If disastrous waves are expected in coastal regions, JMA issues a Tsunami Warning/Advisory for each region expected to be affected based on estimated tsunami heights. In order to have information sources available at any time, Japan’s tsunami warning system gathers data from ocean-bottom tsunami sensors further offshore, GPS buoys, coastal-area tsunami meters, broad-band strong-motion seismometers and even DART buoys which are water-pressure gauges. Required fields are marked *. The tsunami early-warning system measures seismic signals during the first minute after an earthquake and feeds these into computer simulations. When I say slow, it’s just compared to their speed when crossing the ocean (up to 500 miles or 804 km), because they can go as fast as 30 miles (48 km) inland, according to the US National Tsunami Warning Center. “Ghost of the Tsunami” available on Amazon, https://www.youtube.com/watch?v=lAxxZkpV0HI, 2016/11/22 Japan earthquake and tsunami alert (w/ roughly translated English subtitles) (https://www.youtube.com/watch?v=lAxxZkpV0HI), https://www.youtube.com/watch?v=_oPb_9gOdn4, Tsunamis 101 | National Geographic (https://www.youtube.com/watch?v=_oPb_9gOdn4).
