Description

<p>To clarify the mechanism of how a crowd accident occurs, phenomena in a high-density crowd accumulation were analyzed based on videos of extra-high-density crowd accumulation, crowd disaster investigation committee's reports and observation of high-density crowd phenomena of large-scale events. When the crowd density reaches 8 persons per square meter or so, crowd shock waves of 20 cm to 60 cm will occur due to the fluctuating density and pressure distribution in the crowd. When the density reaches 10 persons per square meter or more, people feel a surge of panic because of a fear of being crushed, possibility of crowd disaster will be higher with complicated critical crowd shock waves.</p>
