How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media
Earth's Future, Volume 13, Issue 4, April 2025.Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.
