1) Surface Faulting

Acceptance criteria:

Distance of active fault (considered as supposed

capable fault) to potential site should be ≥ 5 km

Capable faults is not toward to the site

Note : Fault is considered to be capable if younger than 120,000 years old or younger than Middle Pleistocene.

2) Seismicity

 Acceptance criterion:

 Peak Ground Acceleration (PGA) is defined to be ≤ 0.4 g,

in order to minimize the NPP construction cost

 The data used in the seismicity analysis are obtained from

the earthquake catalog data in Indonesia. The data has been tabulated by the Incorporated Research Institute for Seismology (IRIS) since 1964 to 2008 from various sources, such as the USGS / NEIC, ISC, Harvard, and other

databases. Other data obtained from the Novosibirsk

Tsunami Laboratory of the year 1770 to 2001, and from the damage earthquake catalog of Geology Board from 1833 to 2006, and the calculated data of focal mechanism solutions from Harvard CMT catalog.

3) Subsurface Material

 The purpose of subsurface material investigation is to acquire the

geotechnical characteristics and the soil profile of the site

 Based on the secondary data available, it can be concluded that:

 North coast of Banten and West Java Province is lying on alluvial deposits

which are defined as from unconsolidated to semi consolidated material. Meanwhile, the land of Pulau Panjang, a small island in the northern Banten Province, is lying on the coral reefs which are regarded as relatively hard material

 Sediment on the north coast of Banten and West Java Province is more than

200 m thick. Quarternary rocks compose of clay with sand intercalation are at depth 0-230 m.

 The whole interest area are not in danger of ground movement events  Bojonegara, Pulau Panjang, Tanjung Pontang and Cibuaya area are not lie in

liquefaction zone.

 Liquefaction events on the north coast of Banten and West Java Province have never

been reported.

4) Volcanism

 Definition of Capable Volcano:



Historical volcanic activity (volcanic activity 1600 a.d., Indonesia type A)



Manifestation of magmatic activity at present (Indonesia: Type B and C). Type B is characterized by its cone morphology, while type C is characterized by fumarolic activity but unclear cone morphology



Last activity time < maximum repose interval



Quaternary Composite Type, Pliocene Caldera Type

 Criteria



Potential site is not laid in the SDV radius of capable volcano such as phyroclastic flow, phyroclastic fall, lava flow

Flowchart of Volcanic Hazard Analysis

Initial scoping Characterize sources

f volcanic activity

as initiating events Hazards screening Evaluate hazards at site Volcanism <10Myr In appropriate region? Is there current volcanic activity? Is there Holocene volcanic activity? Site suitability decision, inputs for design basis

Not a design basis event: no further investigation needed

Yes Yes Yes No No No Potential for any volcanic hazard at the site? Develop site- specific Volcanic Hazard Model

STAGE 1 STAGE 2 STAGE 3 STAGE 4

Yes No Yes If not, (i.e. 10 Myr to 0.01 Myr), is future volcanic activity credible?

Increasing need for substantiation

Volcano(s) capable No

5) Coastal Flooding

1. Eustacy
2. Tsunami
3. Tides
4. Extreme weather condition
5. Land subsidence

The site is not flooded as high as 1 meter or more in 100 years coming not affected by tsunami wave due to historical tectonic earthquake and undersea volcanic activity

Influenced items Acceptance Criteria

SLIDE 22

 Eustacy

Eustacy of sea-level rise is caused by the addition of the water volume due to ice melting as well as thermal expansion due to increased water temperature

SLIDE 23

Coastal Flooding Modelling in Area of Study Caused by Eustacy

The modelling was based on worst scenario of global sea level rising of 1cm/year after 100 years

* The red color presents the flooded area

SLIDE 24

 Tsunami

Tsunami attributable to volcanic which was caused by the collapse of

Krakatoa caldera in year 1883 occurred in Sunda Strait.

Tsunami attributable to tectonic was caused by tectonics related to

subduction zone happened in the far south.

Tectonic tsunami which is not related to subduction zone occurred in

Sunda Strait such as the Panaitan tsunami. Flooded Area Affected by Krakatoa Tsunami

SLIDE 25

6) River Flooding

Acceptance criterion: The site is not flooded by river flooding as high as 1 meter or more with return period of 100 year.

SLIDE 26

7) Other External Hazard

Other External Hazard Zone Other external hazard consist of coastal abration, uplifting, extreme meteorological events, gas emission and forest fires.
