2017 Ischia Earthquake
The 2017 Ischia earthquake occurred in the island of Ischia, Campania, in southern Italy. The main shock occurred at 20:57 CEST (18:57 UTC) on 21 August 2017, and was rated 3.9 or 4.2 on the moment magnitude scale. Despite the moderate magnitude, several buildings and a church collapsed. One woman died in Casamicciola Terme after being hit by rubble that fell from a church. Another woman died when her house collapsed. Damage and debates The collapse of several buildings and the death of two women created much controversy and debate in Italy, because many geologists stated that with a moderate magnitude quake, modern buildings should not collapse. Moreover, Ischia is a zone with a high number of irregular buildings, and many critics considered the poor construction materials as the main cause for the death of the two women and for the damage. The sharp increase of the population between 1950s and 1980s and the growing inflow of tourists increased the anthropic pressure on th ...

Ischia
Ischia ( , , ) is a volcanic island in the Tyrrhenian Sea. It lies at the northern end of the Gulf of Naples, about from Naples. It is the largest of the Phlegrean Islands. Roughly trapezoidal in shape, it measures approximately east to west and north to south and has about of coastline and a surface area of . It is almost entirely mountainous; the highest peak is Mount Epomeo, at . The island is very densely populated, with 62,000 residents (more than 1,300 inhabitants per square km). Ischia is also well known for its thermal water and thermal gardens used since ancient times. Its volcanic nature makes Ischia one of the largest spas in Europe. Ischia's thermal waters are alkaline. Already the first Euboic settlers (8th century BC), as evidenced by the numerous archaeological finds found in the site of Pithecusa and preserved in thArchaeological Museum of Villa Arbustoin Lacco Ameno, appreciated and used the waters of the island's thermal springs. The Greeks, in fact, used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campania
Campania (, also , , , ) is an administrative Regions of Italy, region of Italy; most of it is in the south-western portion of the Italian peninsula (with the Tyrrhenian Sea to its west), but it also includes the small Phlegraean Islands and the island of Capri. The capital of the Campania region is Naples. As of 2018, the region had a population of around 5,820,000 people, making it Italy's third most populous region, and, with an area of , its most densely populated region. Based on its Gross domestic product, GDP, Campania is also the most economically productive region in southern Italy List of Italian regions by GDP, and the 7th most productive in the whole country. Naples' urban area, which is in Campania, is the List of urban areas in the European Union, eighth most populous in the European Union.

Central European Time
Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time (MET, German: MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST). The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones. As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. In Africa, UTC+01:00 is called West Africa Time (WAT), where it is used by several countries, year round. Algeria, Morocco, and Tunisia also refer to it as ''Central European ...

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casamicciola Terme
Casamicciola Terme is a ''comune'' (municipality) in the Metropolitan City of Naples in the Italian region Campania, located in the northern part of the Ischia Island. Geography Casamicciola Terme borders the following municipalities: Barano d'Ischia, Forio, Ischia, Lacco Ameno, Serrara Fontana. History In 1883, an earthquake struck the northern part of Ischia. Despite the moderate magnitude of 4.2–5.5, many buildings in the across the island were totally destroyed. The city was heavily damaged—many homes and businesses were demolished. At least 2,313 people were killed—1,784 people died in the city alone. On August 21, 2017 was hit by a 4.3 magnitude earthquake, killing two people wounding 42 more, and causing damage to some houses. On November 26, 2022 strong rainfall led to a landslide killing of 12 lives and left over 200 people homeless. The severe landslide caused the destruction or damage of numerous buildings in Casamicciola.https://www.nytimes.com/2022/12/03/w ...

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...

List Of Earthquakes In Italy
This is a list of earthquakes in Italy that had epicentres in Italy, or significantly affected the country. The highest seismicity hazard in Italy was concentrated in the central-southern part of the peninsula, along the Apennine Mountains, Apennine ridge, in Calabria and Sicily and in some northern areas, like Friuli-Venezia Giulia, Friuli, part of Veneto and western Liguria. Geology Italy lies on the southern extent of the Eurasian Plate, which is surrounded by the Aegean Sea Plate, the Adriatic Plate, and the Anatolian Plate. The Apennine Mountains contain numerous faults that run along the entire Italian peninsula and form the majority of the destructive boundary between the Eurasian and the Adriatic plates, thus causing Italy to have high amounts of tectonic activity. In addition, Sicily and Calabria are located near the boundary where the African plate is subducting below the Eurasian plate, which was responsible for forming the stratovolcano known as Mount Etna.

1883 Casamicciola Earthquake
The 1883 Casamicciola earthquake, also known as the Ischia earthquake occurred on 28 July at 20:25 local time (Central European Time) on the island of Ischia in the Gulf of Naples in Italy. Although the earthquake had an estimated moment magnitude () of 4.2 to 5.5, considered moderate in size, it caused intense ground shaking that was assigned XI (''Extreme'') on the Modified Mercalli intensity scale. Of the 26,000 inhabitants in the town of Casamicciola, at least 2,313–3,100 people lost their lives. The city also suffered great property losses, with 80% of all homes destroyed. This earthquake was exceptionally destructive for its magnitude mainly due to its shallow focal depth. Tectonic setting Ischia island is situated in the circular caldera which forms the Phlegraean Fields of volcanoes. The volcanic field itself is part of the greater Campanian volcanic arc. The island's highest point, Monte Epomeo, is not a volcanic cone. Instead, it is a geological horst, a block of v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
