On­ly a few small earth­quakes have been record­ed in the last 24 hours at La Soufrière, St Vin­cent, as seis­mic ac­tiv­i­ty con­tin­ues to re­main low, since the tremor as­so­ci­at­ed with the ex­plo­sion and ash vent­ing on 22 April 2021.

How­ev­er, the vol­cano re­mains at alert lev­el OR­ANGE, as there is a small, but not in­signif­i­cant, pos­si­bil­i­ty that mag­mat­ic ac­tiv­i­ty might restart, should there be an in­flux of new mag­ma from depth, ac­cord­ing to the lat­est Sci­en­tif­ic Up­date on the La Soufrière Vol­cano, is­sued yes­ter­day by the UWI Seis­mic Re­search Cen­tre.

UWI Seis­mic ex­plains the cur­rent ac­tiv­i­ty at the vol­cano is con­sis­tent with a pe­ri­od of un­rest af­ter an erup­tion, not­ing that this can con­tin­ue for weeks and even months.

“While vol­canic ac­tiv­i­ty has been on a de­cline, there is the con­tin­ued pres­ence of near sur­face hot spots, dai­ly seis­mic ac­tiv­i­ty and per­sis­tent de­gassing,” the lat­est up­date says.

UWI Seis­mic adds: “Mea­sure­ments of the sul­phur diox­ide flux at La Soufrière were car­ried out by boat off the west coast on 3 Au­gust, with the as­sis­tance of the coast­guard. Sev­er­al tra­vers­es were com­plet­ed and yield­ed an av­er­age SO2 (sul­phur diox­ide) flux of 207 tonnes per day.”
