Claim: Mount Etna in Sicily intensified on August 8, with a new eruptive vent opening at around 2,550 meters inside the Valle del Bove, filled by pyroclastic flows and continued explosive activity.
Verdict: Partially True (50% confidence)
Explanation: According to Reuters Connect, Mount Etna entered a new paroxysmal phase with intense activity on August 8, confirming the intensified activity. Watchers.news reports that a new vent opened in the Valle del Bove, supporting the claim about the vent's location. However, no source explicitly confirms that the vent was filled by pyroclastic flows. Go-etna.com supports the continued explosive activity. The absence of confirmation regarding pyroclastic flows prevents a 'correct' verdict.
