A 7.0-magnitude earthquake struck early Saturday morning in Japan’s Kyushu island, the same region a magnitude-6.2 quake struck two days earlier.

The U.S. Geological Survey reported that the latest quake struck just west-southwest of Kumamoto-shi and about 8 miles south-southeast of Ueki — the epicenter of the late-Thursday tremor that left nine dead.

It was not immediately clear if anyone was injured or killed as a result of Saturday morning’s seismic event. Nor was it clear how much damage, if any, had been caused.

But it did prompt the Japan Meteorological Agency to issue a tsunami advisory for coastal regions of Japan on the Ariake Sea and Yatsushiro Sea around 2 a.m. Saturday (1 p.m. ET Friday). The agency subsequently lifted all tsunami warnings and advisories.

Tsunami advisories are issued when the tsunami height is expected to between 0.2 and 1 meter (0.65 to 3.3 feet). A warning would be for larger tsunamis.

Baby pulled from rubble after earlier quake

This happened about a full day after rescuers found an 8-month-old baby girl — alive — in the ruins of a home destroyed by the earlier quake on Japan’s Kyushu island.

Rescuers had been told there was a baby inside the collapsed house, but aftershocks from the Thursday quake prevented the use of heavy equipment at the site.

Yet, after six hours trapped, she was pulled from the rubble early Friday.

“It was miracle she was unharmed,” Hidenori Watanabe, a spokesman for the Kumamoto Higashi fire department, told CNN.

Fifty rescuers — wearing dark uniforms and white hard-hats with lights — scoured the large pile of rubble that just hours before had been a home. The infant’s mother and grandmother had managed to escape.

The little girl was finally found safe amid the debris in a space under one of the house’s pillars, according to Watanabe.

This happened in the middle of the night, in an area lit only by spotlights.

Carefully, rescuers passed the barefooted baby to one another, before she finally got to crews on the ground and was taken swiftly away.

Prime Minister on the way to the site

Japanese Prime Minister Shinzo Abe will visit the earthquake-hit area in Kumamoto prefecture on Saturday, he said at a meeting at Emergency Response Headquarters in Tokyo on Friday evening.

“I would like to see the site with my own eyes and hear from the victims directly,” Abe said.

Search crews are continuing to dig through rubble looking for other people trapped under collapsed buildings.

The quake struck near Ueki, the U.S. Geological Survey said. Dozens of smaller aftershocks followed.

“The ground shook for about 20 seconds before the 6.2-magnitude quake stopped,” witness Lim Ting Jie said.

Two deaths occurred in Mashiki, the Kumamoto Prefecture office said. One person died in a collapsed house, and the other died in a fire caused by the quake. Journalist Mike Fern told CNN that scores of buildings had either collapsed or caught fire, while the tremors triggered landslides, tore up roads and in one case, derailed a bullet train.

Nearly 800 people were injured, 50 severely. The prefecture office said 44,449 people had evacuated.

Abe told parliament early Friday that he’d mobilized 3,000 members of Japan’s Self Defense Force, police and fire services to join the rescue effort overnight. He said the government is “racing against the clock and will provide more personnel if necessary.”

More shocks

Gen Aoki, director of the Japan Meteorological Agency’s earthquake division, warned more aftershocks could occur over the next week.

“This is an earthquake that is going to shake for a long time,” CNN meteorologist Chad Myers said.

That could mean many more building collapses.

“The buildings that were damaged in the original shock have now been redamaged or reshaken,” he said. “And all of a sudden you have a cracked building, and it wants to fall down with the second shake.”

Robert Geller, a seismologist at Tokyo University, said the quake also increases the likelihood of eruptions from Mount Aso, Japan’s largest active volcano — though there have been no reports of extra activity, according to the Meteorological Agency.

Huge impact

An estimated 750,000 people felt “violent to severe shaking,” Myers said.

“The strongest shaking was right where the most people live” in the area, he said.

While the magnitude might not seem extreme, the shallow depth of the quake — just 10 kilometers (6.2 miles) — is significant.

“When you have a shallow earthquake, such as this one is, you have the potential for more damage because the shaking is close to the surface,” John Bellini of the U.S. Geological Survey said.

In addition to destroying 19 houses, the quake hurled items off store shelves and littered streets with rubble.

But there’s one bit of good news: The quake was centered mostly under land, not an ocean, meaning it did not spawn a major tsunami.

Regulators also moved to allay fears around the country’s nuclear plants, with the country’s only facility currently online in Sendai unaffected. The Genkai plant, which is located on Kyushu, also reported no problems.

A high-risk area

Japan, which sits along the so-called Ring of Fire, is no stranger to earthquakes.

The largest recorded quake to hit Japan came on March 11, 2011, when a magnitude-9.0 quake centered 231 miles (372 kilometers) northeast of Tokyo devastated the country.

That quake triggered a massive tsunami that swallowed entire communities in eastern Japan. It caused catastrophic meltdowns at the Fukushima Daiichi nuclear power plant.

The disaster killed about 22,000 people — almost 20,000 from the initial quake and tsunami, and the rest from health conditions related to the disaster.

Jie said Thursday’s quake gave him a new appreciation for life.

“This experience has helped me to treasure my family members and relatives even more, and not take what I have and the people who support me for granted.”
