National Earthquake Data Center
Short description
The National Earthquake Data Center (NEDC) is the central platform for sharing earthquake-related scientific data in China. It is part of the Earthquake Science Data Sharing Platform, which consists of a national center and multiple specialized sub-centers focusing on different geophysical observation systems.
The repository integrates extensive datasets related to seismic monitoring, crustal deformation, geomagnetism, gravity observations, and earthquake disaster information. Currently, the platform manages over 260 TB of scientific data across 54 databases and more than 100 datasets.

Video tutorial
The repository provides illustrated documentation explaining how to access earthquake datasets, including the procedures for account creation, dataset search, and data request submission.
Access notes
Users must create an account before accessing the platform. Downloading datasets requires approval and may involve additional verification steps such as linking a Chinese phone number or submitting identification information.
The platform interface is available only in Chinese, which can make navigation more difficult for international researchers. Additionally, metadata does not clearly indicate the access level required to download specific datasets.
Repository overview
The National Earthquake Data Center integrates data from multiple specialized sub-centers focusing on different aspects of earthquake science, including geomagnetism, strong-motion observation, crustal deformation, gravity measurements, geoelectric monitoring, and underground fluid observations.
The repository contains large-scale observational datasets as well as data from surveys, scientific projects, and disaster monitoring systems. These resources support earthquake research, hazard assessment, and disaster prevention and mitigation.
