In the summer of 2017, the Yellowstone volcano experienced a powerful earthquake with more than 2,500 earthquakes. This has been recognized as the largest earthquake in the history of the supervolcan.
According to scientists, a series of simultaneous earthquakes is a typical phenomenon in this region that is constantly shaking. However, the case of 2017 was really serious, even if the causes of the process were not known.
The tremors began near the western border of Yellowstone National Park and lasted from June to early October. After the earthquake, scientists gathered data to badyze it and determine the cause of the disaster.
At the present time, experts from the US Geological Survey (USGS) claim to have found the main cause. In particular, they have been able to map the evolution of the many tremors that occurred in the park, called Maple Creek, in 2017.
This week, #Yellowstone #CalderaChronicles pays special attention to the large number of earthquakes in Maple Creek 2017 –
According to seismologist David Shelly, the data obtained during the earthquake of 2017 provided detailed and detailed information that scientists did not have before.
When badyzing new data, the scientific team revealed that the phenomenon was related to the activity. groundwater that has leaked through small holes. According to the researchers, the water flows below the surface of the Earth and changes the structure of the elbows.
Thus, multiple earthquakes generally occur near volcanoes because magma emissions accompany a release of water, they conclude: explaining that groundwater is under great pressure . Once released, it comes into contact with fragile rocks, related to seismic processes, and can consequently break them, causing earthquakes.
