Pacific Ring of Fire
This is the world's most active earthquake belt. It includes Japan, the Philippines, Indonesia, New Zealand, Alaska, the west coast of the Americas, Kamchatka, and the Kuril Islands.

Earthquake records often appear in long clusters because many events happen near active plate boundaries. These are the main belts behind the patterns on the map.
This is the world's most active earthquake belt. It includes Japan, the Philippines, Indonesia, New Zealand, Alaska, the west coast of the Americas, Kamchatka, and the Kuril Islands.
This belt runs from the Mediterranean through Turkey, Iran, Central Asia, the Himalayas, and western China. Many inland Asian earthquakes come from this collision zone.
Earthquakes also occur along ocean ridges such as the Mid-Atlantic Ridge and Indian Ocean ridges. Many of these events happen under the sea.
Greenland, Northern Europe, and much of inland Siberia are relatively stable continental regions, so they usually show fewer earthquake records.
Most earthquakes occur along active plate boundaries. Greenland, Northern Europe, and much of inland Siberia are relatively stable continental areas, so this dataset has fewer records there. Russia's Far East, including Kamchatka and the Kuril region, is much more active because it sits along the Pacific earthquake belt.
When Radius is None, the tool loads earthquake records inside the current map view. This keeps the map responsive while still showing global patterns.
