NEW YORK, BRONX (ORDO News) — Scientists have reported that the Earth‘s seismic activity is steadily increasing, and not only on land.
According to the journal Nature Communications, scientists are seeing an increase in storm activity across the planet, accompanied by unusual fluctuations in ocean waves, even at the depths of the ocean floor.
Experts define this phenomenon as “global microseism” – a continuous background noise generated by stormy ocean waves. Interestingly, this phenomenon has become noticeable even with traditional seismographs designed to record earthquakes.
There are two main types of signals generated by storm waves. Powerful variants, pulsations with periods ranging from 8 to 14 seconds, cause changes in pressure on the ocean floor.
Other signals are created by traveling waves that push and pull on the seabed, especially in areas with water depths of about 300 meters.
Recent research confirms that global ocean wave energy is increasing. At the end of the last century, the average annual growth was 0.27%, and in the current century this figure has risen to 0.35%.
Scientists attribute this increase to climate change: rising temperatures on the planet lead to active absorption of heat by the ocean.
This, in turn, increases the mobility of ocean waves and causes increased seismic activity, which ultimately threatens coastlines.
These new discoveries highlight the importance of more research and attention to the impact of climate change on various aspects of nature, including seismic activity.
