- Scarlet rains and vanishing wells are the setting for the monsoons this
time in Kerala. Yet, the phenomena have sent scientists scurrying around
- Ironically, instead of providing an explanation for the
curious happenings, scientists have thrown up more questions.
- After testing the red rainwater in Changanassery and
other places, scientists at the Centre for Earth Science Studies (CESS)
and Botanic Garden Research (TBGRI) labs have sought answers to four questions:
Is the explosive sound heard preceding the scarlet showers inter-linked?
What produced the huge quantity of spores (believed to have made rainwater
reddish)? How were the spores injected into the clouds? If the source is
local, how was the mass transported without getting distributed over a
- In fact, the CESS scientists have contradicted their
earlier explanation that the scarlet rains were caused by a meteor which
travelled from "east to west on the morning of July 25 and exploded
over Changanassery". They now say that the coloured rains were caused
- "The biological study conducted partly by the CESS
and partly by TBGRI detected red coloured cell structures, which tentatively
have been identified as the spores of some species of fungus," said
CESS Director M Baba.
- The latest inference is that the coloured rains are a
mystery although they have been reports of similar occurrences in other
parts of the world.
- The scientists have also rejected reports that the rain
was accompanied by thunder and lightning. "Lightning does not occur
during the southwest monsoons. Lightning is produced from large cumulonimbus
clouds which develop only when plenty of humid air is available on the
earth's surface. The conditions at the time were not suitable for this.
Secondly, people over a radius of around only 1.5 km heard the sound. This
is highly improbable," said Baba.
- "Therefore, the only possibility is that the sound
was actually a sonic boom produced by some object moving at supersonic
speed at a relatively low altitude. Since no aircraft is expected to fly
at supersonic speeds close to the ground, it is opined that a meteor had
approached the area and possibly exploded to produce red colour rain,"
the CESS director said, expanding on the earlier "meteor theory".
- Scientists are also divided on why scores of wells have
reportedly been damaged or disappeared and new ones suddenly sprung up.
According to one school of thought, these are a warning for impending earthquakes.
Others, however, believe that they are a result of underground water pressure
and heavy rains.
- Similarly, the sudden shrivelling up of leaves in some
areas is puzzling the scientists.
- Meanwhile, Kerala chief minister A K Antony has asked
people to await the results of the scientific probes.

- THIRUVANANTHAPURAM: Even as scientists are yet to reach
any definite conclusion about the cause of the 'red rain' and caving in
of wells in Kerala, stranger phenomena like sudden formation of wells and
unusual falling of leaves of plants and trees have been reported from the
- In the last couple of months about 175 cases of "well
collpase" have been recorded from across the state, baffling the people
and experts alike.
- In what could be the exact opposite, two cases of natural
well-formation have been reported from Kasargode and Thrissur districts,
creating panic among the people.
- Villagers of Vellimon in Kollam were witness to a strange
spectacle when leaves of plants and trees in half-a-hectare stretch suddenly
started falling in strong wind and drizzle in the morning.
- The mystery over `scarlet rain', experienced in parts
of central Kerala recently, deepened further as experts from the Centre
for Earth Science Studies (CESS), distanced themselves from their earlier
hypothesis that the phenonmenon could have been caused by dust thrown off
by a meteor burst.
- They claimed on Saturday that the sample analysis of
coloured rain showed the presence of fungal spores.
- By its own admission, the "tentative conclusions"
leave unanswered questions like what could have produced the huge quantity
of spores and how they got injected into the clouds.
- The chemical analyses of the samples showed the presence
of carbon, silicon, calcium, magnesium, aluminum, iron, sodium and pottassium
besides significant trace quantities (in parts per million) of phosphurus,
titanium, chromium, manganese, copper and nickel.
- The CESS has discounted the possibility of the well-collapse
having any link with seismic activity as feared by the people.
- "Bad construction of wells coupled with hydrographic
pressures caused by above-normal rains" were cited as main reasons
for the well-collapse.
- Taking the general apprehension into account, the state
government had, however, sought central help for an in-depth examination
of the phenomenon.
- The people of Arimbur village were taken by surprise
when land slipped and a well emerged at the courtyard of one Thanikkal
Jose on Saturday. The well is 22 ft deep with muddy water at the bottom.
- A similar case has been reported from the homestead of
one Sivadas of Kumbala in Kasargode district.
- What apparently makes people apprehensive is that many
parts of the state experienced mild tremors last year. Before and after
the tremors, unusual waves were found in wells in some places, which experts
termed as a phenomenon called 'seismic seiches' which has nothing to do
with an impending earthquake.

- THIRUVANANTHAPURAM, AUGUST 5: The red rain that lashed
parts of Kerala last month is eluding explanations as the days go by.
- The Centre for Earth Science Studies (CESS) here on Saturday
retracted its hypothesis that a streaking meteor triggered the rain.
- Everybody had taken that explanation with a pinch of
salt because other researchers had spoken of biological contents in the
water samples. Yet, the retraction has raised eyebrows about a premier
research bodyâs prudence in making a hurried announcement.
- CESS has not only retracted, but tagged a confession:
ÎÎThis leaves several questions unanswered.ââ The
CESS press release was triggered by the chemical analysis of the water
samples that showed these were largely biological. Biological studies have
identified organic material such as fungal spores in them.
- CESS director M. Baba said: ÎÎThe exact species
is yet to be identified. But how such a large quantity of spores could
appear over a small region is as yet unknown.ââ
- On July 25, Changanacherry town had received the coloured
showers overnight that continued into the morning and on till sunset. Some
residents collected samples of the rain. They said the shower was accompanied
by thunder and lightning.
- CESS then collected the samples and tested them. The
water was found to be neutral and contained some amount of dissolved salts.
- The filtered precipitate was fine and powdery, and this,
said Baba, was chemically and biologically analysed.
- The chemical analysis showed various elements ÷
including carbon, silicon, calcium, magnesium, aluminum, iron, sodium and
potassium. It contained significant traces (in parts per million) of phosphorus,
titanium, chromium, manganese, copper and nickel.
- The biological study ÷ partly conducted at CESS
and at the Tropical Botanic Garden and Research Institute (TBGRI), Pacha
Palode ÷ revealed a red coloured cell structure.
- This has been tentatively identified as spores of some
fungus species and are now being cultured by the TBGRI. ÎÎThe
red colour of the rain appears to be mainly because of the spores,ââ
- These findings, say CESS, raise doubts on whether the
explosive sound reported by residents and the red rain were independent
events. There are other posers too which remain unanswered:
- What produced the huge quantity of spores ? Is the source
local or distant?
- How were the spores injected into the clouds?
- If the source is not local, how was the mass transported
without getting distributed over a large area?
- By way of an answer, CESS has only this to say : ÎÎWhile
the cause of the colour in the rainfall has been identified, finding the
answers to these questions is a challenge.ââ
