FOIA Request PGV and the May 3rd 2018 Leilani Estates Eruptions

This page is home to a FOIA Requested by The Earth Harmony Foundation in regards to the LAVA outbreaks starting May 3, 2018 in Leilani Estates, Big Island of Hawaii .

 

This is the home for the information requested  and received by The Earth Harmony Foundation Environmental Committee in regards to potential triggering of the lava eruptions by operations at the PGV Puna Geothermal Venture.

Below are links to the response letter and the information made available and granted  from the EPA including information pertaining to the operations and a report by Dr. Catherine Kenedi where she reports her findings…

  1. …Large faults interact to produce local areas of stress transfer that lead to fracturing and permeable networks; these networks allow for high-temperature hydrothermal circulation.’
  2. …The most extraordinary geologic aspect of the Puna geothermal field is the confirmed presence of dacitic magma at approximately 2.5 km depth (Marsh et al., 2008; Teplow et al., 2008). The magma was discovered during routine drilling at PGV. The drill team inadvertently drilled into active magma, which repeatedly oozed up the well bore while the drill bit was withdrawn and relowered; drilling was stopped when clear glass chips came out as cuttings. The magma demonstrates both the unpredictable nature of this system and, perhaps, an explanation for the local high heat levels. Much work remains in terms of discovering the source of the magma, and we intend our contribution to be towards understanding the structure that encouraged the magma to accumulate and differentiate under the Puna geothermal field.
  3. She also shows a correlation between the injections by PGV and earthquakes, of which over 6,000 mostly small were detected.
