A. News Source from ESDM News

Location:

The Earthquake Disaster in Padang Indonesia at September 29th-30th 2009, has main earthquake 7,6 SR and the next following earthquake in 6,2 SR. As a Fact this earthquake didn't followed by a tsunami (overlarge wave) disaster.

From DESDM Institution announced this earthquake happened because subduction (in area of crash zone from two big plate tectonic) of Indonesian Sea Plate (Australian Plate) under Asian Plate which located along West Coast of Sumatra Island, according USGS it's in subduction zone between Australian Plate and Sunda Plate. (note this Formation of collide is Subduction Form because the two plate which is Sea Plate and Continent Plate, has a Large Differentiation of Density between them. The lower density plate later subducts under the higher density plate).

This Earthquake didnot have ability to produce Tsunami because the epicentre (earthquake source point) deep enought location, and as the result didn't produce Large Power to made a tsunami.

Information from Indonesian Meterolog, Climate and Geophysist Institution (BMKG), this earthquake appeared in afternoon (30/9), at 17:16:09 WIB in 7,6 Scala Richter (SR). Epicentre (earthquke source point) layed on coordinate 0.84 LS - 99.65 BT, 71 Km depth from water sea level, 57 Km far from South West Pariaman, Sumatera Barat. The Second (following) earthquake
appear 22 minutes later, on 17:38:52 WIB in 6,2 SR, Epicentre location on 72 LS - 99.94 BT, at 110 Km depth, 22 Km SouthWest Pariaman, Sumatera Barat.

Other Large Earthquke in September - October in Island Arc Java-Sumatra is on Sukabumi South Java and Later in Sunday October 17th 2009 at Ujung Kulon, Sunda Strait. Both of them caused by Tectonic Plate movement.

From USGS Report (write as in original text) about Padang Earthquake September 30th 2009

Felt Reports

At least 1100 people were killed, 2181 were injured and thousands are still unaccounted for in the Padang area. More than 2650 buildings have been damaged in the area and landslides have disrupted power and communications. Felt (VII) at Padang. Widely felt throughout Sumatra and Java, Indonesia, Malaysia, Singapore and Thailand. A small local tsunami with wave heights of 27 centimeters (amplitude measured relative to normal sea level) was generated.

Tectonic Summary

The southern Sumatra earthquake of September 30, 2009 occurred as a result of oblique-thrust faulting near the subduction interface plate boundary between the Australian and Sunda plates. At the location of this earthquake, the Australian Plate moves north-northeast with respect to the Sunda plate at a velocity of approximately 60 mm/yr. On the basis of the currently available fault mechanism information and earthquake depth of 80 km, it is likely that this earthquake occurred within the subducting Australian Plate rather than on the plate interface itself. The recent earthquake was deeper than typical subduction thrust earthquakes that generally occur at depths less than 50 km. The subduction zone surrounding the immediate region of this event has not witnessed a megathrust earthquake in the recent past, rupturing last in an earthquake of M 8.5 or larger in 1797. Approximately 350 km to the south, a 250 km section of the plate boundary slipped during an Mw 8.4 earthquake in September 2007, while approximately 300 km to the north, a 350 km section slipped during the Mw 8.7 earthquake of March 2005. In early 2008, the plate boundary updip of today’s earthquake was active in a sequence of Mw 5-6 earthquakes. It is not clear how today’s earthquake is related to the sequence of megathrust subduction zone events on the shallower section of the plate boundary.
