These are not some ghosts seen by occasional people and questioned by majority. Ghost fireballs of Mekong have been seen by thousands of people, photographed and captioned on movies and, after all, investigated by scientists looking for the explanation of this interesting phenomenon.
Fireballs are observed in some 250 kilometres long sector of Mekong: approximately from Ban Muang upstreams from Vientiane down to Bung Kan. Most of them rise from the 500 – 800 m wide Mekong River, but they have been observed rising from smaller ponds and rivers as well. These places might sound exotic and remote to Europeans but they are densely populated, filled with houses, roads, schools and other usual features of civilisation.
Phenomenon of Naga fireballs is not too well documented in earlier times. Some say that Wat Luang temple (in Phon Phisai, Wat Pho Luang Phra Sai) contains centuries old written records mentioning them. There are mentioned also occasional written reports from British soldiers in the 1960s – although nothing concrete is cited. Numerous local people claim that they have seen the lights for all their life and their parents and grandparents did it as well.
Although the appearance of fireballs is celebrated at certain days in October, in fact this event is not predictable. There have been cases when the official festivity "ends without results" and fireballs come unexpected in another night. Many people have tried hard to see them for years without success, many are lucky and see them at first visit to this site. For example, in 2001 there were reported 3,000 fireballs, the festivity of 2004 was disappointing in this respect but in 2008 the illumination was excellent.
Ghostly fireballs can be seen in different times of the year but most frequent they are in late October – early November, when the long period of rains has ended and Mekong is filled with lots of fast flowing, muddy water.
Balls seem to be rising out of the water (some sceptics though say that it looks more like going up in Laotian side of river). They appear in different places, but sometimes several come out from single place.
Phaya Naga – king of serpents
Since ancient times numerous people have been living along Mekong. According to some reports, as recently as in the 1980s these balls of light attracted little attention of local people (3). It may be though possible that there are some ancient myths related to this event which later have been nearly forgotten by local people and then somehow revived.
Whatever the history of this myth but one is clear – since the early 1990s Mekong fireballs gradually became famous and simultaneously there were attached myths to them. One of these myths:
One particular naga (a kind of snake or dragon) loved to crawl around the mountains right in the place where Mekong flows today. This outstanding naga still continues to travel her usual route – now underwater, and spits flames wherewer it goes – as all respectable dragons do.
There is involved also Buddhism into this story, making it more complex – although local Buddhist monks seem to be spectators of show and not active promoters of it. This "Buddhist" myth has involved the ominous Phaya Naga – serpent-king of underworld – in making of these fireballs. Phaya Naga in this story turns out to be an ally of Buddha. Buddha and Phaya Naga in their mythical battles obtained a blessing for local people – regular periods of rain. As the rain ends, Buddha returns to Earth from heaven and Phaya Naga greets him with fireballs.
There is traditional and well proven method to facilitate tourism anywhere in world, which works especially well in southern Asia: if your locality happens to have some interesting natural phenomenon, find a religious explanation to this and organise yearly festivities to celebrate it.
In a case of Phon Phisai town in Thailand (and several other towns along Mekong) naga fireballs have been perfectly well suited. Fireballs are most frequent in the end of October – thus exactly then is organised the religious Phaya Naga festival.
This coincides very well with an important event in Buddhist calendar – the end of vassa: three months long period of a kind of fasting. The end of vassa – Wan Awk Pansa – is joyous festivity of the people of Isan (North-east Thailand) and Laos. This festivity in a way marks the end of long rain period. Staying out in the evening after the long rains finally is pleasant and moon over the Mekong makes this time romantic.
Festivity is organized at full moon. Somehow the determination of full moon has ended up with a situation where Thailand celebrates the festivity one day earlier than Laos. Lately though the festivity is expanding and lasts for several days and nights.
According to locals, festivities have taken place here for many generations – but if there were any festivities before 1990, these were of truly local nature, not known elsewhere. But in the early 2000s the festivity at Mekong came into vogue.
Thus, at the end of every October tens of thousands of people flock to Phon Phisai and other Thai and Laotian towns along Mekong. In 2002 – 2004 there were hundreds of thousands of people coming. They take the "best places" along the river.
Earlier people just walked at the bank of Mekong and looked at occasional fireballs rising up. Nowadays there is organised festive program with the great Mekong in focus: in the river are floating beautiful illuminated boat processions and river receives offerings – mainly sweets. Numerous other events take place, as it is ususal in popular festivals.
But the main event is the appearance of fireballs. Thousands of people look with awe at them rising up in the air as fast as sparks from the campfire. In some nights thousands of such weird sparks rise out from the waters but sometimes – none. People cheer the lights with joy and feel happy to be together at this mystery.
Scientists get involved
Contrary to most of the other ghostly apparitions around the world, Naga fireballs have been observed by thousands of people and captured on numerous photographs and movies.
Most local people believe in the mythical explanation involving nagas. In 2002 there arised a scandal when independent Thai TV channel iTV reported that they observed the following: each time when Laotian soldiers shot some tracer bullets in the air, Thai side of river was greeting this with cheerful shouts. TV reporters thus proved that sometimes "fake" naga balls are greeted.
This report met with stiff resistance of local people expressing even hate towards iTV.
Government of Thailand decided that scientists should be involved and explanation should be provided. A kind of "dreamteam" of Thai experts was established, at the same time rising heated debates about the intrusion of science in traditional myths.
In 2003 thermal scanners and five teams of scientists were stationed in several spots along the river in Rattanawapi district (Thailand). A team was located also at the most famous observation spot – at the Naga temple in Phon Phisai town. There were rumours about the involvement of specific submarine in research.
Some scientific reports mention an upward movement of gas bubbles in Mekong water. According to them – as the gas bubbles reached the surface, the gas started to burn and rised up like a glowing orange bubble.
Earlier some scientists considered that the most likely reason for flames is phosphine (PH3). This gas, especially in the presence of the diphosphine (P2H4), is capable of spontaneous flammability. Thus one can assume that bubbles of this substance may rise from the sediments of Mekong and, as it reaches the atmosphere, burn with yellow – orange flame. Small amount of this substance quickly is consumed in flames, and, as the burning bubble rises up in the air, it disappears.
Possible source of phosphine might be a chemical reaction in the river sediments – bacterial reduction of phosphate in decaying organic matter.
Often is mentioned another gas – methane, which, theoretically, if mixed with the same phosphine and some other gases at very specific conditions may experience spontaneous ignition.
There remained unsolved issues though:
- Phosphine is not a light gas, it is heavier than air. Naga lights though rise up in the air very quickly.
- When phosphine burns, it produces dense, white and highly toxic cloud. None of these effects (luckily) have been observed on Mekong.
Thus the hypothesis of phosphine is rejected and specialists focus more on other self-inflating gases: burning gas seems to be the most logical explanation for Mekong fireballs. But – even if scientists find another igneous gas rising from the sediments of Mekong – why don’t we observe similar phenomenon elsewhere – in other tropical rivers and lakes? How can a bubble of gas rise up that quickly without being extinguished?
Some consider that these igneous gases are somehow pulled out of the river sediment by full moon and some researchers even build up highly complex theories involving specific composition of gases in sediments coupled with the action of moon, ultraviolet rays, Sun etc. All of this at the end looks too laborious and unlikely.
Also the imaginary organic sediments of Mekong seem not to exist – river here for most part has sandy bed with occasional rocks.
Popular Thai movie "15 Kham Duan 11" ("The 15th of the 11th Lunar Month", made in 2002) offers another explanation – here Laotian monks place clay eggs on the river bed – these rise to the surface and there light up. There are though serious drawbacks in this fine movie, which seem to make this proposed explanation flawed (if art is taken seriously): more or less safe and controlled diving in this muddy, powerful river is nearly impossible even with modern diving gear.
Often it is considered that fireballs are created artificially – just like some people find fun in making crop circles or other weird things. Now it is essential to keep the big festivities running – after all this event has been turned into highly profitable show (but spread among huge local communities – what isn’t bad at all). One can easily see that there might be a commercial interest to "maintain" this phenomenon artificially.
In addition to this – some locals tell that in earlier times naga fireballs were much smaller and nearly white, they rised above the water just for a few metres. Now, with increased popularity they somehow have evolved, increased in size, fly high and fast and have orange color. A bit heretical thought – may be naga serpent has changed diet?
Hoax is impossible?
Locals deny a possibility of hoax – naga fireballs often are observed in very secluded places where the putative "organiser" of fireballs has nearly no chances to impress anyone. It is just weird to imagine countless Thai and Laotian people keeping themselves busy by making illuminations in remote lakes and rivers.
Appearance of fireballs has been reported in more than 45 kilometres long section of river in one night. River has been closely watched by numerous people for many days before. In such circumstances the possibility of fraud seems to be quite low – who would manage to organise such illumination without getting caught in the act?
Naga fireballs rised from the river during the hostilities between Thailand and Laos: the border was heavily guarded then and it is little likely that somebody would risk his life to organise the fraud.
Legend of modern times
Wondermondo will not present a judgement about the source of naga balls. One though should be recognized – if this is a hoax, it is organised very well and there are lots of people who are happy to believe in this.
But may be naga fireballs are real, natural mysterious light effects – so called Earth lights (see another example – Chir Batti)? Riddles posed by these phenomena are not that easy to solve.

Similar phenomena described by Wondermondo
- Hessdalen lights in Norway are balls of light often seen floating in Hessdalen valley. This phenomenon has been researched since 1983 but no explanation has been found thus far.
- Chir Batti in India, Gujarat are balls of light floating near the ground level around the plains of Banni grasslands. These lights were noticed here already in ancient times. There is no scientific explanation to this phenomenon.
- Paasselkä devils in Finland are light balls of unexplained origin. They are observed over the surface of Lake Paasselkä for at least 100 years.

Although Thailand is tourist hotspot, most foreign tourists come to this beautiful country to relax and thus: to prepare for another stressful year of work and daily worries. Natural and cultural heritage of Thailand though offers a lot more.
Only in recent years Laos is emerging on the stage of international tourism – this beautiful country for decades was dragged in terrible wars and post-war isolation period.
There are not too many landmarks in this category – but several of them are highly unusual and unique.
