ATLANTA (AP) — Recent earthquakes demonstrate the need for the nation's nuclear industry to re-evaluate the geologic hazards facing power plants, a process that has already started, the new chair of the U.S. Nuclear Regulatory Commission said this week.

NRC Chairwoman Allison Macfarlane said in an interview that a spate of natural events shows the importance of further study.

"I think what this highlights to us — especially to me as a geologist — is the importance of paying close attention to earth processes and making sure we properly account for them in ensuring that the plants operate safely," Macfarlane said.

In March, the NRC instructed power companies to re-evaluate the seismic and flooding hazards that their power plants face. While such a re-evaluation had been discussed for years, the issue accelerated after a 2011 earthquake and tsunami crippled reactors at the Fukushima Dai-ichi nuclear plant in Japan, leading to multiple meltdowns and radioactive releases. Later that year, the North Anna nuclear plant in Virgina was struck by an earthquake that caused peak ground movement at twice the level at which the plant was designed. No major damage or complications were reported.

Federal officials later cleared that plant to resume operations.
