Climate change could trigger more landslides in High Mountain Asia

More frequent and intense rainfall events due to climate change could cause more landslides in the High Mountain Asia region of China, Tibet and Nepal, according to the first quantitative study of the link between precipitation and landslides in the region.

Survey reveals low awareness of volcanic hazards in Australia

On December 9, several Australians were among the dozens of tourists who were killed, injured, or went missing after a deadly eruption on Whakaari/White Island in New Zealand. Whakaari/White Island has seen more volcanic activity in the past 10 years than neighboring Australia has seen for 5,000, but according to volcanologists, the country is not free from the risks of a potential eruption. And according to a new survey, Australian citizens are mostly unaware of their country’s potential volcanic hazards.

One of Europe’s worst famines likely caused by devastating floods

Europe’s Great Famine of 1315–1317 is considered one of the worst population collapses in the continent’s history. Historical records tell of unrelenting rain accompanied by mass crop failure…Now, new research using tree ring records confirms the historical data, showing the years of the Great Famine were some of Europe’s wettest.

Property values plummeted and stayed down after Hurricane Ike

Texas homes that took the biggest hit in value after 2008’s Hurricane Ike were, surprisingly, not those within historic flood zones, new research finds. Instead, they were homes just outside these zones, where damage affected whole neighborhoods, driving property value down for years, according to a team of researchers from the University of North Carolina, Chapel Hill who presented the findings this week at AGU’s Fall Meeting 2019 in San Francisco.

Geoscientists develop technology to improve forecasting of earthquakes, tsunamis

University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes in the Earth’s seafloor that are often a precursor to deadly natural hazards, like earthquakes, volcanoes and tsunamis.

Seemingly dormant geologic fault damaged famous Roman buildings 1,500 years ago

A geologic fault system in central Italy that produced a deadly earthquake in 2016 is also responsible for a fifth-century earthquake that damaged many Roman monuments, including the Colosseum, according to new research. The Mount Vettore fault system, which winds through Italy’s Apennine Mountains, ruptured in the middle of the night on August 24, 2016. The magnitude 6.2 earthquake it generated killed nearly 300 people and destroyed several villages in the surrounding region. The fault ruptured again in October 2016, producing two more earthquakes with magnitudes greater than 6.

Fort McMurray homes have normal levels of indoor toxic substances following wildfire, new study reveals

Researchers have examined dust from homes in Fort McMurray in Canada for evidence of harmful toxins left in the aftermath of the devastating 2016 wildfire. Their study reveals normal levels of contaminants that are comparable to homes across Canada, and so far, no evidence of long-term health risks from fire-ash exposure in residents’ homes

Barrier island sand dunes recover at different rates after hurricanes

Sand dunes on coastal barrier islands buffer the U.S. Atlantic and Gulf coasts from oncoming hurricanes. Every year, millions of public and private dollars fund the restoration of these barrier islands, but managers often focus on the recovery of smaller sand dunes and aim at making them bigger, for better storm protection. But new research presented at the 2018 AGU Fall Meeting last month finds sand dunes on these barrier islands don’t all recover at the same rate. Small dunes go back to becoming small dunes; large dunes recover to be large dunes; and they don’t typically grow larger than they were before the storm struck.

Who is vulnerable to the impacts of tropical cyclones and why?

Tropical cyclones, and the torrential rains and strong winds these storms bring along with them, threaten coastal communities around the world and are expected to increase in intensity due to climate change. Whether or not a natural hazard, such as a tropical cyclone, becomes a natural disaster depends on whether the hazard overwhelms existing human infrastructure in a particular country or region. But when does a natural disaster result in fatalities?
