Seikei Sekiya
, alternatively Sekiya Kiyokage, was a Japanese geologist, one of the first seismologists, influential in establishing the study of seismology in Japan and known for his model showing the motion of an earth-particle during an earthquake. Career Sekiya took up the study of the earthquakes in 1880. In 1886, he was appointed as the first professor of seismology at what was to be the University of Tokyo, the first such full-time university appointment in the world. In this position, he helped in the extension of the seismic survey in Japan and in the erection of seismographs throughout the country. In 1886, the number of observing stations was over 600. In 1896, at the time of his death it had risen to 968. Outside the scientific community, Sekiya is best known for the model representing the motion of the ground during an earthquake, inspired by the Tokyo earthquake of 1887. His earthquake model consists of three twisted copper wires that are mounted side by side on a lacquered wo ...

Geology
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ev ...

Academic Staff Of The University Of Tokyo
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions ...

Volcanology
Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geology, geological, geophysical and geochemistry, geochemical phenomena (volcanism). The term ''volcanology'' is derived from the Latin language, Latin word ''Vulcan (mythology), vulcan''. Vulcan was the ancient Roman mythology, Roman god of fire. A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions. Volcanologists frequently visit volcanoes, especially active ones, to observe volcanic eruptions, collect eruptive products including tephra (such as Volcanic ash, ash or pumice), Rock (geology), rock and lava samples. One major focus of enquiry is the prediction of eruptions; there is currently no accurate way to do this, but predicting or forecasting eruptions, like predicting earthquakes, could save many lives.

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca.

English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers.

1888 Eruption Of Mount Bandai
The 1888 eruption of Mount Bandai was a major volcanic eruption which occurred during the Meiji period of the Empire of Japan. The eruption occurred on July 15, 1888, pyroclastic flows buried villages on the northern foot of the mountain, and devastated the eastern part of Bandai region, Iwashiro Province (now part of Fukushima Prefecture) north of Tokyo. At least 477 people were killed, and hundreds more were injured and rendered homeless.Smith, Encyclopedia of Geology, pp 461 Mount Bandai is a stratovolcano. Its most recent previous eruption had occurred in 806. Mount Bandai had a conical profile, and had been compared in literature with Mount Fuji. The Bandai volcano consisted of four peaks: O-bandai (1,819 meters), Kushigamine (1,636 meters), Akahaniyama (1,427 meters), and Ko-bandai which was slightly lower than that of O-bandai. Small earthquakes were reported on 8, 9 and 10 July. Moderate earthquakes occurred on 13 and 14 July. However, as earthquakes are commonplace al ...

Ground Motion
Ground motion is the movement of the Earth’s surface from earthquakes or explosions. Ground motion is produced by seismic waves that are generated by sudden slip on a fault or sudden pressure at the explosive source and travel through the Earth and along its surface. This can be due to natural events, such as earthquakes and volcanic eruptions, or human activities, such as the detonation of nuclear weapons. There are two main types of seismic waves: body waves and surface waves. Body waves travel through the interior of the Earth, while surface waves travel along the Earth's surface. Ground motion is typically caused by surface waves, which are the most destructive type of seismic waves. Ground motion is measured using a seismometer A seismometer is an instrument that responds to ground displacement and shaking such as caused by quakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The ou ...

Seismology
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies. It also includes studies of the environmental effects of earthquakes such as tsunamis; other seismic sources such as volcanoes, plate tectonics, glaciers, rivers, oceanic microseisms, and the atmosphere; and artificial processes such as explosions. Paleoseismology is a related field that uses geology to infer information regarding past earthquakes. A recording of Earth's motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist who works in basic or applied seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletu ...

Earthquake Engineering Research Institute
The Earthquake Engineering Research Institute (EERI) is a leading technical society in dissemination of earthquake risk and earthquake engineering research both in the U.S. and globally. EERI members include researchers, geologists, geotechnical engineers, educators, government officials, and building code regulators. History The EERI was formed in 1948 as an advising committee of the United States Coast and Geodetic Survey. It quickly became its own independent, nonprofit organization, with the purpose of studying why buildings fail under earthquake disasters, and what methods can prevent these failures. At first they conducted their research in laboratories of different University or Government groups. As the EERI grew, they began to more often send research funds to the Universities, and have the university conduct the research. EERI focused more on identifying and investigating areas in need of research, and policymaking based on the university's lab results. In 1952 the ...
