En Masse

After Mexico’s victory over Germany in last Sunday’s World Cup match, the Institute of Geologic and Atmospheric Investigations in Mexico City reported a small artificial earthquake possibly caused by the mass jumping of tens of thousands of celebrants. Write a short story in which the concurrent actions of a large population of people causes some sort of noticeable geological event. What is the cause of the hoopla, and does it end up causing a ripple effect of far-reaching consequences? Perhaps your story will have a sci-fi slant with a futuristic setting or incorporate humor commenting on current environmental concerns.
