The tsunami took just over 4 hours to travel over 1,000 miles (1,600km) to Cornwall in the United Kingdom. The last and smallest event in the series occurred upslope relative to the mainshock and generated the largest tsunami. A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. Consider backup or redundant systems where possible, in conjunction with service providers. Thus, even when the project itself is damaged by the tsunami, it may not function. The storm continued on to trace the southeastern United States coast, just clipping the Outer Banks of North Carolina, before racing into Canada late Saturday afternoon with the equivalent of Category 2-strength storm winds. Independent wireless communication, such as VHF radio may be vital at a time of crisis. Consider planning for rapid re-instatement of these services to the project. In the Pacific, a 1998 earthquake caused an undersea landslide that generated a 23-foot tsunami that destroyed coastal villages and killed more than 2,000 people. Services may be made more resilient by incorporating higher engineering specifications designed for tsunami scour, lateral pressure, buoyancy, debris impact and fire. If the consequences of tsunami damage are unacceptable consider moving the project. On 10 February 1797, a massive earthquake estimated to be approximately 8.4 on the moment magnitude scale struck Sumatra in Indonesia. The fault zone that caused the tsunami was roughly 1300 km long, vertically displacing the sea floor by several metres along that length. A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water.
