Hurricane Irma is so strong it's showing up on seismometers equipment designed to measure earthquakes.
"What were seeing in the seismogram are low-pitched hums that gradually become stronger as the hurricane gets closer to the seismometer on the island of Guadeloupe," said Stephen Hicks, a seismologist at the University of Southampton in the United Kingdom.
The noise is likely caused by high winds which cause tiny motions in the ground and also by trees swaying in the wind, which also transfers energy into the ground, he said. The seismometer is located close to the ocean, so waves crashing along the coastline reverberate around the island, also generating seismic energy, Hicks added.

(40,416 posts)Seismology has rather precise instrumentation. It is not surprising that a hurricane can be detected by seismologists thousands of miles away.
After all, one cannot explode a bomb on earth without it being detected. The guys at CalTech are rather good at it.
