Can effects and after effects of natural disaster be tamed?
Several million earthquake hits
our ground every year and majority of them does not get detected due to small
magnitude or occurrence in a remote area. But the big earthquakes which are
larger in magnitudes impact our lives to a great extent in terms of life and
economic loss. Now the main question is how to reduce the losses to the minimum
level or how to avoid the major losses? How the emerging technology can help us
in minimizing damages and maximizing safety?
Around 13000 people loose their
lives per year due to earthquakes and approximately 5 million people gets
severely affected by it. Recently the
stability of Indian subcontinent was disturbed multiple times by a major earthquake
and it’s after effect whose epicenter was located deep in Himalayas in Nepal
and was measured 7.9 on Richter scale. It was estimated that about as many as
10000 people were dead and around 25 percent to Nepal’s GDP was destroyed. This
is a huge loss for a developing nation which has pushed it many year back. Can
technology help in reducing these damages?
Scientists are unlikely to be
ever able to predict earthquakes with any amount of certainty, according to the
United States Geological Survey (USGS). They can say that an earthquake
can hit a particular place in near future but cannot predict exactly when it
can occur. However, big data analytics is providing the leap in accuracy of
quake predictions, says Forbes, with recent predictions being 90% accurate.
Companies using satellite data are increasingly able to forecast
major quakes from one to 30 days before they occur in all key seismic prone
areas.
In today’s time we are well
connected and by using SMS massaging, GPS signalling, stable wifi and
constantly in use social media can made a cluster which can be helpful in relief
work and even pre calamity data can be helpful in finding out trends and more
accurately predicting natural disasters. Even the Crisis mapping technology and
evolving of digital maps are extremely useful sources to expand relief programs
in the disaster affected regions. Currently USA and Japan are working jointly
in developing six different projects on disaster management using Big Data and
data analytics.
Google has launched People Finder
after Haiti earthquake in 2010 and it was updated around 5300 times in first
two days of Nepal Earthquake. Facebook’s safety check also covers people whose
GPS data shows that they are in danger zone. Similarly during Sandy storm, Geeks
without bounds and Splunk4Good worked together to analyse data from Twitter
feeds so as to find out patterns and trends of activities in certain area. The
European Commission, together with the Inter-Agency Standing Committee has
developed an Index for Risk Management (INFORM), an open-source global risk
analysis tool for understanding the risk of humanitarian crises and disasters.
Using data from 191 countries, INFORM can assess a country or region’s actual
risk with high levels of specificity.
It has also been proposed by
scientists to study electromagnetic fields which are thought to be changed just
before earthquakes. Animals can sense earthquake more effectively and much
before then human beings. According to a study published in journal of Zoology
that 96% of male toads abandoned their breeding site five days before the
earthquake which struck almost 74 KM away. May be in near future we may borrow
this disaster detecting ability from animals and we may become more equipped in
reducing damages from natural disasters.
Amazing write up. I look forward to such efficient technologies !!!
