TOKYO (AP) — Japan dropped its highest-level tsunami alert, issued following a series of major earthquakes on Monday, but told residents of coastal areas not to return to their homes as deadly waves could still come.

The quakes, the largest of which had a magnitude of 7.6, started a fire and collapsed buildings on the west coast of Japan’s main island, Honshu. It was unclear how many people might have been killed or hurt.

The Japan Meteorological Agency reported more than a dozen quakes in the Japan Sea off the coast of Ishikawa and nearby prefectures shortly after 4 p.m.

At least six homes were damaged by the quakes, with people trapped inside, government spokesman Yoshimasa Hayashi said. A fire broke out in Wajima city, Ishikawa Prefecture, and electricity was out for more than 30,000 households, he said.

The agency initially issued a major tsunami warning for Ishikawa and lower-level tsunami warnings or advisories for the rest of the western coast of the island of Honshu, as well as the northernmost of its main islands, Hokkaido.

The warning was downgraded to a regular tsunami several hours later, meaning the waters could still reach up to 3 meters (10 feet). Aftershocks could also slam the same area over the next few days, it said.

Japanese public broadcaster NHK TV initially warned torrents of water could reach as high as 5 meters (16.5 feet).

NHK said the tsunami waves could keep returning, and warnings were continuing to be aired hours after the initial alert. Several aftershocks also rocked the region.

Hayashi stressed that it was critical for people in coastal areas to get away from the oncoming tsunami.

“Every minute counts. Please evacuate to a safe area immediately,” he said.

People returning to get their wallets and other belongings have been known to be swept away and drowned even hours after the first evacuation warning. People were evacuated to stadiums, where they will likely have to stay for a few days.

Hayashi said no reports of deaths or injuries had been confirmed from the quakes, saying the situation was still unclear. Japan's military was taking part in the rescue efforts, he said.

Japanese media footage showed people running through the streets, and red smoke spewing from a fire in a residential neighborhood. Photos showed a crowd of people, including a woman with a baby on her back, standing by huge cracks that had ripped through the pavement.

Some people sustained minor injuries when they tripped and fell while fleeing, or objects fell off shelves and hit them, according to NHK.

Bullet trains in the area were halted, although some parts of the service were restored by evening. Parts of the highway were also closed, and water pipes had burst, according to NHK. Some cell phone services in the region weren't working.

The Meteorological Agency said in a nationally broadcast news conference that more major quakes could hit the area over the next week, especially in the next two or three days.

More than a dozen strong quakes had been detected in the region, with risks of setting off landslides and houses collapsing, according to the agency.

Takashi Wakabayashi, a worker at a convenience store in Ishikawa Prefecture, said some items had tumbled from the shelves, but the biggest problem was the huge crowd of people who had shown up to stock up on bottled water, rice balls and bread.

“We have customers at three times the level of usual,” he said.

Tsunami warnings were also issued for parts of North Korea and Russia.

The Japanese government has set up a special emergency center to gather information on the quakes and tsunami and relay them speedily to residents to ensure safety, Prime Minister Fumio Kishida told reporters.

The latest warning was the first time since the 2011 disaster that a tsunami warning of this magnitude was issued.

Government spokesman Hayashi told reporters that nuclear plants in the affected area had not reported any irregularities on Monday. Nuclear regulators said no rises in radiation levels were detected at the monitoring posts in the region.

TOKYO (AP) — Japan issued tsunami alerts and ordered evacuations following a series of earthquakes on Monday that started a fire and trapped people under rubble on the west coast of its main island.

The Japan Meterological Agency reported more than a dozen quakes off the coast of Ishikawa and nearby prefectures shortly after 4 p.m., one of them with a preliminary magnitude of 7.6.

The agency issued a major tsunami warning for Ishikawa and lower-level tsunami warnings or advisories for the rest of the western coast of the island of Honshu, as well as the northernmost of its main islands, Hokkaido.

Japanese public broadcaster NHK TV warned torrents of water could reach as high as 5 meters (16.5 feet) and urged people to flee to high land or the top of a nearby building as quickly as possible.

Government spokesman Yoshimasa Hayashi said it was critical for people in coastal areas to get away from the oncoming tsunami.

A tsunami of about 3 meters (about 10 feet) high was expected to hit Niigata and other prefectures on the western coast of Japan, and the waves were confirmed to have reached parts of the coastline.

At least six homes were damaged by the quakes, with people trapped inside. A fire has broken out in Wajima city, Ishikawa Prefecture, and electricity is out for more than 30,000 households, Hayashi said.

He said no reports of deaths or injuries had been confirmed, saying the situation was still unclear. Japan's military was taking part in the rescue efforts, he said.

Bullet trains in the area were halted. Parts of the highway were also closed, and water pipes had burst, according to NHK. Some cell phone services in the region weren't working.

Tsunami warnings were also issued for parts of North Korea and Russia. Russian officials issued a tsunami alert for the island of Sakhalin, warning that areas across the island’s west coast could be affected by the waves.

In nearby South Korea, the weather agency urged residents in some eastern coastal towns to watch for possible changes in sea levels. Tsunami waves that hit later later can be bigger than the initial ones.

He reiterated the warning for immediate evacuation in affected areas.

MEXICO CITY — Mexico's Popocatepetl volcano rumbled to life again this week, belching out towering clouds of ash that forced 11 villages to cancel school sessions.

The residents weren't the only ones keeping a close eye on the towering peak. Every time there is a sigh, tic or heave in Popocatepetl, there are dozens of scientists, a network of sensors and cameras, and a roomful of powerful equipment watching its every move.

The 17,797-foot (5,426-meter) volcano, known affectionately as "El Popo," has been spewing toxic fumes, ash and lumps of incandescent rock persistently for almost 30 years, since it awakened from a long slumber in 1994.

The volcano is 45 miles (72 kilometers) southeast of Mexico City, but looms much closer to the eastern fringes of the metropolitan area of 22 million people. The city also faces threats from earthquakes and sinking soil, but the volcano is the most visible potential danger — and the most closely watched. A severe eruption could cut off air traffic, or smother the city in clouds of choking ash.

Ringed around its summit are six cameras, a thermal imaging device and 12 seismological monitoring stations that operate 24 hours a day, all reporting back to an equipment-filled command center in Mexico City.

A total of 13 scientists from a multidisciplinary team take turns staffing the command center around the clock. Being able to warn of an impending ash cloud is key, because people can take precautions. Unlike earthquakes, warning times can be longer for the volcano and in general the peak is more predictable.

On a recent day, researcher Paulino Alonso made the rounds, checking the readings at the command center run by Mexico's National Disaster Prevention Center, known by its initials as Cenapred. It is a complex task that involves seismographs that measure the volcano's internal trembling, which could indicate hot rock and gas moving up the vents in the peak.

Monitoring gases in nearby springs and at the peak — and wind patterns that help determine where the ash could be blown — also play a role.

The forces inside are so great that they can temporarily deform the peak, so cameras and sensors must monitor the very shape of the volcano.

How do you explain all of this to 25 million non-experts living within a 62-mile (100-kilometer) radius who have grown so used to living near the volcano?

Authorities came up with the simple idea of a volcano "stoplight" with three colors: green for safety, yellow for alert and red for danger.

For most of the years since the stoplight was introduced, it has been stuck at some stage of "yellow." The mountain sometimes quiets down, but not for long. It seldom shoots up molten lava: instead it's more the "explosive" type, showering out hot rocks that tumble down its flanks and emitting bursts of gas and ash.

The center also has monitors in other states; Mexico is a country all too familiar with natural disasters.

For example, Mexico's earthquake early alert system is also based at the command center. Because the city's soil is so soft — it was built on a former lake bed — a quake hundreds of miles away on the Pacific coast can cause huge destruction in the capital, as happened in 1985 and 2017.

A system of seismic monitors along the coast sends messages that race faster than the quake's shock waves. Once the sirens start blaring, it can give Mexico City residents up to half a minute to get to safety, usually on the streets outside.

ANCHORAGE, Alaska — A swarm of earthquakes occurring over the 
past few weeks has intensified at a remote Alaska volcano dormant for 
over a century, a possible indication of an impending eruption.

The
 Alaska Volcano Observatory raised the alert level to advisory status 
for Tanaga Volcano late Tuesday after the quakes became very vigorous.

“We
 started seeing a whole lot of earthquakes occurring, one after the 
other, several per minute,” said John Power, a research geophysicist 
with the U.S. Geological Survey stationed in Anchorage at the Alaska 
Volcano Observatory.

There have been hundreds of small 
earthquakes, none larger than magnitude 2.75, but they are concentrated 
beneath the summit of the volcano, he said.

“That indicates that we’re seeing significant unrest at the volcano,” Power said.

“Whether
 or not this will lead to an eruption is something we can’t say at this 
point in time,” he said. “But we are concerned about it enough that we 
have gone and elevated the warning level.”

While the increase causes concern, he said many times earthquake activity will drop off with no eruption.

“It’s anybody’s guess as to where this particular round of earthquake activity may end up,” he said.

The
 volcano is on an uninhabited island in the western Aleutians, about 
1,250 miles southwest of Anchorage. There are no 
communities or structures there, but Adak, a city of about 170 residents
 on another island, is about 65 miles away and could 
see ashfall.

If the volcano were to erupt, the biggest threat 
would be to aircraft. The Aleutians are below the routes that jets fly 
between North America and Asia. Volcanic ash is angular and sharp and 
can cause an airplane engine to shut down. Previous eruptions had both 
ash clouds and viscous lava that moves very slowly away from the 
mountain, much like what happened at Mount St. Helens in Washington 
state in 1980.

“It’s very different than what you would see, for 
example, in Hawaii, Kilauea or Mauna Loa, where you see these beautiful 
red rivers of lava flowing down the side of the volcano," Power said.

Tanaga
 is actually part of a three-volcano complex on the island. It’s the 
tallest of the three at 5,925 feet. It sits in the 
middle, with Sajaka, a 4,443-foot volcano to its west. Sajaka had an 
older cone that collapsed into the North Pacific Ocean with a new cone 
that has emerged.

To the east of Tanaga is Takawangha, a 4,754 
-foot volcano that is mostly ice-covered except for four 
craters, the Alaska Volcano Observatory says.

The last known eruption for Tanaga was in 1914. It erupted twice in the late 1700s and again in 1829.

The
 observatory in a release said there are no known eruptions of 
Takawangha or Sajaka. However, field work has indicated that eruptions 
may have occurred from those volcanos and were attributed to Tanaga.
