Scientific Observations Will Tell Us What Comes Next

Officials at Involcan have been hard at work measuring all they can about the volcanic activity. On Sunday before the explosion, seismologists recorded tremors measuring up to 4.2 in magnitude. And early temperature measurements of the lava showed that it was 1,967 degrees Fahrenheit (1,075 Celsius), hot enough to incinerate anything in its path.
The big question is how long the eruption will go on for. And on that front, it’s not clear. “It could suddenly stop, or persist for days, weeks or even months,” Robin George Andrews, volcanologist and writer, said on Twitter. “If so, expect a lot of lava flowing across the island’s south.”
