Is anyone looking into atypical pyroclastic flow/surge? Like what happened in Martinique that killed 30k people with only 3 survivors?

Was there a vent that they knew about and didn’t tell anyone?

It wouldn’t be hard to believe that the board of tourism and the government would want to hide this information. I mean, who’d want to go on vacation with a possibility of being vaporized.

It would go a long way in explaining why it went out into the water and why there have been some reporting that they were getting pelted with rocks.
