Professor Honored for Seismic Safety Contributions

May 16, 2017 3:42 pm

Tsunami expert Lori Dengler has just been named the recipient of the 2017 Frank Press Public Service Award for her “exceptional leadership as a scientist, writer, educator, communicator and advocate of tsunami research and preparedness,” according to a Humboldt State University announcement on Friday. Cal OES’s Kate Long says Lori is part of the Cal OES Earthquake and Tsunami Program through a contract with Humboldt State University (NTHMP-funded).  RCTWG is also one of the founding organizations making up the Earthquake Country Alliance (ECA); the cross-sector, cross-region networking coalition Cal OES organizes and supports; ECA/RCTWG is pivotal in grassroots organizing for tsunami awareness week and the great California shakeout. RCTWG has also served as the model by which other regional ECA Group’s have formed. CAL OES Eq/Tsu Program was also one the three organizations that nominated … continue reading »

¿Qué Haría Usted Si Un Tsunami Llega a California?

Mar 30, 2017 4:44 pm

California es tierra de terremotos. Con los terremotos en California y en otras partes del mundo, se presenta riesgo de tsunami. Si un tsunami llega a la costa de California, que harías? Si las condiciones presentan riesgo de tsunami a la costa de California, manténgase a salvo y aléjese de las olas. Conocer como preparar para un tsunami y como reaccionar si uno llega es especialmente importante para los que viven o trabajan cerca de la costa. También es importante para las personas que visiten a la costa.

Tsunami Preparedness – Saving Lives and Protecting Property

Ryan Arba is the branch chief for the Cal OES Earthquake and Tsunami Program.   In this episode, Ryan talks about the program, its federal partner NOAA and the focus of this year’s Tsunami Preparedness Week events.

The California Governor’s Office of Emergency Services, Earthquake, Tsunami and Volcano Program is continuously researching, learning, and collaborating with science, industry, and academic experts to develop and confirm the latest, best available knowledge base to help make California’s residents and visitors safer in the event of tsunamic activity. By mapping potential inundation and evacuation areas, providing assistance in response and evacuation planning, implementing outreach, education and warning signage at the coast, as well as determining ways to improve preparedness and resilience of California’s ports and harbors, our staff strives to ensure everyone on the coast remains safe before, during and after the next tsunami.

Shawn Boyd & Ryan Arba In-Studio

Catastrophic tsunamis are rare, we may have a tendency to get complacent and think that one will never happen while we’re at the beach. However, every coastline in the world is vulnerable to a tsunami. Although a tsunami cannot be prevented, you can diminish adverse impacts through community preparedness, timely warnings and effective response.​​​

​California’s 2017 Tsunami Preparedness Week is March 27-31. On March 29, Cal OES, the California Geological Survey (CGS) and the NWS will conduct a conference call with emergency managers from counties along the coast to test several aspects of the tsunami response, including the ability of the National Tsunami Warning Center (NTWC) to send and coast emergency organizations to receive specific tsunami alert messages.

During the conference call, representatives from the NTWC, Cal OES and CGS will also test their ability to accurately calculate and verify information contained in draft Tsunami Evacuation Playbooks that will be used by local emergency to determine if an evacuation is necessary and, if show, for how big of an area. The test also allows emergency managers from coastal communities to confirm their ability to receive playbook-related information, test their ability to make decisions regarding evacuation, and as well as to test their abilities to communicate information to port and harbor officials as well as to test their reverse notification and other warning systems reaching people in coastal hazard areas.

Drilling Down into Tsunami Preparedness Week

Mar 27, 2017 6:12 pm

This week (March 27 – 31) is Tsunami Preparedness Week in California. Whether you live along the coast, have family and friends there, or just visit on occasion, it’s important to know what the hazards are and how to keep you and your family safe.  Cal OES has put together an OES News In-depth report to shed a little light on tsunami safety and to show you some of the latest “ground breaking” research that’s gone into understanding the connection between earthquakes and tsunamis.

A Look Back at the 1964 Alaska Earthquake and Tsunami

Mar 9, 2017 4:47 pm

The most powerful earthquake in United States history was recorded 53 years ago this month. At 5:36 p.m. local time, a magnitude 9.2 earthquake occurred in the Prince William Sound region in Alaska on March 27, 1964.

In all, 139 people were believed to have died as a result of the earthquake. Fifteen died from the earthquake alone, while 106 died in Alaska, 13 died in California and five died in Oregon all related to tsunamis.

In addition to a tectonic tsunami, about 20 smaller and local tsunamis occurred. Smaller tsunamis were created by submarine and subaerial landslides, and tsunami waves were measured in over 20 countries including Peru, New Zealand, Papua New Guinea, Japan and Antarctica.

The earthquake rupture started approximately 15 miles beneath the surface, with its epicenter about 6 miles east of the mouth of … continue reading »

Inside the Eye of the Storm: The Cal OES/NOAA Tsunami Exercise

Apr 23, 2015 3:11 pm

NOAA and the Calif. Office of Emergency Services (Cal OES) conducted a test of the tsunami warning communications system on March 25th in coastal areas of central and southern California.

NOAA’s National Weather Service Offices in Monterey, Oxnard and San Diego broadcast the “Required Monthly Test,” and was also broadcast on NOAA Weather Radio All Hazards, local television and radio stations. Cal OES collaborated with 20 coastal counties in addition to NOAA and the Civil Air Patrol to carry out the annual Tsunami Warning Communications Test. This year the weather cooperated with exercise and allowed the Civil Air Patrol to participate in a flyover in Mendocino, Humboldt and Del Norte counties. During the test, the CAP tested their capability to alert the public of a simulated tsunami warning using an on-board public address system.

There were three … continue reading »
