El Rodeo, Guatemala (CNN) Ovidio García Suárez was born and raised in the shadow of Guatemala's Fuego volcano. He has lived through plenty of volcanic activity in his 64 years, he says -- but nothing like this. 
 
 On Sunday, Fuego unleashed a fast-moving mix of ash, rock and volcanic gases that virtually swallowed San Miguel Los Lotes, the neighborhood in El Rodeo where García lives, transforming the landscape into a gray wasteland. 
 
 Homes are buried in ash, some of it still hot to the touch. Leaden clothes hang on clotheslines. An eery silence hangs in the air, apart from the presence of chickens that somehow managed to survive the explosion. 
 
 Volcanic rocks the size of baseballs and larger litter the ground. Melted car tires lay in puddles of rubber and twisted steel. 
 
 At least 99 have died from Fuego's fury, and 192 are missing -- including García's wife. 
 
 García was away from his home when Fuego exploded and his daughter called him. "Mom disappeared," she told him. His son's wife was in the home, too, and they don't know where she is, either. Their home was destroyed. 
 
 "Now there is nothing," he says. "What's the government going to do?" 
 
 'It's dangerous, but we go anyway' 
 
 At least 192 people are missing, Guatemala's disaster relief agency said, and rescuers face hazardous conditions as they navigate hot, rocky debris. And Fuego might not be done yet. It expelled more rock and gas Tuesday, sending ash over 16,000 feet into the sky and temporarily halting search operations.

 More pyroclastic flow -- the name for the nasty mix of ash, rock and volcanic gases -- is possible in coming days, the country's disaster relief agency said. 
 
 Despite the circumstances, firefighter Rigoberto Ramirez remained hopeful that more survivors will be found in El Rodeo. Near El Rodeo, searchers found signs of rushed attempts at flight. A red truck full of possessions, including a refrigerator, rests abandoned, its tires melted to the ground. 
 
 An abandoned car rests atop debris Wednesday in El Rodeo, Guatemala, after the volcano's eruption. 
 
 Smoke rose from the volcano Wednesday morning, and Ramirez's colleagues parked their vehicles facing downhill in case Fuego erupted again and they had to make a quick exit. 
 
 "There's hope," he said. "But it's dangerous for us to go up there. Water has been trapped under the ash and vapors could come out any time." 
 
 "It's dangerous, but we go anyway." 
 
 Rescue workers search Tuesday in El Rodeo. 
 
 'We were covered in ashes' 
 
 The eruption of Volcan de Fuego, which means fire volcano, was visible from space; satellite footage showed a massive, dark gray ash cloud. More than 12,000 people have been evacuated. 
 
 Near San Miguel Los Lotes, Miriam Juarez and her husband, Jose Amigar, waited Wednesday near a cordoned area, hoping authorities would let them pass so they could retrieve some belongings. 
 
 They said they ran Sunday after one of their children urged them to flee. By the time they reached a shelter in the city of Escuintla, "we were covered in ashes," Juarez said. 
 
 "It was this dark smoke, very dark and it just got bigger," Juarez recalled. 
 
 The couple is staying with their four children at the shelter. Frustration was building Wednesday as officials still wouldn't let the couple go near their home of more than 25 years.

 "It's our house ... and they won't let us up there," Amigar said, with tears in his eyes. "They say it's for our safety, but they never cared when we lived there." 
 
 Others anxiously await news of their loved ones. Eva Ascón -- from Guatemala City, some 25 miles away the volcano -- seemed to accept that her relatives who lived near the eruption did not survive. 
 
 Ascón told reporters Tuesday she would ask rescue workers to "give us time to identify the bodies in the morgue; don't take them away as unidentified." 
 
 "Even if there are only small bones of my people, I want them," she said. "I don't have even one member of my family." 
 
 Injured children to be treated in the US 
 
 Twelve people severely wounded since the eruption will receive medical attention in the United States and Mexico, Guatemalan President Jimmy Morales said. 
 
 Six children will be treated for severe burns at Shriners Hospitals for Children in Galveston, Texas, the hospital said. 
 
 The children will fly to Texas aboard a US Air Force plane by late Wednesday, Guatemalan and hospital officials said. 
 
 An emergency medical team from the hospital has been treating the injured on the ground after being deployed Monday to Guatemala, it said. 
 
 Six other patients will be transferred to Mexico, Morales said. ||||| Media playback is unsupported on your device Media caption Guatemala volcano: Thousands evacuated 
 
 At least 192 people are missing and 75 are dead as a result of the explosion of the Fuego volcano in Guatemala on Sunday, officials say. 
 
 Villages on the slopes were buried in volcanic ash and mud. 
 
 Rescue work on Tuesday was disrupted when a new eruption sent hot gas and molten rock streaming down the volcano's south side. 
 
 More than 1.7 million people have been affected by Sunday's eruption, with more than 3,000 evacuated. 
 
 Tuesday's explosion took many by surprise after volcanologists said the eruption, which had sent ash up to 10km (33,000ft) into the sky on Sunday, was over for the near future. 
 
 Eddy Sanchez, the head of Guatemala's National Institute of Seismology, had predicted "no imminent eruption over the next few days". 
 
 A village wiped off the map 
 
 Will Grant, BBC News, El Rodeo, Guatemala 
 
 Boris Rodriguez has no-one to turn to now. He lost more loved ones in a single night on Sunday than many do in a lifetime. 
 
 Mr Rodriguez's wife, both of her parents, his brother and sister-in-law and their children died when the Fuego volcano erupted. 
 
 "I saw the children's bodies," he told me between sobs. "They were huddled together in the bed, like they were trying to hide from what was happening." 
 
 If Mr Rodriguez, who is 25, were a solitary case, it would be heartbreaking enough. But most of his neighbours in the village of El Rodeo have similar stories of grief. The village was almost entirely wiped off the map. 
 
 Chaos and hope: More on-the-ground accounts

 Why were so many people killed in the initial eruption? 
 
 Almost 200 people remain unaccounted for, said AFP news agency, quoting Guatemala's Disaster Relief Agency. 
 
 No evacuation alert was issued before the volcano erupted on Sunday, said the agency's chief, Sergio Cabañas. 
 
 He added that local residents had received training in emergency procedures but were not able to implement them because the initial volcanic activity happened too fast.

 Sunday's blast generated pyroclastic flows - fast-moving mixtures of very hot gas and volcanic matter - which descended down the slopes, engulfing communities including El Rodeo and San Miguel Los Lotes. 
 
 Volcanologist Dr Janine Krippner told the BBC that people should not underestimate the risk from pyroclastic flows and volcanic mudflows, known as lahars. 
 
 "Fuego is a very active volcano. It has deposited quite a bit of loose volcanic material and it is also in a rain-heavy area, so when heavy rains hit the volcano that is going to be washing the deposits away into these mudflows which carry a lot of debris and rock. 
 
 "They are extremely dangerous and deadly as well."

 Deadly flow, as fast as a jet plane

 A pyroclastic flow is a fast-moving mixture of gas and volcanic material, such as pumice and ash. Such flows are a common outcome of explosive volcanic eruptions, like the Fuego event, and are extremely dangerous to populations living downrange. 
 
 Just why they are so threatening can be seen from some of the eyewitness videos on YouTube of the Guatemalan eruption. In one, people stand on a bridge filming the ominous mass of gas and volcanic debris as it expands from Fuego. 
 
 Some bystanders only realise how fast it is travelling as the flow is almost upon them.

 The speed it travels depends on several factors, such as the output rate of the volcano and the gradient of its slope. But they have been known to reach speeds of up to 700km/h - close to the cruising speed of a long-distance commercial passenger aircraft. 
 
 In addition, the gas and rock within a flow are heated to extreme temperatures, ranging between 200C and 700C. If you're directly in its path, there is little chance of escape. 
 
 The eruption of Vesuvius, in Italy, in 79 AD produced a powerful pyroclastic flow, burying the Roman towns of Pompeii and Herculaneum under a thick blanket of ash.

 Guatemala's most violent volcanic eruption in more than a century has killed 62 people, officials say. 
 
 Dozens more are missing, the country's disaster agency says, and it is feared the death toll could rise. 
 
 Villages on the slopes of Fuego volcano were buried in volcanic ash, mud and rocks during Sunday's 16-hour eruption. 
 
 Pyroclastic flows, which are fast-moving mixtures of very hot gas and volcanic matter, rushed down the mountainside and engulfed villages. 
 
 President Jimmy Morales has declared three days of national mourning. 
 
 A further pyroclastic flow on Monday sparked alarm. 
 
 Guatemala's coast has also been hit by an earthquake though there are no reports of damage so far. 
 
 What has happened? 
 
 Fuego, about 40km (25 miles) south-west of the capital Guatemala City, spewed rock, gas and ash into the sky. 
 
 Fast-moving flows hit villages, killing people inside their homes.

 Sergio Cabañas, head of the country's National Disaster Management Agency (Conred), said the town of El Rodeo had been "buried". 
 
 Other towns affected include Alotenango and San Miguel Los Lotes. Rescuers are still trying to reach a number of villages. 
 
 Temporary shelters have been set up for about 3,000 residents who have been evacuated.

 Efrain Gonzalez, who fled El Rodeo with his wife and one-year-old daughter, said he had had to leave behind his two older children, aged four and ten, trapped in the family home. 
 
 Local resident Ricardo Reyes was forced to abandon his home: "The only thing we could do was run with my family and we left our possessions in the house. Now that all the danger has passed, I came to see how our house was - everything is a disaster."

 About 1.7 million people have been affected in four regions. The country's main airport has now reopened. 
 
 Officials have advised people to wear masks as protection against falling ash. 
 
 How exceptional was the eruption? 
 
 Fuego is one of Latin America's most active volcanoes. A major eruption devastated nearby farms in 1974, but no deaths were recorded. 
 
 Another eruption in February this year sent ash 1.7km (1.1 mile) into the sky. 
 
 Sunday's event was on a much greater scale. 
 
 This eruption is one of Guatemala's deadliest such events since 1902, when an eruption of the Santa Maria volcano killed thousands of people. 
 
 Guatemala's national institute of volcanology, Insivumeh, told people to keep away from the affected ravines as there is a possibility of "a reactivation". 
 
 The institute also warned of the possibility of lahars - when water mixes with volcanic deposits forming a destructive debris flow - which could affect villages and hamlets to the south, south-west and south-east.

 Eyewitness account: 'Day turned into night' 
 
 From Jorge Luis Altuve, member of Guatemala's mountain rescue brigade 
 
 A team of about 40 of us from mountain rescue were up on the volcano searching for a person who had gone missing last week. 
 
 We'd located the body of the missing person and were going to retrieve it when the activity of the volcano increased quite suddenly. We were at a height of about 3,700m (12,000ft) and not far from the crater when we decided to abort the operation and descend. 
 
 At first, we thought it had started to rain but then I heard something hitting my safety helmet and I said to one of my colleagues: "This is not rain, these are stones!" 
 
 The stones raining down on us started getting bigger and bigger. Some were as big as 5cm (2in) in diameter. We'd already started our descent from the mountain when the ash cloud reached us and day turned into night. 
 
 Image copyright Reuters Image caption This police officer stumbled as he ran through pyroclastic deposits on Monday 
 
 From daylight it went to being as dark as at 10pm. Luckily we were carrying all of our equipment which includes torches and helmets and we also know the volcano very well. 
 
 We started to move a lot more quickly. We were also in constant communication with our colleagues at the mountain rescue command post and they kept telling us: "Get out of there! Get down, quick!" 
 
 In total it took us three or four hours to reach the command post. Luckily we got away unscathed, just with some bruises from the falling stones. 
 
 This really came as a surprise, there had been no alert when we'd set out to search for this missing person. 
 
 We only really realised the magnitude of this when we got back down and saw everything covered in ash and bridges destroyed.
– At least 75 people are now confirmed dead in the eruption of Guatemala's "Volcano of Fire" and authorities fear the true death toll could be in the hundreds. At least 192 people are missing and one village, El Rodeo, has been almost completely wiped off the map by a river of lava, the BBC reports. Rescue work was badly disrupted Tuesday when strong explosions sent fresh ash, rock, and gases streaming down the Fuego volcano, which is around 25 miles away from Guatemala City, reports CNN. Authorities say only 23 victims have been identified so far, including two young girls, ages 3 and 6. Around 3,000 people have been evacuated and the US Air Force is taking six badly burned children to Texas for treatment. In the village of Escuintla, survivor Lilian Hernandez listed no fewer than 36 missing family members, the AP reports. "My cousins Ingrid, Yomira, Paola, Jennifer, Michael, Andrea, and Silvia, who was just 2 years old," the distraught woman said. In El Rodeo, rescuers dug through ash-covered homes and found one sign of life: A dog that somehow survived in a home where four people died. "Animals have a different sort of resistance ... and different behavior when it comes to finding refuge," says Julio Sanchez, a spokesman for the country's disaster agency.
