Benchmarks: November 8, 2013: Super-typhoon Haiyan tests Philippines warning protocols

On the morning of Nov. 8, 2013, Super-Typhoon Haiyan struck the east-central Philippines with sustained wind speeds exceeding 300 kilometers per hour. In a mere eight hours, the storm cut a path of total devastation over an area of 300 square kilometers, an area roughly the size of Seattle. More than 7,800 people were confirmed dead or missing and 27,000 injured; more than 4 million were displaced from their homes. Economic losses to homes, infrastructure and agriculture reached more than $12 billion (U.S.).

Mineral Resource of the Month: Zeolites

Zeolites comprise a group of silicate minerals with very open crystalline structures that make them suitable for catalytic, ion exchange and molecular sieving applications. Aluminum, silicon and oxygen atoms are arranged in a 3-D framework of channels and cages. Water molecules and cations, such as calcium, sodium, potassium and magnesium, occupy these interconnected channels and cages. The cations can readily substitute for one another, and water molecules may be gained or lost without any major changes to the basic zeolite crystal structure.

Down to Earth With: Molecular biologist Sarah L. Anzick

In May 1968, when Sarah L. Anzick was 2 years old, the 12,600-year-old remains of a male toddler were discovered at the base of a bluff on her family’s ranch near Wilsall, Mont. The Anzick infant — one of just a handful of ancient skeletons to have been found in North America and the only known Clovis burial site —  had been carefully buried with more than 100 stone and bone tools.

Benchmarks: October 10, 1913: Atlantic and Pacific waters meet in the Panama Canal

On Oct. 10, 1913, U.S. President Woodrow Wilson pressed a button in his Washington, D.C., office. At that moment, more than 6,400 kilometers away, about seven metric tons of dynamite exploded, clearing the final obstruction in the Panama Canal. Deep within the Culebra Cut, waters from the Atlantic Ocean finally met waters from the Pacific Ocean, marking the end of major construction on the 77-kilometer-long canal.

Benchmarks: October 9, 1963: The Vajont Landslide kills 2,500 in Italy

In 45 seconds, everything changed. What had been a towering mountainside collapsed into a pile of rubble; what had been a deep reservoir of placid water became a lethal flood; what had been a valley of small Italian villages was leveled to a barren outwash plain.

Mineral Resource of the Month: Vermiculite

Vermiculite comprises a group of hydrated, laminar magnesium-aluminum-iron silicate minerals resembling mica. They are secondary minerals, typically altered biotite, iron-rich phlogopite or other micas or clay-like minerals that are themselves sometimes alteration products of amphibole, chlorite, olivine and pyroxene. Vermiculite deposits are associated with volcanic ultramafic rocks rich in magnesium silicate minerals, and flakes of the mineral range in color from black to shades of brown and yellow. The crystal structure of vermiculite contains water molecules, a property that is critical to its processing for common uses.

On the Web: Personalizing drought data with digital tools

One of the hardest parts of hazard mitigation is communicating risk to the public. With drought, people feel the heat while it’s happening but understanding how the current drought fits into past trends — and their implications for the future — is harder to grasp. Now, several online tools are available to help the public and decision-makers look at drought data.

Benchmarks: September 1, 1957: Fossil Cycad National Monument is dissolved

On Sept. 1, 1957, with the stroke of a pen, the U.S. Congress declared Fossil Cycad National Monument in the Black Hills of South Dakota to be no more. At one time, the site held the world’s largest collection of rare fossil cycad-like plants that thrived during the Cretaceous. Over the years, mismanagement, vandalism and theft left the site barren of fossils — the site never had a staff or visitor center, and was never opened to the public. The site’s initial designation as a national monument, in October 1922, had been brought about by the crusading of one man, Yale University paleobotanist George R. Wieland; in the end, he was also responsible for its demise.
