Ciclu seismic activ? Panică după seismele din Japonia și America de Sud

In the past month, significant earthquakes have struck Indonesia, Colombia, and Mexico, resulting in hundreds of fatalities. A series of seismic events has raised questions about the frequency of earthquakes. From 2016 to 2025, an average of 133 earthquakes of magnitude 6 or higher occurred annually. The US Geological Survey reports around 20,000 earthquakes globally each year, most of which are too weak to be felt. Major earthquakes, particularly those of magnitude 7 or higher, can cause extensive damage and loss of life. The unpredictability of these events remains a challenge for scientists, as tectonic stress accumulates over long periods. Earthquakes are caused by the sudden release of energy in the Earth's crust, leading to vibrations felt on the surface. The potential for destruction increases with the magnitude and proximity to populated areas, as seen in past catastrophic events.
