Тестирование метода на известных точных решениях для волновых фронтов цунами показало более качественную аппроксимацию волновых фронтов по сравнению с существующим сеточным методом, разработанным автором ранее.</p></abstract><trans-abstract xml:lang="en"><p>The new method for the tsunami travel times calculation to the nodes of rectangular grid was developed and tested. The algorithm is based on constructing of the wave front segment inside the grid cell using tsunami arrival times to the cell corners. Testing the method proposed shows the better quality of the wave-front line approximation as compared to the existing method developed by the author earlier.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>волна цунами</kwd><kwd>кинематика волнового фронта</kwd><kwd>цифровая сеточная батиметрия</kwd><kwd>времена вступления цунами</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tsunami wave</kwd><kwd>kinematics of the wave front</kwd><kwd>digital gridded bathymetry</kwd><kwd>tsunami travel times</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках Государственной бюджетной программы с ИВММГ СО РАН (№ 0315-2019-0005)</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This work was carried out under state contract with ICMMG SB RAS (no. 0315-2019-0005)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shokin Yu.
