GIS and mapping

A new study goes deep into the Gulf of Alaska to examine the sixth-largest underwater landslide and investigate why a similar event hasn’t happened since.

The study aims to identify and characterize 'hotspots' of flood risk, accounting for spatial variation in social vulnerability, to provide improved insights into the geography of risk and enhance disaster risk planning and response efforts.

What if the place you were looking for could not be found on any map? Not because it's hidden, but because it was never mapped. And what if people in need were living in unmapped places?

The unacknowledged reason why there is a lack of flood risk mapping in Canada is because such maps generally face public resistance. Indeed, it is not uncommon in Canada to see flood or wetland mapping withdrawn or modified because of public pressure.

The U.S. Geological Survey (USGS) recently invested in a geologic mapping project throughout Puerto Rico using airborne hyperspectral imaging to chart surface geologies essential to natural hazards resilience.

This observation points towards land cover changes being a critical factor in landscape dynamics, stressing the human pressure as a discriminant cause/effect term for natural vs. human-induced landslide fatalities.

The objective of this report is to show how the European Crisis Management Laboratory Mapping Team at the Joint Research Centre plays a key role in delineating all the components of disaster events, with its daily reports and on-demand products.

The GEUS report indicates that dumping of soil at the top of the slope triggered two large earthflows, driving instability across the site.
