NEWSBREAKERS
New Zealand faces more movement
A magnitude 6.5 earthquake recently rattled the New Zealand capital Wellington at the South end of the North Island while the northern South Island township of Seddon sustained damage. Seismic data suggests the earthquake was related to NE-SW right-lateral strike-slip motion, consistent with plate motion oriented displacements and the Marlborough Fault system which has cut the northern South Island into a series of crustal blocks. This region of New Zealand has seen numerous earthquakes in recent weeks. Seismic data indicates movement on shallow upper plate structures aligned NE-SW, and some deeper subduction-related activity off shore of the South Island's north coast.

IN THE NEWS
Phosphorus cycle broken?
A new mathematical model suggests that rapid megafauna extinction could result in a 98% reduction in the dispersal of phosphorus throughout the ecosystem. Applied to the Amazon Basin researchers concluded strong decreases in phosphorus availability in eastern Amazonia, away from fertile floodplains, probably occurred as a result of the sudden disappearance of the local megafauna 12,000 years ago and that the decline may still be ongoing.

... and on that note: Recent research suggests the vegetation shift to more fire-prone species seen in Australia around 45,000 years ago was not the cause of the Australian megafaunal extinction but was the consequence of the extinction of the large browsers.

Late Jurassic mammal unearthed
A new Jurassic multituberculate fossil from China shows adaptations for omnivorory and skeletal features that appear to be ancestral to all multituberculates, including features important to the later success of the multituberculates in the Cretaceous and Paleogene. The rat-like mammal was found preserved in lake sediments, suggesting that it lived on or near the shores of lakes and rivers.

Vanuatu Vog
Vanutu's Ambrym Island volcano shows its two active craters, Benbow (left) and Marum (right), both continuously venting steam, sulfur dioxide, and other volcanic gases. Also visible in this image is Marum's persistent lava lake. This natural-colour image was acquired by the Advanced Land Imager (ALI) on August 9, 2013.

IN THE MEDIA
Zircon chemistry marks megafloods
About two million years ago giant lakes were formed behind glacial dams inland of the Himalayas. When the ice dams failed these lakes caused mega-flash-floods downstream in India's Assam Valley and beyond. Zircons in the megaflood deposits match zircons known to come only from Namche Barwa, a mountain peak adjacent to Tsangpo Gorge. Finding the zircons in deposits far downstream is evidence for the path of some prehistoric megafloods and the role these particular events played in forming this gorge, possibly one of the deepest in the world.

A pain in the neck for museums
Studies into the effects of muscle and cartilage on the flexibility of ostrich necks has implications for sauropod dinosaur reconstructions. The work suggests computer simulations of sauropod movements have not portrayed neck flexibility accurately and that museum animations and static displays will need to be rethought as a result.
