Current Observation

 

*************************************

1.What is a No Tsunami Information Statement –  No Threat
A  tsunami information statement ( No Threat) is issued to the public that an earthquake has occurred but there is no threat of a destructive tsunami and to prevent unnecessary evacuations as the earthquake may have been felt in coastal areas.

2.What is a Tsunami Watch : Tsunami Watches are issued as a means of providing an advance alert to areas that could be impacted by destructive tsunami waves.
Tsunami Watches are updated at least hourly to continue them, expand their coverage, upgrade them to a Warning, or end the alert as a NO THREAT

3.What is a Tsunami Warning : Warnings are issued due to the imminent threat of a tsunami from a large undersea earthquake or following confirmation that a potentially destructive tsunami is underway.Warnings are updated at least hourly to continue, expand, restrict, or end the warning.

TSUNAMI....?

  1. Any unusual change in sea level.
  2. A ROARING noise.

Tsunami waves are more than one wave, are more powerful than the same size beach waves, with the first wave not necessarily being the largest. Most tsunamis have two or three large waves, and there may be tens of minutes between the arrival of each one.Low-level effects may be observed in neighbouring coastal areas like strong currents and changing tide levels. People are advised to take care.Upon noticing the warnings signs: RUN to a safe place. Do not wait to be told. Do not wait until you see the wave - that is too late because the wave travels faster than you can run.

YOU ARE SAFE FROM THE WAVE AS LONG AS YOU ARE SEVERAL KILOMETRES FROM THE WATER'S EDGE OR ARE ON HIGH GROUND.


WHAT TO DO?

PREPARE FOR A TSUNAMI

  • Tsunamis often happen suddenly, the community must be aware of the warning signs.
  • Coastal communities and schools should plan for the tsunami. Preparation of areas and escape parts should be on higher grounds at least a few kilometres from the coast.
  • Have disaster supplies on hand torch, radio, extra batteries, medicine, food and water supplies. Develop emergency plan and post for disaster meeting place.

DURING A TSUNAMI

  • Listen to radio/TV for tsunami warnings, evacuate and seek higher grounds immediately if tsunami warnings arises.
  • Village leaders and families should activate emergency response plans. Ring church bells, blow conch shells or beat
  • If you are on a boat off shore, do not return to shore - the vessel is safe in the open sea.
  • During a tsunami emergency, police and other emergency organisations will try to save your life. Give them fullest cooperation. A tsunami is not a single wave-it is a series of waves, so stay out of danger areas for at least 2-3 hours.
  • If you are near the sea and feel the shaking of a strong earthquake that lasts more than 20 seconds, if the sea goes quickly dry, or you hear a loud hissing sound, you may only have minutes until a tsunami arrives and must move to higher ground. Do not wait for an official tsunami warning
  • People close to sea, beach or coastal rivers are strongly advised to move to higher ground and continue to listen for information updates
  • If you cannot move to higher ground take shelter in the upper storey of the strongest building available
  • Take only essential items like radio, mobile, matches, torch, knife, food, water, important papers,  important medicine
  • DO NOT RETURN to your villages straight after the Tsunami Warning Cancellation but REMAIN ON THE SAFE AREAS for at least three hours or until an ALL CLEAR MESSAGE is issued
  •  If you are in an urban area move into a clear area away from overhead hazards like trees, buildings and windows in case of further earthquakes
  • Move away from cliffs in case of landslides
  •   Boats already in deep water should stay in deep water until further advised

AFTER A TSUNAMI

  • Listen to your radio for advice and updates.
  • Help trapped or injured people.
  • Stay out of damage buildings. When returning to your homes enter with caution - check for gas leaks, electrical shorts and live wire.
  • A small tsunami at one point on the shore can be extremely large a few kilometers away. Don't let the modest size of one make you lose respect for them all.

For urgent assistance call 955 (NEOC) or 933 (SI Meteorology) or 999 (Police), or 977 (Marine), or your nearest Provincial Disaster Emergency Operations Centres or your nearest Police Station.
