| Contorted oceanic plate caused complex quake off New Zealand’s East Cape Posted: 27 Dec 2021 12:43 PM PST Researchers used a novel finite-fault inversion method with seismometer data from around the world to investigate a deep intraslab earthquake that occurred on March 4, 2021, off the northeastern tip of New Zealand's North Island. This imaging revealed complex rupture geometry that included shallow faulting with trench-perpendicular extension and unusual deep faulting with trench-parallel compression, possibly caused by seamount subduction and/or the transition between the Kermedec Trench and Hikurangi Margin, with different thicknesses of subducting oceanic crust. |
| 'Nano-chocolates' that store hydrogen Posted: 27 Dec 2021 12:43 PM PST An innovative approach could turn nanoparticles into simple storage devices for hydrogen. The concept uses nanoparticles made of the precious metal palladium. |
| Controlled burning of natural environments could help offset our carbon emissions Posted: 23 Dec 2021 08:31 AM PST Planting trees and suppressing wildfires do not necessarily maximize the carbon storage of natural ecosystems. A new study has found that prescribed burning can actually lock in or increase carbon in the soils of temperate forests, savannahs and grasslands. |
| Remote areas are not safe havens for biodiversity, research shows Posted: 22 Dec 2021 07:08 AM PST Remote localities are generally considered as potential reservoirs for biodiversity, but this is just part of the story. With regard to fish communities, researchers have produced a global map of risk that shows that no place is safe, regardless of distance from humans. |
