The reaction of Internet Users to the Seismic Hazard

A prototype of a generalized portrait of Internet community activity for three major earthquakes that occurred in different regions of the Earth: Mexico, Japan, and Afghanistan is discussed. Internet community activity is a response to the second alarm system. A model of the response of Internet community activity to earthquake precursors is proposed. To detect "informational" harbingers of seismic danger, sets of query words semantically related to geophysical harbingers were used. The search for the keyword repeatability was carried out using Internet search engines. The geographical binding of requests was taken into account. No effects of Internet community activity were observed in earthquake-prone regions. The analysis of earthquake information precursors was carried out according to the calculated spectra and amplitude diagrams of variations in the query word repeatability. Before the earthquakes in the earthquake-prone region, Internet community activity increased with statistically significant harbinger signals. The presented results are useful for use in artificial intelligence technologies.
