The lava dome had been growing quietly since December. For more than three months, residents of northern Saint Vincent watched the readings climb: 90 meters high by mid-January, then 618 meters long and still expanding by February.

By 8:41 the next morning, La Soufriere blew its top in an explosive eruption that sent an ash column streaming eastward across the Atlantic and forced 16,000 people from their homes -- in the middle of a global pandemic.
