EARTHQUAKE ALERT! SMART APPS FOR OUR SAFETY

A high-intensity earthquake measuring 7.9 on the Richter scale rocked Nepal along with many parts of east and north India, including Delhi on Saturday. The tremors, which were felt in Bihar, West Bengal, Uttar Pradesh, Rajasthan, Haryana and Punjab, lasted for about a minute and have taken away over 3000 lives.

The the past few years have seen many natural disasters striking highly populated regions around the world. Social media played a major role as well, as news spread over Twitter and Facebook. Technology over the years has improved and there’s particularly high level of interest when it comes to earthquakes and tsunami warning systems. Sensors and control centres have been setup all around the world that monitor seismic activity around the world. They communicate each other and fortunately, all this information is made public.

A whole bunch of developers have designed apps that read information from these centres and let you get alerts of earthquakes and tsunamis as they happen. We’ve compiled best free apps for iOS, Android and Blackberry. They can be handy to inform your dear ones or possibly even predict an upcoming earthquake or tsunami.

The most popular seismic activity monitoring app on the Android Play store is called Earthquake Alert!

Earthquake Alert! has an ad banner that’s visible at the bottom on one of the three tabs in this app – the news feed. The first tab displays all recent earthquakes and tremors while the second shows the map with all the points of activity on the map. Powerful earthquakes and tremors are marked in red while smaller ones are marked in green. Users can choose to filter quakes by their intensity, distance from you or by time. The app even lets you quickly send the news to others over a few messaging apps. If you felt the tremor, you can register your feedback on it by posting a comment on the USGS site.

2.Vibration Meter (ANDROID) (ONLINE ALERTS) 

BEST APP I PERSONALLY USE

Vibration Meter is in the 4th set of Smart Tools collection (seismograph, seismometer, body tremor).

This app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seism detector.

The measured values are the Modified Mercalli Intensity scale(MMI), and just for reference. If it is inaccurate, you can calibrate it so that the maximum value is about 10-11.
