JoeRobe writes "Researchers at UCSC have simulated a possible outcome of an impact by asteroid 1950DA when it passes near us in the year 2880. Note that there is a 0.3% chance of impact during that encounter. In the event that it impacts in the Atlantic, they predict that the '60,000 megaton blast' would create 400 foot waves along the east coast. In addition to an assessment of the danger, their studies point out the resulting geologic features that we should be looking for now, which would indicate where and when such impacts have occured in the past."
