The importance of the presented work lies within the practical applicability of the proposed system for timely delivery of early warning and notification messages in cases of natural disasters or industrial accidents.</jats:p></jats:abstract><publication_date media_type="online"><month>6</month><day>6</day><year>2025</year></publication_date><publication_date media_type="print"><month>6</month><day>6</day><year>2025</year></publication_date><pages><first_page>62</first_page><last_page>70</last_page></pages><publisher_item><item_number item_number_type="article_number">7</item_number></publisher_item><ai:program xmlns:ai="http://www.crossref.org/AccessIndicators.xsd" name="AccessIndicators"><ai:free_to_read start_date="2025-06-06"/><ai:license_ref applies_to="am" start_date="2025-06-06">https://npublications.com/journals/educationinformation/2025/a162008-008(2025).pdf</ai:license_ref></ai:program><archive_locations><archive name="Portico"/></archive_locations><doi_data><doi>10.46300/9109.2025.19.7</doi><resource>https://npublications.com/journals/educationinformation/2025/a162008-008(2025).pdf</resource></doi_data><citation_list><citation key="ref0"><doi>10.1007/s11069-023-05926-x</doi><unstructured_citation>A.
