European seismic hazard map

Europe has a long history of destructive earthquakes, and seismic risk can severely affect our modem society, as recently shown by the 1999 Izmit (Turkey) and the 2009 L'Aquila (Italy) events. Seismic hazard defines the likelihood of ground shaking associated with the occurrence of earthquakes. Assessing seismic hazard is the first step to evaluate seismic risk, the likelihood of damage and loss for the area of interest depending on vulnerability factors (e.g„ the type, age and value of buildings and infrastructures. population density, and land use). High hazard does not necessarily imply high risk: frequent large earthquakes result in high hazard but pose limited risk if they shake remote areas, while moderate earthquakes in densely populated areas may entail high risk.

The collaborative project ‘Seismic Hazard Harmonization in Europe (SHARE)" was supported by the EU-FP7 to deliver the first-ever complete, state-of-the-art hazard model, replacing older maps (ESC-SESAME. 2003). SHARE contributes its results as a regional program to the Global Earthquake Model (GEM) program initiated by the Organization for Economic Cooperation and Development.

The SHARE hazard results describe potential shaking associated with future earthquakes in Europe and serve as input for mitigation policies such as seismic risk assessment and earthquake-resistant design, covering single- and multi-storey buildings and critical infrastructures such as bridges or dams. Through coordination at the European Union level, these hazard results will help harmonize the next generation of national seismic hazard assessments and serve as a benchmark for the revision of the European seismic building code (EuroCode8). The data assembled by SHARE on earthquakes and faults will accelerate the generation of new scientific and technical knowledge to improve seismic hazard assessment in Europe.

European seismic hazard map
The European Seismic Hazard Map displays the ground shaking (i.e. Peak Horizontal Ground Acceleration, PGA) to be reached or exceeded with a 10% probability in 50 years. This reference value represents the shaking to be expected during the human lifetime in an standard building, corresponding to the average recurrence of such ground motions every 475 years, as prescribed by the national building codes in Europe. It’s important to note that these values can be exceeded with a 10% probability every 50 years.

The ground shaking is expressed in terms of the unit gravitational acceleration g. The SHARE peak ground acceleration value across Europe range from 0g to over 0.5g. Low hazard areas (PGA≤0.25g) in red-black.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moo

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray fox
