Indonesia massive M 7.5 earthquake – second big M 6.2 aftershock

Earthquake Report comment :
Again a powerful shallow aftershock. The strongest so far.
Preliminary records show that the epicenter is again located on the southern edge of South Pagai.
After analyzing satellite pictures we assume that the most important inhabited village is located at the northern side of South Pagai. This location has not been directly hit so far. On the satellite pictures we can see a limited number of modern buildings.

Powerful 6.1 aftershock hits Pagai Island again

Earthquake Report comment :
Powerful aftershock with a preliminary epicenter at the eastern shores of Mentawai Island South Pagai.
GDACS has just issued a GREEN earthquake alert for this earthquake = very limited chance on damage and/or injuries.
Earthquake-report.com takes this aftershock very serious, as the epicenter is under the island and as eventually earlier damaged buildings from the main quake might collapse. Calculated models from USGS are expecting again a MMI of VI to VII.

Most important Earthquake Data:
Magnitude : Mw 6.1

Indonesia massive M 7.5 earthquake – USGS increases Magnitude to 7.7!

USGS has increased the Magnitude of the earthquake to M 7.7.

This makes this (shallow) earthquake one of the most powerful that occurred this year and even more powerful than the Haiti and the China earthquakes, both with huge numbers of casualties. Contrary to what most agencies are reporting at the moment, this earthquake will have shock-waves from at least VII MMI (very strong shaking).

Luckily the epicenter of the quake has been confirmed about 30 km out of the coast of southern Pangai.

Local Indonesian Sumatra press has still no news from the Pagai islands. They indicate that the mainland did not experience a big earthquake which was previsioned from the beginning by the seismology agencies.
We guess that it will take another 8 to 12 hours before mainland can make more inspections during daylight.

16:20 UTC UPDATE :
No news from the islands which where the most hit so far. We maintain our RED earthquake level as we predict that the shaking would have been very strong on South Pagai. Luckily, this island is scarcely populated. The lack of modern cities with stone and concrete buildings can be the fortunate element in this massive earthquakes. As far as we can see, most villages on the islands are rather primitive and have wooden houses.  Lets hope that this earthquake will not come in our extensive list of  “deadly earthquakes”.

16:04 UTC UPDATE :
2 Aftershocks measuring M 5.2 have hit the same greater epicenter area. We expect that many more aftershocks will hit the same area the coming hours, days and even weeks

15:44 UTC UPDATE : INDONESIAN GOVERNMENT LIFTS TSUNAMI ALARM.
As expected by Earthquake-report.com,  the Indonesian government  has lifted the tsunami alarm quite soon. All simulations gave only limited tsunami waves on nearby islands which have been reached soon after the first very heavy shock.

We will have to anxiously wait until reports from the islands are coming in.
Pagai island will have experienced a STRONG to VERY STRONG shaking of VII to VIII Modified Mercalli.
USGS has no demographic data on Pagai.
Sumatra mainland will be escaping the heaviest shocks of this earthquake as only IV will be experienced in the nearest towns of the island. Padang with 840,000 inhabitants and Bengkulu with 310,000 inhabitants will be rather safe.
Following the demographic data from GDACS it is expected that 1,817 people live in an radius of 50 km around the epicenter. 23,877 in a radius of 100 km and 413,617 in a radius of 200 km. This data is preliminary as the exact location of the epicenter has still to be calculated.
Pagai is part of the Mentawai Islands. All Mentawai Islands had a sensus count of 38,300 inhabitants.

The Mentawai Islands are a chain of about seventy islands and islets off the western coast of Sumatra in Indonesia. Siberut (4,030 km²) is the largest of the islands. The other major islands are Sipura, North Pagai (Pagai Utara) and South Pagai (Pagai Selatan). The islands lie approximately 150 km off the Sumatran coast, across the Mentawai Strait. The indigenous inhabitants of the islands are known as the Mentawai people. The Mentawai Islands have become a noted destination for surfing. (Source Wikipedia)

Origin of the earthquakes
The Mentawai Islands lie above tha Sunda megathrust, a seismically active zone responsible for many great earthquakes. This megathrust runs along the southwestern side of Sumatra island, forming the interface between the Eurasian Plate and Indo-Australian Plate.
Earthquake and tsunami activity has been high since the 2004 Indian Ocean earthquake.
In 1833, the region was hit with an earthquake possibly similar in size to the 2004 Indian Ocean Earthquake[2] and also another large one in 1797.

NOAA Tsunami bulletin EVALUATION

 A DESTRUCTIVE WIDESPREAD TSUNAMI THREAT DOES NOT EXIST BASED ON
 HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

 HOWEVER - THERE IS THE POSSIBILITY OF A LOCAL TSUNAMI THAT
 COULD AFFECT COASTS LOCATED USUALLY NO MORE THAN A HUNDRED
 KILOMETERS FROM THE EARTHQUAKE EPICENTER. AUTHORITIES FOR THE
 REGION NEAR THE EPICENTER SHOULD BE AWARE OF THIS POSSIBILITY.
 AREAS FURTHER FROM THE EPICENTER COULD EXPERIENCE SMALL SEA
 LEVEL CHANGES AND STRONG OR UNUSUAL COASTAL CURRENTS.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

As far as we can see on the simulation, the tsunami waves may have been the strongest on the shores of the nearby islands (see GDACS simulation. The simulation gives NO warning for other places in the sea.
