It is also important to check that your urban growth and development projections do not conflict with neighboring jurisdictions and local governments in the area. â¢ Be sure to update your land use regulations to accommodate the new infill development that will result from implementation of the urban growth boundary.
An ocean earthquake commonly occurs between 200 and 1,000 years. As the pressure of floating plates bouncing against a continental plate rises, the continental plate starts pushing back. This causes an ocean floor island to recede underwater until the pressure is too great.
Earthquakes that generate tsunamis most often happen where Earth's tectonic plates converge, and the heavier plate dips beneath the lighter one. Part of the seafloor snaps upward as the tension is released. The entire column of seawater is pushed toward the surface, creating an enormous bulge.
