Science Daily Natural Disaster News

Natural Disaster News and Research. Earthquakes, volcanic eruptions, landslides, tsunamis and other natural disasters. Research past events, review predictions by scientists and learn how disaster relief can be most effective.
  1. Quantum phase transition detected on a global scale deep inside the Earth

    A multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth's mantle. Their findings will improve understanding of the Earth's interior, and help elucidate the impact of this phenomenon on tectonic events including volcanic eruptions and earthquakes.
  2. How to better identify dangerous volcanoes

    The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new study now shows that this simple rule is only partially true. Paradoxically, high water content significantly reduces the risk of explosion.
  3. Wildfires affect cave diversity underneath scorched surfaces

    The landscape at Lava Beds National Monument in northern California is typically home to sage and junipers, with unique lava caves twisting underneath the surface. But in the summers of 2020 and 2021, wildfires tore through the region, burning thousands of acres and leaving the surface charred.
  4. ‘Pet prep’ could be key to disaster survival

    Researchers have discovered most pet owners have inadequate plans for their pets if a natural disaster strikes -- but disaster response planners may be able to turn this into a positive.
  5. Evacuation during and after the 2018 Montecito debris flow

    A new study speaks to the importance of public awareness programs in keeping residents -- and emergency management offices -- informed about rare but potentially lethal natural events in their area.
  6. Low-cost, continuous seismic monitoring system to support emission reduction efforts

    Researchers have developed a continuous seismic monitoring system that could monitor multiple geothermal or carbon storage reservoirs over a relatively large area in real time. A small seismic source generates repeated 'chirps,' which can be detected by fiber-optic cables within a radius of 80 km from the source. Field experiments showed that temporal changes in monitored reservoirs were captured with high accuracy.
  7. Earth’s ‘solid’ inner core may contain both mushy and hard iron

    New research suggests that Earth's 'solid' inner core is, in fact, endowed with a range of liquid, soft, and hard structures which vary across the top 150 miles of the inner core.
  8. Wildfire bees on the brink

    The number of threatened Australian native bee species is expected to increase by nearly five times after the devastating Black Summer bushfires in 2019-20, new research has found. With 24 million hectares of Australia's land area burnt, researchers say the casualties are clear among bee fauna and other insects and invertebrates after studying 553 species (about one-third of Australia's known bee species) to assess the long-term environmental damage from the natural disaster.
  9. Seismic forensics and its importance for early warning

    The catastrophic rockslide of February 7, 2021, in India's Dhauli Ganga Valley and the subsequent flood killed at least a hundred people and destroyed two hydroelectric power plants. Researchers traced the disaster minute by minute using data from a network of seismometers. The team posits that seismic networks could be used to establish an early warning system for high mountain regions.
  10. Structural characterization offshore Newfoundland

    Geologists completed research characterizing the complex geological evolution of the Orphan Basin, offshore Newfoundland and Labrador, using an extensive database of newly available, modern 2D and 3D broadband seismic reflection data. These data allow geologists to visualize and understand the subsurface.
  11. 'Beach ball' representations calculated for US underground nuclear tests can aid monitoring

    Researchers have calculated moment tensors for 130 underground nuclear and 10 chemical test explosions that took place at the Nevada National Security test site.
  12. Limiting the impacts of technology materials for the low carbon transition

    Researchers have demonstrated how a detailed 'cradle to grave' evaluation at the outset of new metal mining explorations can greatly mitigate against negative environmental impacts.
