Earthquakes are one of nature’s most powerful and awe-inspiring phenomena. They occur when the Earth’s tectonic plates, which are massive slabs of rock that make up the planet’s surface, suddenly release energy that has been building up over time. This energy release causes the ground to shake, sometimes with devastating effects.
One of the most recent earthquakes struck the Kyushu region of southern Japan on January 13, 2025
1
. This earthquake had a preliminary magnitude of 6.9, but was later revised down to 6.6
2
. The quake was centered at a depth of 30 kilometers and triggered tsunami advisories for waves up to one meter high in the Miyazaki and Kochi prefectures
1
. Fortunately, there were no reports of significant damage or casualties

Japan is located along the “Ring of Fire,” a horseshoe-shaped area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur
1
. This region is home to about 75% of the world’s active volcanoes and experiences about 90% of the world’s earthquakes
1
. The Ring of Fire is the result of tectonic plate boundaries interacting with each other, causing frequent seismic activity

.
When tectonic plates move past each other, they can get stuck due to friction
1
. Over time, stress builds up until the plates suddenly slip, releasing energy in the form of an earthquake
1
. The energy travels through the Earth in the form of seismic waves, which can cause the ground to shake violently.
Earthquakes can have a wide range of impacts, from minor tremors that go unnoticed to catastrophic events that cause widespread destruction. The severity of an earthquake’s impact depends on several factors, including its magnitude, depth, distance from populated areas, and the local building infrastructure.
