"Wiping off the map" is a phrase that describes a severe action of erasing or destroying something entirely. If you are looking for synonyms for this intense expression, you might consider words such as annihilating, obliterating, eradicating, decimating, or demolishing. Each of these words not only implies a sense of total destruction or removal of something but also suggests a permanent state of loss or absence. It's crucial to note, however, that the words you choose to use will largely depend on the context of your sentence or paragraph and the nuances you want to convey.
