The system of evacuation information issuance by local governments has been amended one after another in recent years, such as the introduction of five alert level with the revision of the "Guidelines for Evacuation Information" and the unification of conventional evacuation advisories and evacuation orders due to the revision of Basic Act on Disaster Management. These have been led by the conventional government, triggered by the heavy rains in July 2018 and the Typhoon Hagibis, which caused enormous damage in recent years and caused enormous damage due to meteorological disasters. The decision to issue evacuation information is left to each local government, and the method of issuing evacuation information differs depending on the region.

The purpose of this study is to survey the current status of the issuance of evacuation information for local governments nationwide. The issuance of evacuation information for local governments is described in the "Regional Disaster Prevention Plan" preparedby each local government, but whether or not there is a description of specific issuance standards and methods differs depending on the local government. Therefore, we conducted a questionnaire survey to about 800 local governments.

As a result, it was found that more than 70% of local governments have specific rules for issuing evacuation information for both flood disasters and sediment-related disasters. In addition, many proclamations that set specific issuance rules are decided on regional disaster prevention plans and websites, and the issuance standards of local governments that do not set specific rules standards are the water level of the rivers, disaster prevention weather information by japan Meteorological Agency and precursors. It was also found that some local governments use evacuation information transmission means in addition to existing transmission means, which have become widespread in recent years. In addition, it was found that there may be a discrepancy in the perceptions of local governments because the two words "occurrence" and "imminent" of disasters are explained about ensuring emergency safety measures. Many local governments answered that they would evaluate the unification of evacuation orders to some extent, and said that the improvement by unification was that the timing of evacuation was clearly defined and that evacuation information became easier to understand. Opinions were raised that the issues of unification were that there was a possibility that the residents would be informed and that evacuation orders would be missed, and that it was necessary to be careful inmaking decisions regarding the issuance of evacuation orders.

It was found that the local governments that the standards for issuing evacuation information for local governments issue evacuation information using disaster prevention weather information and, in some areas, the prefecture's own system. In addition, there is no answer that the local government operates its own forecasting system, and it is desirable that the forecasting, which is the standard for issuing evacuation information, is based on disaster prevention weather information.

On the other hand, the geographical and social characteristics of each local government and the cognition of precursory phenomena are likely to be excellent in the information of each local government, and from these viewpoints, it is appropriate to calculate back from the completion of evacuation. It is considered effective to issue evacuation information.
