A second way natural disasters destroy internet connectivity is by severing submarine cables — fiber-optic cables placed on the ocean floor that provide international internet connection . A sequence of undersea earthquakes cut six out of seven international cables connected to that country and caused a tsunami that wiped out one of its cable and landing stations . The impact slowed or disabled internet connection for five days within the Asia-Pacific region as well as between the region and the United States and Europe
