Crowd surges during Durga Puja are often triggered by sudden events, such as heavy rainfall, which can lead to people rushing to seek shelter in pandals. Narrow lanes and inadequate infrastructure can exacerbate the situation, making it difficult for organisers and civic volunteers to manage the influx of visitors. Such conditions can lead to stampedes and structural failures, as seen in the tragic incident at the Chorbagan Sarbojanin pandal.
