The Global Disaster Alert and Coordination System
provides near real-time alerts about natural disasters around the world
and tools to facilitate response coordination, including media monitoring, map catalogues and Virtual On-Site
Operations Coordination Centre.
Events in this list are picked up from multiple
sources and automatically analyzed by a computer program to determine
the likelihood of humanitarian intervention. News, damage maps and humanitarian
situation reports are collected automatically from over 1000 on-line sources.
After the DNS switch yesterday, some services were not working properly. The DNS propagation is quite slow (24h) so what you see depends on when you last visited GDACS. Some users see the new system (with potential bugs) and some - like us - see the old system. Based on your feedback, we've addressed the following issues:
Configured MIME type for KML and KMZ files. Absence of this MIME type in IIS prevented this content to be served.
Fixed issue with GDACS Earthquake Push system. A conflict between ASP and .Net and different versions of the MySQL connector (32 and 64 bit) caused this application to fail. This affected all Tsunami Alerting Tool installations.
Configuration of IIS for alternative DNS names, including new.gdacs.org and gdacs.org. These were redirected to the new server, but not assigned to the right website.
Cross reference issue between old and new site for event list. The event list on the hompage was composed using an RSS file of the old system. All RSS links now point to the new system.

The JRC will shortly upgrade hardware and software underlying the GDACS monitoring, alert and public web system. User registration and changes to the alert profile will be unavailable for a short time, but other changes should be transparent. The main changes are:
Complete overhaul of the Earthquake and Tsunami system for better performance and with new alert models for tsunamis, support for national sub-systems and for different alert scales
Upgrade of the geospatial database system from ArcGIS Server 9.3 to 10, with new features for better maps
Migration of hardware from JRC corporate web zone to a dedicated subnet with more flexibility for scaling and deploying new beta products, and reducing the servers from 15 to 8 more powerful ones in a new architecture.
The new system can be previewed on �http://w2.gdacs.org. Please let us know if you notice bugs with services you're using, in particular for syndicated feeds. After the switch (which will be announced in a further message), the old system will be available on �http://w1.gdacs.org. Please don't hesitate to �contact us �for further information.

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
Based on the location and magnitude of the disasters and the local population
and their vulnerability, disasters are classified in three classes:
low likelihood of humanitarian disaster
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).
