Nature's fireworks: Mexico's Popocatepetl volcano began spewing ash and glowing rock on Christmas morning
The 17,797-foot volcano is located just 45 miles southeast of the capital Mexico City.
The country's disaster prevention agency on Wednesday issued a level two 'yellow volcanic alert' stemming from more than two hours of tremors and gas emissions from Popocatepetl.
I don't know if such powerful bubbling is only a sign of an imminent eruption of it is an explosion itself:
In any cases, I wouldn't like living in one of those 'houses' in the vicinity of that Colombian mud volcano.
According to experts, this phenomenon is normal and occurs once a month, or every two to three months - they actually don't know.
The mud volcano is located in the Santa Fe de la Plata corregimiento and has had eruptions in 2006 and 2010.
Comment: A viewer of the video reports notes:
The reporter says that the outgassing is normal and happens once or twice every month or two, as it's been happening for the last 30 years or so, but that social media picked up the video and that's why it became news. He kind of protests too much, which I think it's because, as he says himself, it wouldn't be good for local tourism if people got worried and scared. He says that tourists were already bathing in there the same day, and that the event lasted for around a minute. That according to experts it's actually good that there is a regular release of gasses (he doesn't say why, but I assume it's because the accumulation of gasses could result in a much larger event). So nothing to worry about, he says.See also:

It is also one of the most active in the country, with the Volcanic Ash Advisory Centre (VAAC) based in the USA reporting constant activity at the site.
The last major eruption at Reventador took place in 2002, with a massive ash cloud of some 17-km-high reaching the capital and affecting some 2 million people.

Various underwater volcanoes were discussed at that time as the potential source. But direct proof for the exact origin of the pumice was missing so far. Researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany), together with colleagues from Canada and Australia, are now publishing evidence in the Journal of Volcanology and Geothermal Research that clearly identifies the culprit. It is a so far nameless underwater volcano just 50 kilometres northwest of the Tongan island of Vava'u. "In the international scientific literature, it appears so far only under the number 243091 or as Volcano F," says Dr. Philipp Brandl of GEOMAR, first author of the study.
A volcano erupted in New Zealand on Monday leaving at least one dead and seven tourists critically injured. Police said there could be more fatalities. 23 people have been transported to shore and over 27 remain on the island.
"We are working to confirm the numbers involved. At this stage, it is too dangerous for police and rescue services to go to the island. However, we continue to assess the conditions which would allow us to go onto the island", Police Deputy Commissioner John Tims said.
CEO of the New Zealand Cruise Association Kevin O'Sullivan confirmed that 30 to 38 of the victims are passengers of the cruise ship Ovation of the Seas.
The eruption began about 2:11 p.m. local time (0111 GMT) on White Island, about 50 kilometres from the east coast of North Island, authorities said, sending up smoke visible from the mainland.
Police is working with National Emergency Management Agency to coordinate the search and rescue operation.
Comment: Just a day earlier, New Zealand experienced a record in lighting strikes:
In the 24 hours leading up to 7am this morning, 109,000 lightning strikes were recorded over New Zealand and our surrounding waters, with 18,000 over the land.Update: New Zealand Herald reports:
Previously our records had only seen 44,000 strikes over both land and sea.
At least five people are dead after Whakaari/White Island erupted today, and "a number" of people are still unaccounted for.
National Operation Commander Deputy Commissioner John Tims told a press conference at 9.10pm that New Zealanders and tourists are involved.
A number of the tourists are from the Ovation of the Seas cruise ship, but police cannot confirm nationalities.
Police do not know if there are people on the island alive tonight. The five people dead are people who were taken off the island today. The other 18 rescued all have injuries to some degree.
Update Dec 10
RT reports:
Burn centers across New Zealand are full to capacity as more than two dozen victims are being treated for horrific wounds suffered in a volcanic eruption on White Island, leaving many with burns on over 70 percent of their bodies.
At least 27 of the 31 people injured in the volcanic blast that rocked the island on Monday suffered severe burns covering over two-thirds of their skin, the government said in a statement, noting the possibility that some of the injured will not survive.
"All our burns units are full to capacity. Our plastic surgeons, hospital, anesthetists are doing their best to treat the many who have sustained injuries," said acting Ministry of Health adviser Dr Pete Watson. "Twenty-seven of the 31 have suffered greater than 71 percent body surface burns."
With five already confirmed killed, police said eight people are still missing and likely did not make it, leaving only those who were able to flee immediately among the survivors.
"I would strongly suggest that there is no one that has survived on the island," New Zealand Deputy Commissioner John Tims told reporters, adding: "We are doing everything we can to get back to that island."
Tims also noted that a criminal probe had been opened into the disaster, focused on the "circumstances of death and injuries on White Island," which he said would be carried out alongside a separate investigation by regulatory agency WorkSafe.
Meanwhile less than a day after the volcanic eruption a strong 5.3-magnitude earthquake shook New Zealand's North Island.

The earthquake struck 25 kilometres south of Gisborne, but was felt across the island just one day after a deadly volcano eruption on White Island
The quake struck at a shallow depth of some 25km (15 miles) around Gisborne on Tuesday, about 150km (93 miles) south of the recently erupted submarine volcano on White Island.
While local news reports said the seism could be felt in neighboring towns - including Cambridge, Hunterville, Dannevirke and Wellington - there are currently no reports of damage or injuries, nor any danger of a tsunami, according to Gisborne Civil Defense Manager Wiremu Tamati.
Eruption warning for Russian city as volcano Avachinsky sitting on the Pacific ring of fire wakes up

Petropavlovsk-Kamchatsky city of 180,000 is just 26 km from 'waking' Avachinsky on Pacific's ring of fire.
Recent days have seen signs of activity on stratovolcano Avachinsky - 2,741 metres (8,993 ft) - prompting warnings to locals and tourists to stay away.
Vulcanarium website warned: 'Today, December 9, early in the morning, the first outbreaks were recorded in the crater of the volcano.
'Avacha has high gas contamination, you cannot get to the top.'

In total, "nine eruptions and eight explosions were detected between November 25 and 29 November 2019," according to VolcanoDiscovery.com.
The same report, which cites the Japanese Meteorological Agency, stated that the plume of smoke from the volcano reached 14,400-feet in altitude, resulting in a large amount of sulfur dioxide being released. The Japanese Meteorological Agency forecasted ashfall in the area on the same date.
The dramatic scene comes three weeks after the largest explosion at the volcano in three years.
