The worldwide volcanic unrest is picking up around the world with new volcanoes erupting daily around the world.
Warnings have been issued as the only submarine volcano located between Grenada and the Grenadine island of Carriacou, Kick ’em Jenny, is becoming restlessck. Meanwhile, a strong eruption was measured at Sheveluch volcano (Russia) and a high gas pulse jjected from San Miguel volcano in El Salvador.
Warnings issued as volcano near Grenada becomes restless
The National Disaster Management Agency is monitoring an increase in activities taking place at Kick ’em Jenny, the region’s only submarine volcano located between Grenada and the Grenadine island of Carriacou.
In a release early Sunday, the disaster agency (NaDMA) explains:
“The UWI/SRC recorded a high amplitude signal, lasting about 25 seconds, on one of the Grenada stations. The signal was also recorded on a station in Montserrat. This signal follows an increase in the number of background events associated with the Kick-’em-Jenny volcano. In light of the ongoing we are advising all sea users that the 5km (3.1 miles) exclusion zone of Kick ’em Jenny be strictly observed.”
Residents in the St Patrick’s area confirmed having felt the rumbling.
A yellow alert means the volcano is restless; seismicity and/or fumarolic activity are above the historical level or other unusual activity has been observed or can be expected without warning.
About Kick ’em Jenny underwater volcano
According to GVP, Kick ’em Jenny, a historically active submarine volcano 8 km off the north shore of Grenada, rises 1300 m from the sea floor. Recent bathymetric surveys have shown evidence for a major arcuate collapse structure that was the source of a submarine debris avalanche that traveled more than 15 km to the west. Numerous historical eruptions, mostly documented by acoustic signals, have occurred at Kick ’em Jenny since 1939, when an eruption cloud rose 275 m above the sea surface. Prior to the 1939 eruption, which was witnessed by a large number of people in northern Grenada, there had been no written mention of Kick ’em Jenny. Eruptions have involved both explosive activity and the quiet extrusion of lava flows and lava domes in the summit crater; deep rumbling noises have sometimes been heard onshore.
Strong eruption of Shevelush volcano sends ash 10 km high in the sky
Explosive-extrusive eruption of the Shevelush volcano continues. The most recent explosion sent ash up to 10 km a.s.l. at 2:20 pm (UTC) on 30 April. Ash plume continues to drift to the south-southeast from the volcano stretching over adistance of more than 310 km (193 miles) from the volcano.
Ash explosions up to 26,200-32,800 ft (8-10 km) a.s.l. could occur at any time and thus affect international and low-flying aircraft.
High gas pulse ejected from San Miguel (or Chaparrastique) volcano
On April 28, 2017, web cameras installed on the Cerro Pacayal recorded a gas pulse that rose up to 1200 meters above the crater at 2pm. This type of activity has been recorded several times in recent years at the volcano, usuall ending in an gas and ash eruption.
Seisimic vibration continues to fluctuate high above the average (106 to 176 units / hour vs standard value of 50 units) due to continuous injection of magmatic fluids (water vapor, volcanic gas and magma.
Given the behavior of the volcano recorded in recent days, the exit of gas and / or magma from the central crater or on the flanks of the volcano is not excluded. The MARN calls the population to stay away from the summit of the Chaparrastic volcano because of the degree of danger that this represents.
The volcanic unrest continues around the world. And ou better get prepared!
