Revisit notable seismic events through concise archive summaries covering location, depth, felt reports and the uncertainty present in early agency estimates.
These historical reports retain each event’s geographic context. Review dates show recent editorial organization and do not replace the original event dates shown in article titles.
An archive account of a small tectonic event reported as felt in parts of the Korean Peninsula. The report considers location and available shaking observations without treating early parameters as final.

This report records a weak earthquake near the Italian capital and summarizes the regional felt context available at the time. Small events can still be noticeable when they occur near populated areas.

An archive summary of the strong offshore event between Cuba and Jamaica, including broad felt-area and marine-setting context. Official bulletins remain the authority for warning information.

The archived coverage follows a southern Iran earthquake and reports that shaking was also noticed across the Gulf. Distance, depth and local ground conditions can produce varied experiences.

This archive page examines a deep earthquake in the Mariana subduction region. Deep events may be felt over a broad area while producing different surface effects from shallow earthquakes.

The report documents a significant Mindanao earthquake and the developing regional picture. Early impact information is preserved cautiously because initial accounts can change as assessments proceed.

This event page records an earthquake east of Luzon and reports from the wider Manila area. Felt distance alone does not establish the severity of local effects.

This report covers a strong earthquake in the Pacific Ocean west of Oregon. Offshore location does not by itself establish tsunami danger; readers should rely on official warning centers.
Read the report →Earthquake Report arranges archived coverage so that a preliminary number is not mistaken for a complete impact assessment.
They may use different station networks, methods or earthquake scales. Values often converge as more waveform data are reviewed.
A smaller event may merit context when it is shallow, close to a populated area, widely felt or relevant to an ongoing sequence.
Depth changes how seismic energy reaches the surface. Deep events can be felt broadly, but local effects depend on several factors beyond depth.
Not necessarily. Early event pages capture a developing situation. Later agency catalogs and official assessments are preferable for formal research.
Some undersea earthquakes can displace water, but location alone is insufficient. Follow recognized warning centers and local evacuation guidance.
The earthquake glossary explains magnitude, intensity, depth, epicenter, aftershocks and other terms used throughout the archive.
