Pamatan is the name of a lost city on Lombok Island in Indonesia and the capital of the principal kingdom on Lombok. The city was destroyed by the 1257 Samalas eruption; while the king and at least part of his family survived, many inhabitants were killed. The location of the city is unclear but probably was on the eastern coast of Lombok.
The history of Pamatan and the 1257 eruption of Samalas is recorded in the Babad Lombok , a compilation of historical writings and possibly oral tradition written in the Old Javanese language on palm leaves. [1] [2] According to the Babad Lombok, Pamatan was founded at the foot of Samalas-Rinjani after a previous (probably legendary) city had been abandoned. It is likely that the city was located on the sea, most likely on the eastern side of Lombok; possible locations are at Aikmel and Sembalun. The Babad Lombok says that the city had a population of about 10,000 people and featured city walls, town halls, houses, and boulevards. Its inhabitants were wealthy and active in agriculture, fishing, and trade. The city was the capital of a kingdom; at the time, Lombok had multiple kingdoms, of which Pamatan was the most important. [1]
When Samalas erupted in 1257, the city was destroyed; pyroclastic flows swept the houses away and partially into the sea. The Babad Lombok states that there were numerous casualties, but other inhabitants, including part of the royal family, escaped and moved to villages and towns that had survived the eruption. People took refuge on hills and mountains which were spared by pyroclastic flows. Others escaped by boats over sea. [1] Reportedly, the king and his family survived the eruption, but the city disappeared from history and its location was lost; [3] if it were to be rediscovered, it may become a "Pompeii of the East". [2]
According to the Babad Lombok, after the eruption new settlements were built by survivors. There is, as of 2022 [update] , little archeological evidence with which to corroborate its narrative. [1] It is likely that Lombok was devastated by the eruption, facilitating its conquest from Bali in 1284. [2] If rediscovered, Pamatan may offer clues on how societies respond to volcanic catastrophes. [2] Contemporary historical records give indications but they cannot be verified archeologically. [1]
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" to the southwest, about 70 kilometres across and a total area of about 4,607.38 square kilometres including smaller offshore islands. The provincial capital and largest city on the island is Mataram.
Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than 4,300 metres high, making it one of the tallest peaks in the Indonesian archipelago.
Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder.
Mount Agung is an active volcano in Karangasem Regency, Bali, Indonesia. It is located southeast of Mount Batur volcano, also in Bali. It is the highest point on Bali, and dominates the surrounding area, influencing the climate, especially rainfall patterns. From a distance, the mountain appears to be perfectly conical. From the peak of the mountain, it is possible to see the peak of Mount Rinjani on the nearby island of Lombok, to the east, although both mountains are frequently covered in clouds. Agung is a stratovolcano, with a large and deep crater. Its most recent eruptions occurred from 2017–2019.
The Sunda Arc is a volcanic arc that produced the volcanoes that form the topographic spine of the islands of Sumatra, Nusa Tenggara, Java, the Sunda Strait, and the Lesser Sunda Islands. The Sunda Arc begins at Sumatra and ends at Flores, and is adjacent to the Banda Arc. The Sunda Arc is formed via the subduction of the Indo-Australian Plate beneath the Sunda and Burma plates at a velocity of 63–70 mm/year.
Mount Rinjani is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara. It rises to 3,726 metres (12,224 ft), making it the second highest volcano in Indonesia. It is also the highest point in the Indonesian province of West Nusa Tenggara. Adjacent to the volcano is a 6-by-8.5-kilometre caldera, which is filled partially by the crater lake known as Segara Anak or Anak Laut, due to the color of its water, as blue as the sea (laut). This lake is approximately 2,000 metres (6,600 ft) above sea level and estimated to be about 200 metres (660 ft) deep; the caldera also contains hot springs. The lake and mountain are sacred to the Sasak people and Hindus, and are the site of religious rituals. UNESCO made Mount Rinjani Caldera a part of the Global Geoparks Network in April 2018. Its catastrophic eruption in 1257 was the largest volcanic eruption in the last 2000 years.
Segara Anak is a crater lake in the caldera that formed during the explosive volcanic eruption of Mount Samalas in 1257. The caldera is next to Mount Rinjani on Lombok Island in Indonesia. "Segara Anak" means "child of the sea" and refers to the blue lake's resemblance to the sea. The volcanic cone Gunung Barujari is at the eastern end of the lake and is responsible for its crescent shape. The lake temperature is 20–22 °C (68–72 °F), which is 5–7 °C (9.0–12.6 °F) higher than normal for a lake at its altitude. Hot magma below the lake is responsible for this anomaly. Gas bubbles escape from the lake floor, helping the lake to have a pH of 7–8.
North Lombok Regency is a regency of the Indonesian Province of West Nusa Tenggara. It is located in the northwest of the island of Lombok and includes the offshore Gili Islands. The capital is Tanjung situated on the northwest coast of the island. The regency covers an area of 809.53 km2 and had a population of 200,072 at the 2010 Census and 247,400 at the 2020 Census; the official estimate as at mid 2023 was 265,500.
This timeline of volcanism on Earth includes a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic explosivity index (VEI) or equivalent sulfur dioxide emission during the Quaternary period. Other volcanic eruptions are also listed.
The 946 eruption of Paektu Mountain, a stratovolcano on the border of North Korea and China also known as Changbaishan, occurred in late 946 CE. This event is known as the Millennium Eruption or Tianchi eruption. It is one of the most powerful volcanic eruptions in recorded history; classified at least a VEI 6.
Dispersal index is a parameter in volcanology. The dispersal index was defined by George P. L. Walker in 1973 as the surface area covered by an ash or tephra fall, where the thickness is equal or more than 1/100 of the thickness of the fall at the vent. An eruption with a low dispersal index leaves most of its products close to the vent, forming a cone; an eruption with a high dispersal index forms thinner sheet-like deposits which extends to larger distances from the vent. A dispersal index of 500 square kilometres (190 sq mi) or more of coarse pumice is one proposed definition of a Plinian eruption. Likewise, a dispersal index of 50,000 square kilometres (19,000 sq mi) has been proposed as a cutoff for an ultraplinian eruption. The definition of 1/100 of the near-vent thickness was partially dictated by the fact that most tephra deposits are not well preserved at larger distances.
In 1257, a catastrophic eruption occurred at Samalas, a volcano on the Indonesian island of Lombok. The event had a probable Volcanic Explosivity Index of 7, making it one of the largest volcanic eruptions during the Holocene epoch. It left behind a large caldera that contains Lake Segara Anak. Later volcanic activity created more volcanic centres in the caldera, including the Barujari cone, which remains active.
Littoral cones are a form of volcanic cone. They form from the interaction between lava flows and water. Steam explosions fragment the lava and the fragments can pile up and form a cone. Such cones usually form on ʻaʻā lava flows, and typically are formed only by large lava flows. They have been found on Hawaii and elsewhere.
The Tierra Blanca Joven eruption of Lake Ilopango was the largest volcanic eruption in El Salvador during historic times, and one of the largest volcanic events on Earth in the past 7,000 years, registering at 6 on the Volcanic explosivity index (VEI), and dating back to the mid 5th century A.D. The eruption produced between 37–82 km3 (8.9–19.7 cu mi) of ejecta. The date of the eruption has been constrained within 429–433 CE by identifying its signature volcanic ash in precision-dated ice cores sampled from Greenland, thus eliminating it as the cause of extreme weather events of 535–536.
The 1452/1453 mystery eruption is an unidentified volcanic event that triggered the first large sulfate spike in the 1450s, succeeded by another spike in 1458 caused by another mysterious eruption. The eruption caused a severe volcanic winter leading to one of strongest cooling events in the Northern Hemisphere. This date also coincides with a substantial intensification of the Little Ice Age.
Barujari cone is an active volcano on the island of Lombok in Indonesia. A "baby volcano", it is inside the Mount Rinjani volcano.
Kie Matubu is a volcano on Tidore Island, Indonesia. While no eruptions have been recorded since the island was first inhabited during the 16th century, two eruption deposits were dated to around 2,500 and 740 years BP.
