19 August 2018 Lombok Earthquake
On 19 August 2018 a major earthquake struck with high intensity on the northeast corner of Lombok (Sambelia and Labuhan Lombok settlements) and northwest Sumbawa (Poto Tano settlement) at 22:56 local time, a few km to the east of the series of quakes that had been rocking the area for the past 3 weeks. It was measured at 6.9 (USGS), at a depth of 25.6 km. The Indonesian BMKG announced that it was a new major earthquake and it was not an aftershock. The earthquake occurred on the same overall structure, the Flores Back Arc Thrust Fault, however according to scientists it happened on a different thrust fault as there are many individual structures within the belt. There were 14 deaths and 1800 homes have been damaged, half severely, due to this event, including deaths on Sumbawa, following 2 deaths from the previous Lombok quake roughly 24 hours earlier. Heavy tiles fell from the local mosque, and 143 patients were being treated outdoors in makeshift tents for injuries on Sum ...

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular ''klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind thr ...

Map Of 2018 Lombok Earthquake
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Lombok
Lombok is an island in West Nusa Tenggara province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" (Sekotong Peninsula) to the southwest, about across and a total area of about including smaller offshore islands. The provincial capital and largest city on the island is Mataram. Orang Lombok is some what similar in size and density, and shares some cultural heritage with the neighboring island of Bali to the west. However, it is administratively part of West Nusa Tenggara, along with the larger and more sparsely populated island of Sumbawa to the east. Lombok is surrounded by a number of smaller islands locally called Gili. The island was home to some 3,168,692 Indonesians as recorded in the decennial 2010 censusBiro Pusat Statistik, Jakarta, 2011. and 3,758,631 in the 2020 Census;Badan Pusat Statis ...

Sumbawa
Sumbawa is an Indonesian island, located in the middle of the Lesser Sunda Islands chain, with Lombok to the west, Flores to the east, and Sumba further to the southeast. Along with Lombok, it forms the province of West Nusa Tenggara, but there have been plans by the Indonesian government to split the island off into a separate province. Traditionally, the island is known as the source of sappanwood, as well as honey and sandalwood. Its savanna-like climate and vast grasslands are used to breed horses and cattle, as well as to hunt deer. Sumbawa has an area (including minor offshore islands) of (three times the size of Lombok) with a population (at the 2020 Census) of 1,561,461.Badan Pusat Statistik, Jakarta, 2021. It marks the boundary between the islands to the west, which were influenced by religion and culture spreading from India, and the region to the east that was less influenced. In particular this applies to both Hinduism and Islam. Etymology Sumbawa is a Portu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flores Back Arc Thrust Fault
Flores Back Arc Thrust Fault is a major system of west-east trending thrust faults that extend eastwards from west of Lombok towards the islands of Sumbawa, Flores, and Alor, with a total length of at least 800 km. The thrust faults are south- dipping and lie within the back arc region of the Sunda-Banda Arc, which is related to the ongoing subduction of the Australian Plate beneath the Sunda and Banda Sea Plates. The thrust fault system developed as a result of the onset of continental collision as continental crust of the Australian Plate reached the Sunda Trench The Sunda Trench, earlier known as and sometimes still indicated as the Java Trench, is an oceanic trench located in the Indian Ocean near Sumatra, formed where the Australian- Capricorn plates subduct under a part of the Eurasian Plate. It is .... The eastern part of the fault system is also known as the Wetar thrust. Above the main thrust fault are a series of imbricate (overlapping) thrust faults. These imbri ...

5 August 2018 Lombok Earthquake
On 5 August 2018, a destructive and shallow earthquake measuring Mw 6.9 ( according to BMKG) struck the island of Lombok, Indonesia. It was the main shock following its foreshock, a nearby 6.4 earthquake on 29 July. It was followed by a nearby 6.9 earthquake on 19 August 2018. The epicentre was located inland, near Loloan Village in North Lombok Regency. The fault rupture spread to the north and reached the sea, creating tsunamis. Severe shaking was reported throughout the entire island, while strong shaking was reported on the neighboring islands of Bali and Sumbawa. Widespread damage was reported in Lombok and Bali. Officials stated that at least 80% of structures in North Lombok were damaged or destroyed. In the aftermath of the sequence of earthquakes in August, a total of 563 people were confirmed killed while more than 1,000 were confirmed injured. More than 417,000 people were displaced. This earthquake is the largest and the strongest earthquake to have hit Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
July 2018 Lombok Earthquake
A Mw 6.4 earthquake struck the island of Lombok on the morning of 29 July 2018 at a shallow depth of . Widespread damage was reported in the area, and authorities confirmed that 20 people were killed in the earthquake while hundreds were injured. The epicentre was located in Sembalun Subdistrict, East Lombok Regency. The earthquake was a foreshock to the larger 6.9 earthquake which struck the island a week later. Tectonic setting Lombok lies on the destructive plate boundary between the Australian Plate and the Sunda Plate. To the east of Bali the plate boundary starts to involve a collision between the leading edge of the Australian continent and the eastern part of the Sunda Arc and the western end of the Banda Arc. In response to this collision, the arc itself has begun to be pushed over the back-arc Bali Basin along a major thrust fault, the long Flores Thrust. The Lombok earthquake has been attributed to movement along the Flores Thrust. Earthquake The earthqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

August 2018 Events In Indonesia
August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. Its zodiac sign is Leo and was originally named ''Sextilis'' in Latin because it was the 6th month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Emperor Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt. Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but t ...

Earthquakes In Indonesia
__NOTOC__ This is an incomplete list of more recent recorded major earthquakes that have occurred within the boundaries of Indonesia. The determinants of the activity are indicated by the geology of the region, and the volcanic activity. Large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. Based on the records of the USGS, Indonesia has had more than 150 earthquakes with magnitude > 7 in the period 1901–2019.
