The study describes the TS-HKMSDD system, which saw a weak tsunami pass through Tokyo Bay in September 2021, caused by a typhoon approaching Japan from the south.
Researchers have discovered a new approach to tsunami detection, which is to track muons. Science Alert writes about it.
It has been noticed that muons are elementary high -energy particles created by cosmic rays coming from space. They are ubiquitous in the environment and can pass without harming almost anything.
However, they can be partially removed in their way by large natural forces, including tsunamis.
To determine the movement of muons, an incredibly sensitive instrument-TS-HKMSSD-is required. He first saw tsunami waves through muon ripples.
“The Tokyo Bay Hyperkilometer Underwater Depth Detector is the first underwater muon observatory in the world to detect a variety of muon activity during a tsunami,” said geophysicist Hiroyuki Tanaka from the University of Tokyo in Japan.
It is emphasized that this variation corresponds to ocean currents measured by other methods. Combining these readings means that muographic data can be used to accurately model sea level changes, surpassing other methods that have disadvantages.
A new study describes the TS-HKMSDD system that detected a weak tsunami that passed through Tokyo Bay in September 2021, caused by a typhoon approaching Japan from the south. As the ocean expanded, the number of muons changed slightly, scattering throughout the volume of water.
Based on this, the researchers suggest the same tools can be installed in other tunnels in tsunami-prone areas and used in conjunction with equipment such as sea level sensors as part of early warning systems. .
“The muon detectors that make up the TS-HKMSSD are really small, about two meters long. Currently, 20 of them are located next to the Tokyo Bay road tunnel, working together to create a common system. Such a system can be used not only to detect upcoming tsunamis, but also to search for natural gas reserves and identify patterns of ancient earthquakes.
Recall that earlier the Japanese technology company Fujitsu announced the opening of global access to a powerful supercomputer.
