Supervolcanoes are one of nature’s most destructive forces, but given that there are no recorded observations of super-eruptions — the last occurred 74,000 years ago in Indonesia — scientists don’t fully understand how they work. Now a team studying the world’s fastest-inflating volcano, Bolivia’s Uturuncu, is shedding some light on how supervolcanoes become so powerful.

A mineral assessment milestone confirms world-class resources

Each donning about 10 kilograms of protective gear, including helmets and Kevlar, scientists trudged up the rugged, rocky volcanic terrain of southern Afghanistan, slowing now and then to catch an extra breath of thin air. Some carried guns. Others carried rock hammers.

Usually, when a major natural disaster strikes, a population becomes more alert and aware. People know what warning signs to watch for; they know what to do should such an event occur again. They increase their chances of staying alive. For example, intergenerational knowledge of tsunamis passed down by island tribes around the Indian Ocean is credited with saving lives during the 2004 Indian Ocean tsunami.

During the past year, many of the 386,000 inhabitants of New Zealand’s second-largest city, Christchurch, have thought and said one phrase over and over again: “When will it stop?” Starting in September 2010, several major earthquakes and more than 8,000 aftershocks have rocked the city and region. Rebuilding has started, been interrupted, started again and been halted again. People have been living without water, sewer, roads, offices and homes for so long that it may be hard to remember what “normal” is.

In recent years, climate scientists, particularly those involved in communicating the risks of anthropogenic climate change to the public, have faced increasing levels of vitriol from politicians, pundits and the public alike. The news earlier this year that leading Australian climate scientists were receiving death threats, in the midst of a fierce debate on the implementation of a carbon tax, is just the latest escalation.

Since their introduction in the early 1980s, geotextile structures have gained popularity in the engineering community and are now being used for a variety of geotechnical engineering applications. Geotextiles were originally developed as permeable reinforcement for soils in landscape applications. Woven and nonwoven geotextiles, known for their strength and permeability, are typically made from the synthetic polymers polypropylene and polyester, but natural fibers like coir and jute are becoming more popular.

Researchers flying over West Antarctica last month were at the right place at the right time, spotting an actively growing rift that they expect will spawn an iceberg about 10 times the size of Manhattan.

By Tuesday evening local time, close to 500 people have been confirmed dead and more than 1,300 injured following a major magnitude-7.2 earthquake that struck eastern Turkey on Sunday at 1:41 p.m. local time. Countless people are still trapped under debris after the shallow quake, only 20 kilometers deep, leveled at least 2,260 buildings in Van, Ercis and other cities and villages, according to news reports.
