As you may have seen in the news, Chile had a big earthquake a few hours ago. Experts at the Pacific Tsunami Warnings Center are currently evaluating to see if Hawaii is to expect a tsunami sometime early morning on April 2nd. Please check the local news for up-to-date information.
This is a good time to review what to expect in case of a tsunami and what to do. A year ago I wrote this post on tsunami awareness. I thought this is a good time to refresh our memories…
April is Tsunami Awareness Month
Tsunamis are caused by displacement of ocean water, usually by earthquakes. There are two types of tsunamis – those caused by a local earthquake and those caused by earthquakes far away.
If it is a local earthquake and you are at the beach, there will be little time for warning. Here are the signs to look for:
If you experience any of these while at the beach, you should move away from the beach to at least 100 feet above sea level (one mile inland or in a pinch at least to the fourth floor of an apartment building). If it is a local earthquake, the tsunami waves could arrive within minutes.
If it is a far away earthquake, there will be more warning time. The NOAA Pacific Tsunami Warning Center tracks all earthquakes and monitors their DART buoys for possible tsunamis. Should there be a tsunami headed our way, they issue alerts via local media (radio, local TV stations etc). You can find warnings on facebook and twitter (try hashtag #hitsunami).
The most obvious warning will come from the tsunami sirens located wherever there is danger of flooding (if you are in a remote location, there may not be a siren). When there is a tsunami warning, these will start wailing (steady three minute tone), fortunately not non-stop but at regular intervals (note: there is amonthly emergency systems test the first day of every month at 11:45 – don’t panic!) If the sirens start wailing, listen to the local news and follow their directions. Warnings will always tell you when the first tidal wave is expected to arrive. Please listen to these warnings and obey them.
How do you know if you are in an evacuation area? Here are two evacuation maps for Kihei/Wailea, you can also look on the County of Maui website in the phone book (we have them in all our condos). If you are staying in our Kihei Surfside and Sugar Beach condos, you are in the evacuation area. If you are staying at our Maui Kamaole or Palms at Wailea condo, you are NOT in the evacuation zone (you do not need to evacuate).
If you need to evacuate:
If you are not in the evacuation zone:
It will be very difficult to find local Maui specific tsunami information. Most of the news will be about Oahu (this is frustrating).
Please do not put your life and that of others (who may have to save you) at risk by going to the beach to watch!
Here is a cute and yet informational video from San Diego County explaining about tsunamis (use this link if it doesn’t load).
