A group of specialists from the University of Jaen conducted a research project on the Alhama de Murcia fault that caused the earthquakes in Lorca, whose epicenter is located seven miles east of the town.
The earthquakes that have rocked the town of Lorca “are related to the activity of the Alhama de Murcia fault,” said Juan Jimenez, a professor of geology at the University of Jaen (UJA), who heads one of two research projects This failure study group of Geological Processes and Resources of the Department of Geology of the UJA.
The fracture is in a great system of strike-slip faults active direction to northeast-southwest, stretching from Almeria to Alicante, the area known as the Trans-Alborán shear. This set is composed of the fault systems of Carboneras, Palomares and Alhama de Murcia, whose global movement system is similar to that developed by the San Andreas fault in California, though much smaller magnitude. The system causes the southeast segment of the Iberian Peninsula to move progressively toward the northeast.

Scientists at the Complutense University of Madrid show that metropolitan growth generates a significant loss and degradation of the heritage of the city, the result of partial and simplistic view we have of urban space.
What is the limit of today’s metropolises, where will you end Madrid?, How far it extends Barcelona? An obvious answer would be correct and over-to the municipal boundary. However, this may be a wrong answer, since the area of influence of large cities has well exceeded the political divisions drawn on maps. Currently it is not strange to live more than 50 miles from our jobs, paying our taxes in a town far away, but no stranger, which houses our office, retail or factory.
These questions are answered correctly or incorrectly with multiple answers come at the beginning of the subsequent reflections of the approach of any investigation, and in this case study on the changes generated by new urban interventions in historic cities developed by researchers Research Group “Tourism, Heritage and Development” of Universidad Complutense de Madrid.

The eruption of a volcano in Iceland disrupts the North-European air traffic. The ash cloud is expected to arrive in France Friday, April 16.
On the morning of April 15, several airports in Northern Europe (England, Ireland, Scotland, Sweden, Norway …) have halted many flights and air traffic over the North Sea is closed. In France, the airports in the north of the country were closed in 17 hours, while those of Orly, Roissy and Le Bourget will be 23 hours. The reason for these disturbances: the eruption of a volcano in Iceland, located under the glacier Eyjafjallajokull, 125 kilometers east of Reykjavik. The volcano in question, the Eyjafjoll (in French, the Mountain Island) is a stratovolcano about 700 000 years. The lava mixes with the melted glacier water and creates a plume of steam and ash that obscured the sky for much of northern Europe thanks to strong winds at high altitudes.

The extremely strong earthquake, which broke out in Chile on 27 February this year, was a complicated process of breaking, as scientists have discovered the GFZ (geosciences National Laboratory of Germany). Earthquakes of such magnitude covers practically the whole crust.
After a detailed analysis of seismic waves radiated by this earthquake during the first 134 seconds after the start of the break, investigators have concluded that only the region around the epicenter was active during the earliest moments. In the second minute of the active zone moved north to Santiago. Then, the region south of Concepcion was active for a short time. This pattern of break agrees well with the distribution of aftershocks over the next three days.
In 1960, the strongest earthquake suffered by humanity which reliable measurements are taken, had its origin in Valdivia, south of the affected region today.

European researchers have discovered a bacterium capable of producing oxygen. This element could thus have been present in the atmosphere long before the onset of photosynthesis.
It was not known in nature as three synthetic pathways of oxygen by living organisms: plants, algae and some bacteria during photosynthesis to produce oxygen from carbon dioxide and water, bacteria consume chlorates (eg ClO4–) And release oxygen, and finally, other bacteria also use free radicals, highly reactive oxidizing molecules from cell metabolism to produce oxygen. French researchers from the CEA, CNRS and Université d’Evry-Val d’Essonne, associated with Holland and German teams, just to find a fourth … that they may well be earlier. This complicates theories regarding the appearance of oxygen on Earth.

A simulation challenges our vision of the flows that agitate the liquid core of our planet, where Earth’s magnetic field arises.
Why the Earth Does a magnetic field? This is due to a dynamo in its liquid core, which consists mainly of iron and stirred by convection: indeed, in some configurations, the motion of a conducting fluid generate electric currents and magnetic field s ‘maintain mutually. It seeks to restore flows to the origin of the terrestrial dynamo, also called the geodynamo. Takehiro Miyagoshi, the Japanese Agency for Science and Technology Earth and Sea, and his colleagues have simulated using a “fluid dynamics” of low viscosity. They have thus revealed unexpected movements in the Earth’s core.

FireMap Project, which coordinates a research group at the University of Alcalá, has developed a software tool that facilitates integrated indices of fire risk from a variety of variables.
The fire has a role in the dynamics of terrestrial
ecosystems, appearing as one of the most decisive factors controlling the selection and adaptation of
species. It also has important implications for weather, as it is considered that biomass burning account for 40% of total CO2 emissions.
In addition to this important global impact, fires have regional implications that can be quite negative, especially when the
historical cycles of recurrence are modified, either by a sudden change in patterns of occupation of the territory (land abandonment in some areas , colonization in others), and by the indirect effects of global warming.

Researchers at the University of Granada have characterized the physical and mechanical properties of the crust in regionm grenadine, which presents an intense seismic activity. The work has linked the temperature of the crust with seismic activity, determining that in areas with higher temperatures there is a much lower probability of occurrence of earthquakes.
Africa and Europe are approaching a rate of 4mm per year, according to a direction of convergence towards the northwest. The position and
geometry of the boundary between the two plates is not known exactly, but is within the Gibraltar Arc, an area of intense seismic activity, not studied in depth.

The investigation was conducted by Francisco Sanchez Lavado. The work has three sequences optimal water treatment used in the cooking stage of the cork.
A thesis, University of Extremadura has addressed the removal of organic pollutants present in
wastewater generated by the
cork-producing industry. The work is by Francisco Sanchez Lavado, under the direction of professors in the Department of Chemical Engineering and Physical Chemistry, Jesus Beltran de Heredia, Teresa Gonzalez and Joaquin Dominguez Montero Vargas and with funding from regional and central administration.
