There were no immediate reports of injuries. It was the latest in a series of small-scale eruptions at the volcano in Kumamoto Prefecture since April. No volcanic cinders were detected but the agency warned of volcanic gas.
The agency raised Mt. Aso's volcanic alert level to 2 on a scale of 1 to 5 in April, urging people not to approach the crater. Local municipalities have restricted entry to areas within 1 kilometer of the crater.

Rare Booby birds, known for living in the tropics, have been spotted off the Southern California coast in recent days.
A handful of Booby birds have been spotted off of Long Beach and Dana Point in recent days by boaters who have captured images of the rare sightings.
The report from Dana Point came Thursday, July 25, by boat Capt. Frank Brennan, who was out on a fishing charter aboard the vessel Reel Fun.
Brennan said he immediately recognized it was one of the tropical species — either a Nazca or Masked Booby — and took a photo to share with bird expert Robin Lowe, who later identified the bird as a Nazca Booby.
In some spots, the bubble plumes are plentiful enough to resemble florescent lace curtains in the glow of a camera deployed by NOAA Ocean Exploration and Research.
Adding to the spectacle: The bubbles rise amid "dense" beds of mussels that are seen in a video stretching as far as the camera lens could penetrate.
The bubbles are methane gas, seeping constantly from the ocean floor off Bodie Island, at a depth of about 1,300 feet, according to a report by the NOAA-backed team.

Comment: In recent times hundreds of methane plumes have been discovered erupting along the US Atlantic coast, as well as for the first time in deep Arctic Ocean areas.
It is likely this increased methane outgassing and undersea volcanic activity (it is estimated there are up to one million of these 'submarine volcanoes') are contributory factors to the devastating huge ocean 'dead zones' which have quadrupled around the world since 1950, including in Atlantic open waters for the first time.
The significant increase of fish die offs and strange migratory behaviour of marine life could be considered other potential signs of such activity.
Methane outgassing may also be a significant factor for over 100 wildfires burning across the Arctic region, which have generated smoke plumes visible from space covering two million square kilometers.

Epicentre of the 6.3 magnitude earthquake that struck near the south coast of Japan's island of Honshu early Jul 28, 2019.
The estimated population of the area where the earthquake was felt is 30 million inhabitants, EMSC said.
There were no immediate reports of damage or injuries.

At this point, things are already so bad that many are calling for Governor Newsom "to declare a public health emergency"...
Pest control and public health experts are calling on California Gov. Gavin Newsom to declare a public health emergency over what they say is a sharp rise in the state's rodent population.
"California is being overrun by rodents - and without immediate emergency action by state and local government, we face significant economic costs and risk a public health crisis," said Carl DeMaio, chairman of Reform California, at a news conference Tuesday at City Hall in downtown Los Angeles.
On Thursday night, thousands of grasshoppers were seen swarming on the Las Vegas Strip. Thousands of people saw them the day after in videos that have now gone viral.
When a 13 Action News crew went back to the Strip on Friday, they found thousands of grasshoppers still in the same spots where they were seen on Thursday night.

According to NOAA, "23 of the 50 state record high temperatures were recorded during the 1930s," says Goreham. "Thirty-six of the 50 state record highs occurred prior to 1960."
But never mind such inconvenient facts.
Seventy-four US medical and public health groups released a "U.S. Call to Action" last month, in which they declared climate change to be a "true public health emergency." They also claimed that we urgently need to transition away from hydrocarbon energy and a move to a low-carbon economy.
"(Trouble is), "actual weather and health trends don't support either the alarm or the demanded actions."
On July 24 in Susuman was -4.1°C, the previous record of -3.5°C was observed in 1973.
In Seimtchane was -2.9°C, which is lower than the previous record by 0.5 degrees set 28 years ago.
In Brokhovo, the new absolute low for July 24 is +4°C, which is lower than the previous record by 0.6 for 1973.
In Talon -1.4°C, the former absolute low of -0.6°C was observed in the 1973.
Comment: With most media outlets exclusively and almost hysterically focused on the record-breaking hot temperatures being recorded this July, it's also of equal (or maybe greater?) significance that many new records are also being set at the other (cold) extreme, see these reports for the same month:
- Record cold in Hungary
- Record cold in Brazil
- Several record temperature lows in the Trans-Baikal territory, Russia
- "There is no heat out there" — Anomalous cold continues across Europe's Nordic nations
- Multiple all-time low temperature records set across Germany - Rare July frosts ravage Saxony
- New all-time July cold record in the Netherlands
- Temperatures sink to -6C in Southern Norway at the height of summer
- Russian city breaks 107-year-old cold record
- 15 cold weather records broken across Queensland, Australia
- Multiple all-time record low temperatures set in NW Russia
Two deaths each were reported from Darbhanga and Kishanganj districts, the state Disaster Management Department said in a release.
The total number of casualties in Darbhanga now stands at 12 and seven in Kishanganj.
Thirteen districts in the state are hit by the floods, which have affected 82.84 lakh people till date, the release stated.













Comment: The last 2 years or so has seen a notable number of these extralimital records of tropical seabirds in North America, presumably for the most part due to the increasingly chaotic weather, here's a list of such reports: Bird from the tropics, the brown booby, seen for first time in New Hampshire
Wrong place, wrong time: Tropical seabird turns up at Point Pelee, Ontario
Rare sighting of frigatebird in Wausau, Wisconsin, a likely hurricane refugee
Rare red-billed tropicbird turns up in Gulf Breeze, Florida
Wrong place, wrong time: Nazca Booby from the Galapagos Islands turns up at Dana Point, Califorina
Although displacement caused by severely adverse weather conditions seems the most plausible explanation in most cases, the following extract from a 2015 report of a brown booby turning up near Cape Race in Canada, indicates that at least some of these seabirds had been getting lost due to other factors:
