An earthquake [1] of moment magnitude (Mw) 6.3 that the Java central part earthquake (I ask Java) occurred in the Java central part of Indonesia at (at Japan time 7:53:58 a.m. UTC26 day 22:53:58) at 5:53:58 a.m. of the time in western Indonesia on May 27, 2006.

Mechanism of the earthquake
It is thought that it is activity of the active fault which lies across the Java central part in the north and south currently to have produced this earthquake.
There is an active fault (オパック dislocation) affecting north and south number 10km on the east side of the Jogjakarta city area. The first earthquake of M6.2 was generated at the south end of this dislocation, and an earthquake of M6.1 occurred just after that in the northeast, and shaking continued. Therefore, in the neighborhood including the バンドゥル prefecture in northern dislocation, two shaking interferes it and are amplified, and it is considered that shaking grows big, and damage concentrated on it.
Damage situation
According to CNN so far of approximately 3,500 the death was confirmed, and 20,000 or more got injured. The person who is in state that it is serious in an injured person has a pain [2]. Dead person 2,091 people, the injured person in the バントゥル district counted 1,892 soon [3].
The news report of the BBC pointed out the number of dead people that with it more than 3,000 [4].
The number by Le Monde and the communication in France was approximately similar, too [5].
The number of dead people rose to 3,505 people, and, according to the staff of the Indonesian social ministry, two-thirds of those seemed to produce it in バントゥル [6]. Approximately 5 million people lived in a radius of less than 50km from the epicenter [7].
Most of the ruins of Borobudur which were an ancient pagoda were unhurt, but Prambanan Temple Compounds of Hinduism remains was damaged, and a part was damaged [8].
Because the epicenter was the inland gathering of the island, it became so-called earthquake directly above the focus. At the southern village of Jogjakarta near the seismic center, it is considered that it was a little less than six from a seismic intensity of an upper 5 when I repair it in a seismic scale of Japan.
Because quake resistance was low in the plain house which only piled up a brick, and basics of plaster reinforcement was weak, in a village and the residential area near the epicenter, more than 95% of houses became debris with an earthquake occurrence instantly. There was not a reinforcing rod, and, in the concrete large commercial facilities, the short thing collapsed, and a wall collapsed. Therefore it is likely that so-called earthquake disaster orphan produces most of the victims by suffocation by the collapse of the building.
Influence of other earthquakes
The Mt. ムラピ in the neighborhood lets activity become active and erupted several days before an earthquake, but I am considered to have nothing to do with this eruption activity directly. However, there is a report that volcanic activity becomes active by this earthquake. [8]Because Indonesia is located along so-called circum-pan-Pacific volcanic belt, originally it is the land where the eruption of an earthquake and the volcano is frequent.
Australian plate of the south side and the Eurasia plate of the north side hit the south Indian Ocean of Java, and the earthquake of magnitude six classes was taking place around the epicenter once in several decades. As mechanism, an Indian Australian plate sinks to Eurasia plate, and an earthquake is generated when the distortion of the Eurasia plate was broken off.
If there is the thing waking up a huge plate border type earthquake such as the Sumatra offing earthquake for form of the cancellation of the distortion, there is the thing waking up a dislocation type earthquake such as this earthquake.
Furthermore, by a dislocation type earthquake of the wide gap model that this earthquake was hard to generate a tsunami, the Sumatra offing earthquake was the reverse fault-shaped plate border type earthquake that a tsunami was easy to occur.
In South Pacific area and the Indian Ocean eastern part, the big earthquake of the scale performs frequent occurrence [9] since 2003, and there is a viewpoint that the India plate and the Australia plate, the Eurasia plate, the Pacific plate located in this neighborhood entered in a season.
※About this, a single earthquake and the opinion to do are convincing.
In addition, I may think that dislocation destruction merely went northeast. It greatly varies among researchers about the length of the fault plane. It is cited in this for a thing, the damage that a seismometry network does not develop in thing, Indonesia where a position of the オパック dislocation is not pinpointed that the scale of the earthquake has difficult analysis small.
I can explain the damage in northern dislocation from Mayor of dislocation having been long, geological feature structure, and the identification of the cause is difficult. In addition, in around オパック dislocation, the ground is weak from sediment of the ムラピ volcano origin.
