Database of earthquakes triggered by human activity is growing — with some surprises

Public Release: 28-Sep-2017   Seismological Society of America The Human-Induced Earthquake Database (HiQuake), the world’s most complete database of earthquake sequences proposed to have been triggered by human activity, now includes approximately 730 entries, according to a report published October 4 in the “Data Mine” column of the journal Seismological Research Letters. Mining projects (37%)…

Virus reprograms ocean plankton

Public Release: 21-Aug-2017 University of Exeter A virus which infects ocean plankton can reprogramme cells and change the way they absorb nutrients – potentially changing how carbon is stored in the ocean, new research shows. Scientists from the University of Exeter have examined the DNA of the OTV6 virus, which infects phytoplankton (plant-like microbes which…

Burying Greenhouse Gas a Viable Idea, Study Finds

  By SEAN DUFFY       (CN) — Storing massive amounts of carbon dioxide underground may be a more effective tool for limiting global climate change than previously thought, a study released Thursday says.     The study, published in the journal Nature Communications, shows the viability of plans to capture and store carbon in order to curb…

External noise produces volcanic seismicity, akin to a drumbeat

Public Release: 11-May-2015 Relatively small external disturbances play a crucial role in chaotic phenomena like the recent Calbuco volcanic eruption in Chile, leading to drum-beat-like seismicity Springer Volcanoes are considered chaotic systems. They are difficult to model because the geophysical and chemical parameters in volcanic eruptions exhibit high levels of uncertainty. Now, Dmitri V. Alexandrov…

Monarch Butterflies food supply 99% destroyed by Monsanto’s herbicide

  Friday, 06 February 2015 The multinational agricultural giant Monsanto’s signature herbicide Roundup Ready is leading to the decimation of Monarch butterfly populations, according to a report issued by the US environment watchdog Center for Food Safety. “This report is a wake-up call. This iconic species is on the verge of extinction, because of Monsanto’s…

Adjusting Earth’s thermostat, with caution

Harvard scientists say aspects of solar geoengineering can—and should—be tested without need for full-scale deployment November 17, 2014 Cambridge, Mass. – November 17, 2014 – A vast majority of scientists believe that the Earth is warming at an unprecedented rate and that human activity is almost certainly the dominant cause. But on the topics of…

Wastewater disposal may trigger quakes at a greater distance than previously thought

Man-made quakes need to be included in seismic hazard planning say experts SAN FRANCISCO, CALIF. – Oil and gas development activities, including underground disposal of wastewater and hydraulic fracturing, may induce earthquakes by changing the state of stress on existing faults to the point of failure. Earthquakes from wastewater disposal may be triggered at tens…
