We started to provide RSS (RDF Site Summary / Rich Site Summary / Really Simple Syndication) 1.0 Feed.
To display RSS feeds on your web pages, another option is to use a web widget (blog parts) Typhoon Visual Report. This widget is only available in Japanese, however.
The latest information is also distributed from Twitter.
Here is the link collection of RSS related to meteorological, geographic, and earth science information. This site uses RSS for the notification of the birth and the current status of a typhoon, and it seems that syndication services can be used for the notification of other natural phenomena.
Recent earthquake information distributed from U.S. Geological Survey.
RSS Feeds distributed from National Hurricane Center in the USA. English and Spanish for Atlantic basin and English for Eastern Pacific basin.
