According to the state news agency Xinhua, the collapse occurred due to construction workers illegally placing perlite, a form of volcanic glass, on the building’s roof. The presence of perlite, combined with heavy rainfall, caused it to expand and increase in weight, ultimately leading to the roof’s catastrophic failure.
