Hello regalsoldier,
Pleased to meet you! That is an excellent question! - The data needed for this app is gathered from various geological and space agencies that share this information freely. However the Suspicious Observers application and approach to weather and seismic activity is truly cutting edge, and their predictions are always far ahead of the mainstream agencies such as USGS.

keep well :D

I believe real hard work behind this app to develop
Thank you i found this helpful .
