Earthquake Lights (EQL) –
What are Earthquake Lights (EQL)?
Rare luminous atmospheric phenomena seen:
Before earthquakes
During earthquakes
After earthquakes
Earlier considered:
Myths
UFO sightings
Now recognized by:
United States Geological Survey
NASA
Called:
Co-seismic optical events
Pre-seismic optical events
Formation Mechanism (Flowchart)
1. Tectonic Stress Builds Up

Huge pressure develops in lithosphere
Especially in:
Igneous rocks
Fault zones

2. Activation of “p-holes”

Stress activates charge carriers
Called:
Positive holes (p-holes)

3. Movement Through Faults

Charges move rapidly upward
Fault systems act as conduits

4. Ionization of Atmosphere

Charges reach Earth’s surface
Contact with atmosphere ionizes air

5. Plasma-like Glow Forms

Creates luminous discharge
Appears as glowing lights in sky

6. Lithosphere–Atmosphere Coupling

Electric potential couples with:
Lower atmosphere
Ionosphere
Produces visible EQL phenomenon
Characteristics of EQL
Different Forms
Luminous spheres (ball lightning)
Vertical beams
Sheet lightning
Streamers
Localized glowing patches
Location Specific
~97% cases occur near:
Rift zones
Sub-vertical fault systems
Common where tectonic plates separate
Timing
Seen:
Before main earthquake
During crustal movement
Around seismic shocks
Silent Phenomenon
Unlike thunderstorm lightning:
Usually silent
No thunder sound
Significance
Possible Early Warning Signal
May indicate impending earthquake activity
Scientific Importance
Helps study:
Lithosphere–atmosphere coupling
Electrical properties of Earth’s crust
Seismic processes
Keywords for UPSC
Earthquake Lights (EQL)
p-holes

Governor’s Role in a Hung Assembly
What is a Hung Assembly?
• A Hung Assembly arises when no single party or pre-poll alliance gets an absolute majority in the State Legislative Assembly.
• In such a situation, the Governor plays a crucial constitutional role in government formation.
Constitutional Basis
Article 164(1)
• Governor appoints the Chief Minister.
• Normally acts on the aid and advice of the Council of Ministers.
• But in a hung Assembly, the Governor uses discretionary powers to decide whom to invite first.
Main Objective of Governor
• Ensure formation of a stable government.
• Identify the leader most likely to command majority support in the Assembly.
• Maintain constitutional continuity and avoid administrative vacuum.
• Role should remain constitutional, not political.
Order of Preference (Sarkaria + Punchhi Commission)
1. Pre-poll Alliance
• Coalition formed before elections.
• Gets first preference if it has majority support.
2. Single Largest Party
• Largest party may be invited if it can prove majority support with allies/independents.
3. Post-poll Coalition
• Parties joining together after elections and participating in government.
4. Outside Support Arrangement
• Government formed with support from outside parties or independents.
Key Constitutional Procedures
Floor Test
• Majority must be tested on the floor of the House.
• Governor cannot decide majority subjectively.
• Supreme Court has repeatedly emphasized floor test as the best method.
Time Limit
• Newly appointed CM generally asked to prove majority within a reasonable time (usually within 30 days).
Importance of Governor’s Role
• Prevents constitutional crisis.
• Ensures continuity of governance.
• Protects democratic legitimacy through floor test.
• Helps establish a government enjoying Assembly confidence.
Important Commissions
Sarkaria Commission (1983)
• Suggested order of preference for inviting parties to form government.
• Recommended neutrality of Governor.
Punchhi Commission (2007)
• Reaffirmed Sarkaria guidelines.
• Favoured quick floor tests to avoid political manipulation.
Important Supreme Court Judgments

The Rusty-spotted Cat (Prionailurus rubiginosus), one of the world’s smallest wild cats, has recently been photographed with a kitten in the Aravalli Range near Delhi-NCR, providing the first confirmed evidence of breeding in the region. Researchers from Indira Gandhi University documented the mother and offspring in Kot village, Faridabad, during field surveys conducted in 2025. The finding confirms that a resident breeding population exists in the Aravalli landscape despite increasing urbanisation and habitat disturbance.
The rusty-spotted cat is native to India, Nepal and Sri Lanka. It is known for its tiny size, reddish-grey fur and rusty coloured spots. The species is highly elusive, nocturnal and generally found in dry deciduous forests, scrublands and rocky habitats. Due to its secretive behaviour and low population density, sightings are extremely rare.
According to the International Union for Conservation of Nature (IUCN), the species is classified as “Near Threatened”, while in India it receives the highest legal protection under Schedule I of the Wildlife (Protection) Act, 1972. Nearly 75% of its habitat is believed to be threatened due to urban expansion, agriculture, quarrying and land-use changes.
The discovery is ecologically significant because it demonstrates that even fragmented green spaces around highly urbanised regions can support rare and sensitive wildlife. Researchers observed the cat surviving close to human settlements, challenging the earlier assumption that it avoids human presence entirely. The study also underlines the importance of the Aravallis, which act as an ecological barrier against desertification and provide critical biodiversity support for the NCR region.
The findings highlight the need for conservation strategies extending beyond protected forests to include non-protected landscapes, urban green spaces and wildlife corridors. They also strengthen the argument for sustainable urban planning and long-term conservation of the Aravalli ecosystem.

Hantavirus
A rodent-borne viral infection transmitted to humans.
Caused by viruses belonging to the Hantavirus group.
Known for causing severe respiratory or renal diseases with high fatality rates.
Transmission
Spread through inhalation of aerosolized particles from:
Rodent droppings
Urine
Saliva
Infection occurs when contaminated dust becomes airborne and is inhaled.
Human-to-human transmission is rare (important point)
Types of Diseases Caused
1. Hantavirus Pulmonary Syndrome (HPS)
Affects lungs
Symptoms:
Fever, fatigue → later cough & breathlessness
Fluid accumulation in lungs
Fatality rate ~40%
More common in Americas
2. Haemorrhagic Fever with Renal Syndrome (HFRS)
Affects kidneys
Symptoms:
Low blood pressure
Internal bleeding
Acute kidney failure
More common in Europe & Asia
Symptoms (Progression Pattern)
Early stage (1–8 weeks after exposure):
Fever
Fatigue
Muscle aches
Late stage (after 4–10 days):
Coughing
Shortness of breath
Fluid in lungs (in HPS)
Key point: Starts like flu but rapidly worsens
Treatment
No specific antiviral treatment
No widely available vaccine
Supportive care only:
Oxygen therapy
Fluid management
Intensive care support
Prevention
Avoid exposure to rodent-infested areas
Use:
Masks
Gloves while cleaning
Proper sanitation & rodent control
Recent News (Value Addition)
Suspected outbreak on a Netherlands-based cruise ship
Cases included deaths and infections, highlighting outbreak potential in closed environments
Exam-Traps / Key Takeaways
Rodent-borne virus (not mosquito-borne)
Airborne via droppings, not direct bite necessarily
Causes two syndromes: HPS & HFRS
High fatality + no specific cure
Often confused with:
COVID-19 (human-to-human spread dominant)
Dengue (vector-borne

Anti-Defection Law
Background
Introduced through 52nd Constitutional Amendment Act
Added Tenth Schedule to the Constitution
Objective:
➝ Curb political defections
➝ Ensure stability of governments
➝ Prevent horse-trading
Key Provisions
Applies to MPs and MLAs
Grounds for disqualification:
Voluntarily giving up party membership
Voting/abstaining against party whip
Decision authority:
Speaker (Lok Sabha/Assembly)
Chairman (Rajya Sabha)
91st Constitutional Amendment (2003)
Strengthened the law:
Two-thirds rule for merger (earlier 1/3 split allowed)
Removed split provision
Cap on ministers:
Max: 15% of House strength
Min: 12 ministers
Merger Rule
Valid defection only if ≥ 2/3 members join another party
Otherwise → Disqualification
Current Issue: Rajya Sabha Defection
7 MPs from Aam Aadmi Party joined Bharatiya Janata Party
Debate:
View 1: Valid merger (2/3 condition satisfied in RS)
View 2: Merger must apply to entire party, not just MPs
Key figure: Arvind Kejriwal (party leadership role in merger question)
🏛️ Role of Chairman (Rajya Sabha)
Can:
Accept merger → No disqualification
Reject → Start disqualification process
Decision subject to judicial review
Issues / Criticism
1. Loss of Legislative Independence
MPs/MLAs cannot vote freely
Fear of disqualification → “rubber stamp” role
2. Centralisation of Power
Power shifts to party leadership
Weakens representative democracy
3. Delay in Decisions
No time limit for Speaker/Chairman
Members continue despite pending cases
4. Legal Grey Areas
Ambiguity in:
Meaning of “voluntarily giving up”
Scope of merger (party vs legislature wing)
Impact on Parliament
Defecting MPs may:
Still be officially in old party
Vote for new alliance
Creates constitutional anomaly
Judicial View
Supreme Court of India:
Allows judicial review after decision
Advises timely disposal (no fixed limit)
Important Points for Mains Answer
Balance needed between:
Political stability vs legislative freedom
Suggested reforms:
Independent tribunal (instead of Speaker)
Time-bound decisions
Limit whip only
