Publicación Cambios en la dinámica litoral y nivel del mar durante el Holoceno en el Sur de Iberia y Canarias Orientales(Sociedad Geológica de España, 1996) Zazo Cardeña, Caridad; Dabrio, Cristino José; Goy Goy, José Luis; Bardají Azcárate, Teresa; Ghaleb, B.; Lario Gómez, JavierThe interaction between global factors tglobal" glacio-eustatic sea-leve/ rise) and regional factors (tectonic trend, oceanographic factor) is analyzed in different areas of the lberian and Canary lsland littora/. Sea-leve/ changes and climatic variations are stated for the Mediterranean and Atlantic littora/s, with different tidal ranges and tectonic trends. Different stages can be envisaged in the coastal evolution of a/most ali the analyzed areas from the beginning of Holocene (10.000 BP): at ca. 7.000 BP (Flandrian maximum) with a change from open estuaries to aggradational processes (Cádiz Gulf, subsiding area), basal peat (Valencia Gulf, subsiding area) and development of microcliffs (Mediterranean uplifting areas). From 7,000 to 2,700 BP a first progradation phase with development of spit bars took place in the mediterranean uplifting areas, whilst in the atlantic subsiding one starts the aggradation processes in the formerly open estuaries, an a/so from ca.4,000 BP development of spit-bar system. A second progradation phase ofthe spit bars systems occurs between 2,400 and 500 BP both in Almería and Cádiz Gulf, where a change from aggradation to progradation takes place in the estuary environments, and with a change in the direction of /ongshore drift (Mediterranean) and prevailing winds (both areas) at ca.2,400 BP. At ca. 1,200 BP a sudden paleogeographic change took place in estuary environments. From 500 BP up to now a marked increase of coastal progradation in ali littorals is observed. Climatic interpretations /ed to corre/ate anticyclonic conditions (as it happened during Little Ice Ages) with the growing of spit bar systems and progradation, while low pressure conditions (as during Medieval Warm Period) coincides with no progradation. In the Canary lslands, the development of storm ridges at ca. 3,500 BP can be corre/ated with an intensification of trade winds.Publicación Holocene incised-valley fills and coastal evolution in the Gulf of Cádiz (Southern Spain)(INQUA, International Union For Quaternary Research, 1998) Dabrio, Cristino José; Zazo Cardeña, Caridad; Goy Goy, José Luis; Sierro, F. J.; Borja, Francisco; González Delgado, José Ángel; Flores Villarejo, José Abel; Lario Gómez, JavierPublicación Los estudios científicos como herramienta para la conservación y gestión del Monumento Natural Cueva de Castañar (Extremadura)(Universidad de Oviedo, 2006) Muñoz Barco, P.; Alonso Zarza, Ana María; Sánchez Moral, Sergio; Martínez Flores, E.; Cuezva Robleño, Soledad; Gil Peña, Inmaculada; Martín Pérez, Ángel; Lario Gómez, JavierLa Cueva de Castañar, la cavidad con mayor abundancia de espeleotemas de aragonito de España, fue declarada Monumento Natural en el año 1997. Además de estos espeleotemas hay que resaltar la presencia de carbonatos magnésicos. Por ello, la Cueva de Castañar debe considerarse como un laboratorio natural. La cueva presenta un microclima estable y un bajo intercambio energético con el exterior. La oscilación térmica anual de la temperatura del aire es inferior a 0,1°C. Un sistema tan estable es muy frágil ante cualquier perturbación microambiental. Por ello, la entrada de visitantes debe ser mínima y muy controlada. Los resultados de los estudios están permitiendo establecer la estrategia de conservación del Monumento Natural.Publicación Presence of boulders associated with an extreme wave event in the western Mediterranean (Cape Cope, Murcia, Spain): possible evidence of a tsunami(Springer Nature, 2023-03-20) Spencer, Chris; Bardají Azcárate, Teresa; Lario Gómez, JavierLa región de Murcia, en el sureste de la Península Ibérica, registra una actividad tectónica moderada, registrándose terremotos de hasta 6,2-6,9 Mw. Aún con una actividad sísmica de esta magnitud no existen registros geológicos ni instrumentales de tsunamis que hayan afectado a la zona. La presencia en Cabo Cope, Murcia, de un cordón litoral de bloques imbricados de tamaño métrico (compuestos por rocas del Pleistoceno superior) que alcanzan una altura de hasta 4 m sobre el nivel del mar, indica que en la zona se ha producido un evento de oleaje extremo durante el Holoceno. Mediante el estudio de las condiciones de oleaje generadas durante grandes tormentas en esta zona, se infiere que este cordón litoral de bloques parece haber sido causado por oleaje extremo asociado a un evento sísmico, como un tsunami.Publicación Sea level and climate changes in the Cabo De Gata Lagoon (Almeria) during the last 6500 YR BP(INQUA, International Union For Quaternary Research, 1998) Goy Goy, José Luis; Zazo Cardeña, Caridad; Dabrio, Cristino José; Baena Preysler, Javier; Harvey, A. M.; Silva, Pablo Gabriel; González, F.; Lario Gómez, JavierThe Holocene evolution of the lagoon of Cabo de Gata in the geodynamic framework of the south-eastem lberian Península is presented for the first time. The work is based on detail geomorphological mapping of the Quaternary deposits, and radiocarbon measurements of samples collected in the spit barrier systems. The genesis of the Cabo de Gata and Roquetas lagoons is connected to the joint action of three factors. ( l ) Neotectonics, that controlled the occurrence of lowlands. (2) The general glacio-eustatic, Holocene transgression, that brought the sea level to elevations 1.5-2 m above its present values and, eventually, flooded the lowlands during the Flandrian maximum ca. 6500 yr BP. (3) The climate (humidity/aridity) that influenced the sediment supply to the coast and also the small fluctuations of sea level after the Flandrian maximum. Four spit-barrier units have been distinguished. Deposition of the two older ones (H1 and H2 ) took place between ca. 6500 and ca. 2500 yr BP under longshore drift towards the NW. Both units enclosed a lagoon that ·is placed to the NE of its present position. The more recent units (H3 and H4) close the present lagoon and were deposited between ca. 2300 and present under longshore drift to the SE. A more hum id period has been identified during the Gap separating units H1 and H2 (ca. 4400- 4200 yr BP) when most holocene alluvial fans were deposited. Aridity increased after ca. 2500 yr BP when aeolianPublicación Paleoseismology, Quaternary slip-rate and heat flow of the Benis Fault (SE of Spain)(Istituto Nazionale di Geofisica e Vulcanologia, 2015) Pérez López, Raúl; Martín Velázquez, S.; López Gutiérrez, J.; Silva, Pablo Gabriel; Rodríguez Pascua, Miguel Ángel ; Giner Robles, Jorge Luis; Lario Gómez, JavierWe have carried out a paleoseismic analysis of the Benis Fault, located at the southeast part of Spain. We have estimated the last earthquake size-magnitude and time, from evidence of celling collapse and displaced broken carbonate blocks (M6 and 65 ± 18 ka BP). Our analysis suggests that the tectonic slip-rate of the Benis Fault is lesser than 0.01 mm/yr. Additionally we have measured the deep thermal profile of the Benis Cave (-350 m of vertical development, Cieza, SE of Spain), from single rock point temperature measurements in different field campaigns and for a period of 2 years. The temperature increases with depth, being in consequence a reverse thermal profile in comparison with normal gradients in deep caves. Furthermore, we have estimated the Vertical Geothermal Gradient with a value of 1.85ºC/100 m for the deepest zone (-150-290 m). Finally, we have calculated the heat flux of 0,46 mWm2.Publicación Improving the coastal record of tsunamis in the ESI-07 scale: Tsunami Environmental Effects Scale (TEE-16 scale)(Universidad Politécnica de Barcelona, 2016-06) Bardají Azcárate, Teresa; Silva, Pablo G.; Zazo Cardeña, Caridad; Goy Goy, José Luis; Lario Gómez, JavierThis paper discusses possibilities to improve the Environmental Seismic Intensity Scale (ESI-07 scale), a scale based on the effects of earthquakes in the environment. This scale comprises twelve intensity degrees and considers primary and secondary effects, one of them the occurrence of tsunamis. Terminology and physical tsunami parameters corresponding to different intensity levels are often misleading and confusing. The present work proposes: i) a revised and updated catalogue of environmental and geological effects of tsunamis, gathering all the available information on Tsunami Environmental Effects (TEEs) produced by recent earthquake-tsunamis; ii) a specific intensity scale (TEE-16) for the effects of tsunamis in the natural environment at coastal areas. The proposed scale could be used in future tsunami events and, in historic and paleo-tsunami studies. The new TEE- 16 scale incorporates the size specific parameters already considered in the ESI-07 scale, such as wave height, run-up and inland extension of inundation, and a comprehensive and more accurate terminology that covers all the different intensity levels identifiable in the geological record (intensities VI-XII). The TEE-16 scale integrates the description and quantification of the potential sedimentary and erosional features (beach scours, transported boulders and classical tsunamites) derived from different tsunami events at diverse coastal environments (e.g. beaches, estuaries, rocky cliffs,). This new approach represents an innovative advance in relation to the tsunami descriptions provided by the ESI-07 scale, and allows the full application of the proposed scale in paleoseismological studies. The analysis of the revised and updated tsunami environmental damage suggests that local intensities recorded in coastal areas do not correlate well with the TEE-16 intensity (normally higher), but shows a good correlation with the earthquake magnitude (Mw). Tsunamis generated by earthquakes can then be considered efficient processes in the direct transference of the “energy” released by offshore seismogenic sources to the nearest coastal areas, even over distances of hundreds of kilometres (>200km). This scale, as the previous ones, is independent of the earthquake type (i.e. style of faulting) and only focuses on the environmental effects triggered by tsunamis of seismic origin.Publicación Variaciones del nivel del mar: Estadios isotópicos 7, 5 y 1 en las costas peninsulares (S y SE) e insulares españolas(AEQUA, 1994) Zazo Cardeña, Caridad; Goy Goy, José Luis; Hillaire Marcel, Claude; Dabrio, Cristino José; Hoyos Gómez, Manuel; Bardají Azcárate, Teresa; Somoza, L.; Silva, Pablo Gabriel; Lario Gómez, JavierPublicación Holocene changing coastlines in the Guadalete estuary (Bay of Cádiz, Southern Spain)(SISTEMAS RIAS, 1995) Dabrio, Cristino José; Goy Goy, José Luis; Zazo Cardeña, Caridad; Lario Gómez, JavierPublicación Intercambios de C02 suelo/cavidad en un sistema kárstico somero (Cueva de Altamira, Cantabria)(Sociedad Geológica de España. Universidad de Salamanca, 2004) Cuezva Robleño, Soledad; Sánchez Moral, Sergio; Cañaveras, Juan Carlos; Soler, V.; Lario Gómez, JavierThe monitoring system installed in Altamira Cave (Cantabria) is providing us a continuous record of microenvironmental data, for both cave atmosphere and air trapped in soil (air temperature,-atmospheric pressure, 222Rn, CO2 concentration). The karst system has a great importance in the global carbon cycle, not only far long-term cycles, but a/so far short-term ones. The C01 fluxes between the hypogea/ atmosphere and the externa/ soil air are controlled by differences of temperature and density of air, changes in atmospheric pressure and rainfa/1 regime. The local meteorologica/ conditions and the geometry of the cavity rule CO2 exchanges between cave atmosphere and air trapped in soi/. A temperature inversion (Tint > Text) and a great increase and stabilization in C01 levels takes place in Altamira Cave in autumn. Therefore, during this time the cave acts as a sink of atmospheric CO2•
