There are several types of waves in various fields named after people. Here is a list of some notable ones: 1. **S波 (S-wave)**: Named after the German physicist William Thomson, 1st Baron Kelvin (Kelvin waves) 2. **P波 (P-wave)**: Named after the German physicist August Kundt 3. **Rayleigh wave**: Named after Lord Rayleigh, a British scientist 4.

A seiche is a standing wave that occurs in an enclosed or partially enclosed body of water, such as a lake, bay, or harbor. It is characterized by oscillations of the water level that can last for hours or even days after the initial disturbance.

Granulometric analysis, often referred to as grain size analysis or particle size analysis, is a technique used to determine the size distribution of particles within a sample. This method is commonly applied in various fields such as geology, soil science, sedimentology, and material science to characterize materials based on the size of their individual particles. The analysis typically involves the following steps: 1. **Sampling:** A representative sample of the material is collected for analysis.

Loss on ignition (LOI) is a quantitative measure commonly used in various fields such as geology, material science, chemistry, and environmental science to determine the amount of combustible material in a sample. It is typically expressed as a percentage of the initial weight of the sample. The process involves the following steps: 1. **Sample Preparation**: A solid sample, such as soil, sediment, or a rock, is collected and prepared for analysis.

The Sand Equivalent Test is a laboratory test used to determine the relative amount of fine dust or clay-like materials in soil or aggregate samples. It is particularly useful in assessing the quality of materials used in construction, especially in concrete and asphalt applications. ### Purpose: The main purpose of the Sand Equivalent Test is to measure the contamination of fine aggregates (such as sand) with deleterious materials like clay, silt, or dust.

Paul Moody (1794–1846) was an American inventor and engineer known primarily for his contributions to the development of textile manufacturing equipment. He played a significant role in the advancement of the textile industry during the early 19th century. One of his notable inventions was the "power loom," which revolutionized the way textiles were produced and helped to mechanize the weaving process.

"Thomas Highs" is not a widely recognized term or name in common contexts. It may refer to a specific location, a person, or perhaps even a fictional character depending on the context. It could also be a typo or misspelling of something else.

Seismic history refers to the record of past seismic events, particularly earthquakes, in a specific region or globally. This history is significant for understanding seismic hazards, assessing risks, and establishing building codes and safety measures. Seismic history encompasses several aspects: 1. **Historical Earthquake Records**: These include documented accounts of significant earthquakes, their magnitudes, epicenters, and impacts on populations and infrastructure. Historical records can extend back centuries or millennia and may include archaeological evidence or folklore.

A coal mine bump, also known as a "bump" or "coal bump," refers to a sudden collapse or movement of rock strata in a coal mine. This phenomenon occurs when there is a rapid release of built-up stress in the rock, often caused by the extraction of coal. The term is commonly used in the context of underground mining operations.

Epicentral distance is the distance measured from the epicenter of an earthquake to a specific point, usually a seismic station or observation point on the Earth's surface. The epicenter is the point on the Earth's surface directly above the focus (or hypocenter), where the earthquake originates. Epicentral distance is typically expressed in kilometers or miles.

A P wave, or primary wave, is a type of seismic wave that is the first to be recorded by seismographs following an earthquake. Here are some key characteristics of P waves: 1. **Nature**: P waves are longitudinal waves, meaning that they cause particles in the material through which they travel to oscillate back and forth in the same direction as the wave is moving. This results in areas of compression and rarefaction.

A sand boil, also known as a sand boil-out or sand vent, is a geological phenomenon that occurs during a flooding event or when groundwater pressure is high. It happens when water forces its way to the surface through a layer of sand or other loose sediment. Typically, this occurs when water saturates the soil, causing increased pore pressure that cannot be supported by the overlying material.

Seismic magnitude scales are systems used to quantify the size or energy released by earthquakes. These scales provide a numerical value that helps describe the intensity of seismic events and allows for comparisons between them. Several different magnitude scales are used, each with its specific characteristics: 1. **Richter Scale**: Developed in 1935 by Charles F. Richter, this scale measures the amplitude of seismic waves recorded by seismographs.

Strong ground motion refers to the intense shaking of the ground caused by seismic waves generated during an earthquake. This phenomenon is crucial in the study of earthquakes and their effects on structures, infrastructure, and the environment. Strong ground motion can be characterized by high accelerations, velocities, and displacements of the ground over a short duration, typically lasting from a few seconds to several minutes, depending on the earthquake's magnitude, depth, and distance from the epicenter.

The Clarke number is a measure used in the field of group theory, particularly in the study of simple groups. It is named after mathematician Marshall Hall Jr. and is defined as the minimum number of members needed in a sequence of certain types of groups to generate a simple group. In practical terms, the Clarke number signifies the complexity of a simple group regarding how it can be constructed from smaller groups.

In geology, "hotspots" refer to specific locations on the Earth's surface that are characterized by volcanic activity resulting from underlying mantle plumes. These plumes are columns of hot, solid mantle material that rise from deep within the Earth, potentially originating from the core-mantle boundary. Hotspots can create volcanic islands and chains as tectonic plates move over them. As a tectonic plate shifts, the hotspot remains fixed, allowing a series of volcanoes to form in a line.

Core–mantle differentiation refers to the geological process by which a planet, such as Earth, separates into distinct layers based on differences in composition, density, and physical properties. This process is primarily observed during the early stages of a planet's formation, shortly after it has formed from the accretion of dust and gas in the protoplanetary disk. In the case of Earth, differentiation involves the separation of the planet into a dense metallic core and a lighter silicate mantle.

The lower mantle is a significant layer of the Earth's interior, located beneath the upper mantle and above the outer core. It extends from about 660 kilometers (410 miles) to approximately 2,900 kilometers (1,800 miles) beneath the Earth's surface. This region is characterized by high pressures and temperatures, which increase with depth.

"Dave Price" could refer to a few different individuals or topics depending on the context. One notable figure is Dave Price, an American television personality and meteorologist known for his work with various news stations, including CBS New York. He has also made appearances on reality television shows.

Frostbite is a medical condition that occurs when skin and other tissues freeze due to exposure to extremely cold temperatures. It typically affects fingers, toes, ears, and the nose, which are extremities that are often exposed to cold air. The risk of frostbite increases with wind chill, wet conditions, and prolonged exposure to low temperatures.
