![]() Researchers believe similar fluid seep sites may exist nearby, but they are hard to detect from the ocean’s surface. Furthermore, these plastic hooks are so thick that they cause the picture to lean forward at an extreme angle, especially smaller pictures. This is the first known site of its kind. They still allow the picture to jump around a lot, potentially causing other problems (I tend to put dabs of quake putty at the lower corners to stabilize them). These strike-slip faults, where sections of ocean crust and sediment slide past each other, exist because the ocean plate hits the continental plate at an angle, placing stress on the overlying continental plate. Instead, they occur near vertical faults that crosshatch the subduction zone. ![]() The new seeps are unrelated to geologic activity at the nearby seafloor observatory the cruise was heading toward, says Evan Solomon, associate professor of oceanography. Calculations suggest the fluid is coming straight from the Cascadia megathrust, where temperatures are an estimated 150 to 250 degrees Celsius (300 to 500 degrees Fahrenheit). Observations from later cruises show the fluid leaving the seafloor considerably warmer than the surrounding seawater. The feature was discovered by Brendan Philip, then an undergraduate student and now a White House policy adviser. Earthquakes strike suddenly, without warning and can occur at any time of. As the team explored the area with an underwater robot, they found the bubbles were just a minor component of warm, chemically distinct fluid gushing from the seafloor. The Great ShakeOut Earthquake Drill: Drop, Cover and Hold On. Sonar showed unexpected plumes of bubbles about three-quarters of a mile beneath the ocean’s surface. I took a gob of it and dabbed the ones on the wall and they came off quite easily. When I removed it, there was 4 gobs of putty on the wall. The team made the discovery during a weather-related delay for a research cruise aboard the RV Thomas G. I just removed a picture that had been secured to the wall with earthquake/museum putty. They think the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, helping regulate stress on the offshore fault. ![]() 25 in Science Advances, describes the unique underwater spring the researchers named Pythia’s Oasis. A recent UW-led study exploring the seafloor about 50 miles off Newport, Oregon, discovered seeps of warm, chemically distinct liquid shooting up. The Cascadia Subduction Zone-the eerily quiet offshore fault that threatens to unleash a magnitude-9 earthquake in the Pacific Northwest-holds many mysteries.
