Volcanic & Seismic Activity 

Underwater Eruption West of Vava’u Island, Tonga

A new submarine eruption has occurred west of Vava’u Island in the Tonga archipelago. Its origin volcano is still somewhat unclear but the eruption, evidenced by fresh pumice rafts and steam plumes, is most likely from a submarine volcano near/at a vent of the small Fonualei volcano.

On Aug 7, an observer sent VolcanoDiscovery.com the following report:

“At around 10:40am on Wednesday 7 August, we noticed large clouds of smoke on the horizon at the location of Fonualei volcano. The plume continued to get larger over the next few hours. It seemed to pause and then erupt again.”

Adding further evidence, a catamaran cruising these waters came across a large raft of fresh pumice (very vesicular, frothy lava so light it can float) produced by the eruption.

The following is an excerpt from the crew’s detailed report published on facebook:

“Catamaran ROAM sailing to Fiji encountered volcanic rocks (Pumice) completely covering the ocean surface at location: 18 55′ S 175 21′ W Time 0800hrs UTC (1900hrs local) 15/8/19.

Rubble slick made up of rocks from marble to basketball size such that water was not visible.


“Sailing on 255T we started seeing some floating rocks of random sizes (marbles to tennis balls) from position 18 46′ S 174 55’W. At position 18 50′ S 175 05′ W we had faint but distinct smell of sulfur. At position 18 54’S 175 19’W we started to see and strike larger floating rocks. We took down all sail. Allowing the boat to continue on bare poles at 2-3kts on COG 255T. As we could no longer smell the sulfur we assumed we would be soon clear of the rubble so elected to continue at slowest speed.


“At approx 0700hrs UTC (1900 local) 15/8/19 at position 18 55′ S 175 21′ W we entered a total rock rubble slick made up of pumice stones from marble to basketball size. The waves were knocked back to almost calm and the boat was slowed to 1kt. The rubble slick went as far as we could see in the moonlight and with our spotlight. We made a turn to starboard and managed to sail clear of the rubble slick under Staysail. We had entered it approx 200m and the edge could be made out in the partial moonlight back to the NE. It was extensive in all other directions.”

UPTICK

Seismic and Volcanic activity has been correlated to changes in our sun.

The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
