Yeah, it pretty much blew out that whole section of coastline, that big hole is called a "caldera". It's still active btw, you can go and check it out if you want. Look for Solfatara di Pozzuoli.

You can also look at the Greek island of Santorini, where the whole western and central part of the island was blown off during the bronze age iirc. Historians speculate the eruption, earthquake and tsunamis caused by the event could have partially influenced the collapse of the Minoan civilization, the rise of the Mycenaeans, turmoil in Egypt and possibly even the fall of the Chinese empire due to a global winter. Crazy stuff
