Seismicity and Earthquakes in Indian subcontinent

Seismicity and earthquakes are significant geological phenomena in the Indian subcontinent. Here's an explanation of these concepts in the context of the region:

1. Seismicity in the Indian Subcontinent:

- Seismicity refers to the occurrence and distribution of earthquakes in a specific area. The Indian subcontinent is one of the most seismically active regions in the world.

- This heightened seismic activity is primarily due to the tectonic plate boundaries and interactions within the region. The Indian Plate is converging with the Eurasian Plate, leading to intense tectonic stress and the release of energy in the form of earthquakes.

2. Earthquakes in the Indian Subcontinent:

- Earthquakes are the sudden shaking or trembling of the Earth's surface caused by the release of energy along geological faults or plate boundaries.

- In the Indian subcontinent, the most prominent and well-known earthquake-prone region is the Himalayan region. This area experiences frequent seismic events as the Indian Plate continues to collide with the Eurasian Plate.

- The Himalayan earthquakes are often associated with the Main Himalayan Thrust (MHT) fault, where the two tectonic plates are locked together and periodically release stress, resulting in large earthquakes.

Notable Earthquakes in the Indian Subcontinent:

- One of the most devastating earthquakes in recent history was the 2015 Nepal earthquake. It had a magnitude of 7.8 and caused widespread destruction in Nepal and parts of India.

- The 2001 Gujarat earthquake, with a magnitude of 7.7, struck the western part of India, causing significant damage and loss of life.

- Historical records also document major earthquakes in the past, like the 1905 Kangra earthquake in northern India.

In summary, seismicity in the Indian subcontinent is a consequence of the ongoing collision between the Indian Plate and the Eurasian Plate, resulting in frequent earthquakes, particularly in the Himalayan region. These seismic events have had significant social, economic, and geological impacts on the region throughout history.

RADIOMETRIC CORRECTION

Radiometric correction is the process of removing sensor and environmental errors from satellite images so that the measured brightness values (Digital Numbers or DNs) truly represent the Earth's surface reflectance or radiance. In other words, it corrects for sensor defects, illumination differences, and atmospheric effects. 1. Detector Response Calibration Satellite sensors use multiple detectors to scan the Earth's surface. Sometimes, each detector responds slightly differently, causing distortions in the image. Calibration adjusts all detectors to respond uniformly. This includes: (a) De-Striping Problem: Sometimes images show light and dark vertical or horizontal stripes (banding). Caused by one or more detectors drifting away from their normal calibration — they record higher or lower values than others. Common in early Landsat MSS data. Effect: Every few lines (e.g., every 6th line) appear consistently brighter or darker. Soluti...

Geometric Correction

When satellite or aerial images are captured, they often contain distortions (errors in shape, scale, or position) caused by many factors — like Earth's curvature, satellite motion, terrain height (relief), or the Earth's rotation . These distortions make the image not properly aligned with real-world coordinates (latitude and longitude). 👉 Geometric correction is the process of removing these distortions so that every pixel in the image correctly represents its location on the Earth's surface. After geometric correction, the image becomes geographically referenced and can be used with maps and GIS data. Types 1. Systematic Correction Systematic errors are predictable and can be modeled mathematically. They occur due to the geometry and movement of the satellite sensor or the Earth. Common systematic distortions: Scan skew – due to the motion of the sensor as it scans the Earth. Mirror velocity variation – scanning mirror moves at a va...

Atmospheric Correction

It is the process of removing the influence of the atmosphere from remotely sensed images so that the data accurately represent the true reflectance of Earth's surface . When a satellite sensor captures an image, the radiation reaching the sensor is affected by gases, water vapor, aerosols, and dust in the atmosphere. These factors scatter and absorb light, changing the brightness and color of the features seen in the image. Although these atmospheric effects are part of the recorded signal, they can distort surface reflectance values , especially when images are compared across different dates or sensors . Therefore, corrections are necessary to make data consistent and physically meaningful. 🔹 Why Do We Need Atmospheric Correction? To retrieve true surface reflectance – It separates the surface signal from atmospheric influence. To ensure comparability – Enables comparing images from different times, seasons, or sensors. To improve visual quality – Remo...

Supervised Classification

In the context of Remote Sensing (RS) and Digital Image Processing (DIP) , supervised classification is the process where an analyst defines "training sites" (Areas of Interest or ROIs) representing known land cover classes (e.g., Water, Forest, Urban). The computer then uses these training samples to teach an algorithm how to classify the rest of the image pixels. The algorithms used to classify these pixels are generally divided into two broad categories: Parametric and Nonparametric decision rules. Parametric Decision Rules These algorithms assume that the pixel values in the training data follow a specific statistical distribution—almost always the Gaussian (Normal) distribution (the "Bell Curve"). Key Concept: They model the data using statistical parameters: the Mean vector ( $\mu$ ) and the Covariance matrix ( $\Sigma$ ) . Analogy: Imagine trying to fit a smooth hill over your data points. If a new point lands high up on the hill, it belongs to that cl...

Supervised Classification

Image Classification in Remote Sensing Image classification in remote sensing involves categorizing pixels in an image into thematic classes to produce a map. This process is essential for land use and land cover mapping, environmental studies, and resource management. The two primary methods for classification are Supervised and Unsupervised Classification . Here's a breakdown of these methods and the key stages of image classification. 1. Types of Classification Supervised Classification In supervised classification, the analyst manually defines classes of interest (known as information classes ), such as "water," "urban," or "vegetation," and identifies training areas —sections of the image that are representative of these classes. Using these training areas, the algorithm learns the spectral characteristics of each class and applies them to classify the entire image. When to Use Supervised Classification: - You have prior knowledge about the c...
