Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...

The tsunami created over 300,000 refugees in the Tōhoku region of Japan , and resulted in shortages of food, water, shelter, medicine and fuel for survivors. 15,900 ...
The most obvious was that in tsunami-prone areas, a power station's sea wall must be adequately tall and robust. [44] At the Onagawa Nuclear Power Plant , closer to the epicenter of the 11 March 2011 earthquake and tsunami, [ 219 ] the sea wall was 14 meters (46 ft) tall and successfully withstood the tsunami, preventing serious damage and ...
A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
Tsunami modelling executed by the University of Tokyo and Building Research Institute of Japan computed the tsunami to be 3.6 m (12 ft) in Suzu; 3 m (9.8 ft) in Noto; 2.5 m (8 ft 2 in) in Shika and 2 m (6 ft 7 in) in Jōetsu, Niigata. [101] Flooding by the tsunami exceeded 4 m (13 ft) along the east and western part of the peninsula.
The earthquake occurred on Tuesday, August 16, 2005, and affected Japan's northeastern coast. It triggered a tsunami warning, and buildings shook 200 miles away in the capital, Tokyo. It was initially estimated to have a moment magnitude of 6.8, and the United States Geological Survey later declared it as a 7.2. [1]
