EMSC has found that the speed in which people look for information is not dependent on location and has successfully detected earthquakes all over the globe. Indeed, the EMSC website gets 1.5 to 2 million visits per month from 241 countries. The following map (Figure 1 shown in original source) demonstrates that whenever an earthquake occurs in a populated area, EMSC can collect testimonies. This holds true even for areas which are not traditionally considered to have good internet access. It also works in regions where earthquakes are rare and the pre-existing visibility of the EMSC is inexistent.
