What else can I help you with?
When an earthquake occurs which types of wave will be detected first?
P-waves.
Which type of seismic waves cannot be detected on the side of Earth opposite an earthquake?
Surface waves, such as Love waves or Rayleigh waves, are the seismic waves that cannot be detected on the side of Earth opposite an earthquake. These waves travel along the Earth's surface and are responsible for causing most of the damage during an earthquake.
An area where no direct seismic waves from a particular earthquake can be detected?
shadow zone
What is shadow zones?
An area on Earth's surface where no direct seismic waves from a particular earthquake can be detected.
What is a sentence for seismograph?
Sentence: A Seismograph is a machine used to measure the severity of earthquakes.
Why can s waves not be detected everywhere on earth after an earthquake?
S waves, or secondary waves, are a type of seismic wave that can only travel through solids. Since the Earth's outer core is liquid, S waves cannot pass through it, which creates an area on the opposite side of the Earth from an earthquake's epicenter where these waves are not detected. This results in an S-wave shadow zone, typically located between 103 and 180 degrees from the earthquake's source, where no S waves are recorded. Thus, their inability to traverse liquid prevents them from being detected everywhere on Earth after an earthquake.
Why did the Boxing Day tsunami be felt in the Philippines but no tsunami was detected there?
The Earthquake that triggered the Tsunami was the noise that could be heard.
What is the smallest earthquake ever recorded?
the smallest earthquake recorded on the Richter scale was 0.1
What is an observed phenomenon?
An observed phenomenon is an occurrence or event that can be perceived through the senses or detected through instruments or measurements. It is something that is witnessed or documented by individuals or researchers during their observations or experiments.
When an earthquake occurs seismic waves travel outward from the?
When an earthquake occurs, seismic waves travel outward from the focus (the point where the earthquake originates) through the Earth's crust and mantle. These waves can be detected by seismometers and help scientists study the characteristics of the earthquake and the structure of the Earth's interior.
Approximately how far is an observer from and earthquake epicenter if he or she observed a p wave 8 minutes after the earthquake?
Based on the average speed of a P-wave (6 km/s), if the observer detected the P-wave 8 minutes after the earthquake, they would be approximately 2880 km away from the epicenter. This calculation assumes the P-wave travelled directly through the Earth without any barriers altering its speed.
A machine that tells you that an earthquake is coming is called?
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
