National Research Institute for Earth Science and Disaster Resilience (NIED) integrated the land observation networks established since the 1995 Kobe earthquake with the seafloor observation networks established since the 2011 Tohoku earthquake and tsunami as MOWLAS (Monitoring of Waves on Land and Seafloor) in November 2017. The purpose of MOWLAS is to provide comprehensive, accurate, and rapid observation and monitoring of earthquake, tsunami, and volcano events throughout Japan and its offshore areas. MOWLAS data are widely utilized for long-term earthquake forecasting, the monitoring of current seismic activity, seismic and tsunami hazard assessments, earthquake early warning, tsunami warning, and earthquake engineering, as well as earthquake science. Ocean bottom observations provide an extension of observations to areas where no people are living and have the advantage of increasing lead time of earthquake early warning and tsunami warning. The application of recent technology advancements to real-time observations as well as the processing of MOWLAS data has contributed to the direct disaster mitigation of ongoing earthquakes. These observations are fundamental for both science and disaster resilience, and thus it is necessary to continue ceaseless operation and maintenance.

MOWLAS：NIED 地震、海啸和火山观测网络

国立地球科学与防灾研究所 (NIED) 于 2017 年 11 月将自 1995 年神户地震以来建立的陆地观测网络与自 2011 年东北地震和海啸以来建立的海底观测网络整合为 MOWLAS（陆地和海底波浪监测） . MOWLAS 的目的是对日本及其近海地区的地震、海啸和火山事件提供全面、准确、快速的观测和监测。MOWLAS 数据广泛用于长期地震预报、当前地震活动监测、地震和海啸危害评估、地震预警、海啸预警和地震工程以及地震科学。海底观测将观测范围扩展到无人居住的地区，并具有增加地震预警和海啸预警提前期的优势。将最新技术进步应用于实时观测以及 MOWLAS 数据的处理有助于直接减轻正在发生的地震的灾害。这些观测对于科学和灾害恢复力都至关重要，因此有必要继续不断地运行和维护。
