For about two weeks we have been watching the after effects of the 6.9 magnitude earthquake on the south side of the island of Hawaii. The earthquake was the second in one day; the previous event was a 5.0 magnitude. At that time, May 4, 2018 there were no concerns with tsunami after effects. Today, two weeks later there are serious concerns and the watch system has upgraded their readiness alert from orange to red.
The earthquakes took place in the Hawaii National Volcano Parks region subsequent to the lava field inside Kilauea volcano beginning to recede and essentially leaking into the surrounding underground lava fields. The pressure upon the surface caused the fissures to open in the Leilani Estates neighborhood east of the national volcano park. Those fissures over the last two weeks have continued to spread in a direct line east toward the southeast coast of Hawaii. In the path of these pressure release cracks in the surface are a main highway, now closed and the Puna Geothermal Venture plant where highly flammable heat exchange liquid is stored. The evacuation of that liquid has been an ongoing operation. The Hawaii Electric site gives us this information;
Geothermal energy comes from volcanic heat stored beneath the earth’s surface. Underground reservoirs of water heated by volcanic activity can be tapped for steam to generate electricity. On Hawaii Island, Puna Geothermal Venture operates an advanced binary-cycle power plant. The heat from hot water in a heat exchanger generates vapor from a working fluid with a low-boiling point. This vapor drives a turbine to produce electricity. The water, which never comes in contact with the working fluid, is then injected back into the ground to reheat.”
While this is a major safety concern, there is an even bigger potential impact Pacific-wide. The very real possibility of the southern part of the island collapsing into the ocean in a region called the Hilina Slump. jn14 found a 3-D model clip that demonstrates what could happen, Pacific wide. The clip is about 17 minutes however; 3-5 minutes of viewing will give our readers an idea of the potential effects reaching as far as the 30 meters into the California coastline.
Our source, @MrMBB333 has been following the earthquake and subsequent events since it happened and alerted his viewers to the potential of the collapse of the Hilina Slump. Here is his report from May 12, 2018 just five days ago.
He has done an outstanding job of reporting on these events, including live boots-on-the-ground reporting from native Hawaiian Ikaika Marzo. The link to MrMBB333’s YT channel is in the Sources section below.
So what does it all mean?
The tsunami alert warning system changing from orange to red is alarming for Hawaiians to be sure but now the potential for a mega-tsunami threatens the California coast as well as other island nations in the Pacific. This is serious stuff. One wonders at the nutty focus of Governor Jerry Brown on the Sanctuary City and border wall issues when his whole state coastline is in danger. One also must reconsider the wisdom of fracking and it’s unintended consequences for the regions adjacent to its operations. Fracking as you may recall, is the forcing of water into the underground oil fields to extract oil. But that is a discussion for another day.
