Earthquakes in the Classroom

"An 8.2-magnitude earthquake struck off the coast of northern Chile, generating a local tsunami.  The USGS reported the earthquake was centered 95 km (59 miles) northwest of Iquique at a depth of 20.1km (12.5 miles).  This video gives the context for this type of earthquake."

I woke up this morning to news of a large earthquake in Chile (security camera video footage).  IRIS (Incorporated Research Institutions for Seismology) creates teaching resources for teachers who want to use the current events such as yesterday's earthquake in Chile as an opportunity to discuss earth's physical systems and how they impact humanity.  They've produces slides, animations and PDFs for classroom use all while you were sleeping last night.

Video - Walking to Safety - artificial hill as tsunami refuge

GeoHazards International is working with community leaders in Padang, Indonesia, to help prepare the city for a likely tsunami through the construction of elevated parks, called TEREPs.

Video - Gigantic Rockslide in Randa (Matter valley, Switzerland, 1991)

On 18 April 1991, around 15 million m3 of rock slid down to the valley near the town of Randa which is located in the Matter Valley. The rocks were the size of houses and the drop height was 600 metres. The main cause of the rockslide was the effect of frost and thaw periods and increased water pressure in the rock fissures.

Jessica Rieman's curator insight, February 11, 2014 1:27 PM

This graph depicts the estimated population growth throughtout the years of 1950-2100. Age has a lot to do with the increasing rate by millions. The people that are 65+ represented in the green are "peaking old" at 2080. As for the 15-64 age braket they are represented in the red and are reaching the "Adult peak" at the year 2030. And lastly, the "Peak Child" is represented in the blue achieves that in 1990. All of these statistics stem from the Brazilian records and are relative to the daily life and climate of the specific group or individual.

Albert Jordan's curator insight, February 12, 2014 5:56 PM

Looking at the statistics for South America’s growth rate since 1950, it has grown rapidly. This rapid growth can easily be attributed to modernization, increased stability within the governments(even if corruption is still rampant in some places and the U.S. isn’t fiddling its fingers in politics or funding government overthrows), and increased outside development thanks to increased global globalization. While total population of the region is expected to rise until it peaks in 2050, so is population density and age. This will create sanitation, infrastructure, and healthcare issues that many parts of the continent may not be ready to address or able to. Even though economic strength is typically on the rise, these are still poorer developing nations. The birthrate is already beginning to peak and taper off even if deaths continue to rise. However, there is still predicted to be more births than death. Improved healthcare globally since 1950 has found its way into South America and so has economic output, bringing with it – immigration. Numbers such as South America’s can be used to create a visual representation by using a population pyramid to figure out which phase of the demographic transition model the region, or with more specific numbers, a country was in, is going into, and will predicable be in.

Zuid-Soedan in 9 vragen en antwoorden...

Zuid-Soedan in 9 vragen en antwoorden... | Geografie Onderbouw | Scoop.it

De crisis in dit betrekkelijk  jonge - bestuurlijk gezien- gebied is ongeveer 2 weken aan de gang. Mogelijk dat het escaleert  en er een burgeroorlog ontstaat. Er zijn al honderden dodelijke slachtoffers en meer dan 100.000 vluchtelingen, naast aanvallen op en slachtoffers bij de VN troepen.
Wat er nu precies speelt en welke belangen er mee gemoeit zijn is soms onduidelijk. Deze 9 antwoorden geven hierop enig zicht, maar zijn niet dekkend ook al om dat het conflict steeds verder gaat in tijd en ruimte.

Sad what's going in South Sudan but worth learning about it.

Cam E's curator insight, March 4, 2014 11:50 AM

New countries rarely establish themselves without a trying conflict or struggle in their infancy. I always like this simplified articles which introduce the latest conflict to people who are unaware. Ethnic groups are fluid in their importance throughout the world. It wasn't long ago on the historical scale that Irish Americans and British Americans were at odds, despite us in the US rarely considering that today. Ethnic conflict never ceases completely, but shifts targets depending on the politics of the time.

Tracy Galvin's curator insight, May 5, 2014 2:39 PM

Without the big bad north to be their common enemy, the two ethnic groups in South Sudan are now fighting each other. In places like these with such limited resources there will always be internal conflicts

Infographic - natural disasters are more frequent than 30 years ago - and are costing us more | Geografie Onderbouw | Scoop.it
Munich Re, one of the world's biggest reinsurance companies, has compiled data on the cost of natural disasters since 1980. It shows that the Japanese quake was the costliest disaster of all time, with losses of $210 billion - not including the nuclear incident at Fukushima. More broadly, the figures reveal a clear rise in the financial losses associated with natural disasters over the past 30 years.

What are the world’s riskiest cities when it comes to natural disasters? For the insurance industry it seems an ever-more urgent question, so last year one reinsurance company set out to assess 616 cities around the world for their risk of earthquake, hurricanes and cyclones, storm surge, river flooding and tsunami. Here are Swiss Re’s overall top 10 most risky cities

The World's Most Densely Populated Cities

The World's Most Densely Populated Cities | Geografie Onderbouw | Scoop.it
“ The growth of these cities will create a host of environmental and health problems.” By 2210, the global population is expected to grow from just more than 7 billion to 11.3 billion — with 87 percent of the population living in urban areas, according to a new working paper by researchers from NYU’s Marron Institute. Most of these individuals will be in what’s now the developing world — creating a host of environmental and health problems. If projections are correct, these new urban dwellers will require the world’s existing cities to expand six-fold to accommodate triple the residents, Richard Florida wrote in The Atlantic. Plus, the world will need 500 new “megacities” of 10 million or more, he wrote.

The Growth of Megacities

The Growth of Megacities | Geografie Onderbouw | Scoop.it

"For the first time in human history, more of the world’s 6.8 billion people live in cities than in rural areas. That is an incredible demographic and geographic shift since 1950 when only 30 percent of the world’s 2.5 billion inhabitants lived in urban environments.

 

The world’s largest cities, particularly in developing countries, are growing at phenomenal rates. As a growing landless class is attracted by urban opportunities, meager as they might be, these cities’ populations are ballooning to incredible numbers.

 

A May 2010 Christian Science Monitor article on “megacities” predicted that by 2050, almost 70 percent of the world’s estimated 10 billion people—more than the number of people living today—will reside in urban areas. The social, economic and environmental problems associated with a predominantly urbanized population are considerably different from those of the mostly rural world population of the past."

Whitney Souery's curator insight, May 28, 2014 6:48 PM

The majority of megacities are in the developing world, with the exception of places like New York and Tokyo, best showing how the face of the world is changing. Developing countries are on their paths to becoming major powers, such as Calkutta for example. As an enlarging city, more and more citizens are flocking to the abundance of jobs in the city which thus increases India's development as a result of the growing city and thus leads to a cycle of growth as demand for more jobs increases as the city grows. Megacities are thus a symbol of the developing world and can be used in human geography as symbols of development.
