מִקּ֣וֹל נִפְלָ֔ם רָעֲשָׁ֖ה הָאָ֑רֶץ צְעָקָ֕ה בְּיַם־ס֖וּף נִשְׁמַ֥ע קוֹלָֽהּ׃
Del estruendo de la caída de ellos la tierra tembló, y el grito de su voz se oyó en el mar Bermejo.
Chizkuni
נסו לקולם, “they fled when hearing their sounds”. This is a reference to the outcries of the people being swallowed by the earth. We know of a parallel in Jeremiah 49,21: מקול נפלם רעשה כל הארץ, “at the sound of their downfall the whole earth will shake.”
Rashbam
נסו לקולם, when they cried out at the time when they fell into the bowels of the earth. Compare Jeremiah 49,21 לקול נפלם רעשה ארץ, “the earth itself shook when it heard the sound of their downfall.”
