In addition, the source database used is Scopus is used with the help of visualization from VosViewer, Bibliometrix, Rstudio, and Ms-Excel methods. The aim of the report is to describe the relationship and correlation between the TEWS field, the individual writer, and the country. In addition, reported in this study is Lotka's Law and Bradford's Law contribution from some articles, authors, and countries. Additionally, the present study discusses the niche, motor, emerging or declining, and basic themes of TEWS. It is expected that this study can be used as a springboard for researchers before conducting investigations directly in the field. [ABSTRACT FROM AUTHOR] |
