Follow official evacuation orders: When a tsunami warning is issued, listen to local authorities and immediately evacuate to higher ground. Find high ground: If possible, move to the highest ground possible. Climb to the top of a hill or mountain, or seek shelter in a tall building. Stay away from the coast: Move at least …
Seismographs are instruments that measure and record seismic waves, which are waves of energy that travel through the Earth caused by movements of the Earth’s crust. Seismographs measure the amplitude, frequency and direction of the seismic waves. The data recorded by seismographs is used to study earthquakes, and to monitor large-scale earth movements.
Seismic waves are waves of energy that travel through the Earth’s crust and are caused by sudden disturbances, such as earthquakes. These waves can be detected by seismometers and are used to measure the magnitude and location of an earthquake. Tsunamis, on the other hand, are huge waves created by earthquakes, volcanic eruptions, and other …

Sonar is a technology used to detect and track underwater objects such as submarines, ships, fish, and whales. It uses sound waves to create a picture of the underwater environment. Sonar is also used to measure ocean depths. Sonar is an acronym for Sound Navigation and Ranging.
Ultrasonography is a medical imaging technique that uses high-frequency sound waves to create images of the inside of the body. It is used to diagnose and monitor a variety of medical conditions, including pregnancy, abdominal pain, cancer, heart and vascular disease, and musculoskeletal disorders. Ultrasonography can also be used to guide minimally-invasive procedures such as …
Echocardiography is a type of medical imaging that uses ultrasound waves to create images of the heart. It is used to diagnose heart disease and evaluate the structure and function of the heart. The images obtained from echocardiography can show the size and shape of the heart chambers, the thickness of the heart wall, the …
Non-destructive Testing: Ultrasonic waves are used to detect cracks, flaws and other defects in objects without damaging them. Medical Imaging: Ultrasound is used in medical imaging, such as echocardiography, to view the inside of the body. Cleaning: Ultrasonic waves are used to clean jewelry and other delicate items. Communication: Ultrasonic waves can be used to …

Infra sound is sound that is lower than the human hearing range (below 20Hz). It is usually felt as a vibration, due to its low frequency. It can be produced by natural events such as volcanic eruptions, earthquakes, and avalanches, as well as man-made sources such as industrial machinery and explosions. Ultra sound is sound …

Increase the absorption of sound in the room: Adding acoustic paneling to the walls, ceilings, and floors can help reduce the reverberation and potential echoes. Install sound-absorbing materials: Carpeting, draperies, and other soft materials can help absorb sound waves and reduce the amount of sound reflected. Use acoustic diffusers: Acoustic diffusers are designed to scatter …
The acoustics of a building refers to the sound quality within a given space and the ability of sound to travel within the space. Different materials and building elements affect the acoustics of a building. For example, hard surfaces such as concrete or tile will reflect sound, while softer materials such as carpet or acoustic …
