Hawaii Volcanic Eruption
« on: May 07, 2018, 08:19:28 PM »
Don’t know if anyone has been following the recent volcanic activity on the big island... but, some incredible images have been coming out in recent days:

  ::scratch::

It's not that kind of volcano that propels volumes of ash and gases into the atmosphere that leads to a period of global cooling, if that's what you mean. Kilauea on the big island has been continuously erupting since 1983, which means just a lava flow for the most part.

There's been an increase of magma upwelling in that hot spot recently, and one of the calderas collapsed a couple of weeks ago, which rerouted the lava flow underground, leading to a break in the surface in a new area, which is now causing these lava flows in residential areas.

Coinciding with the activity, there was also a 6.9 mag earthquake there last week. That actually triggered a minor localized tsunami.

Fear is now growing that Kilauea is fixing to blow its top.

It is the newest threat from the Kilauea volcano, which started to erupt eight days ago on the US state’s Big Island, the National Park Service said.

Lava levels in the crater are going down, say scientists, which means it may be clogging up before a massive blast.

US Geological Survey geophysicist Ingrid Johanson said movement of the molten rock opened space for lava to drain underground which reduced the height of a lava lake at the summit.

As the lava lake levels fall below the groundwater table, water can start interacting with the magma, heating it up and creating steam, said USGS scientist Donald Swanson.

Quote
If rocks fall from the walls surrounding the magma in the volcano, the rocks can form a dam and if the steam builds pressure, “it can eventually burst out in an explosion,” Mr Swanson said.

 

NASA produced a satellite image of how high the plumes could be in the area. in some parts they are expected to reach 1.5km (0.9 miles).

The lava could interact with the groundwater by the middle of this month, scientists have estimated.

When you have magma and groundwater interacting with each other that can turn deadly pretty quickly. Phreatic explosions in the East Rift zone could be huge and volatile...spent a lot of time on this in my Petrology class back in 2013.
