Volcanoes And Associated Geophysical And Geographical Features

Volcanic eruptions are powerful and hazardous events, often associated with spectacular volcanic lightning. Recent examples include the Taal Volcano (October 2025), which had phreatic and phreatomagmatic eruptions producing plumes up to 2,100 meters high and volcanic lightning. Similarly, the major eruption of Mount Ruang, Indonesia (April 2024), led to mass evacuations and gained widespread attention for the dramatic lightning observed within its ash cloud.

ABOUT VOLCANOES

Volcanic landforms are the result of endogenic (internal Earth) processes and are most commonly found along tectonic plate boundaries or above mantle plumes (hotspots).

Definition: A volcano is a geographical feature defined as an opening, vent, or fissure in the planet’s crust—from which molten rock (called magma when beneath the surface and lava when expelled), volcanic ash, gases, and other pyroclastic materials erupt onto the surface.

Key features and components of a volcano:

Magma chamber: it contains the reservoir of molten rock beneath the surface.
Conduit: passageway for the ascent of the molten magma.
Vent/ Fissure: It is the surface opening on the crust leading to eruption.
Volcanic edifice: The physical structure resulting from accumulated eruptive materials.

Types of volcanic eruption:

Volcanoes can be active, dormant, or extinct, depending on their current and historical eruptive activity

Socio – Economic Impacts

The economic loss due to mental health conditions, between 2012-2030, is estimated at USD 1.03 trillion.
Annual employer loss: ₹1.1 lakh crore (due to absenteeism, attrition, burnout).
Escalate general healthcare expenditures for families and the system.
traps families in poverty, and limits social mobility.
Social exclusion: discrimination, isolation, and loss of social support.
Undermine academic performance, raise dropout rates, and reduce human capital formation.
Strain on the criminal justice system: Higher rates of violence, substance abuse, and conflict challenge societal order and law enforcement.
Reduced life expectancy: People with serious mental disorders die 10–20 years earlier from chronic physical illnesses and suicide.
Hindrance to Sustainable Development Goals (SDGs): Poor mental health undermines progress on SDG 1: No Poverty; SDG 3: Good Health and Well-being; SDG 4: Quality Education & SDG 5: Gender Equality.

Mental Healthcare Challenges

Psychiatrists: 0.75 per 1,00,000 (WHO minimum: 1.7, ideal: 3)
Shortage: Psychiatrists, psychologists, social workers
Over 80% of districts lack even one government mental health professional.
Chronic Underfunding: Mental health receives 1.05% of the total health budget, with most states spending far less.
National mental health programme (NMHP) and District Mental Health Programme (DMHP) cover less than 50% of Indian districts.
Very few community-based rehab centers, especially outside major cities; most care is hospital-centric and short-term.

GoI: Policy and Action

National Suicide Prevention Strategy (2022): Aim to reduce deaths by 10%
- Outcome so far: Suicides have increased.
- Focuses on vulnerable populations, awareness, and crisis hotlines.
Mental Healthcare Act (2017):
- Decriminalised suicide
- Guaranteed right to mental health care
- Mandated insurance coverage for mental illness treatment.
National Mental Health Programme (NMHP) (since 1982)
- Integrates mental health with general healthcare.
- Focus on early detection, community-based interventions, and destigmatization.
District Mental Health Programme (DMHP)
- Expands mental health services to district levels.
- Covers more than 50% of districts but faces implementation gaps.
Tele-Mental Health Assistance and Networking Across States (Tele-MANAS) (2022)
Manodarpan scheme: School-based psycho-social support remains largely inactive
₹270 crore mental health budget: Mostly unspent
Mental health receives only 1.05% of India’s health budget, compared to 8–10% in Australia, Canada, UK.

CASE STUDIES AND GLOBAL BEST PRACTICES:

United Kingdom — Collaborative Care Model
- Mental health nurses co-located with general practitioners (GPs) in primary care.
- Stepped care and patient-centered approaches
Australia — Mental Health Nurse Incentive Program: integration of mental health into everyday program.
Uganda & South Africa — Multi-sectoral Community Forums: community led forums in different sectors driving rehabilitation.
WHO’s Mental Health Gap Action Programme (mhGAP)
- Training non specialists and creating a pool of mental health interventionists in countries like india.
Kerala as a role model state for addressing mental health crisis through effective district mental health programmes
- Adopted community mental health model
- Early detection counselling to achieve stepped treatment.
- Peer led education and awareness
- Wide district coverage and outpatient services.
- Mental health care is free at the point of delivery, promoting universal access regardless of income.
- leveraging non-specialist community/health workers, through training and supervision.
Probable solutions and way forward.
- India must prioritize mental health, treating it as an emergency. This requires cross-ministerial task forces (health, education, agriculture, women/child welfare) and aiming for 3-5 mental health professionals per 100,000 people within five years. Counselling should be public infrastructure, with trained counsellors in every school, college, district hospital, and agrarian block. Public campaigns are needed to destigmatize help-seeking, share recovery stories, and normalize conversations about distress. For farmers, counselling must be combined with debt relief and livelihood support. In coaching hubs like Kota, mental healthcare needs to be continuous, institutional, and preventive. Emotional-support apps and AI tools must disclose privacy risks, have disclaimers, embed crisis-response redirections, and offer real-time access to licensed professionals.

Mental Health Concepts and Descriptions

Mental Health Concepts

Concept	Description / Explanation
DALY (Disability Adjusted Life Year)	Combined measure of years lost to illness, disability, or early death; quantifies overall disease burden.
Alzheimer’s Disease	Progressive, irreversible brain disorder causing memory loss, confusion, and cognitive decline.
Dementia	Group of conditions marked by decline in memory, reasoning, and thinking, impairing daily functioning.
Burnout Syndrome	Prolonged work-related stress leading to emotional exhaustion, detachment, and reduced professional efficacy.
Stepped Care	Treatment model where care intensity is matched to severity; escalates support only as needed.
