A 7.7 magnitude earthquake rumbled moments ago near the deep-water Marianas Trench. The Pacific Tsunami Center says that no Pacific-wide tsunami was generated by the event and there is no tsunami threat to Hawaii.
No word on damages to any land area.
EVENT: The Pacific Tsunami Warning Center has ISSUED a TSUNAMI WATCH for the Hawaiian Islands effective at 9/16/2015 at 1:04 p.m(HST). If tsunami waves impact Hawaii, the estimated earliest arrival of the first wave is: Thursday, September 17, (Thursday) at 2:28 a.m.
EFFECTS: An earthquake occurred of the coast of northern Chile on 9/16/2015, at 10:59 a.m. with a preliminary magnitude of 7.9 on the Richter Scale.
Based on all available data from the Pacific Tsunami Warning Center a tsunami may have been generated by this earthquake that could be destructive on coastal areas even far from the epicenter. An investigation is underway to determine if there is a tsunami threat to Hawaii.
PRECAUTIONARY MEASURES: PERSONS IN LOW-LYING AREAS SHOULD BEGIN EMERGENCY PREPARATIONS. PLEASE REFER TO THE FRONT YELLOW SECTION OF THE TELEPHONE BOOK FOR PREPAREDNESS INFORMATION AND EVACUATION AREAS. PREPARE YOUR “GO KIT” IF YOU NEED TO EVACUATE TO HIGHER GROUND. BE PREPARED TO EVACUATE WHEN ADVISED/ORDERED BY CIVIL DEFENSE.
INFORMATION: Maui Civil Defense Agency will continue to monitor the situation. Please listen to your local radio and TV stations.
Pre-recorded advisories and notifications are available 24-hours a day on the Maui County Automated Information System (AIS) by calling 986-1200. This same notification can be found on the Maui County website at mauicounty.gov.
There is no Pacific-wide tsunami threat after a magnitude 6.8 earthquake this morning in the Fiji Islands.
The quake struck at 5:53 a.m. HST about 100 miles south-southwest of Sigave, Wallis and Futuna, Fiji. There have been no reports of injuries or serious damage.
Washington, D.C. – Today, the Senate Commerce Committee voted to advance the Tsunami Warning, Education, and Research Act of 2015, H.R. 34. U.S. Senator Brian Schatz (D-Hawai‘i) offered an amendment, adopted with bipartisan support, which would improve tsunami research by including key historical data and strengthen preparedness programs in coastal communities.
“As an island state with over 700 miles of coastline, a reliable tsunami warning system is critical to protecting our communities. We must do all that we can to be better prepared for an event that affords only minutes or hours for people to respond,” said Senator Schatz. “My legislation will strengthen our tsunami detection, forecast, warning, research, and mitigation program to better protect Hawai‘i’s communities and save lives.”
The Schatz amendment made the following key improvements:
Major tsunami events are infrequent enough that relying on modern records alone could easily overlook past tsunami threats revealed in the geological record. Having a thorough understanding of the full range of tsunami threats a community faces is critical for resilience planning.
The existing network of tsunami buoys provides an essential first line of defense to detect and forecast tsunami, but their scope is limited by the costs of deployment and maintenance. In order to create a more robust system with limited resources, the amendment encourages NOAA to explore how tsunami detection and research sensors could be deployed along with telecommunications cables.
Evacuating from the lower floors of a building to its upper floors is considered to be not only viable, but the best practice when a tsunami is only minutes away. Just as the high density of tall buildings in a typical downtown district can create a canyon effect to amplify the force of winds, understanding their effect on strength and current of flood water may help to ensure the viability of evacuating to the upper floors of a building.
More and more communities understand the necessity of resilience planning at the whole-community scale, but the structure of federal government is not always nimble enough to adapt to support local needs. The amendment language authorizes public-private partnerships to address coastal resilience, together with the formation of 501(c)(3) foundations in order to accept and use non-federal funding to address tsunami preparedness.
A 6.0 earthquake off the coast of Panama at 6:40 p.m. HST has not generated a pacific-wide tsunami. It was the third temblor of magnitude 5.5 or higher in the last two days in that region. An Earthquake “Watch” – essentially for information purposes only – has been issued for the region.
The US Geological Survey also notes that no tsunami activity has been detected by deep water buoys in the so-called “ring of fire.” No further bulletins are expected on this incident.
The magnitude of that overnight earthquake has been upped a tick. Originally reported as a 4.1, the adjusted number is now 4.2 on the Richter Scale according to the U.S. Geological Survey’s Hawaiian Volcano Observatory on the Big Island.
The temblor occurred at 2:37 a.m. today and was felt across Maui County. There were no aftershocks and no tsunami threat was issued by the Pacific Tsunami Center on O’ahu.
Earlier Friday the center said it estimated the quake at 4.1 which was reported at 2:37 a.m. Friday in the “deep ocean” southwest of Lanai.
But the USGS said although the magnitude was initially estimated at 4.0, a more detailed seismic analyses resulted in a final magnitude of 4.2. It occurred in the ocean about 4 miles deep and 34 miles west-southwest of Maunaloa, Molokai.
