There was lava in the area near the wells that the Puna Geothermal Venture facility created.
The plant has nine wells that run as deep as 8,000 feet, according to Wil Okabe, managing director for the County of Hawaii. -Washington Post
8,000 feet is really quite deep. While I understand that those are not the deepest wells created for geothermal energy, in Hawaii that seems deep enough to get to where lava would also be pooling.
For example, it would be deep enough to hit the pool at one of the main volcanoes.
Rocks that are moving upward in the mantle beneath Hawai`i begin to melt about 40 to 60 miles (60 to 100 km) depth. The molten rock, called magma , rises because of its relatively low density. The magma "ponds" in a reservoir 1 to 4 miles (2 to 6 km) beneath the summit. https://www.nps.gov/havo/faqs.htm
In addition to the availability of lava in the area near the wells, it seems that geothermal energy has also been linked to earthquake activity in the past.
An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power -UC Santa Cruz
Moreover, the facility itself is basically right on the location that the set of fissures opened up.
As location of seismic activity is in question here, I also found a map from the US Geological Survey with 30 days of activity for this portion of Hawaii.
Given the proximity of the facility, as well as the fact that these wells were not only near underground lava, but also have been known in other areas to produce earthquakes, what roll, if any, could the Puna GeoThermal Venture have played in the recent fissure activity in Pahoa, Hawaii?
