Nothing happens til the one minute mark. But the pressure wave is immense! Found on http://twentytwowords.com/massive-landslide-swallows-10-cars-as-baltimore-residents-watch-in-shock/

Several streets were closed late Wednesday afternoon. St. Paul and Charles are major thoroughfares that are generally crowded during both the morning and evening commutes. The neighborhood is largely residential rowhouses. Traffic was reported to be snarled in the area of the collapse and downtown.

Brennan said no houses were damaged, but fire officials said many residents living along East 26th Street were ordered to leave until building inspectors can assess their properties.

Photographs show a wide area of destruction in what appears to have been a landslide. The railroad tracks are covered with water, dirt and more than a half-dozen cars that went down the embankment. Baltimore officials said CSX has suspended rail service through the city.
