Economist. ON MARCH 22nd, exactly one year after a series of suicide bombings killed 32 civilians in Brussels, a terrorist attacked central London.


The British-born man drove a car along the pavement across Westminster Bridge, killing at least two people and leaving around 40 injured. He then entered the grounds of Parliament, the heart of Britain’s democracy, and fatally stabbed an unarmed policeman before being shot dead. This “marauding” method of terror attack—using a vehicle to mow people down in a crowded area—was similar to atrocities carried out by Islamists last year in France and Germany.

It was the deadliest terrorist attack London has suffered since the Tube and bus bombings of 2005. Many other western European countries have suffered similar jihadist attacks in the past 16 years. Danger zones: mapping Europe’s earthquakes. A deeper understanding and better communication of earthquake risk has been a major challenge in geosciences for a long time.

Danger zones: mapping Europe’s earthquakes

The Global Earthquake Model initiative aims to become the world’s most complete source of earthquake risk resources and works towards a globally accepted standard for risk assessment. As part of this collaborative initiative, the EU-funded SHARE (‘Seismic Hazard Harmonization in Europe’) project helped in generating the first consistent regional seismic hazard model for Europe (including Turkey). The model, published in 2013, overcomes the limitation of national borders and includes a thorough quantification of the uncertainties. Seismic hazard data collected for this model consisted of records from more than 30,000 earthquakes with a magnitude of 3.5 and above on the Richter scale which occurred since the year 1000, as shown in the smaller map in this feature.

Tropical cyclonic systems are generally referred to as tropical storms.

Storm Spaces - Views of the World

They are better known by their regional names, such as hurricanes in the Caribbean and North America, or typhoons in parts of Asia. They form near the equator over larger bodies of warm waters that evaporate from the ocean surface and fuel these emerging storm systems. Their strong winds and heavy rainfalls frequently become part of our news as they often put large numbers of human livelihoods at risk. Recent studies show that the number of tropical cyclones (as well as tropical cyclone intensity) over the past decades has increased. Tracks of tropical storms collected over a longer period can indicate where such storms occur most frequently. (click for larger version) For this cartogram, the observed tracks of storms in that period were analysed and their frequency and intensity was plotted onto a grid which provided the basis for the map transformation.

Scientists have asserted for years that climate change may represent one of the greatest long-term threats to the global population.

How Climate Change Enables the Growth of Terrorism

With rising sea levels, destructive weather events, and drought, many believe that damage from climate change may be more imminent than first thought. However, critics persist. Though climate change is certainly a concern, many say other threats such as overpopulation, radical extremism, and political instability should be of higher priority. But what if these global threats were one and the same? Over the past year, prominent political figures, including President Barack Obama and Senator Bernie Sanders (VT), have made controversial statements regarding such a link. For many, this seems like a reach. It turns out the connection might be more obvious beneath the surface.

Les catastrophes naturelles ont déplacé 19,3 millions de personnes en 2014. Le | • Mis à jour le | Par Laetitia Van Eeckhout En 2014, 19,3 millions de personnes ont été obligées de fuir leur foyer en raison de catastrophes liées aux aléas naturels, révèle le dernier rapport de l’Observatoire des situations de déplacements internes (IDMC) du Conseil norvégien pour les réfugiés.

Les catastrophes naturelles ont déplacé 19,3 millions de personnes en 2014

Si les tremblements de terres et les irruptions volcaniques ont entraîné la mobilité de 1,7 million de personnes, dans leur très grande majorité ces déplacements ont été provoqués par des catastrophes liées aux aléas climatiques, des cyclones et des inondations essentiellement. Ebola. THE first reported case in the Ebola outbreak that has ravaged west Africa dates back to December 2013, in Guéckédou, a forested area of Guinea near the border with Liberia and Sierra Leone.


Travellers took it across the border: by late March, Liberia had reported eight suspected cases and Sierra Leone six. By the end of June 759 people had been infected and 467 people had died from the disease, making this the worst ever Ebola outbreak. As of July 5th 2015, 27,609 cases and 11,261 deaths had been reported worldwide, the vast majority of them in these same three countries. The outbreak continues to claim lives, though the casualty rate has abated this year. Liberia was declared Ebola-free on May 9th this year, but routine surveillance detected a new case on June 29th infected from an unknown source. The rate at which cases give rise to subsequent cases, which epidemiologists call R0, is the key variable in the spread of Ebola.

Ian Geldard sur Twitter : "Red lines show impact 'coridors' where asteroids are likely to hit... Visualizing 100 Years of Earthquakes. My last post was about the 1960 Chile megathrust earthquake, and how much energy it released (about 1/3 of all seismic energy on earth over the last 100 years). I used data from USGS on all earthquakes greater than magnitude 6 from 1915-2015. Since I had this nice dataset (about 10,500 quakes), I could not resist playing around in CartoDB to make some nice visualizations. This is an animated map of all earthquakes since 1915 using the Torque function in CartoDB. Recherche minières Silfiac et Loc Envel [12/06/15] This map shows where the strongest earthquakes are expected to strike. Munmun Mukherjee is a good patient. She lies quiet on the white stone delivery table of the government hospital in Kolkata, but for an occasional low moan.

Even this is muted, the edge of her voice flattened, as if she knows that she needs to be on her best behaviour. A slim, dusky woman, she looks tidy even in her tired, crumpled nightie. It is late January, and the reluctant Kolkata winter has already slipped away. Deep in the fold of the evening, there is a warm traffic of activity inside the labour room of this large hospital. The table alongside Munmun is empty, a brown blood stain in the middle has seeped in so obstinately that it looks like a marbled pattern. Munmun is the only patient in the room, her stone table is hard and cold to the touch. Nepal Earthquake Swipe Map & Satellite Images. New Global Terrorism Map shows 35 years of terror incidents.
