Some facts about the strongest earthquakes ever recorded


One of the strongest earthquakes ever recorded struck Russia’s Far East early Wednesday, causing tsunami waves to wash ashore in Japan and Alaska and calls for people around the Pacific to be on alert or move to higher ground.

The 8.8 magnitude temblor set off warnings in Hawaii, North and Central America and Pacific islands south toward New Zealand, with officials warning that the potential tsunami danger may last for more than a day.

Here’s a glance at some of the most powerful earthquakes recorded previously, according to the U.S. Geological Survey.

1. Biobío, Chile

A 9.5 magnitude earthquake struck in a central region of Chile in 1960. Known as the Valdivia earthquake or Great Chilean earthquake, the largest ever recorded temblor resulted in more than 1,600 deaths in the country and beyond, most of which were caused by resulting large tsunami. Thousands of people were injured.

2. Alaska

In 1964, a 9.2 magnitude earthquake jolted the Alaska’s Prince William Sound, lasting for almost 5 minutes. More than 130 people were killed in the largest recorded earthquake in the U.S. and subsequent tsunami. There were huge landslides and towering waves that caused severe flooding. The event was followed by thousands of aftershocks for weeks after the initial quake.

3. Sumatra, Indonesia

A 9.1 magnitude earthquake and resulting tsunami devastated Southeast and South Asia and East Africa in 2004, killing 230,000 people. Indonesia alone recorded more than 167,000 deaths as entire communities were wiped out.

4. Tohoku, Japan

A magnitude 9.1 earthquake struck off the coast of northeastern Japan in 2011, triggering a towering tsunami that smashed into the Fukushima nuclear plant. It knocked out power and cooling systems and triggered meltdowns in three reactors. More than 18,000 people were killed in the quake and tsunami, some of whom have never been recovered.

5. Kamchatka, Russia

In 1952, a magnitude 9.0 quake caused significant damage but no reported deaths despite a tsunami that hit Hawaii with 9.1-meter (30-foot) waves.

6. Biobío, Chile

A massive 8.8 magnitude earthquake hit central Chile in 2010, shaking the capital for a minute and half and setting off a tsunami. More than 500 people were killed in the disaster.
