Relief Web is a valuable data and information source, freely available on the internet. Relief Web hosts reports written by a number of humanitarian agencies following disasters, including those with a geohazard context. You can search by country and disaster - and the site hosts reports, maps and at times links to available aerial photographs. there are also jobs posted.
The site has proved to be helpful for gathering information on major humanitrian situations - but also smaller situations, which are not in the media so much.
