• Perfect continuous tense sentences discuss the aftermath of an act that has occurred or has been committed in the past and is continuing currently.
• A present perfect tense can be formed with an auxiliary verb and the present tense of the verb word. The verb used will be a gerund, i.e.; a verb word ending with 'ing'.
• Therefore, the perfect continuous tense of 'create' is 'has been creating' or 'have been creating'.
• As the sentence is singular, has only one volcano the appropriate word is 'has been creating'.
