Derrumba

Derrumba is the third-person singular present indicative form of the Spanish verb derrumbar, meaning to bring down or collapse something or to demolish. It is used with a direct object to describe an active collapse caused by a force or agent. Example: "El sismo derrumba la casa" (The earthquake collapses the house). The verb is transitive and can express both natural-induced collapse and deliberate demolition, depending on context.

As a noun, derrumba is less standard. The common noun for a collapse or landslide is derrumbo or derrumbe. Some regional or colloquial usage may render derrumba as a noun, but it is generally considered nonstandard or dialectal in mainstream Spanish dictionaries. In professional or formal writing, derrumbo/derrumbe is preferred to refer to the event, whereas derrumba is reserved for the verbal form.
