφικές για το δομημένο περιβάλλον συγκαταλέγονται οι αστοχίες του δικτύου ύδρευσης, οι καταρρεύσεις ή οι βλάβες των σπιτιών και η υποβάθμιση στην ποιότητα των αποθεμάτων του πόσιμου νερού της μητροπολιτικής περιοχής. Επίσης οι σεισμοί προκαλούν τσουνάμι, ρευστοποιήσεις εδάφους, πυρκαγιές, θανάτους ανθρώπων, αλλά και υλικές ζημιές σε όλες τις κατασκευές του ανθρώπου. / The region of the Gulf of San Francisco is a very activity region. Seismicity is owed in the tectonic plates (plate of Pacific Ocean and the plate of Northern America) that they are moved the one concerning the other. The limits of these plates or the interaction to them it is expressed by the faults of region, as the fault of San Andreas and the fault of Hayward, which are active. The active tectonics of region have as result the impressive morphology of San Francisco bay region. Many earthquakes have affected the region. scientists appreciate that similar size earthquakes will also affect the region in the direct future. The inquiring activity of scientists aims in are moderated this repercussions. Τhe destructions by the earthquakes are separated in primary and secondary. In secondary that are also most devastating are included damages of water supply, collapse or the damage of houses and the devalorisation in the quality of reserves of potable water of metropolitan region. Also the earthquakes cause tsoynamis, liquidations of ground, fires, deaths of persons but also material damage in all the human manufactures.

O objetivo foi argumentar em torno das conseqüências da evolução conceitual observada sobre as políticas públicas de corte social, tendo em vista o planejamento e a avaliação da situação de segurança alimentar e nutricional. A análise realizada mostrou que o conceito de segurança alimentar e nutricional evoluiu de uma dimensão unicamente agrícola para uma dimensão de bem-estar humano, ganhando identidade com o Direito humano à alimentação. Resulta disto que a segurança alimentar e nutricional é atualmente um fenômeno complexo, atribuível a um conjunto de fatores. Desta forma, para alcançar êxito, as políticas públicas voltadas à eliminação do problema e também as estratégia para avaliá-las devem enfrentar as causas, articulando e fazendo convergir esforços de vários setores como agricultura, nutrição, saúde, bem-estar social, educação, economia, emprego, renda , entre outros. / Salvador

Spot cores from Phase 1 drilling of the main borehole at the San Andreas Fault Observatory at Depth (SAFOD) were mapped to characterize the mesoscale structure and infer paleostress at depth. Cores were oriented by comparing mapped structures with image logs of the borehole. The upper core (1476-1484 m measured depth, MD) is a medium-grained, weakly foliated, hornblende-biotite granodiorite containing leucocratic phenocrysts and lenses. Principal structures are sub-vertical veins, shallow dipping shears, and natural fractures of unknown kinematics. The features are compatible with horizontal extension and right-lateral, normal, oblique-slip on faults striking approximately parallel to the SAF. The lower core (3055.6-3067.2 m MD) has massivebedded, pebble conglomerates and coarse to fine grained arkosic sandstones grade into siltstones. Principal structure features are conjugate shears and two minor faults. The fracture fabric is consistent with strike-slip faulting and a maximum principal compressive paleostress at ~80° to the SAF plane. This paleostress is essentially parallel to the current in situ stress measured in the main borehole and to paleostresses inferred from fracture fabrics in exhumed faults of the San Andreas system to the south. The similarity between the current state of stress and paleostress states supports the suggestion that the maximum principal compressive stress direction is, on average, at high angles to the SAF and that the fault has been weak over geologic time.

The San Fernando Channel System is a superbly exposed submarine channel system of late Cretaceous age located on the Pacific coast of Baja California, Mexico.  High-resolution mapping and extensive system-wide correlation panels coupled with detailed sedimentology studies and interpretation of high-resolution photomosaics have shown that the system comprises a distinct hierarchy of stratigraphy components.  Extensive outcrops have allowed a detailed submarine channel model to be proposed which describes architecture and facies spanning outcrop to seismic scales. Channel complex sets are the largest mappable component within the system and are bounded by basal system-wide erosion surfaces.  Each set shows a consistent stratigraphic evolution comprising 3 distinct stages each characterised by distinct channel complexes. Channel complexes in Stage 1 are predominantly coarse-grained, highly amalgamated and confined within an extensive composite erosion surface. Stage 2 is dominated by channel complexes which are finer-grained, less amalgamated and laterally flanked by internal levee deposits. Stage 3 relates to the shutdown and gradual abandonment of the system and is dominated by fine-grained turbidites and well developed condensed intervals. The stratigraphic variation observed within the channel system is linked to sea-level fluctuations.  However, throughout the system, local contemporaneous faulting is shown to have a high degree of control on the location of sedimentation and commonly overrides the <i>normal </i>sea-level influenced depositional evolution.  Local faulting is also shown to profoundly affect both the local channel-fill type and the stacking patterns of architectural elements and channel complexes.  Stacking patterns of individual channel complexes are generally more predictable in Stage 2 than in Stage 1 which is attributed to the variation in relative confinement of the individual channel complexes.
