And since a multihazard system will be activated more regularly it is likely to be better maintained and more readily available for hazards such as tsunamis that occur infrequently. Such integrated systems may also help the public better understand the range of risks they face and the need to prepare and to respond to warnings. For example, many Asia-Pacific countries have already set up warning systems that are common for most hydrometeorological hazards. However, it can be difficult to combine these systems with those for geophysical hazards which are often managed by other ministries.
