Is It Awkward Getting A Brazalian Wax

THE FIRST TSUNAMI IN THE IBERIAN ATLANTIC COAST EFFECT COODLIGE

Geomorphology Research Group Environmental and Water Resources University of Huelva has been scientifically proven the existence of the first recorded historical tsunami on the coast Atlantic and took place between 218 BC and 210 BC This finding will allow a better understanding of these marine natural disasters and understand the history of civilizations.


Now we can try to figure out if the Romans occupied the southwestern Spain from its sole victory in the Punic Wars or the weakening of civilization settled and disappeared because of catastrophic events that of the tsunami, "lead researcher adventure Joaquín Rodríguez Vidal." We have signs geological (sediment) with characteristics similar to those of known tsunamis in Doñana and we have been able to date "resume.
Scientists have reached this conclusion from the study of sediments Doñana National Park, one of the places where they observed morphological and sedimentary evidence unrelated to the normal evolution a coast that has been under investigation for three doctoral theses.
The method of work has focused first on the reconstruction of the coastal landscape Huelva from aerial photographs (provided by the Andalusian Institute of Cartography Board Andalusia) and other photographs taken by satellites, Earth observation Landsat and Spot (and supplied by the National Geographic Institute ). With this data, "we saw how they position the barriers of cost, progress and setbacks," says the researcher.
The next step was to compare the data obtained foot field. To do this, scientists extracted sediment (sand and shells, mostly) different Doñana littoral barriers (marshes and ponds) and studied the composition of the sand, peat (remains of carbon-rich vegetation) and shells (residues arrivals the Huelva coast the tsunami Portuguese 1755).
With this information scientists warned in sediments from Huelva "similar to those of tsunamis, "says Joaquín Rodríguez, after comparison with the sediments studied today in the wake of tsunamis such as Indonesia (2004). These geologists have also been supported in studies conducted around the tsunami that took place in Lisbon in 1755 , a disaster that marked the birth of modern seismology as one of the first to be studied.
Now "continue studying the phenomenon to try to determine the potential for recurrence (repeat) future tsunamis in the Atlantic coast of the Gulf of Cadiz because this is one of the most conducive to suffer undersea earthquakes, which could have an impact on the coast of Huelva, Portuguese and Moroccan " Joaquin Rodriguez adds.
Therefore, one of the main working lines team of scholars is to "find new information about these natural disasters from the analysis of the last recurrence, with the difficulty that so far only had historical evidence of the tsunami in Portugal , 1755, "adds the researcher.
This research group is focused on studying dynamic processes in Earth's outer conflict with humans since the recent perspective and its relationship to human occupation of the territory, ie the action of storms, tsunamis and any other natural disaster.
