Monday, March 11th marks the 8th anniversary of the Great Japan Earthquake and Tsunami, (Sometimes called the Great Tōhoku Earthquake and Tsunami). The dramatic and startling images, covered on live television, are indelibly chiseled into the subconscious of everyone who watched the events unfold in real time, as the most disaster prepared country in the world, faced the wrath of a magnitude 9.1 earthquake, the 4th largest ever recorded and a series of massive tsunami waves.
Earthquake Early Warning
At 2:46 pm on Friday, March 11, 2011, the Japanese Earthquake Early Warning System received an indication of a major earthquake fault rupture, 45 miles east of the Tōhoku region and 231 miles northeast of Tokyo. Within seconds, the Earthquake Early Warning System transmitted a warning message to the people in and surrounding the Tohoku region of Japan, indicating a large earthquake had occurred. People began receiving the warning message, via a cell phone text message, as local television and radio stations began broadcasting the earthquake warning. As a result of the Early Earthquake Warning, elevators in Tokyo moved to the closest floor and opened to allow passengers to evacuate and take protective actions. Factory assembly lines were automatically shut down and the Tōhoku Shinkansen high-speed bullet trains, travelling nearly 200 mph, were automatically prompted to slow and stop, potentially saving thousands of passengers from injury. Just 5-15 seconds after the alert, coastal areas of the Tōhoku region closest to the rupture, began to violently shake, while a more devastating disaster was fast approaching – a series of massive tsunami waves.
As of September 2018, data indicates 15,896 people were killed and 2,536 are still missing from the magnitude 9.1 earthquake and resulting tsunami. 58,000 of the coastal citizens who evacuated their homes remain evacuated 8 years later, while 5,623 still live in prefabricated temporary housing. The economic damage from the disaster event is estimated to be near $360 billion. As of Spring 2017, seven cities, towns and villages have been deemed “difficult to return” zones by the Japanese government because of increased radioactivity in those areas, due to the Fukushima Daiichi nuclear disaster that occurred during the tsunami.
Is Knowing What to Do Enough?
We can never be prepared enough for disaster, nor should we take any of them lightly. Any effort toward disaster preparation will help reduce the impact the event will have upon your family, business and community.
Local, State and Federal Efforts to Reduce Disaster Impacts
Efforts are increasing in coastal communities to build Tsunami Vertical Evacuation Structures, like the Ocosta Elementary School, in Grays Harbor County and the planned Vertical Evacuation Tower, in Tokeland, by the Shoalwater Bay Indian Tribe.
Unreinforced Masonry Buildings are being identified throughout Washington as local governments are working with owners to assist in ways to retrofit the buildings, preserving the historic facades, while protecting people from an exterior wall collapse during earthquake.
Earthquake Early Warning is being developed and is becoming more robust throughout the Pacific Northwest and in Washington State. Pilot users are being sought in schools, business and industry to begin implementation of the ShakeAlert Earthquake Early Warning System. Currently Earthquake Early Warning messages cannot be sent to individuals, because the current process to send the warning to individual cell phones is far too slow. Work is ongoing, toward the development of a process that can transmit the warning to everyone, much more quickly and prior to the earthquake shaking at your location.

On this day in the year 2001, the pacific northwest experienced the Nisqually Earthquake, a 6.8 magnitude, at 10:54 am. Following this event, many mitigating activities started to take place.
Today, the region will soon have an early earthquake warning system, increased seismic standards are built into our building codes, many critical infrastructure buildings have been retrofitted to newer seismic standards, we have a new Highway 99 tunnel to replace the damaged Seattle viaduct and increased planning and mitigating activities to prepare for the next day the earth shakes.
Here are some articles highlighting this historic day.
The purpose of this white paper is to summarize the scientific evidence and professional opinion concerning earthquake protective actions that can be taken by the public immediately before the ground starts to shake, in as many scenarios as possible.
Although the advent of Earthquake Early Warning (EEW) in the U.S. provides a tremendous opportunity to reduce human, property, and economic losses, there are substantial, critical gaps in research needed to help guide the design and implementation of the U.S. system, ShakeAlert. Scholars and practitioners have amassed decades of research about actions to take during earthquake shaking; however, very little research has been conducted specifically on the unique context of EEW.
Due to the gaps in research around EEW, this white paper focuses on the strength of evidence that supports (or fails to support) general earthquake protective actions. The authors primarily summarize content from two key reports by FEMA and GHI, integrating dozens of additional literature sources and input from subject matter experts. The white paper examines more than a dozen protective actions, from “Stay Indoors” to “Pull Over and Stay in Vehicle”, noting whether each action is recommended, recommended with caution, or not recommended for inclusion in public education campaigns.
To help guide emergency managers in their support of ShakeAlert, existing research must be assessed for its appropriateness in an EEW context, and the need for additional research to fill critical gaps in light of EEW implementation should be identified and conducted. In addition, crucial to this effort is having a clear understanding of the evidence base and strength of support for recommending different protective actions in various settings, including whether support is based on research findings, expert opinion, or simply on informed practice.
