Q&A: What has been done to the design of buildings to reduce damage and injury to earthquake prone areas?
Question by CJ: What has been done to the design of buildings to reduce damage and injury to earthquake prone areas?
Many people live in earthquake areas. What has been done to the design of buildings to minimize damage and injury. Any answers would be appreciated . Thanks

One of the simplest adaptations is to build sturdy buildings out of wood, rather than brick or stone. Wooden buildings can naturally flex more to dampen the oscillations associated with an earthquake, whereas a brick structure would be more prone to crumble.
There are high-tech solutions too, employed in, for example, tall buildings in cities. Large masses with some degree of constrained movement can help dampen the motion of an earthquake. Alternatively or additionally, there may be measures taken to construct building that are partially decoupled from the ground (eg, on rollers), so that if an earthquake occurs, only a fraction of its energy is transferred into the building.
On a related note, one of my favourite examples of construction around tectonic or seismic events is the Alyeska Pipeline in Alaska. Where the pipeline crosses the Denali fault, it’s built on rails, so that if there is any fault offset (such as there was in the 2004 Denali Earthquake), the pipeline will slide and escape serious damage.

Chilean students have taken over schools and city streets in the largest protests the country has seen in decades. These actions are causing a political crisis for the country’s billionaire President, Sebastian Piñera. The students are demanding free education, and an end to the privatization of their schools and universities. The free-market based approach to education was implemented by the military dictator Augusto Pinochet in his last days in power. As the demonstrations in Chile coincide with protests erupting globally, Fault Lines follows the Chilean student movement during their fight in a country that is among the most unequal in the world.
