Chilean earthquake prompts Tsunami alert throughout the Pacific

A low-level Tsunami warning is in effect for the Point Roberts area. NOAA Our risk is considered to be fairly low but we should monitor the effect of this event as it proceeds throughout the Pacific region today. Hawaii is under a moderate danger warning and coastal regions in that state are being evacuated. Watch Live Streaming Earthquake Coverage here.

From NOAA:

...A TSUNAMI ADVISORY IS IN EFFECT WHICH INCLUDES THE
   COASTAL AREAS OF CALIFORNIA - OREGON - WASHINGTON - BRITISH
   COLUMBIA AND ALASKA FROM THE CALIFORNIA-MEXICO BORDER TO
   ATTU ALASKA...

RECOMMENDED ACTIONS
 A TSUNAMI HAS BEEN GENERATED WHICH COULD IMPACT THE ADVISORY
 REGIONS LISTED IN THE HEADLINE. PERSONS IN LOW-LYING COASTAL
 AREAS SHOULD BE ALERT TO INSTRUCTIONS FROM THEIR LOCAL EMERGENCY
 OFFICIALS. EVACUATIONS ARE ONLY ORDERED BY EMERGENCY RESPONSE
 AGENCIES.
 - PERSONS IN TSUNAMI ADVISORY AREAS SHOULD MOVE OUT OF THE
   WATER... OFF THE BEACH AND OUT OF HARBORS AND MARINAS.

 What should you do if a dangerous tsunami will reach our area.

Sea level readings  confirm that a Tsunami has been generated which could cause widespread damage. Authorities should take appropriate action in response to this threat. 

A Tsunami is a series of waves and the first wave may not be the largest wave. Heights cannot be predicted and can vary significantly along a coast due to local effects. The time from one wave to the next can be five minutes to an hour and the threat can continue for many hours as multiple waves arrive.

For all areas- when no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed

Danger to boats and coastal structures can continue for several hours due to rapid currents as local conditions can cause a wide variation in tsunami wave action. The all clear determination must be made by local authorities. Estimated initial tsunami wave arrival times at forecast point within the warning and watch areas are given below. Actual arrival times may differ and the initial wave may not be the largest. 

Tsunami Advisory Expanded for Entire US.-Canada West Coast from California and Alaska, The Tsunami Warning continues for the Pacific Basin. Estimated travel times for the tusnami are available from the West Coast/Alaska Tsunami Warning Center.

The following list gives estimated times of arrival for locations along the North American Pacific coast from a tsunami generated at the given source location. The list is ordered by arrival time starting with the earliest. Since tsunami speed is directly related to water depth, tsunami ETAs can be computed independent of tsunami amplitude.

THE LISTING OF A TSUNAMI ARRIVAL TIME BELOW DOES NOT INDICATE A WAVE IS IMMINENT.

The listed arrival time is the initial wave arrival. Tsunamis can be dangerous for many hours after arrival, and the initial wave is not necessarily the largest. extract: from this NOAA link

PREPARE YOUR  FAMILY

An emergency supply kit should be prepared well in advance of the tsunami's estimated arrival. The emergency kit provisions should include food, water, clothes, blankets, and warm bedding. Pack non perishable food in air tight containers. Any medications needed should be included in the emergency supply kit. First aid supplies, such as antibiotic ointment, bandages, a pain reliever (Aspirin, Tylenol, Ibuprofen). Drug stores often carry first aid kits with a package of supplies to use in case of basic emergencies.

Provisions should include enough supplies to last three days for each member of the family. If possible, have supplies ready for a longer period of time, because isolation could last for up to seven days and the family could be living off of the provisions, even if they do not have to leave the home.

The American Red Cross recommends the following provisions, as a minimum.

• Non perishable food (three to seven day supply)
• Flashlight
• Battery powered radio
• Extra batteries
• First aid kit
• Medical supplies and medications
• Personal hygiene items (soap, toothpaste, toothbrush, hand wipes, saniitzer)
• Copies of personal documents (proof of address, insurance policy in, birth certificate, passports, medication list, deed to home, proof of address)
• Cell phones with chargers
• Family and emergency contact information
• Extra cash
• Emergency blanket
• Maps of area
