About the African Union (AU):

Establishment: Formed in 2002, replacing the Organisation of African Unity (1963).
Membership: 55 African countries.
Headquarters: Addis Ababa, Ethiopia.
Vision: “An Integrated, Prosperous, and Peaceful Africa, driven by its own citizens.”
Agenda 2063: Blueprint for socio-economic growth and continental unity.
Main Organs: Assembly, Executive Council, AU Commission, Peace and Security Council.

What is a Mercator Map?

Creation: Designed in 1569 by Gerardus Mercator.
Projection: Cylindrical map with straight longitude and latitude lines intersecting at 90°.
Purpose: Enabled sailors to plot straight-line courses for compass navigation.
Adoption: Became the standard map in schools, atlases, and wall charts by the 19th century.

Issues with the Mercator Map:

Distortion: Enlarges high-latitude regions (Europe, Russia, North America) while shrinking Africa and South America.
Example: Greenland appears equal to Africa, though Africa is ~14 times larger.
Colonial Bias: Reinforced Western dominance narratives and downplayed Africa’s size and importance.
Impact: Supported marginalisation and exploitation during colonialism.
Alternatives: Gall-Peters (1970s) and Equal Earth (2018) projections show continents in correct proportion.
AU Stand: Advocates replacing Mercator maps to restore Africa’s rightful global image.

Tsunami Waves triggered by quakes in Kamchatka Peninsula

31 July 2025 | Prelims Only World Mapping | Geography

Mains Paper 1: Geographical Features & Their Location

Why in the News?

An 8.8 magnitude earthquake hit off Russia’s Kamchatka Peninsula, triggering 16-foot tsunamis that reached Hawaii and northern California in the US.

About Earthquakes:

Overview: Sudden ground shaking caused by release of stored energy in Earth’s crust due to tectonic stress.
Cause: Occurs when tectonic plates slip at fault lines where stress had built up due to friction.
Seismic Waves: Energy travels as:
- Primary Waves (P-waves): Fastest, compressional.
- Secondary Waves (S-waves): Slower, shear motion.
Key Terms:
- Focus (Hypocenter): Underground origin point.
- Epicenter: Surface point directly above the focus.
Measurement:
- Magnitude: Energy released (Richter Scale, logarithmic).
- Intensity: Observed ground shaking (varies by location).
- Seismograph: Records seismic wave activity.

How Earthquakes Trigger Tsunamis?

Underwater Epicenter: Must occur beneath oceans to displace water.
Shallow Depth: Quakes at <70 km transfer energy more efficiently to water surface.
Reverse Faulting: One tectonic plate pushes over another, vertically shifting the seafloor.
Rapid Displacement: Sudden seafloor uplift/downthrust generates massive water waves.
High Magnitude: Quakes >7.0 (especially >8.0) likely to trigger tsunamis.

About the Kamchatka Region:

Overview: Russian Far East; borders the North Pacific Ocean.
Tectonic Zone: Sits on the Kuril-Kamchatka Trench—Pacific Plate subducting under Okhotsk Plate at ~86 mm/year.
Seismic Hotspot: Historical major quakes in 1841, 1923, 1952, 2006, and 2020.
Ring of Fire: Part of the 40,000 km Pacific Ring of Fire , known for quakes and volcanoes.
2025 Earthquake:
- Depth:3 km (shallow)
- Impact: Triggered tsunami waves up to 16 ft—one of the strongest earthquakes since 1900.

[UPSC 2004] Consider the following geological phenomena:
