A deadly 7.4 magnitude earthquake hit the coast of Japan’s Fukushima prefecture on Wednesday, injuring dozens of people.

For some, the incident brought back painful memories of 2011, when an earthquake triggered a tsunami that sparked a nuclear meltdown at the Fukushima power plant, a disaster that is still felt to this day.

Although the quake struck a similar area, Wednesday’s quake did not cause a national emergency – for a number of reasons.

Here’s what you need to know.

What, where and when?

The quake struck around 12:30 a.m. local time (11:30 a.m. ET) off Fukushima, north of the capital Tokyo.

It was originally designated as a magnitude 7.3 earthquake, but was upgraded to 7.4 on Thursday.

Since Thursday, all tsunami warnings issued after the earthquake have been lifted.

The epicenter of Wednesday’s quake was about 55 miles from the center of the devastating 2011 quake.

Robert Geller, seismologist and professor emeritus at the University of Tokyo, suggested Wednesday’s quake could have been an aftershock from 2011. “In geological terms, aftershocks will persist for 50 to 100 years, but over time, the frequency aftershocks and their size will decrease,” he said.

Four people, including a man in his 60s, have been confirmed dead and at least 160 others injured, Japanese authorities said on Thursday.

Could other earthquakes or tsunamis occur?

The Japan Meteorological Agency warned the public to remain alert for aftershocks and the possible risk of landslides or landslides. He also urged people in affected areas to stay away from the coast and not enter the sea.

In a tweet, the prime minister’s office said the government had established a countermeasures office that will work with local governments to implement emergency measures, including search and rescue of potential victims.

Geller, the seismologist, said Japan can expect more aftershocks next week that will gradually diminish.

Although he said it was also possible that Wednesday’s quake was a “forecast” ahead of a larger quake, warning that the chances of it happening are very low but “not zero”.

“Yesterday’s earthquake is a good reminder for Japanese people to remember that Japan is earthquake-prone and earthquakes can strike at any time,” he said. “So people have to be prepared.”
