Scientists are predicting in a new model what would happen if a tsunami hit Western Washington.

The simulator shows what would happen if a 9.0 earthquake hit the Cascadia subduction zone - also known as “the big one.”

The study estimates that the earthquake would generate a tsunami capable of submerging coastal areas as well as most of the shoreline in Puget Sound with several feet of seawater.

Three of the Sumatra earthquakes of September 2007 had a magnitude of 7 or above and were part of a series of megathrust quakes that hit the Sunda Trench off the coast of Sumatra, Indonesia. There were several tsunami warnings sent out for the region. With a magnitude of 8.4, the strongest in the series ranks among the top 20 largest earthquakes ever detected by a seismograph.

The dead toll from a magnitude 7.2 earthquake in Haiti rose to 1,297 on Sunday, a day after the massive quake reduced thousands of buildings to rubble and sparked frantic rescue operations in front of a predicted storm downpour.

At least 5,700 people in the Caribbean island were hurt by the earthquake on Saturday, and hundreds more had to leave their damaged or destroyed houses. Some survivors had no choice but to wait outside in the stifling heat for assistance from overcrowded hospitals.

With the approach of Tropical Depression Grace, which is anticipated to make landfall in Haiti on Monday night, the destruction may soon get worse. Although Grace had lost some of its tropical storm intensity by Sunday, the U.S. National Hurricane Center warned that it still posed a risk of bringing heavy rain, flooding, and landslides.

The strongest earthquake to hit the United States in fifty years struck off the coast of Alaska on July 28 at 10:15 p.m. Alaska time. A medium-depth earthquake, the Chignik Earthquake measured around 28.5 miles deep.

The M7.6 Simeonof Island Earthquake, which erupted on July 21, 2020, was located around 45 miles from the Chignik Earthquake's location. Although the Chignik Earthquake was the deepest of the two, they both occurred along the boundary between the Pacific plate that was subducting and the North American plate that was superimposing. There are thousands of earthquakes per year in the seismically active Alaska Peninsula. The interface, also known as the Aleutian megathrust, is where the greatest earthquakes occur. This interface between the Shumagin Islands in the southwest and Kodiak Island in the northeast was ruptured by the M8.2 event. This portion of the interface was already fractured by the 1938 M8.3 earthquake.

The strongest of the series was a 2.79 magnitude shaker near SeaTac. While it was likely too small for people to feel, it did draw the attention of seismologists...

How Can I Avoid Hearing Loss Caused by Loud Noise?

The impact of noise on hearing varies with the volume (sound intensity) and duration of the noise (duration). The best protection is to stay away from noisy environments. Make sure you have proper hearing protection if you can't escape the noise.
