The race to contain West Africa's Ebola outbreak (Wired UK)

The race to contain West Africa's Ebola outbreak (Wired UK) | Complex Insight  - Understanding our world | Scoop.it
Digital volunteers are racing to map regions in West Africa where the Ebola virus, which has a 90 percent fatality rate, continues to spread
ComplexInsight's insight:

The use of OpenStreetMap (OSM) as an unifying geodata system is increasing in humanitarian aid. The current Ebola outbreak in West Africa is a challenge at multiple levels for teams trying to coordinate a response. Due to years of war there are few up to date maps in the region and multiple boundaries mean different groups are collecting data. Digital volunteers creating new OSM entries will be a key asset in enabling health officials to manage the outbreak and hopefully bring things under control.

Computer Graphics World - Earthquake Acoustics Can Indicate If Massive Tsunami Is Imminent

Computer Graphics World - Earthquake Acoustics Can Indicate If Massive Tsunami Is Imminent | Complex Insight  - Understanding our world | Scoop.it

Stanford scientists have identified key acoustic characteristics of the 2011 Japan earthquake that indicated it would cause a large tsunami. The technique could be applied worldwide to create an early warning system for massive tsunamis.

ComplexInsight's insight:

Computer simulations by Stanford scientists reveal that sound waves in the ocean produced by the earthquake probably reached land tens of minutes before the tsunami. If correctly interpreted, they could have offered a warning that a large tsunami was on the way. Click on the image or title to learn more.

US quake linked to oil wastewater

US quake linked to oil wastewater | Complex Insight  - Understanding our world | Scoop.it
Scientists link drilling-operation wastewater injection to a magnitude-5.7 earthquake that struck the US state of Oklahoma in 2011.
ComplexInsight's insight:

Wastewater injection from drilling operations has been linked to seismic events in the past but a new study in Geology (http://bit.ly/YEpbIn) suggests that there are long term effects that have previously not been considered.

Cave holds stunning tsunami clues

Cave holds stunning tsunami clues | Complex Insight  - Understanding our world | Scoop.it

A cave on the northwestern coast of Sumatra holds a remarkable record of big tsunamis in the Indian Ocean. Scientists are using the site to help determine the frequency of catastrophes like the event of 26 December 2004.

ComplexInsight's insight:

Sumatra's proximity to the Indo-Australia and Sunda tectonic plate boundary, and the giant earthquakes that occur there, means its shores are at risk of major inundations.Understanding how often these occur is important for policy and planning in the region. In the floor of the cave, encoded in the depositions of sand between layers of bat guano is a tsunami record providing detailed event histories from about 7,500 to 3,000 years ago that helps show the frequency of tsunamis in the region.

Limited Urban Growth: London's Street Network Dynamics since the 18th Century

We investigate the growth dynamics of Greater London defined by the administrative boundary of the Greater London Authority, based on the evolution of its street network during the last two centuries. This is done by employing a unique dataset, consisting of the planar graph representation of nine time slices of Greater London's road network spanning 224 years, from 1786 to 2010. Within this time-frame, we address the concept of the metropolitan area or city in physical terms, in that urban evolution reveals observable transitions in the distribution of relevant geometrical properties. Given that London has a hard boundary enforced by its long standing green belt, we show that its street network dynamics can be described as a fractal space-filling phenomena up to a capacitated limit, whence its growth can be predicted with a striking level of accuracy. This observation is confirmed by the analytical calculation of key topological properties of the planar graph, such as the topological growth of the network and its average connectivity. This study thus represents an example of a strong violation of Gibrat's law. In particular, we are able to show analytically how London evolves from a more loop-like structure, typical of planned cities, toward a more tree-like structure, typical of self-organized cities. These observations are relevant to the discourse on sustainable urban planning with respect to the control of urban sprawl in many large cities which have developed under the conditions of spatial constraints imposed by green belts and hard urban boundaries.

Dino-killing asteroid also triggered mind-blowing submarine landslides | Complex Insight  - Understanding our world | Scoop.it
Huge deposits identified in Gulf of Mexico and beyond.
ComplexInsight's insight:

Arsttechnica article describing research published in Geology where researchers used publicly available data from 33 deep wells drilled by the oil and gas industry in the Gulf of Mexico combined  with seismic images of the region to identify massive Seafloor 'landslides' which occured as the result of the Chicxulub impact. The asteroid impact which ended the reign of the dinasaurs shook loose sediment along well over 2,000 miles of submarine slopes along the east coast of the United States as well as the Gulf of Mexico. Link to the orginal Geology paper at the end of the article.
