Earthquake waves travel faster in rocks. In rocks near the Earth's surface the waves can move at 6 or 7 kilometers per second. In water, sound can travel about 1.5 kilometers per second, and a tsunami wave can travel at up to 1000 km per hour- fast, but not nearly as fast as in the rocks.
That's why seismometers can give warnings of a possible tsunami. The earthquake waves arrive at the seismometers far in advance of any possible tsunami. But earthquakes in the seabed don't always cause tsunamis.
Some earthquake waves won't travel through water at all. The two first waves on any seismometer's trace of an earthquake are called P and S, for "primus" and "secondus" or some wretched thing- "primary" and "secondary" are good enough. But it would also be adequate to call them "pressure" and "shear," or "push" and "shake," since that's what they do. The P wave is a compression in the direction the wave is moving, like a sound wave. It will go through water or other liquids. The S-wave is a shear, a side-to-side shaking. Liquids just slip aside and absorb that kind of motion, they won't transmit it.
What else can I help you with?
Noun for volcanic?
A volcano is a vent (opening) in the earths crust through which molten materials erupts suddenly.
What is the tube that lava travels through?
It travels through a "Pipe" and explodes out the "Vent", or possibly the "Side Vent", and another world for the hole at the top is the Crater.
When do volcanic earthquakes occur?
An earthquake can be caused in two different ways, there is a volcanic earthquake and a tectonic earthquake. Tectonics earthquakes are much more common than volcanic earthquakes. Volcanic earthquakes are when magma, or molten rock, moves underground. This can cause earthquake directly in what is called a harmonic tremor, or indirectly by breaking and shifting rock. A tectonic earthquake is when stress built up by the movement of Earth's tectonic plates is released in the form of shaking.
What Made liquid by heat?
When a substance is heated, it absorbs energy in the form of heat, causing its molecules to gain kinetic energy and vibrate more rapidly. Eventually, the substance's molecular bonds weaken, allowing the particles to move more freely and rearrange into a liquid state. This process is called melting.
What called the path that magma travels along?
The path that magma travels along beneath Earth's surface is called a magma chamber or a magma conduit. It is a reservoir of molten rock that can lead to volcanic eruptions when pressure builds up and the magma is forced to the surface.
What is a magmatic?
A magmatic earthquake is an earthquake triggered by the movement of magma, underground molten rock.
Asthenosphere?
contains hot molten rocks or magma
Is an earthquake going to happen today?
The majority of the Earth is molten (liquid). The Earth never truly stops moving.
Can volcanoes form because of an earthquake?
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
What is the fastest growing crystal?
the fastest growing crystal depends on the temperature and nature of the crystal
What is the phenomenon that occurs when molten lava flows through a natural tunnel-like structure underground, known as a lava tube, and what travels through it?
The phenomenon is called lava tube formation, where molten lava flows through a natural tunnel-like structure underground. Lava travels through these tubes, allowing it to move further away from the volcanic vent.

What is the largest part of earth's interior that is made of rock but is flexible?
The asthenosphere is the largest part of Earth's interior made of rock that is flexible. It is located beneath the lithosphere and consists of partially molten rock that allows for the movement of tectonic plates.
What are the prevention techniques for earthquake?
The prevention technique for earthquake can be to bore pipe deep into the gas producing molten rock layers at several places in the earthquake prone areas, maybe several kilometers down, like it is done to harness oil from about 5 kilometers deep. The gas can be collected for some use round the year and it would prevent excess pressure building up and causing earthquake.
