L’Aquila earthquake of 2009 offers lessons in disaster response

By analysing previous disasters, lessons learnt can be incorporated into policies and plans to manage the effects of future disasters. A recent study examining the 2009 L’Aquila earthquake in Italy suggests that although the national response effectively dealt with the emergency, longer-term measures to help local populations cope with the aftermath of the disaster need to be set out more clearly.

Earthquakes as well as climate change responsible for sea-level rise

Satellite data from the Torres Islands in the southwest Pacific suggest that rising sea-levels in the region widely attributed to climate change is also partly caused by sinking of the islands following earthquakes in the 1990s, according to recent research.

Scientists calculate risks of further earthquakes from gas drilling in Groningen, the Netherlands

A recent overview and analysis shows that increasing amounts of gas drilling at Groningen, the largest gas field in Europe, led to a dramatic rise in regional earthquakes between 2001 and 2013. After a reduction in extraction was introduced by the Dutch Government, earthquake numbers started to fall. Statistical analysis reveals that if high extraction rates were resumed, about 35 earthquakes, with a magnitude (M) of over 1.5 on the Richter scale, might occur annually from the year 2021 onwards, including four with a damaging magnitude of over 2.5.

A circular economy for earth metals in industrial waste: the politics of vanadium

A successful circular economy for valuable metals needs more than just effective recycling technologies, as a new study shows. The research, which explored the governance of recovering vanadium from steel-industry waste, revealed that industry stakeholders feel the prospect of financial gain, or reduced costs, through recovery is too distant at present. This perception could hinder a circular economy for critical materials from industrial residue, the study warns.

Recycled waste could be a valuable source of rare earth elements

Recycling offers a promising means of supplying the rare earth elements neodymium and dysprosium, used in computing and low-carbon technologies, research suggests. If recycling infrastructure and technologies are prepared now to deal with the larger volumes of high-tech waste expected in the future, 7-9% of global demand for these critical elements could be met by recycling by the year 2030.

NASA's THEMIS sees Auroras move to the rhythm of Earth's magnetic field

The majestic auroras have captivated humans for thousands of years, but their nature -- the fact that the lights are electromagnetic and respond to solar activity -- was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.

Spanish earthquake triggered by groundwater pumping

An earthquake that killed nine people in Lorca, Spain, last year could have been triggered by groundwater being drained from the area for use in irrigation, according to scientists. The study found that the ground moved in the same places as subsidence has been occurring since the 1960s, due to the extraction of groundwater.

Underground wastewater disposal in the US linked to increase in earthquakes

The number of earthquakes of magnitude 3 or greater in the central and eastern US has increased significantly in recent years, from about 21 a year between 1967 and 2000, to over 300 between 2010 and 2012. Most of this increase seems to be linked to the deep injection of wastewater in underground wells, according to a recent review of seismic activity.

How will biodiversity loss compromise Earth's life support systems?

Scientists have evaluated two decades of research into declining biodiversity and concluded unequivocally that loss of species richness leads to a reduction in how well ecosystems function. The researchers evaluated the evidence for key biodiversity theories and predicted that scientific progress in the next five to ten years will provide the information we need to efficiently conserve certain ecological processes.

Vertebrate population losses and declines: Earth’s ongoing mass extinction may be more severe than previously estimated

A new study suggests that Earth’s ongoing mass extinction episode is more severe than generally perceived. Rather than focusing on the complete extinction of entire species, researchers analysed the losses and declines of populations in a sample of 27 600 vertebrate species. Population declines and losses are often a prelude to species extinctions. Researchers also conducted a more in-depth analysis of population losses between 1900–2015 in 177 mammal species. The results reveal that rates of population loss and decline in vertebrates are extremely high, even in common “species of low concern”. The data indicates that, in addition to significant species extinction rates, the Earth is experiencing a huge episode of population decline and loss, which will have a significant effect on ecosystem functioning and services. The researchers warn that the window for effective action is closing rapidly and emphasise the need for an urgent response.

Mussel study determines risk posed by rare earth metals to marine environments

Rare earth elements (REEs) are used increasingly often in innovative technologies, causing these elements to enter the natural environment. They can be sourced via deep-sea mining, raising concerns about marine exposure to mining processes and waste products. This study examined how two REEs, lanthanum and yttrium, affected and stressed marine ecosystems, using young marine mussels (Mytilus galloprovincialis) as indicators of water quality. The researchers determine a parameter known as the ‘predicted no effect concentration’ (PNEC) for La and Y — the maximum environmental level of each of the two elements at which no effect is seen on the most sensitive organisms and which is, therefore, deemed safe for the environment.

Earthworms are essential for soil quality, reducing crop pathogens and ensuring yield

Soil biodiversity, soil quality, and soil health are integral to protecting the natural environment. Soils are crucial to food production and human well-being, as highlighted by the UN Sustainable Development Goals (SDGs). The abundance of soil biota is of great importance for the provision of associated ecosystem services (ES) and fundamental driver of self-regulation in soil. This study explores how the presence, or absence, of earthworms affects aspects of crop health and productivity, focusing on their shielding of winter wheat from the toxic plant fungi Fusarium.
