1921 Massawa Earthquake
The 1921 Massawa earthquake took place off the coast of Massawa, Eritrea, on August 14 with a moment magnitude of 6.1 and a Mercalli intensity of VIII (''Severe''). The first aftershock after the initial earthquake was of similar magnitude. Significant damage was caused to the harbour at Massawa with a number of deaths reported. Aftershocks were felt as far away as Asmara and Dekemhare.

Eritrea
Eritrea ( ; ti, ኤርትራ, Ertra, ; ar, إرتريا, ʾIritriyā), officially the State of Eritrea, is a country in the Horn of Africa region of Eastern Africa, with its capital and largest city at Asmara. It is bordered by Ethiopia in the south, Sudan in the west, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately , and includes the Dahlak Archipelago and several of the Hanish Islands. Human remains found in Eritrea have been dated to 1 million years old and anthropological research indicates that the area may contain significant records related to the evolution of humans. Contemporary Eritrea is a multi-ethnic country with nine recognised ethnic groups. Nine different languages are spoken by the nine recognised ethnic groups, the most widely spoken language being Tigrinya, the others being Tigre, Saho, Kunama, Nara, Afar, Beja, Bilen and Ar ...

Massawa
Massawa ( ; ti, ምጽዋዕ, məṣṣəwaʿ; gez, ምጽዋ; ar, مصوع; it, Massaua; pt, Maçuá) is a port city in the Northern Red Sea region of Eritrea, located on the Red Sea at the northern end of the Gulf of Zula beside the Dahlak Archipelago.Matt Phillips, Jean-Bernard Carillet, ''Lonely Planet Ethiopia and Eritrea'', (Lonely Planet: 2006), p.340. It has been a historically important port for many centuries. Massawa was the capital of the Italian Colony of Eritrea until the seat of the colonial government was moved to Asmara in 1897. Massawa has an average temperature of nearly , which is one of the highest experienced in the world, and is "one of the hottest marine coastal areas in the world." History Massawa was originally a small seaside village, lying in lands coextensive with the Kingdom of Axum—also known as Kingdom of Zula in antiquity—and overshadowed by the nearby port of Adulis about to the south. Massawa has been ruled or occupied by a successi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modified Mercalli Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "" magnitude usually reported for an earthquake). While shaking is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Deeper earthquakes also have less interaction with the surface, and their energy is spread out across a larger volume. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Intensity scales empirically categorize the intensity of shaking based on the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asmara
Asmara ( ), or Asmera, is the capital and most populous city of Eritrea, in the country's Central Region. It sits at an elevation of , making it the sixth highest capital in the world by altitude and the second highest capital in Africa. The city is located at the tip of an escarpment that is both the northwestern edge of the Eritrean Highlands and the Great Rift Valley in neighbouring Ethiopia. In 2017, the city was declared as a UNESCO World Heritage Site for its well-preserved modernist architecture. The site of Asmera was first settled in 800 BC with a population ranging from 100 to 1,000. The city was then founded in the 12th century AD after four separate villages unified to live together peacefully after long periods of conflict. Under Italian rule the city of Asmara was made capital of Eritrea in the last years of the 19th century.

Dekemhare
Dekemhare (sometimes spelled ''Decamare'') is a town in Eritrea, lying south east of Asmara. Developed as an industrial center, it became a large scale industrial and transportation city, known for its vineyards but was partly destroyed in the Eritrean War of Independence. History The settlement of Dequ-Mehari, now perched above the town of Dekemhare, was founded in the 15th century as a small-scale agricultural community. It was previously overshadowed by the nearby settlement of Gura, which was the location of several battles (including a major one during the 19th century Ethio-Egyptian War) and previously gave its name to Dequ-Mehari's valley. Following their invasion, the Italians devoted significant resources into developing Gura and Dekemhare as an important transportation center. Gura received an air base and a major road was built connecting Dekamhare with the port Nefasit. The Italians built a number of contemporary services in the town. The town became a major base ...

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collecti ...

National Geophysical Data Center
The United States National Geophysical Data Center (NGDC) provided scientific stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. In 2015, NGDC was merged with the National Climatic Data Center (NCDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI). Location and controlling bodies The NGDC, was located in Boulder, Colorado as a part of the US Department of Commerce (USDOC), National Oceanic & Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS). Data holdings NGDC's data holdings contained more than 300 digital and analog databases, some of which were very large. As technology advanced, so did the search for more efficient ways of preserving these data. This data is now maintained by the NCEI. Data contributors NGDC worked closely with contri ...

Earthquakes In Eritrea
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes c ...
