Early warning systems are widely considered as one of the more important aspects to reduce the impacts and consequences that hazardous natural events pose to societies. Similar to the other terms related to disaster risk reduction, this concept has evolved over time to eventually result in a comprehensive framework, that includes features from the upstream phase, such as detection and forecasting tools and models, to the downstream phase that considers a people-centred approach.

Based on this holistic conceptual framework, this paper attempts to assess the degree of adequacy and integration of early warning systems with reference to international standards using a multi-hazard perspective. The study is focused on the following Asian countries: the Maldives, Sri Lanka, Myanmar and the Philippines.

Results obtained provide an inventory of existing approaches and systems, showing common backgrounds and consistencies in their conceptualisation. In addition, the findings of this study highlight the strengths and weaknesses of Multi-Hazard Early Warning Systems in each country considering their technical, legal, and socio-economic complexities. These findings are intended to support target countries to improve the availability and effectiveness of their warning systems.

预警系统被广泛认为是减少危险自然事件对社会造成的影响和后果的更重要方面之一。与其他与减少灾害风险相关的术语类似，该概念随着时间的推移不断发展，最终形成了一个综合框架，其中包括从上游阶段（如检测和预测工具和模型）到考虑人员的下游阶段的功能。中心的方法。

基于这种整体概念框架，本文尝试使用多灾种视角，参照国际标准评估预警系统的充分性和整合程度。该研究的重点是以下亚洲国家：马尔代夫，斯里兰卡，缅甸和菲律宾。

获得的结果提供了现有方法和系统的清单，显示了它们在概念上的共同背景和一致性。此外，本研究的结果突出了每个国家的多种危害预警系统的优缺点，考虑到它们的技术，法律和社会经济复杂性。这些调查结果旨在支持目标国家提高其预警系统的可用性和有效性。
