Dated : 12th May 2015......::A huge earthquake measuring 7.4 on the Richter scale hit Nepal today at about 12.35 pm, US Geological Survey said; tremors were felt across major swathes of North India, including Delhi, at about 12.40 pm today. News agency Associated Press reports that today's quake was epicentred between Mount Everest and the Nepali capital of Kathmandu, which was devastated on April 25 by a temblor that weighed in at 7.9. 8,000 people had been killed and more than 17,000 injured in Nepal in the earthquake. 50 people had died in Biha

People rushed out of their homes and offices in cities like Patna in Bihar and Gurgaon near Delhi. "News of an earthquake hitting Nepal again has come. Several parts of India also felt the tremors. MHA is collecting more details and info," tweeted Home Minister Rajnath Singh.

Like April's earthquake, today's was shallow - 10 km deep. Shallow quakes are more deadly because the amount of energy released is focused over a smaller area.

People in Kathmandu rushed outdoors, Reuters reporters said. There were no immediate reports of damage to buildings. Shopkeepers closed their shops.

Reuters also reported that the quake's epicentre was close to Everest Base Camp, which was evacuated after an avalanche triggered by the April 25 quake killed 18 climbers. Mountaineers seeking to scale the world's tallest peak have called off this year's Everest season.

It is suggested from us that people should vacate from hilly and mountainous regions as soon as possible.
Hilly areas are no longer safe for habitation.

Stay safe.







25th April 2015

Dated : 25th April 2015......:: ‘The earthquake in Nepal is a continuing nightmare for many. As the death toll mounts in the region, anxiety increases for those still in search of their loved ones. So why do earthquakes occur? This video tells you that they are indeed a daily occurrence all over the globe. Watch it to understand why we feel some earthquakes, and why we don't feel others..’

High intensity earthquakes are a very real threat in the Indian subcontinent. However, there are clear zones marked, differentiating the extent of threat. These zones are known as 'seismic zones'.

"The Geological Survey of India (GSI) first published the seismic zoning map of the country in the year 1935. With numerous modifications made afterwards, this map was initially based on the amount of damage suffered by the different regions of India because of earthquakes," Hindustan Times notes.

Ranging from off-white, pink, red to a dark brown, there are four zones marked out on the map of India, that differentiate the extent of threat from earthquakes within the country. Are you at risk? Find out.

Zone - II: Least amount of threat

Zone - III: Moderate threat

Zone - IV: High threat

Zone - V: Extreme threat of earthquake

The earthquake that occurred on Saturday, April 25, measured 7.9 magnitude. The biggest aftershock that followed on Sunday, April 26 measured 6.7 magnitude. If you wondered how intense the latter was, here's how the calculation of magnitude works.

"Based on their magnitude, quakes are assigned to a class. An increase in one number, say from 5.5 to 6.5, means that a quake's magnitude is 10 times as great," the HT report states.

The earthquake that has taken thousands of lives in Nepal, fell under the 'major' bracket of earthquake magnitudes.

A 'great' magnitude is greater than or equal to 8.0, 'major' ranges from 7.0 to 7.9, 'strong' is between 6.0 and 6.9, 'moderate' is 5.0-5.9, 'light' is 4.0-4.9, 'minor' is 3.0-3.9, 'micro' measures 2.5-3.0. Even a 'moderate' earthquake can cause considerable damage.

What's troubling is that the aftershocks of this quake have ranged from moderate to strong.

As terrifying as it sounds, many more aftershocks are expected in and around the region, and this includes India.


Stay safe.
