Nepal Earthquake: Afterthoughts
NEPAL, AS OF NOW
Sitting at the base of Mount
Langtang, a 7000m high mountain
in the Nepalese Himalayas, there's
a small village of the same name.
On April 25, 2015 right when the
sun was high up in the Langtang
valley, the little village of 200
people was destroyed completely.
The avalanche that followed the
notorious Nepal earthquake had
completely wiped the little village
off the face of the earth.
Now, almost two weeks after the
incident, the death toll in Nepal has

e. the Richter scale values. We familiarise with a particular earthquake event by a number like 6 or 7 magnitudes. In
case of the Nepal earthquake, we all know it was a 7.8, right? The question remains, is this the right way to estimate the deadliness of earthquakes?
To understand this better, there are three critical parameters – magnitude, intensity and shaking. Shaking is quantified by the acceleration of the earthquake waves and
it's the primary determinant of the havoc and damage. Larger ground accelerations lead to more intense earthquakes – ultimately resulting in earthquakes of massive
But ultimately the thing that's most critical in determining the "badness" is the intensity of an earthquake at a particular location. An earthquake only has one single
magnitude, but it has different intensities based on location, distance from the source (epicentre) and duration of the shaking. There's a scale of intensity of earthquakes
ranging from IXII. Intensities over VII imply severe damages and property losses. The intensity of the Nepal earthquake was IX, categorised as "violent".
SUGGESTIONS FOR SURVIVAL
Though there are no active fault lines within Bangladesh territory, there are some surrounding its perimeter. And so, we should better prepare for a major event
occurring any day.
What to do in the event of an earthquake? We all know that it's utter pandemonium. People rattling and shouting down the staircase – sound familiar? Well, the most
verified course of action is to "Drop, Cover and Hold on." It has proven more effective when it comes down to saving lives than other techniques out there like the
"Triangle of Life." Drop on all fours immediately if there is vigorous shaking. Take cover under a sturdy desk/low lying furniture. If there aren't any, take cover
against an interior wall (NEVER exterior walls!). Hold on to your shelter or try covering your head and neck with hands.
