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. Puzzling features deep in Earth's interior illuminated

    New research examines an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface.
  2. Validation brings new predictive capability to global megafire smoke impacts

    New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures. As huge wildfires become more common under climate change, increased attention has focused on the intensity and duration of their emissions, which rival those of some volcano eruptions.
  3. Remote sensing research improves hurricane response

    Researchers are investigating better ways to predict where road-clogging debris will be most severe after tropical cyclones.
  4. Hunga volcano eruption provides an explosion of data

    The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami.
  5. New research could provide earlier warning of tsunamis

    A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis.
  6. Ice-capped volcanoes slower to erupt, study finds

    The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- located under about 1 kilometer of glacial ice -- has yet to erupt again. Using the Westdahl Peak volcano as inspiration, a new volcanic modeling study examined how glaciers affect the stability and short-term eruption cycles of high-latitude volcanic systems -- some of which exist along major air transportation routes.
  7. Lake Erie quakes triggered by shifting water levels? Study finds no smoking gun, urges further research

    In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.
  8. Failed eruptions are at the origin of copper deposits

    Copper is one of the most widely used metals on the planet today due to its electrical and thermal conduction properties. The greatest natural resources of this metal are the so-called 'porphyry' deposits that come from magmas deep in the Earth. In recent research, scientists demonstrate that these deposits are largely produced by mechanisms similar to those causing large volcanic eruptions. At a time when current copper resources are dwindling and this metal plays a key role in the energy transition, this discovery opens up new avenues for the development of tools to find new deposits.
  9. Major 2020 Alaska quake triggered neighboring 2021 temblor

    A study of two powerful earthquakes in adjacent areas off the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade along the fault.
  10. Researchers home in on Thera volcano eruption date

    Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years -- Aniakchak II. In the process, they narrowed down potential dates for the Thera volcano eruption.
  11. Space-based system using GPS satellites could warn of incoming tsunamis

    A new method for detecting tsunamis using existing GPS satellites orbiting Earth could serve as an effective warning system for countries worldwide, according to a new study.
  12. New climate modeling predicts increasing occurrences of flash flooding across most of the U.S.

    A research team has created simulations from coupled climate and hydrologic models that demonstrate widespread increases in the occurrences of flash flooding events across most of the United States.
