On the morning of January 5, 1699, a violent earthquake rocked the then Dutch East Indies city of Batavia on the island of Java, now known as the Indonesian capital city of Jakarta. Dutch accounts of the event described the earthquake as being "so heavy and strong" and beyond comparable to other known earthquakes. [1] This event was so large that it was felt throughout west Java, and southern Sumatra.

Tectonic setting

The Indonesian islands of Java, Sumatra and Lesser Sunda chain lie along a destructive plate boundary where the Australian plate meets the Sunda plate. The plates converge, with the Australian plate being much denser as it is oceanic lithosphere, subducting beneath the less dense Sunda plate. Subduction is responsible for the large megathrust earthquakes along the west coast of Sumatra and south coast of Java. It also plays a significant role in the volcanic activity on the islands. However, intraplate earthquakes can also occur as the Australian plate deforms when it is subducting; faults within the downgoing slab may result in intermediate-depth events that are also considerably large.

Damage and casualties

At least 28 people in Batavia were fatally wounded and 49 stone-constructed structures collapsed as a result of the earthquake. Some 21 homes and 29 barns were also obliterated. [2] Almost every home situated in the city suffered some extent of damage. The earthquake uprooted and toppled many trees, blocking waterways and choking river systems. At Mount Salak, a volcano on the island of Java, the violent tremors triggered landslides and debris masses, blocking rivers and causing floods. The combination of earth and vegetation produced a debris flow that passed through the Ci Liwung river and into Batavia, where it entered the Java Sea.

In the port settlement of Bantam, now Banten, the earthquake destroyed a storage warehouse and caused additional damages. In Lampung, Sumatra, the earthquake threw every home off its foundations. [3] More than 100 people were reported killed in Lampung. [4]

Earthquake

The characteristics of the event is not well determined but most likely a large intermediate-depth earthquake. Other researchers suggest it was a megathrust event with a magnitude of 9.0 Mw  along the Sunda megathrust. If it were an intraslab earthquake occurring within the downgoing Australian plate as it subducts beneath the Sunda plate along the Sunda megathrust, the estimated moment magnitude (Mw ) would be 7.4 to 8.0, with an epicenter near Batavia, and a focal depth of 100 km. [4] Modelling of the 1699 earthquake scenarios show that an intraslab earthquake of Mw  8.0 provided results consistent with historical documentation of the earthquake. High Mercalli intensity values at IX corresponds to the pattern of damage described by Dutch officials in Java and Sumatra. As Banten Province is situated on pyroclastic deposits and Quaternary sediments, seismic waves were likely amplified, resulting in higher degrees of shaking. [5] : §2.2.1 

Simulations of a magnitude 9.0 earthquake only produced shaking assigned at VI to VII which did not match the damage descriptions. Such intensities would only cause moderate damage. Weaker levels of shaking would occur in the mountainous regions, which were insufficient to trigger a landslide. [5] The earthquake was not accompanied by a tsunami, further disproving the megathrust theory for an earthquake of such intensity. [4]

Future hazard

In a simulation model, if an earthquake of similar size occurred in modern times, it would cause about 100,000 deaths. [5] : Chapter 4

Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (Mw) that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes.

<span class="mw-page-title-main">2006 Pangandaran earthquake and tsunami</span> Destructive tsunami earthquake south of Java Island

An earthquake occurred on July 17, 2006, at 15:19:27 local time along a subduction zone off the coast of west and central Java, a large and densely populated island in the Indonesian archipelago. The shock had a moment magnitude of 7.7 and a maximum perceived intensity of IV (Light) in Jakarta, the capital and largest city of Indonesia. There were no direct effects of the earthquake's shaking due to its low intensity, and the large loss of life from the event was due to the resulting tsunami, which inundated a 300 km (190 mi) portion of the Java coast that had been unaffected by the earlier 2004 Indian Ocean earthquake and tsunami that was off the coast of Sumatra. The July 2006 earthquake was also centered in the Indian Ocean, 180 kilometers (110 mi) from the coast of Java, and had a duration of more than three minutes.

The 1833 Sumatra earthquake occurred on November 25 at about 22:00 local time, with an estimated magnitude in the range of 8.8–9.2 Mw . It caused a large tsunami that flooded the southwestern coast of the island. There are no reliable records of the loss of life, with the casualties being described only as 'numerous'. The magnitude of this event has been estimated using records of uplift taken from coral microatolls.

<span class="mw-page-title-main">Sunda megathrust</span> Geological feature

The Sunda megathrust is a fault that extends approximately 5,500 km (3300 mi) from Myanmar (Burma) in the north, running along the southwestern side of Sumatra, to the south of Java and Bali before terminating near Australia. It is a megathrust, located at a convergent plate boundary where it forms the interface between the overriding Eurasian Plate and the subducting Indo-Australian Plate. It is one of the most seismogenic structures on Earth, being responsible for many great and giant earthquakes, including the 2004 Indian Ocean earthquake and tsunami that killed over 227,000 people. The Sunda megathrust can be divided into the Andaman Megathrust, Sumatra(n) Megathrust and Java(n) Megathrust. The Bali-Sumbawa segment is much less active and therefore does not have the "megathrust" term associated with it.

The 1935 Sumatra earthquake occurred at 09:35 local time on 28 December. It had a magnitude of Mw 7.7 and a maximum felt intensity of VII (Damaging) on the European macroseismic scale. It triggered a minor tsunami.

The 1917 Bali earthquake occurred at 06:50 local time on 21 January. It had an estimated magnitude of 6.6 on the surface-wave magnitude scale and had a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale. It caused widespread damage across Bali, particularly in the south of the island. It triggered many landslides, which caused 80% of the 1,500 casualties.

The 1975 Bagan earthquake occurred on July 8 at 6:34 pm local time in Bagan, Myanmar. Many important stupas and temples were destroyed. The strongest intensity was felt in the towns of Nyaung-U, Pakokku, and Yesagyo, and in the Myaing townships on the confluence of the Ayeyawady River. Damage was also reported in Chauk and Natmauk townships. It had a magnitude of Mw 7.0.

The 1907 Sumatra earthquake occurred on January 4 at 05:19:12 UTC. The re-estimated moment magnitude (Mw) is 8.2 to 8.4, with an epicentre close to Simeulue, off Sumatra. An earlier study re-estimated a surface-wave magnitude (Ms) of 7.5 to 8.0. It triggered a widespread and damaging Indian Ocean wide tsunami that caused at least 2,188 deaths on Sumatra. The low observed intensity compared to the size of the tsunami has led to its interpretation as a tsunami earthquake. Higher levels of shaking observed on Nias are attributed to a large aftershock, less than an hour later. The tsunami gave rise to the S'mong legend, which is credited with saving many lives during the 2004 earthquake.

An earthquake affected the island of Java, Indonesia on 22 January 1780. The source and magnitude of the earthquake remains debated among seismologists. Proposed origins of the earthquake include shallow inland back-arc thrusting along a fault located within the upper crust on the island or rupture of the subduction zone off the southern coast of Java. The magnitude of the earthquake is estimated to be at least 8.5, while other sources usually refer to it with a range of Mw  8.0 to 8.5 for the megathrust earthquake. For the shallow crustal earthquake source, the magnitude range is Mw  7.0 to 8.0.
