  • Observatory notes down Details of Underwater Volcano’s Fury

An observatory noted down the details of an underwater volcano’s fury as it erupted in real time.

The outburst from a submarine volcano has been caught on camera. It is a mile high promontory which is based on two tectonic plates. A University of Washington study showed how this volcano erupted last year.

This provided an in-depth look into how volcanoes normally behaved. The whole scenario was recorded in incredible detail. The faultlines and the moment of eruption were observed with fidelity. Seismic vibes, sea bed mechanics and the rocks provided the impetus for the volcanic eruption.

The date and location were April 2015 and off the coast of Oregon respectively. With this study, we have a novel savvy of caldera phenomena. The arrangement of electrical power and Internet connections at the level of the sea bed made all this observation possible.

The observatory was finalized just a few months before the observation. This was indeed a novel tool to test the eruption when it took place.

The earth’s volcanoes are an interesting phenomenon and the deeper you go into their mystery the less you know. The Axial Volcano has had three eruptions in the past two decades.

Observatories, similar to the one mentioned a paragraph back, have recorded the data forthcoming from these eruptions. They lend us new ways of knowing the “why” and “how” of these volcanoes.

The inner machinations of these volcanoes are what matter in the final analysis. Prognostications regarding any future eruptions of similar volcanoes will be made easier thanks to this research.

It is a fact that most of earth’s volcanoes erupt underwater. The Axial Volcano rises 0.7 miles and is located 300 km from the Pacific Northwest coastline. Its peak lies below the oceanic surface.

The vibrations generated by its eruption were obviously felt in the vicinity. Also the eruption was noted down with accuracy and in detail by the observatory.

The hot magma spouted from its core and it solidified upon meeting the cold sea water. The images that were captured by the cameras of the observatory show a crisp picture or two of the eruption.

The location of the magma chamber was well-known this time around. Such is a fact as regards underwater volcanoes. The observations also showed that many thousands of tremors occur beneath the ocean floor each and every day. They are normal fare yet we are often unaware of them.
