Government Tightens Online Content Blocking Rules, Adds Senior-Level Oversight

Context: The Ministry of Electronics and Information Technology (MeitY) has amended the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021 to introduce new safeguards and senior-level oversight in online content blocking under Section 79(3)(b) of the IT Act, 2000.

Key Highlights of the Amendment

Who Can Now Issue Blocking Notices

Only senior officials are now authorised to issue content removal or flagging notices to platforms such as YouTube, X (formerly Twitter), and Instagram.
Authorised officers include:

Joint Secretary (JS) or equivalent officer at the Centre/State.
Director-level officers, where no JS exists.
DIG or above, in police departments, specifically authorised.

Each order must clearly specify:

Legal basis and statutory provision
Nature of the unlawful act
Exact URL/digital location of content

A monthly review of all such orders will be conducted by an officer not below the rank of Secretary (e.g., IT Secretary or State Home Secretary).

Rule 3(1)(d): The Legal Basis

Under Rule 3(1)(d) of the IT Rules, 2021, the government can flag content that violates Indian law.

If platforms fail to act, they may lose “safe harbour” protection—their legal immunity from user-generated content liability.
Such notices act as warnings, not direct takedown orders.

Why the Change Was Needed

In some states, junior police officers (like Sub-Inspectors or ASIs) had been issuing blocking notices, raising concerns of misuse and lack of accountability.
The amendment ensures that only senior officers can exercise this power, promoting transparency, due process, and uniformity across states.

Background: X vs. Government Case

Elon Musk’s X (formerly Twitter) had legally challenged the government’s use of Rule 3(1)(d), calling it arbitrary and unconstitutional.
The Karnataka High Court, however, upheld the government’s authority.
Officials clarified that the new amendment is not a reaction to X’s case but does address its core concern by defining clear authority and procedure.

Section 79(3)(b) vs Section 69A

Provision	Purpose	Key Feature
Section 79(3)(b)	Removal of unlawful content	Platforms lose “safe harbour” if they fail to act
Section 69A	Blocking content on grounds of national security, integrity, or defence	Direct blocking by government agencies

Significance

The amendments mark a shift toward responsible digital governance, ensuring that content blocking powers are exercised with legal clarity, senior oversight, and procedural accountability.

They balance freedom of expression with the need to curb misuse and maintain lawful online spaces.

Taftan Volcano Reawakens After 700,000 Years

Context: According to reports from Live Science (LS), the Taftan Volcano in southeastern Iran appears to have shown renewed activity after nearly 700,000 years of dormancy. Scientists have detected increased geothermal emissions and seismic tremors in the region, suggesting reactivation within the long-dormant volcanic system.

About Taftan Volcano:

Location: Situated in Sistan–Baluchestan Province of southeastern Iran, near the Pakistan border, Taftan is the highest volcano in Iran and one of the few active ones in the Makran volcanic arc.
Elevation: Approximately 3,940 meters (12,927 feet) above sea level.
Volcano Type: Stratovolcano (Composite Cone) — built up by successive eruptions of lava flows, ash, and pyroclastic material.
Tectonic Setting: Lies within the Alborz–Makran volcanic belt, where the Arabian Plate is being subducted beneath the Eurasian Plate.
This subduction process generates magma that feeds volcanoes like Taftan.
Geological Features:
- Active hydrothermal vents and fumaroles continuously emit sulphur gases.
- Presence of sulphur deposits, hot springs, and altered rocks around the summit indicates ongoing geothermal activity.
- The last confirmed eruption occurred around 710,000 years ago, during the Pleistocene epoch.

Understanding Stratovolcanoes (Composite Cones):

Structure: Tall, steep-sided cones composed of alternating layers of lava, ash, and tephra.
Magma Composition: Typically andesitic, sometimes basaltic to rhyolitic — rich in silica, causing viscous magma and explosive eruptions.
Eruption Style: Highly explosive, often producing pyroclastic flows and ash clouds that can travel large distances.
Tectonic Environment: Common in subduction zones — regions where an oceanic plate sinks beneath a continental plate.
Famous Examples:
- Mount Fuji (Japan)
- Mount Vesuvius (Italy)
- Volcán de Fuego (Guatemala)
- Mount St. Helens (USA)

Significance of Taftan’s Reactivation:

Geological Insight: Offers rare evidence of volcanic reawakening in the Makran arc, a region otherwise known for earthquakes and subduction-related hazards.
Regional Impact: Increased geothermal activity could pose risks to local settlements and infrastructure but also offers geothermal energy potential.
Scientific Relevance: Helps in studying the Arabian–Eurasian plate interaction, crucial for understanding seismic and volcanic hazards across Iran, Pakistan, and Afghanistan.

Conclusion:

The potential reawakening of Taftan Volcano underscores the dynamic nature of the Earth’s lithosphere. While dormant for nearly a million years, its renewed activity reminds us that even ancient volcanic systems remain geologically alive — warranting close monitoring and regional preparedness.
