Yellowstone volcano TREMORS: Seismometers detect ‘seismic ENERGY’ prompting need for study

Jamie Farrell, chief seismologist at the Yellowstone Volcano Observatory, said the study funded by the National Science Foundation, has found the most likely source of the tremors.

The geologist explained in the weekly Yellowstone Caldera Chronicles: “There are two ways that the ocean’s waves cause seismic shaking.

“The direct interaction of ocean waves and the solid ground near the shoreline – single frequency microseism – and the interaction of two sets of wave trains travelling in different directions in the open ocean – double frequency microseism.

“The double frequency microseism can be due to two storm systems and their associated wave trains, interacting in the open ocean, or caused by waves interacting with reflected waves near the coastline.
