• EarthquakesA Step Closer to Being Able to Forecast Earthquakes

    Scientists identify specific conditions that cause tectonic plates to slowly creep underneath one another rather than generate potentially catastrophic earthquakes. This could potentially contribute to solving one of the greatest challenges that faces seismologists, which is to be able to forecast earthquakes with enough precision to save lives and reduce the economic damage that is caused.

  • Seismic warningsSeparating Industrial Noise from Natural Seismic Signals

    For the first time, seismologists can characterize signals as a result of some industrial human activity on a continent-wide scale using cloud computing. A transformative, cloud-computing approach to analyzing data helps researchers better understand seismic activity.

  • VolcanoesMount St. Helens’ 1980 Eruption Changed Volcanology

    If scientists armed with today’s monitoring tools and knowledge could step back in time to the two months before 18 May 1980, they would have been able to better forecast the forthcoming devastating eruption.

  • EarthquakesPreparing for the Big One: Oregon to Fund ShakeAlert

    With a vision for preparing the state for a large Cascadia earthquake, Oregon Gov. Kate Brown announced on Monday a resiliency agenda for the upcoming legislative session that would include $7.5 million in funding to the University of Oregon to build out the ShakeAlert earthquake early warning system.

  • VolcanosCould the New Zealand Volcanic Eruption Have Benn Predicted?

    The agency that monitors geological activity in New Zealand, GeoNet, had issued warnings that a volcano off the country’s North Island was showing signs of “moderate volcanic unrest” but it might not have been possible to predict that it would suddenly erupt on Monday, according to geologists.

  • New Zealand volcanoNo More Survivors Expected after New Zealand Volcano Erupts

    Five people were confirmed dead and eighteen others injured, with many more missing, after a volcano erupted on Monday afternoon while dozens of cruise ship passengers were exploring White Island, a small, picturesque, uninhabited island of the coast of New Zealand.

  • New Zealand volcanoWhy White Island Erupted and Why There Was No Warning

    By Shane Cronin

    White Island is one of several volcanoes in New Zealand that can produce sudden explosive eruptions at any time. In this case, magma is shallow, and the heat and gases affect surface and ground water to form vigorous hydrothermal systems. In these, water is trapped in pores of rocks in a super-heated state. Any external process, such as an earthquake, gas input from below, or even a change in the lake water level can tip this delicate balance and release the pressure on the hot and trapped water. The resulting steam-driven eruption, also called a hydrothermal or phreatic eruption, can happen suddenly and with little to no warning.

  • EarthquakesUnderwater Telecom Cables to Be Used as Seismic Detection Network

    About 70 percent of Earth’s surface lies under the sea, which means that, until now, most of the Earth’s surface had been largely without early-warning seismic detection stations. Scientists say that fiber-optic cables that constitute a global undersea telecommunications network could one day help in studying offshore earthquakes.

  • Perspective: Conspiracy theoryEarthquake Conspiracy Theorists Are Wreaking Havoc During Emergencies

    Scientists have been trying hard to be able to predict earthquakes, because accurately predicting an earthquake would save lives, decrease property damage, and allow people to have some measure of control over one of nature’s most frightening and unpredictable events. Scientific predictions of the location and time of specific tremors are modest in scope – which have created an opening for earthquake conspiracy theorists who “claim that they have discovered the key to accurate quake prediction, as well as the hidden secrets behind why these tremors happen,” Anna Merlan writes.

  • FloodsWhy Flooding Is Still So Difficult to Predict and Prepare for

    By Hannah Cloke

    Given the huge costs to people and property when it floods, it’s a reasonable question to ask why, in one of the richest countries in the world, more cannot be done to prevent flooding. And if not prevent it, to know more precisely when and where it will hit.

  • EarthquakesFirst Statewide Testing of ShakeAlert in the United States

    Earlier this month, the U.S. Geological Survey and the State of California pressed the “go” button to allow the first-ever statewide public testing of the California Early Earthquake Warning System, which is powered by USGS’s earthquake early warning alerts, called ShakeAlerts. Alerts will be delivered by two independent methods, first over the federal Wireless Emergency Alert (WEA) system and second through the University of California Berkeley’s MyShake smartphone app.

    Researchers are using high-performance computing systems to better predict how structures will respond to an earthquake along one of the Bay Area’s most dangerous faults.

  • PerspectiveTrump Pushed Staff to Deal with NOAA Tweet that Contradicted His Inaccurate Alabama Hurricane Claim, Officials Say

    President Trump told his staff that the nation’s leading weather forecasting agency – the National Weather Service (NWS), which is part of the National Oceanic and Atmospheric Administration (NOAA) — needed to take back a statement NWS made on 1 September, correcting a tweet the president had sent wrongly claiming that Hurricane Dorian threatened Alabama. Trump’s demand was conveyed by White House acting chief of staff Mick Mulvaney to Commerce Secretary Wilbur Ross (NOAA is part of the Commerce Department). Ross then threatened to fire the acting NOAA administrator Neil Jacobs unless NOAA issued a statement backing Trump’s false claim about Alabama, and admonishing the NWS’s scientists for correcting Trump’s wrong and misleading claim. Jacobs issued the statement Trump demanded in an unsigned press release on 6 September (NOAA chief scientist has now launched an investigation of Jacobs’s misleading press release, which was issued without consulting any scientists or meteorologists). Trump, talking with reporters on Wednesday, then falsely asserted that he did not direct NOAA to issue such a statement. “No, I never did that,” he said. “I never did that. It’s a hoax by the media. That’s just fake news.”

  • Perspective: Phone alertsBritain Plans Mass Mobile Phone Alerts to Protect Public from Terrorism, Major Floods and Nuclear Attack

    Britain is planning to introduce US-style mass mobile phone alerts to protect the public against terrorism, major floods and nuclear attack. Supporters of so-called ‘cell broadcasting’ claim the message alerts could have saved lives during major incidents including the London Bridge terrorist attack and Grenfell Tower fire. Senior figures have raised concerns, however, that the messages could be hijacked by hackers or malicious foreign powers to induce mass panic.
