Hidden double earthquake spells trouble for tsunami-warning systems

On Jan. 2, 2011, a magnitude-7.1 earthquake was recorded striking central Chile along the tectonic boundary between the Nazca and South American plates. Shaking from the quake was felt hundreds of kilometers from the epicenter, but no deaths or major damage were reported.

Himalayas get a new birthdate

The Himalayas are the highest and widest mountain range on the planet, but when they began forming has never been clear. In a new study, researchers have now pinpointed the date of the initial collision between India and Eurasia that led to the birth of the Himalayas.

Getting there and getting around Jordan

Jordan has two international airports: Amman and Aqaba. Amman’s Queen Alia International Airport is the main gateway, offering service to most major Middle Eastern and European cities and regular nonstop flights to New York, Chicago and Montreal. The airport is located 35 kilometers south of Amman; reach the city via express bus service or taxi. Taxis also serve Madaba, which is much smaller and closer to the airport. Madaba hotels will arrange airport pickup and King’s Highway transportation for you. The most convenient and flexible exploration option is with your own vehicle. Several rental agencies operate in Madaba, with more selection at the airport. Our vehicle was delivered to our Madaba hotel, allowing us to avoid city driving in Amman. Signs are generally in both Arabic and English.

Parasites of the Paleozoic

Parasitism — an ecological relationship in which one species benefits at the expense of its host — is common among living organisms, but as most parasites are soft-bodied, it’s rare to find them preserved in the fossil record. Two recent discoveries, however, have lengthened the short list of ancient parasites

Geomedia: Books: The danger of anti-data ideologies is explored in 'Denying Science'

I see science denialism as a pernicious problem in modern society. It was with some anticipation, then, that I recently read John Grant’s 2011 book “Denying Science.” In it, I found a mix of indignation and new information, as well as a lot with which I was already familiar.

How supervolcanoes are set off

If a supervolcano were to erupt today, its impacts could be catastrophic. Fortunately, no such eruption has occurred during human history. The lack of eyewitness accounts, however, makes it difficult for scientists to understand how supervolcanoes evolve and erupt. Based on a recent modeling, researchers have offered a new hypothesis for how supervolcano eruptions might be triggered by external, rather than internal, forces.

Mammoths may have suffered from bone disease

The demise of mammoths, which went extinct by the end of the Pleistocene about 12,000 years ago, is thought to have been brought about by a combination of climate change and overhunting by early humans. A new study indicates that another culprit might have contributed as well: Mammoth bones retrieved from Northern Eurasia — from sedimentary strata close to the animals’ last known appearance in the fossil record — appear to show evidence for bone diseases associated with nutrient deficiencies.
