The calculation formula for the earthquake magnitude $M$ (Richter magnitude) is $M= \lg A- \lg A_{0}$ (where $A$ is the maximum amplitude of the measured earthquake, and the constant $A_{0}$ is the amplitude of the "standard earthquake"). The seismic feeling of a 5-magnitude earthquake is already quite noticeable. On May 12th of this year, an 8-magnitude earthquake occurred in Sichuan, China. The maximum amplitude of this earthquake is \_\_\_\_\_\_ times that of a 5-magnitude earthquake (rounded to the nearest whole number).
