Earthquakes

Youngstown, OH has experienced 11 quakes, including one rated 4.0, which may be tied to deep disposal wells for the water used in the hydraulic fracking process of natural gas drilling.

Michel Martelly is the newly elected president of Haiti. He faces the large challenge of rebuilding much of the country's population center, which was devastated by an earthquake in January 2010.

In California, some worry that the state's aging delta levees are in extreme danger of being destroyed by earthquakes. And as environmental concerns rise, the state is considering plans to re-engineer its water supplies to prevent another "Katrina".

Nearly five years after Hurricane Katrina devastated New Orleans, the bungled recovery effort offers lessons to Haiti and Chile as they recover from more recent natural disasters, according to this piece from Allison Arieff.

With the country is full recovery mode, urban planners in Haiti are releasing a strategy document that seeks to redistribute the population of damaged Port-au-Prince and to create a series of smaller urban centers throughout the country.

Officials in the Dominican Republic have approved the creation of cities made of home built out of shipping containers -- part of efforts to aid earthquake-rattled Haiti.

The leading architect and urban planner from the Philippines is calling on the city of Manila to take stronger precautions in the face of earthquakes and other natural disasters.

Port-au-Prince is not an outlier. Many other major cities in developing and poor countries lie along earthquake fault lines and are in danger of destruction.

More than a million Haitians have fled the capital city of Port-au-Prince, and government officials are advising them to stay out of the city. But many question if these provincial cities will be able to provide jobs and economic opportunities.

Every day since the earthquake that shattered Haiti earlier this month, a group of 50 planners, architects and developers have met to brainstorm and strategize the rebuilding of their country.

This episode of DnA wonders whether design and architecture will be able to help Haiti revive itself.

The event of a huge earthquake off the Aleutian Islands could send a devastating tsunami towards the West coast of the U.S. Researchers have released maps of what a worst-case scenario might look like for coastal communities.

Utilities officials in the San Francisco Bay Area are hoping to secure their water resources in the face of another devastating earthquake by building a 5-mile long water tunnel beneath the Bay.

Advances in material development have brought to the market a new type of concrete that can bend under pressure and heal cracks with the addition of water.

A California-based architecture firm has been selected by a Sichuan planning department to rebuild the city of Dujiangyan after the deadly earthquake in the province earlier this year.

Mark Kingwell observes the sharp -- and deadly -- contrast between shining Shanghai skyscrapers and the poorly-built prefab concrete structures in China's rural areas that proved to be deathtraps in the recent earthquake.

As rescue work continues in the aftermath of the earthquake in China's Sichuan province, many -- including the state-run media -- are asking questions about why so many buildings collapsed, and blame corruption and shoddy construction methods.

New earthquake hazard maps from the U.S. Geological Survey show increased earthquake risk areas beyond typical hotspots like California. Geologists say planners and local officials should react to the maps by updating building codes.
