Earthquake

A Stitch in Time

By: Manu Gupta

Making Disaster Risk Reduction a Priority for Everyone. Long term mitigation planning, and ensuring that all new development is sensitive to potential risks is the need of the hour, given the fact that South Asia is vulnerable to major earthquakes in the future.

Developing a Disaster Management Strategy

By: C P Rajendran

The recent Nepal earthquakes should be viewed as an opportunity to rethink earlier attitudes, and have us embark on a disaster management strategy based on mitigation, rather than mere response.

The Nepal Earthquake: The Mechanics of Devastation

By: G P Ganapathy

The Eurasian and Indian plates meet along the central part of Nepal. The subducting Indian plate thrusting into the Eurasian plate makes Nepal a highrisk seismic zone. In such a scenario, measures to minimise quake-related damage is imperative.

Tremors in Bihar

By: Anil K Sinha and Asif Shahab

Awareness on how to deal with disasters can significantly prevent trauma-related issues, as also deaths and injuries caused by earthquakes in seismically active regions.

Traditional Genius and Earthquakes

By: Piyoosh Rautela

Traditional building techniques have always existed in regions vulnerable to earthquakes. Unfortunately, aspirations to modernity have tended to bury these norms, resulting in heavy casualties in recent times.

Building on a Flood Plain and a Fault Zone

By: Staff Reporter

A nation that seeks to educate the common man about the pitfalls of poor siting on one hand, chooses to do an exact opposite on the other.

Career in Disaster Management

By: Anup Kumar

India is a country prone to natural and anthropogenic disasters. There is thus an earnest need for persons trained in disaster management.

Bangladesh’s Sundarban: Calling for a Spill Proof Environment

By: Staff Reporter

The alarming rate of wrecks in the Sundarban raises a larger question. Why is there no alternative safer route envisaged in a time bound manner by Bangladesh?

Pethia Striata: Western Ghat’s Newly Discovered Member

By: Staff Reporter

The new species will be an addition to Cyprinidae, the largest family of fish that encompasses other common fishes like the gold fish and the common carp.

Last of the True Bovines

By: Staff Reporter

The resemblance to their domestic seers has placed them at the fag end of everyone’s interest and this perpetual neglect, has in turn, pushed the entire species to the edge of extinction.

Towards Risk Sensitive Development

The Land Acquisition Legislation: An Update

By: Staff Reporter

The present government has placed a huge stake on the Land Acquisition Amendment Bill. It is convinced that without it all the proposed schemes in the social sector and reforms in the industry will not take place. It also treats two classes—consent and social impact assessment, as major hurdles in achieving its objectives. Only time will tell whether the government has got the correct assessment of the ground situation.

High Risk-High Gain Changing Facets of Indian Research

Asutosh Sharma, Secretary, Department of Science and Technology, in a fresh new take, shares his views about risk taking in science with the editor G’nY.

In brief

Term Power

What is ...

It is a smaller earthquake tremor that occurs after a large earthquake, in the same area of the main shock. It results from the sudden change in stress occurring within and between rocks and the previous release of stress brought on by the principal earthquake. Aftershocks occur in rocks located near the epicentre or along the fault that harboured the principal earthquake.

They are instruments used to detect and record earthquakes. It is used for measuring the direction, intensity, and duration of earthquakes by measuring the actual movement of the ground.

It is the practice of exploiting a natural disaster, a miserable condition or emergency situation for one's selfish advantage. This term was used to describe the US Government’s reaction over Hurricane Katrina.

It refers to a movement of individuals or groups who are actively preparing for emergencies including possible disruptions in social or political order, on scales from local to international. These individuals/groups are called survivalists or preppers.

The Richter magnitude scale is used to measure the amount of energy released by an earthquake. Also known as Richter scale, it is used by seismologist to express seismic energy. Nowadays, moment magnitude scale is preferred because it works over a wider range of earthquake sizes and is applicable globally.

Stress accumulation that may occur between two locked plates can result in potentially destructive types of earthquake. It occurs at subduction zones at destructive plate boundaries, where one tectonic plate is subducted by another. Since 1900, all earthquakes of magnitude 9.0 or greater have been mega thrust earthquakes.

It is an event where a local area experiences sequences of many earthquakes striking in a relatively shorter period of time. Earthquake swarms are typically witnessed before volcanic eruptions.

Soil Liquefaction refers to the phenomenon whereby soil loses strength and stiffness in response to an applied stress, usually earthquake, shaking or other sudden change in stress conditions. This prompts the soil to behave like liquid. The strength of the soil decreases and, the ability of a soil deposit to support foundations for buildings and bridges is reduced.
