Thomas A. Jaggar Museum
The Hawaiian Volcano Observatory (HVO) is an agency of the U.S. Geological Survey (USGS) and one of five volcano observatory, volcano observatories operating under the USGS Volcano Hazards Program. Based in Hilo, Hawaii, the observatory monitors six Hawaiian volcanoes: Kīlauea, Mauna Loa, Kamaʻehuakanaloa Seamount, Kamaʻehuakanaloa (formerly Lōʻihi), Hualalai, Hualālai, Mauna Kea, and Haleakalā, of which, Kīlauea and Mauna Loa are the most active. The observatory has a worldwide reputation as a leader in the study of active volcanism. Due to the relatively non-explosive nature of Kīlauea's volcanic eruptions for many years, scientists have generally been able to study ongoing eruptions in proximity without being in extreme danger. Prior to May 2018, the observatory's offices were located at Uwekahuna Bluff, the highest point on the rim of Kīlauea Caldera. The Halemaʻumaʻu#April to July 2018: Drainage of lava lake and the collapse of the summit caldera, summit collapse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hilo, Hawaii
Hilo () is a census-designated place (CDP) and the largest settlement in Hawaii County, Hawaii, United States, which encompasses the Island of Hawaii. The population was 44,186 according to the 2020 census. It is the fourth-largest settlement in the state of Hawaii and largest settlement in the state outside of Oahu. Hilo is the county seat of the County of Hawaii and is in the District of South Hilo. The city overlooks Hilo Bay and has views of two shield volcanoes, Mauna Loa, an active volcano, and Mauna Kea, a dormant volcano. Mauna Kea is the site of some of the world's most important ground-based astronomical observatories. The Hilo bay-front has been destroyed by tsunamis twice.

Scientist Collecting Pahoehoe, Kilauea
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusakichi Omori
was a pioneer Japanese seismologist, second chairman of seismology at the Imperial University of Tokyo and president of the Japanese Imperial Earthquake Investigation Committee. Omori is also known for his observation describing the aftershock rate of earthquakes, now known as Omori's law. Education Omori studied physics with the initial British foreign advisors serving as professors at the Imperial University of Tokyo, especially John Milne until he left Japan in 1895, as well as Japanese colleagues including Seikei Sekiya who in 1880 became the first professor of seismology at Tokyo Imperial University. Early career Sekiya and Omori published the first clear record of a destructive earthquake, obtained by their measuring devices at the university. In 1886 Sekiya was made chair of seismology and secretary to the Imperial Earthquake Investigation Committee and by the time of his death a decade later, Japan had nearly 1000 seismological recording stations to study seism ...

Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal and hu ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundred ...

Volcano House
Volcano House is the name of a series of historic hotels built at the edge of Kīlauea, within the grounds of Hawai'i Volcanoes National Park on the Island of Hawai'i. The original 1877 building is listed on the National Register of Historic Places and now houses the Volcano Art Center. The hotel in use today was built in 1941 and expanded in 1961. Between May 2018 and October 2018, the hotel and the Kīlauea summit area of the national park were closed to the public due to volcanic explosions and earthquakes. Early visitors In ancient Hawaii the volcano was the place to make offerings to the fire goddess Pele. Archeological evidence shows activity for hundreds of years, including gathering of volcanic glass to use as cutting tools. Only a few rare eruptions such as the one in 1790 are explosive, and the northeast rim provides a relatively safe vantage point. The prevailing northeast trade winds and higher elevation cause poisonous gasses and lava to flow in the other directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Lycurgus
George Lycurgus ( grc-gre, Γεώργιος Λυκούργος) (1858–1960) was a Greek American businessman who played an influential role in the early tourist industry of Hawaii. After Queen Lili`uokalani was overthrown in a coup by the Committee Of Safety, he ran afoul of the government of the Republic of Hawaii and was accused of treason. Later he was instrumental in the development of the Hawaiian Volcano Observatory and Hawaiʻi Volcanoes National Park. Early life He was born in 1858 in Vassaras (near Sparta, Greece). After his release from the Greek Army, his father decided to leave the family farm to an older brother and agreed to send George to America to join his eldest brother John, in California. In 1877 he traveled in steerage class to New York City, and worked his way across the country. A relative convinced him to join a wholesale fruit business trading between Hawaii and California in 1881. In San Francisco he shipped California produce and wine to his cousin in ...
