New dome in La Soufriere blown away

KINGSTOWN – The new dome that was forming in the crater of La Soufriere for months was blown off in the explosive eruptions, sending at least 13 million cubic metres of material into the atmosphere.

Volcanologist Professor Richard Robertson, who is leading the team of scientists working together to monitor La Soufriere, indicated that from a satellite image obtained, “where the material is coming out, where the dome was coming out, where it originally came out; it now has nothing there. It has an opening and that is where material is now coming out and that’s going up in the air.

“It seems that a substantial amount of the 2021 dome has gone, it’s been destroyed. It seems that all that black 915 [ft] length piece of bits of rock, all that 13 million cubic metres of material has mainly been destroyed in the activity that we’ve had so far.”

“It doesn’t appear that it has done very much to the 1979 dome so far, but it’s one satellite imagery, it’s not clear what it actually shows, but certainly there is a hole now; a proper vent from which material is being ejected,” he further stated on NBC radio yesterday morning.

There were three explosive eruptions Friday posted on the University of the West Indies Seismic Research Centre’s page, and continuous ash venting.

The scientist said that anyone near the volcano would have heard continuous rumbling throughout Friday night, which only had a brief reprieve at 2:30/3am, and the mountain continued energetic venting.

Explaining this, Robertson informed, “if you think of a very powerful hose, with different pieces of rock in it and then you’re trying to force that through a pipe it could make a sound. It’s the sound of the rock breaking up, of the sound of the conduit itself vibrating, its acoustics, that’s what they’re hearing.”
