2007 Nevelsk Earthquake
The 2007 Nevelsk earthquake affected the island of Sakhalin in Russia and generated a tsunami along its coast. The 6.2 shock occurred at a depth of , and had an epicenter located off the coast of Kholmsk at 13:37 local time ( MAGT) on 2 August. It was caused by reverse faulting on a north–south striking and west dipping fault. More than 1,800 aftershocks were recorded by the end of the year. At least four people died and at least 12 were injured. It rendered 250 buildings uninhabitable due to their severety of damage and left 8,000 people homeless. Three tsunami waves struck the island's coast with a maximum height of , and small waves were observed in Hokkaido, Japan; no damage occurred. Tectonic setting Sakhalin is situated at the boundary of the Eurasian and North American plates where oblique convergence occur. In the southern part of the island, the estimated convergence rate is per year. Three major fault systems run through the island; the Rebun– Moneron, Wester ...

MAGT
Magadan Time (MAGT) (, ''magadanskoye vremya'') is a time zone in Russia, named after Magadan, the administrative center of Magadan Oblast. It is 11 hours ahead of UTC (UTC+11) and 8 hours ahead of Moscow Time (MSK+8). Between 26 October 2014 and 24 April 2016, Magadan Oblast was in UTC+10 (MSK+7), that is Vladivostok Time. During this time, the UTC+11:00 (MSK+8) time zone was named Srednekolymsk Time, and was used by only 27,000 residents in the eastern districts of the Sakha Republic and northern Kuril Islands. The time in Magadan has been as follows: (IANA) Areas on Magadan Time * * |
Local Magnitude Scale
The Richter scale (), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or .. Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses common logarithms simply to make the measurements manage ...

Wakkanai is the capital of Sōya Subprefecture. Situated approximately 1,100 km north of Tokyo and 270 km north of Sapporo, it is the northernmost municipality under Japanese administration following the loss of Karafuto Prefecture, Karafuto (present-day Sakhalin) and the Kuril Islands, with Benten-jima (Wakkanai), Benten-jima being the northernmost point under Japanese control. Wakkanai started as the Matsumae Domain's trading post with the Ainu people in 1685. Edo period, Edo-period explorer Mamiya Rinzō set sail for his famous Karafuto expedition from the settlement. After Japan regained Karafuto following its victory in the Russo-Japanese War in 1905, Wakkanai rose to prominence as a gateway to this reclaimed territory.

Tectonic Uplift
Tectonic uplift is the orogeny, geologic uplift of Earth#Surface, Earth's surface that is attributed to plate tectonics. While Isostasy, isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of Thrust tectonics, crustal thickening (such as Mountain formation, mountain building events), changes in the density distribution of the crust and underlying Mantle (geology), mantle, and flexural support due to the bending of rigid lithosphere. Tectonic uplift results in denudation (processes that wear away the earth's surface) by raising buried rocks closer to the surface. This process can redistribute large loads from an elevated region to a topographically lower area as well – thus promoting an isostatic response in the region of denudation (which can cause local bedrock uplift). The timing, magnitude, and rate of denudation can be estimated by geologists using pressure-temperature studies. Crustal thickening C ...

Ebb Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tide Gauge
A tide gauge is a device for measuring the change in sea level relative to a vertical datum. It is also known as a mareograph, marigraph, and sea-level recorder. When applied to freshwater continental water body, water bodies, the instrument may also be called a limnimeter. Operation Sensors continuously record the height of the water level with respect to a height reference surface close to the geoid. Water enters the device by the bottom pipe (far end of the tube, see picture), and electronic sensors measure its height and send the data to a tiny computer. Historical data are available for about 1,450 stations worldwide, of which about 950 have provided updates to the global data center since January 2010. At some places records cover centuries, for example in Amsterdam where data dating back to 1700 is available. When it comes to estimating the greater ocean picture, new modern tide gauges can often be improved upon by using satellite data. Tide gauges are used to measure t ...

Boarding School
A boarding school is a school where pupils live within premises while being given formal instruction. The word "boarding" is used in the sense of "room and board", i.e. lodging and meals. They have existed for many centuries, and now extend across many countries. Their functioning, codes of conduct, and ethos vary greatly. Children in boarding schools study and live during the school year with their fellow students and possibly teachers or administrators. Some boarding schools also have day students who attend the institution during the day and return home in the evenings. Boarding school pupils are typically referred to as "boarders". Children may be sent for one to twelve years or more in boarding school, until the age of eighteen. There are several types of boarders depending on the intervals at which they visit their family. Full-term boarders visit their homes at the end of an academic year, semester boarders visit their homes at the end of an academic term, weekly boarders ...

Yuzhno-Sakhalinsk
Yuzhno-Sakhalinsk (, , ) is a city and the administrative center of Sakhalin Oblast, Russia. It is located on Sakhalin Island in the Russian Far East, north of Japan. Gas and oil extraction as well as processing are amongst the main industries on the island. It was called Vladimirovka () from 1882 to 1905, then during its period of Imperial Japanese control from 1905 to 1946. As of the 2010 Census, its population was 181,728. History Yuzhno-Sakhalinsk began as a small Russian settlement called Vladimirovka, founded by convicts in 1882. The Treaty of Portsmouth in 1905, which brought an end to the Russo-Japanese War of 1904–1905, awarded the southern half of the Sakhalin Island to Japan. Vladimirovka was renamed Toyohara (meaning "bountiful plain"), and was the prefect capital of the Japanese Karafuto Prefecture. During the Soviet–Japanese War within World War II, the city was recaptured by Soviet troops. Ownership of the city was transferred to the Soviet Union and it w ...
