Alexei Solomatin, a researcher at the Kamchatka branch of the Unified Geophysical Circle of the Russian Academy of Sciences, points out that the earthquake caused faults and changes in the activity of geothermal springs and volcanoes.
According to a report presented by the researcher to the Russian conference "Direct and Reverse Problems of Seismology" , the Kamchatka earthquake of July 2025 was the strongest since 1952, and resulted in significant changes in the groundwater layers of the Earth's crust , manifested in the emergence of new faults and changes in the activity of thermal springs and volcanoes .
The report explained that the earthquake caused regional expansion and significant deformation of the upper aquifers , clarifying that rock deformation is the process of displacing rock particles , leading to changes in the size or shape of individual rock units or parts of rock masses. These changes resulted in the emergence of multiple seismic anomalies following the earthquake.
The report indicated that the enormous extent of the earthquake's source and the movements along the fault plane, reaching up to 40 meters at the surface , caused a range of geodynamic anomalies , which manifested themselves in:
Several volcanoes have begun to erupt
Water level drop in wells
Water flow has stopped in some fields
New hot water fountains appear
It is reported that the Kamchatka earthquake on the morning of July 30, 2025 , measured 8.8 on the Richter scale and caused a tsunami in the Pacific Ocean , prompting authorities in Japan, the United States and the Philippines to issue urgent tsunami warnings.
