How Tsunami warning withdrawn after Massive earthquake struck Indonesia

All countries including India has finally withdrawn the tsunami warning that was reported earlier. It was reported around 28 countries issued tsunami warning earlier.  National Disaster Management Authority Vice President Sashidhar Reddy told that there is no specific threat. There is no likelihood of any tsunami in the Indian Ocean region.

Why there is no Tsunami in 2012 but in 2004?

Tsunami 2004

Reason: In case of 2004, tsunami is caused due to vertical displacement plates or large body movement. In 2012, There is no tsunami after Major Earthquake struck Indonesia because of horizontal displacement plates or large body movement.

How Tsunami is caused due to Earthquakes?

Tsunami Ocean Effect

Tsunami are caused by the abrupt vertical displacement of a large volume of a body of water, usually from natural sources of kinetic energy. These forces produce a wave that shifts not just a few meters of surface water, but the entire column of water from the floor to the surface.

Tsunami contain enormous amounts of energy. Earthquakes that cause tsunami often occur offshore at tectonic plate subduction zones.

As the sea floor snaps up in response to the tectonic plate movement and subsequent earthquake, the tsunami wave is formed and moves out from the source of the displacement.

The wave increases in height as it enters more shallow waters close to land.

Canada’s largest children’s rehabilitation hospital have developed a new technique that uses infrared light brain imaging to decode preference with the goal of ultimately opening the world of choice to children who can’t speak or move.

Bloorview scientists demonstrate the ability to decode a person’s preference for one of two drinks with 80 per cent accuracy by measuring the intensity of near infrared light absorbed in brain tissue.
This is the first system that decodes preference naturally from spontaneous thoughts,”
After teaching the computer to recognize the unique pattern of brain activity associated with preference for each subject, the researchers accurately predicted which drink the participants liked best 80 per cent of the time.

Most brain-computer interfaces designed to read thoughts require training.
Wearing a headband fitted with fibre-optics that emit light into the pre-frontal cortex of the brain, they were shown two drinks on a computer monitor, one after the other, and asked to make a mental decision about which they liked more. “When your brain is active, the oxygen in your blood increases and depending on the concentration, it absorbs more or less light.”

Luu says. “In some people, their brains are more active when they don’t like something, and in some people they’re more active when they do like something.”

Luu says. The brain is too complex to ever allow decoding of a person’s random thoughts. “However, if we limit the context limit the question and available answers, as we have with predicting preference – then mind-reading becomes possible.

What happen’s if you don’t have the SSL?

  • If the SSL certificate gets flagged as invalid by the browser, the data exchanged between you and the website you’re trying to connect to will be transferred in cleartext. Potentially, any user credentials or other sensitive data communicated over the channel can be sniffed or stolen. It is always recommended not to proceed over an insecure connection.
  • The user’s visiting your website will lose trust due to a lack of perceivable credibility.
  • Some users might be convinced that you are hosting a malicious website and would choose to steer clear even after the issue gets fixed.
  • Adversely impacts business and brings down the reputation especially if you are not a known player experiencing a temporary technical glitch.

The intention behind having an SSL/TLS certificate was not just for authentication but also to establish the identity of the remote server with whom the client browser communicates.

SSL /TLS protocol to ensure that data travels securely over the wire. Encrypting data in transit helps to prevent any malicious user from sniffing the network to steal sensitive information like passwords, credit card details, etc.

SSL or Secure Sockets Layer and TLS (Transport Layer Security) are cryptographic protocols designed to provide a secure communication channel between clients and servers over the internet. TLS is the relatively newer version when compared to SSL, SSL is the older encryption protocol.
