  • Lamont to Develop New Earthquake and Tsunami Warning System
    January 17, 2017

    Natural disasters have caused the deaths of hundreds of thousands of people worldwide with associated costs of hundreds of billions of dollars in property damage. Providing timely warnings of damaging ground-shaking from earthquakes and the imminent arrival of tsunamis is an ongoing challenge. Networks of instruments developed in recent years by researchers at the Lamont-Doherty Earth Observatory and elsewhere have improved our ability to provide those predictions for vulnerable populations. A new pilot program led by Lamont aims to make those warnings earlier and more accurate.

  • Signs of Ancient Megatsunami Could Portend Modern Hazard
    October 02, 2015

    Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden giant collapses present a realistic hazard today around volcanic islands, or even along more distant continental coasts. The study appears today in the journal Science Advances.

  • Japan's Natural Hazards

    The largest recorded earthquake in Japan's history has triggered a series of events that have killed thousands, crushed and submerged cities, and left a financial toll from which it will take years for an already struggling economy to recover.

  • Lamont Scientists Present Findings on Hidden Dangers of Climate Change, Natural Hazards

    Dec 10, 2007--Scientists from Columbia University’s Lamont-Doherty Earth Observatory will report this week on vital topics including new evidence of the effects of climate change; technologies to confront it; studies of eastern U.S. earthquake risk; and previously unseen inner workings of the deep polar ice caps.  The reports will be presented at the fall 2007 American Geophysical Union (AGU), the largest earth-sciences gathering in the world, Dec. 10-14 in San Francisco.

  • LDEO Marine Seismic Research Contributes to Global Tsunami Detection and Warning System
    January 24, 2005

    Marine seismic research will play an invaluable role in providing the same level of warning currently in the Pacific Ocean to the Indian and Atlantic Oceans, including the Caribbean Sea and Gulf of Mexico. In January 2005 the Bush Administration committed $37.5 million to expand the current global tsunami detection and warning systems.
