A major earthquake that has happened in the past is often referred to as a seismic event or a historic earthquake. The specific location where the earthquake occurred is known as the earthquake's epicenter.
Portland, Oregon is 28.4 miles from St Helens, Oregon.
It means that the earthquake is large and powerful.
California sits on the San Andreas Fault, a major tectonic boundary where two of Earth's tectonic plates interact. The movement of these plates causes stress to build up, which can lead to earthquakes. Due to the history of seismic activity in the region, scientists predict that a major earthquake in California is likely to occur in the near future.

The city most likely to experience a major earthquake would be located near the boundaries where tectonic plates meet, such as in regions along the Pacific Ring of Fire, where there is high seismic activity due to plate interactions. Cities like Tokyo, Los Angeles, or Istanbul are more prone to major earthquakes due to their proximity to plate boundaries.

A major earthquake is most likely to occur along tectonic plate boundaries, such as the Pacific Ring of Fire. This area encircles the Pacific Ocean and is known for high seismic activity. Subduction zones and transform faults are common locations for major earthquakes to occur.
The hypothesis is called the "earthquake recurrence interval" or "seismic gap" hypothesis. It suggests that segments of active faults that have not experienced an earthquake for a significant duration may be more likely to produce a major earthquake, as stress accumulates over time. This concept is important in earthquake forecasting and risk assessment.
The 1933 Sanriku earthquake was a major earthquake.

Countries such as Australia, most of Europe, and parts of the Middle East like Qatar and Bahrain are less likely to experience earthquakes due to their location on stable continental plates, away from major tectonic boundaries. However, no country is completely immune to earthquakes as they can still occur in unexpected areas.
