Scientists are planning a “CAT scan” of a British Columbia volcano to help harness the underground heat that turns rock into magma for renewable energy.
Cayley’s last lava flow was back in the 1700s, but plenty of heat remains. At nearby Mount Meager, a well drilled in the 1970s showed temperatures of 250 C at 1.5 kilometres depth. He and his colleagues are trying to find ways to help drillers improve their hit rate by building a 3-D map of Cayley’s innards – without using traditional tools such as seismic lines.
“We have to go all around the volcano, so you’re looking into it from all these different angles,” Grasby said.
