The Strongest Earthquakes Recorded Previously

• An earthquake with a magnitude of 8.8 occurred in Russia on July 30, 2025.
• Preliminary reports about the magnitude have reached many countries in the Pacific Ocean.
• The largest earthquakes recorded in history have been documented.

Earlier in the day, on July 30, 2025, one of the strongest earthquakes was recorded in the Far East of Russia. This earthquake, with a magnitude of 8.8, surpassed the previous records set in Japan and Alaska, which were noted for their significant impact on people in the Pacific region.

Preliminary reports about the potential magnitude have reached Hawaii, the southern and central parts of America, as well as the islands of the Pacific Ocean south of New Zealand. According to official sources, the potential magnitude could last for a longer duration.

Here are some of the largest earthquakes recorded previously, according to data from the United States Geological Survey.

1. Chile

In 1960, a magnitude 9.5 earthquake struck central Chile, known as the Valdivia earthquake or the Great Chilean earthquake. It resulted in over 1600 deaths, a significant portion of which occurred due to the tsunami it generated.

2. Alaska

In 1964, a magnitude 9.2 earthquake occurred in the Prince William Sound area of Alaska, lasting nearly five minutes. More than 130 people died, and there were significant ground shifts and tsunamis that caused serious damage.

3. Sumatra, Indonesia

In 2004, a magnitude 9.1 earthquake struck, causing tsunamis that devastated southeastern and southern Asia, killing 230,000 people, of which over 167,000 died in Indonesia.

4. Tōhoku, Japan

In 2011, a magnitude 9.1 earthquake occurred off the northeastern coast of Japan, generating tsunamis that caused significant destruction. Over 18,000 people died.

5. Kamchatka, Russia

In 1952, a magnitude 9.0 earthquake struck, causing significant damage but did not result in direct casualties.

6. Biobío, Chile

In 2010, a magnitude 8.8 earthquake occurred in Chile, resulting in over 500 deaths.

7. Esmeraldas, Ecuador

In 1906, a magnitude 8.8 earthquake struck, causing fatalities estimated between 500 and 1500.

8. Alaska

In 1965, a magnitude 8.7 earthquake occurred, generating waves up to 11 meters high.

9. Tibet

In 1950, a magnitude 8.6 earthquake resulted in the loss of more than 780 lives.

10. Sumatra, Indonesia

In 2012, a magnitude 8.6 earthquake occurred, which did not cause significant damage but increased pressure on the seismic zone, similar to the events of 2004.
