Future tsunamis possible in the Red Sea's Gulf of Elat-Aqaba

Wed, 12/06/2019 - 19:14
Researchers who took a closer look at a 1995 tsunami in the Gulf of Elat-Aqaba, at the northeastern tip of the Red Sea, say that the gulf's surrounding countries should prepare for future tsunami hazards in the economically developing vital region.

Lake sediment records reveal recent floods in NW England (UK) unprecedented

Tue, 21/05/2019 - 17:46
A new study of UK lake sediment records stretching back over several centuries has found that the floods that hit Northern England in 2009 and 2015 ('Storm Desmond'),were the largest in 600 years, pointing to the impact of climate changes on the frequency and magnitude of these extreme events.

Ritter Island gives new insights into the dynamics of volcanic landslides

Thu, 16/05/2019 - 16:46
The flanks of many island volcanoes slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists now show that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse.

Quick reconnaissance after 2018 Anchorage quake reveals signs of ground failure

Fri, 26/04/2019 - 18:00
A day after the Nov. 30, 2018, magnitude 7 earthquake in Anchorage, Alaska, US Geological Survey scientists had taken to the skies. The researchers were surveying the region from a helicopter, looking for signs of ground failure from landslides to liquefaction.

Minerals in mountain rivers tell the story of landslide activity upstream

Wed, 24/04/2019 - 20:35
Scientists have come up with a new way of analyzing sand in mountain rivers to determine the activity of landslides upstream, which has important implications for understanding natural hazards in mountainous regions.

Salish seafloor mapping identifies earthquake and tsunami risks

Wed, 24/04/2019 - 17:51
The central Salish Sea of the Pacific Northwest is bounded by two active fault zones that could trigger rockfalls and slumps of sediment that might lead to tsunamis.

Hurricane Harvey provides lessons learned for flood resiliency plans

Wed, 10/04/2019 - 14:59
Scientists used satellite data to map the Houston-Galveston area impacted by Hurricane Harvey to understand why the flooding was so severe and widespread.

Farming for natural profits in China

Mon, 01/04/2019 - 22:14
Expanding monoculture threatens valuable services from land, such as flood control, water purification and climate stabilization. A new approach promises to protect these benefits, while improving biodiversity and human livelihoods in rural areas around the world.
