Oregon is trying to avoid environmental disasters caused by earthquakes

A river burning with millions of gallons of oil spills, jet fuel and petrol. The worst environmental disaster ranking in the United States. There is no state fuel trying to recover from a major earthquake.


Scientists say Oregon faces a potential nightmare scenario unless work is done to strengthen Oregon’s main fuel A storage facility for large earthquakes that will come sooner or later.

Over 90% of the state’s liquid fuel is stored in the Critical Energy Infrastructure Hub along the Willamette River, 6 miles (10 km) in northwestern Portland.

This week, Oregon Legislatures have begun taking steps to make the facility’s aging storage tank owners and operators earthquake-resistant.

new Report Commissioned by the City of Portland and Multnomah County, the hub has been built on earthquake-liquefied soil, causing water-saturated sediments to temporarily lose strength and function as fluids.

According to state reports, the industrial area has 46 large ground fuel tanks, liquefied natural gas storage facilities and pipelines. Some fuel tanks are more than 100 years old and most were manufactured at least 50 years ago.

The study estimated that a major earthquake along the Cascadia subduction zone would eject 95 to 194 million gallons (432 to 882 million liters) of fuel from the tank. It flows from the Willamette River into the nearby Columbia River, reaching the Pacific Ocean about 100 miles (160 kilometers) northwest, unless contained.

Predicted damage is equivalent to the largest environmental disaster in US history, with BP’s Deepwater Horizon drilling rig exploding in 2010, spilling at least 134 million gallons (609 million liters) of oil into the Gulf of Mexico. is.

“Fuel release is likely to cause an explosion or fire,” Oregon researchers write. “If a fire spreads to other facilities, it poses a tremendous threat to human life, safety, physical structure and natural resources.”

California is especially known for earthquakes along the San Andreas Fault. However, experts predict that one of the world’s largest earthquakes can occur at any time along the Cascadia subduction zone that runs from offshore Northern California, Oregon, and Washington to Canada. The last Cascadia earthquake occurred in 1700 and is estimated to have a magnitude of 9.

Oregon authorities are aware of the threat and are taking steps to mitigate it.

Held annually, the Great Oregon ShakeOut Day encourages Oregon residents to learn how to respond to earthquakes. Governor Kate Brown frequently reminds people to maintain an emergency kit with at least two weeks’ worth of food, water and other essentials. Tsunami warning signs are scattered on the coastal highways.

In 1995, the Legislature banned the construction of certain emergency and other public facilities in tsunami inundation areas. However, it abolished this measure in 2019 after coastal legislators said that without a new emergency service building, coastal residents and businesses would not be able to take out asset insurance that would reduce the value of their assets.

Last year, Oregon participated in an early warning system operated by the United States Geological Survey. Use seismograph sensors to quickly detect serious earthquakes and alerts to your smartphone so people can find a cover. Washington and California also use this system.

According to Chris Goldfinger, an earthquake expert and professor at Oregon State University, at least a magnitude 7 earthquake is 37% likely to occur off the Oregon coast in the next 50 years. He said a magnitude 9 quake is 10% to 15% more likely to occur during that period. The largest earthquake ever recorded was magnitude 9.5 and struck southern Chile in 1960.

Senator Michael Dembrow, from Portland and chief sponsor of the bill, said at a hearing of the Senate Energy and Environment Commission on the bill, “We are living on a time bomb.”

Every time he drives a storage tank, Denbroff has to ask himself, “I have a nightmare vision of an earthquake, and why did the elected officials ignore the warning?” Stated.

“If that happens, how do we live with ourselves?” He asked a fellow lawmaker. Twenty other people joined him to sponsor the bill.

Leaders of the American Society of Civil Engineers’ Oregon branch testified that making the facility earthquake-resistant is very important. They are, big earthquakeFuel is needed to power generators, equipment, and vehicles for rescue and emergency personnel.

All Jet fuel For Portland International Airport, it is stored in the Critical Energy Infrastructure Hub. Without it, planes that bring aid to Oregon would not be able to refuel.

Mike Harryman, appointed by the Governor to be Oregon’s first state resilience officer and prepared for Cascadia earthquakeOregon said it would feel three punches: the quake itself, the tsunami, and the “disaster” at the fuel hub.

“So far, we are unaware that vibration control has been initiated on-site by either the owner or the operator,” he told the hearing.

This bill is with the owner or operator of bulk oil Liquid fuel The terminal will carry out a seismic vulnerability assessment by June 1, 2024 and submit it to the Oregon Department of Environmental Quality. The Oregon Department of Environmental Quality reviews and approves them. The owner and operator then implement a seismic risk plan approved by the department.

“How they work and what schedules aren’t clear yet,” Denbroff said in an email.

Jessica Spiegel of the Western States Petroleum Association, a non-profit organization representing companies involved in the oil industry in five western states, including Oregon, has a large fee for the bill, but federal funds are available to mitigate them. He said he had sex.

She said that pricing is set and that “some understanding of the state’s business needs” should be taken into account.


When “Big One” comes, the earthquake warning system will be activated in Oregon.
