Tropical Cyclone GIOVANNA-12 of Saffir-Simpson Category 4 affected 13.4 million people with winds above 39mph (63 km/h) and 639 thousand people with hurricane wind strengths (74mph or 119 km/h). In addition, 23 thousand people are living in coastal areas below 5m and can therefore be affected by storm surge.

New GDACS website launched in 2012 Fri, 30 Dec 2011 00:00:00 GMT

GDACS is proud to present the new website. The various components of GDACS, i.e. alert system, coordination platform and mapping system, have harmonized their look and feel to provide a better user experience. In addition, a lot of new functionality has been added, both in the alert section and the Virtual OSOCC. We hope the new website will allow you to find and contribute information more effectively.

New cyclone storm surge models contributed in Samoa exercise Thu, 15 Dec 2011 00:00:00 GMT

â??A maximum storm surge of 1.8m is forecast for Apia, Samoa.â? This GDACS message went out to the local emergency response community and a global volunteering crowd-source community in a recent simulation exercise in Samoa. New storm surge models developed by JRC were tested in this simulation before they go live for all tropical cyclones worldwide. Of the three major hazards associated with cyclones, GDACS impact assessments now consider extreme wind and storm surge. A third one â?? extreme rainfall, which often causes landslides â?? is in development. â??Thanks for sharing the dataâ?, said a spokesman of GISCorps, a GIS volunteering community that was active in the exercise. GDACS not only distributes comprehensive messages for emergency managers, but also shares openly the data and services necessary for further analysis and the creation of rapid maps by GIS experts.

Multi hazard daily newsletter
GDACS also offers daily alerts for all disaster types monitored. Up to now, only earthquake alerts were available (apart from the RSS feeds). Since tropical cyclones, volcanoes and floods are not as 'sudden onset' as earthquakes, only a daily service is available.

See today's as an example.
GDACS alert feeds
The alerts published by the Global Disaster Alert and Coordination System can also be used in your RSS reader or on Google Earth. GDACS is using existing XML and content standards.

Legend

Based on the location and magnitude of the disasters and the local population and their vulnerability, disasters are classified in three classes:

green Green: very low likelihood of humanitarian disaster
orange Orange: potential humanitarian disaster
red Red: very high likelihood of humanitarian disaster

How to use GDACS alerts

The events listed on this page have been automatically selected by a computer program based on the earliest available information; alert levels will not be modified manually. However, if new information comes available alert levels are updated automatically. For confirmation or further information of the disaster, please refer

  • to the “coordination” section of GDACS (OCHA Virtual OSOCC and ReliefWeb),
  • to the media
  • and – most importantly – to the local disaster response authority.

GDACS does not provide authoritative information. Please do not use GDACS alerts for emergency response decision making without alternate sources of information. If you are an emergency manager, please register for GDACS coordination (Virtual OSOCC).
