I ran across these tips for survival planning, assuming we had warning 10 years ahead of a mega-volcano eruption (Yellowstone in this case). Some of the tips are pretty good and a few are doable to some degree by most people. This is taken from Quora.

The biggest effect of a supervolcano eruption would be “volcanic winter”. Crops would fail worldwide and there would be gigadeath by starvation as a result. With ten years to plan, however, we could do a number of things to preserve humanity:

The biggest effect of a supervolcano eruption would be “volcanic winter”. Crops would fail worldwide and there would be gigadeath by starvation as a result. With ten years to plan, however, we could do a number of things to preserve humanity:
- Push agriculture into maximum production now and start saving food to feed the masses. This is probably not enough since we won’t really know how bad the volcanic winter will be until it is upon us, so we also have to . . .
- . . . start building better nuclear reactors* outside of the heavy ash zone to provide electricity and heat to adjacent, massive greenhouses, and start building those greenhouses. And build more of those reactors to desalinate seawater for use in those greenhouses and for people.
- Start moving non-essential production facilities out of the way of the worst of the volcanic ash.
- Build shelters and businesses out of the ash zone to take care of the people displaced by the eruption.
- Build “Noah’s Ark” for real (except it doesn’t have to be a boat).
- Build all new buildings with roofs steep and slippery enough so that volcanic ash just slides off, and add such roofs to existing buildings. This will prevent the collapse of buildings under the weight of volcanic ash.
- Stock up on reusable, ash-proof breathing gear and attire. Start modifying vehicles to be able to work with ash blowing around.
- Grow a whole lot of seed for ground cover plants which will grow in volcanic ash. The sooner we nail that junk down the better.

REVOSIMA's update on November 30, 2019, showed the continuous seismo-volcanic activity at a newly-forming submarine volcano near Mayotte island from October 16 to 30, including 186 localized earthquakes and an average of 12 tremors per day-- one of which was M3 or greater, with a magnitude of 3.8.
The fissure has been causing crisis ever since earthquake swarms were felt in May 2018. The source was confirmed to be a new underwater volcano in May 2019. On November 21, 2019, it was discovered that the incessant eruptions may contaminate Petite Terre's Lake Dziani.
Over a period of 11 months from July 2018-- the start of surface deformations in Mayotte-- to June 2019, the eruptive lava flow is around 150 to 200 cubic meters per second.
Since the volcanic edifice was discovered, three new remote exit points have been discerned that have produced the following: about 0.2 km3 (0.05 mi3) of lava in 28 days from May to June 2018 for an average minimum flow of about 83 m3 per second (2 930 ft3) in the south; about 0.3 km3 (0.07 mi3) of lava in 44 days between June to July 2019 for an average minimum flow of 79 m3 (2 790 ft3) per second in the west; and about 0.08 km3 (0.02 mi3) of lava in 20 days between July and August 2019 for an average minimum flow of about 44 m3 (1 553 ft3) per second in the north.
The eruptive flows remain high, and the volumes and flows, particularly at the start of the crisis, are unusual. Given the unpredictability, they are generally the highest observed on an effusive volcano since the 1783 Laki explosion in Iceland, whose average eruptive flow had been calculated approximately 694 m3 (24 500 ft3) per second over 245 days of the eruption.
The vectors of horizontal displacements since August 2019 point more towards the north. This resulted in a relative displacement of the simple isotropic pressure source, about 20 to 25 km (12 to 15 miles) more to the northwest, compared to the start of the year. Experts have then formulated several hypotheses.
For the past three months, the best single model that can be responsible for these displacements would be a source of localized deflation between 26 and 73 km (16 and 45 miles) east of Mayotte, and a depth between 45 and 75 km (28 and 47 miles) at 95% probability.
The flows associated with the best models over the last 15 days would be between -30 to -80 cubic meters per second.

"Note that in the case of a source in deflation, the evolutions of [the] position of the source towards more superficial depths do not translate a source migration but could be linked to the effect of the closure of a conduit, being gradually from the bottom up," according to the bulletin.
"More complex models, under evaluation, suggest that several sources of pressure (in deflation and inflation), geometry and variable volume, located at different depths, could also explain the deformations observed over different periods of time."
The dominant source, nevertheless, remains a source of deflation and such confirm that transfers of magmatic fluids are still ongoing in-depth and they seem to circulate between 20 to 60 km (12 to 37 miles) deep.

Prediction of Volcanic Eruptions
To give people advance warning that a volcano is going to erupt, engineers and scientists are creative in designing and building devices to detect natural indicators of volcanic eruptions. Warning signs include earthquakes, gas emissions, change in magnetic field, and the swelling of the volcano itself. To monitor active volcanoes, seismometers detect the vibration of earthquakes, tilt meters detect even slight changes in the shape of the mountain (see Figure 10), and other devices monitor and measure escaping gases. Students can use the associated activity Ready to Erupt! to learn the important phases of an erruption to help predict disasters!

Hmm, gonna have to look up some charts on the GSM.
Before being blasted off the face of the earth 66 million years ago by a city-sized asteroid that evidence suggests hit the Gulf of Mexico with the impact of 10 billion WWII-era atomic bombs, a more insidious fate may've befallen dinosaurs: They may've been poisoned. A study published this week in the journal Nature Communications suggests potential mercury poisoning of the Cretaceous monsters, based on analysis of marine mollusk fossils.
While human-generated sources of mercury include coal-fired power plants and gold mines, the largest natural sources of mercury entering the atmosphere are volcanoes, which were the University of Michigan researchers' focus. Massive volcanic eruptions in India -- known as the Deccan Traps eruptions, which lasted for nearly a million years -- contributed to both rapid ocean warming and elevated toxic mercury levels around the world during the time of the dinosaurs. When the researchers compared mercury levels from the fossils to those gathered in a present-day Shenandoah Valley site of industrial mercury pollution, the levels were roughly equivalent.
"For the first time, we can provide insights into the distinct climatic and environmental impacts of Deccan Traps volcanism by analyzing a single material," the study's lead author, Kyle Meyer, said in a release. "It was incredibly surprising to see that the exact same samples where marine temperatures showed an abrupt warming signal also exhibited the highest mercury concentrations, and that these concentrations were of similar magnitude to a site of significant modern industrial mercury contamination."
The scientists said that Mercury anomalies have been documented in sediments before, but never in shells. So the new technique could help further the study of mass extinctions and climate shake-ups in the geological record.

Strange sounds is reporting that there's been "strong" activity at Arboletes mud volcano in Colombia. News reports are provided but I don't speak Spanish, so i can't undersand from the footage whether this is unusual activity or not. Considering they are reporting on it, i presume it is? Then again, they also note that this "phenomenon occurs once a month" or so, but that they also don't really know how common it is...Video in the article below:
Strong Degassing at Arboletes Mud Volcano in Colombia
By
Strange Sounds
On December 19, 2019, unusual activity was recorded at Arboletes mud volcano in Colombia.
Some powerful degassing occurred in the middle of the crater sending bubbles of gas to the surface.
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.
The volcano forms a dome of 600 meters in diameter for a height of 8-10 meters, with two summit mouths, with respective dimensions of 50-60 meters and 3 meters in diameter. It’s a very well-known tourist destination for the medicinal benefits of its mud, which allows people to float and swim on the surface. Continue reading Strange Sounds or visit Steve Quayle.
Strong degassing at Arboletes mud volcano in Colombia video - Strange Sounds
Strong degassing has been witnessed by locals at Arboletes mud volcano in Colombia with giant bubbles exploding at the surface of the mud.strangesounds.org
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.
Mexican authorities issued a ‘level 2’ yellow alert.

WATCH: Mexico issues yellow alert after Popocatepetl volcano erupts spectacularly
One of Mexico’s most active volcanoes, Popocatepetl, erupted on Thursday morning, spewing ash high into the air above and showering lava around its crater. Officials have issued a yellow alert in response to the volcanic activity.
Again?... did not even knew when authorities decrease to level 1(??)
Anyways, CENAPRED (Centro Nacional de Prevención de Desastres, volcano monitoring organization among other issues. National Centre for Disaster Prevention (in English) post this tweet ...
#CENAPRED reports on the activity of #Popocatepetl.
At 06:33 h, an explosion with moderate ash content was detected. The column was 3 km high, heading northeast.
El
de alert is in #AmarilloFase2. Urged not to approach the volcano.But, there is other data
