That quake, a 7.3 to 7.5 on the Richter magnitude scale, caused nearly 300 features on the Yellowstone landscape to erupt, 160 of which had no previous record of geysers.

Smith traced the three recent earthquake swarms to the Hebgen Lake quake.

"These are a really related," he said.

"We think that much of the seismicity is still aftershocks from that event in 1959. It can go on for hundreds of years."
