Abstract

The morphodynamics of a local thesaurus of communications within the Internet community responded to the manifestation of both seismic and volcanic activities during the Sakurajima volcanic eruption of November 14, 2018, on Japan’s southern island of Kyushu and the preceding strong earthquake of November 4, 2018, in the vicinity of the Island of Hokkaido. An ontological model of seismic hazard precursors and estimates (obtained using Internet search engines) of the frequency of semantic characteristics of a seismic hazard were used for form a local thesaurus. The prospects for using information precursors and Internet resources in monitoring both seismic and volcanic risks are discussed.

Keywords

Volcano, eruption, seismic hazard, precursors, thesaurus, search engines, Internet, society.
