Auler1 & Tatiana A. R. Souza1 1 Instituto do Carste, Rua Aquiles Lobo 197, Belo Horizonte, 30150-160, Minas Gerais, Brazil, [email protected] Under Brazilian legislation, subsoil features, including caves and mineral deposits, belong to the union and can only be exploited according to strict laws. Detailed geological and biological studies should be performed in each cave in order to determine its significance level: Maximum, High, Medium or Low (Auler & Piló, 2015). No environmental impact is allowed in maximum significance caves and a buffer zone must be established, taking into consideration the preservation of cave dynamics, including hydrogeology, structural integrity, ecosystem conservation, etc. Although caves of high, medium and low significance can be subject to environmental impacts, buffer protection zones must also be applied until the approval of studies, a complex procedure that may take at least 1.5 years. Out of the many factors that have to be taken into consideration in establishing the protection buffer zone, cave integrity in relation to present or future blasting scenarios is among the most complex. Because these new laws came into application in 2008, it is extremely common for caves to be located in close proximity (or even inside) quarries, resulting in mining closure and considerable financial losses. Variations related to rock type (caves in iron-ore, limestone and quartzite), distinct fragility of various features in caves (speleothems, rock projections, etc) and structural and lithological changes on the terrain between the blasting site and the caves make calculations related to explosive amount and blast design difficult. There is no established Peak Particle Velocity (PPV) criteria for caves, and thus, adaptations from international standards related to very sensitive structures (e.g. historical building or monuments of special value or significance) have been adopted, resulting in PPV between 5 – 15 mm/sec. Cave monitoring for physical integrity in Brazil initially involves a detailed characterization of zones more susceptible to breakdown, sometimes including joint aperture measurements and modelling. A second step deals with high resolution photograph monitoring according to Moura et al. (2013). A cave fragility zoning is thus established, allowing for the determination of the cave areas more favourable to collapse. Regular visits and repeated photographs in the same sites enable the determination of even minute changes in the cave configuration. In parallel, seismograph monitoring allows for control of the blasting intensity and correlations to possible cave damage.

  • Repeated Occurrence of Surface-Sediment Remobilization
    Ikehara et al. Earth, Planets and Space (2020) 72:114 https://doi.org/10.1186/s40623-020-01241-y FULL PAPER Open Access Repeated occurrence of surface-sediment remobilization along the landward slope of the Japan Trench by great earthquakes Ken Ikehara1* , Kazuko Usami1,2 and Toshiya Kanamatsu3 Abstract Deep-sea turbidites have been utilized to understand the history of past large earthquakes. Surface-sediment remo- bilization is considered to be a mechanism for the initiation of earthquake-induced turbidity currents, based on the studies on the event deposits formed by recent great earthquakes, such as the 2011 Tohoku-oki earthquake, although submarine slope failure has been considered to be a major contributor. However, it is still unclear that the surface-sed- iment remobilization has actually occurred in past great earthquakes. We examined a sediment core recovered from the mid-slope terrace (MST) along the Japan Trench to fnd evidence of past earthquake-induced surface-sediment remobilization. Coupled radiocarbon dates for turbidite and hemipelagic muds in the core show small age diferences (less than a few 100 years) and suggest that initiation of turbidity currents caused by the earthquake-induced surface- sediment remobilization has occurred repeatedly during the last 2300 years. On the other hand, two turbidites among the examined 11 turbidites show relatively large age diferences (~ 5000 years) that indicate the occurrence of large sea-foor disturbances such as submarine slope failures. The sedimentological (i.e., of diatomaceous nature and high sedimentation rates) and tectonic (i.e., continuous subsidence and isolated small basins) settings of the MST sedimentary basins provide favorable conditions for the repeated initiation of turbidity currents and for deposition and preservation of fne-grained turbidites.

    Usami et al. Geosci. Lett. (2018) 5:11 https://doi.org/10.1186/s40562-018-0110-2 RESEARCH LETTER Open Access Supercycle in great earthquake recurrence along the Japan Trench over the last 4000 years Kazuko Usami1,5* , Ken Ikehara1, Toshiya Kanamatsu2 and Cecilia M. McHugh3,4 Abstract On the landward slope of the Japan Trench, the mid-slope terrace (MST) is located at a depth of 4000–6000 m. Two piston cores from the MST were analyzed to assess the applicability of the MST for turbidite paleoseismology and to fnd out reliable recurrence record of the great earthquakes along the Japan Trench. The cores have preserved records of ~ 12 seismo-turbidites (event deposits) during the last 4000 years. In the upper parts of the two cores, only the following earthquakes (magnitude M ~ 8 and larger) were clearly recorded: the 2011 Tohoku, the 1896 Sanriku, the 1454 Kyotoku, and the 869 Jogan earthquake. In the lower part of the cores, turbidites were deposited alternately in the northern and southern sites during the periods between concurrent depositional events occurring at intervals of 500–900 years. Considering the characteristics of the coring sites for their sensitivity to earthquake shaking, the con- current depositional events likely correspond to a supercycle that follows giant (M ~ 9) earthquakes along the Japan Trench. Preliminary estimations of peak ground acceleration for the historical earthquakes recorded as the turbidites imply that each rupture length of the 1454 and 869 earthquakes was over 200 km. The earthquakes related to the supercycle have occurred over at least the last 4000 years, and the cycle seems to have become slightly shorter in recent years.

On the other hand, the geodetically based slip rate tides and Halley’s comet, don’t follow a regular schedule, as shown by across the eastern California shear zone (ECSZ) in the Mojave Desert 1) the earliest multiple-event paleoseismological studies at Pallett Creek is close to twice the rate based on late Quaternary geology. Weldon on the San Andreas fault (Sieh, 1978), 2) trenching studies on the Wasatch et al.

The publications by means of which the IAEA establishes standards are issued in the IAEA Safety Standards Series. This series covers nuclear safety, radiation safety, transport safety and waste safety. The publication categories in the series are Safety Fundamentals, Safety Requirements and Safety Guides. Information on the IAEAs safety standards programme is available at the IAEA Internet site http://www-ns.iaea.org/standards/ The site provides the texts in English of published and draft safety standards. The texts of safety standards issued in Arabic, Chinese, French, Russian and Spanish, the IAEA Safety Glossary and a status report for safety standards under development are also available. For further information, please contact the IAEA at PO Box 100, 1400 Vienna, Austria. All users of IAEA safety standards are invited to inform the IAEA of experience in their use (e.g.
