Powerful earthquake near coastal villages in Papua New Guinea

A Kinemetrics seismograph, formerly used by th...

Earthquake Report comment :
Heavy earthquake at the southern part of New Britain and on top of the Subduction zone near Atua, Ablingi, Awio and Kalagen, all hamlets at the sea.
NO Tsunami report has been issued by NOAA nor by GDACS.
Although Papua New Guinea has a lot of experience with heavy earthquakes, Earthquake-Report.com calls this earthquake moderately dangerous for damage and injuries.
The hamlets specified above will experience a VI MMI shaking = strong shaking. Most of the houses will have been build in wood and bamboo.

Based on our experiences, it will take a very long time before we will receive news. As there are no roads in the area, eventual rescue teams mostly reach the villages by walking ! PNG, one of the poorest nations in the world,  does not have enough equipment to do it otherwise, a shame for the international community. P.N.G. experiences regular heavy to very heavy earthquakes and almost nobody cares about it !

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.

Indonesia massive M 7.5 earthquake – Hardest hit : Mentawai Islands

Earthquake Report comment :

Latest news on this massive earthquake – Click here

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.
