At Tel Miqne there is no evidence yet for a major destruction of the Canaanite city (see Trude Dothan, “Ekron of the Philistines, Part I: Where They Came From, How They Settled Down and the Place They Worshiped In,” BAR 16:01). Bronze Age Ashdod was largely destroyed (though not in all areas). As for Ashkelon, it is better to await the results of the recent excavations to see if they confirm the preliminary conclusions of Phythian-Adams (see Lawrence E. Stager, “When Canaanites and Philistines Ruled Ashkelon,” BAR 17:02).
