This Keyword List Contains Indian Ocean Place Names of Coral Reefs, Islands, Bays and Other Geographic Features in a Hierarchical Structure
CoRIS Place Keyword Thesaurus by Ocean - 8/9/2016 Indian Ocean This keyword list contains Indian Ocean place names of coral reefs, islands, bays and other geographic features in a hierarchical structure. For example, the first name on the list - Bird Islet - is part of the Addu Atoll, which is in the Indian Ocean. The leading label - OCEAN BASIN - indicates this list is organized according to ocean, sea, and geographic names rather than country place names. The list is sorted alphabetically. The same names are available from “Place Keywords by Country/Territory - Indian Ocean” but sorted by country and territory name. Each place name is followed by a unique identifier enclosed in parentheses. The identifier is made up of the latitude and longitude in whole degrees of the place location, followed by a four digit number. The number is used to uniquely identify multiple places that are located at the same latitude and longitude. For example, the first place name “Bird Islet” has a unique identifier of “00S073E0013”. From that we see that Bird Islet is located at 00 degrees south (S) and 073 degrees east (E). It is place number 0013 at that latitude and longitude. (Note: some long lines wrapped, placing the unique identifier on the following line.) This is a reformatted version of a list that was obtained from ReefBase.

Along the Sumatran Fault System Derived from GNSS
Ito et al. Earth, Planets and Space (2016) 68:57 DOI 10.1186/s40623-016-0427-z LETTER Open Access Co‑seismic offsets due to two earthquakes (Mw 6.1) along the Sumatran fault system derived from GNSS measurements Takeo Ito1* , Endra Gunawan2, Fumiaki Kimata3, Takao Tabei4, Irwan Meilano2, Agustan5, Yusaku Ohta6, Nazli Ismail7, Irwandi Nurdin7 and Didik Sugiyanto7 Abstract Since the 2004 Sumatra–Andaman earthquake (Mw 9.2), the northwestern part of the Sumatran island has been a high seismicity region. To evaluate the seismic hazard along the Great Sumatran fault (GSF), we installed the Aceh GNSS network for the Sumatran fault system (AGNeSS) in March 2005. The AGNeSS observed co-seismic offsets due to the April 11, 2012 Indian Ocean earthquake (Mw 8.6), which is the largest intraplate earthquake recorded in history. The largest offset at the AGNeSS site was approximately 14.9 cm. Two Mw 6.1 earthquakes occurred within AGNeSS in 2013, one on January 21 and the other on July 2. We estimated the fault parameters of the two events using a Markov chain Monte Carlo method. The estimated fault parameter of the first event was a right-lateral strike-slip where the strike was oriented in approximately the same direction as the surface trace of the GSF. The estimated peak value of the probability density function for the static stress drop was approximately 0.7 MPa. On the other hand, the co-seis- mic displacement fields of the second event from nearby GNSS sites clearly showed a left-lateral motion on a north- east–southwest trending fault plane and supported the contention that the July 2 event broke at the conjugate fault of the GSF. -

The last earthquake which has been occurred near Mentawai archipelago on March 2, 2016 caused panic at the several big cities such as Padang and Meulaboh. Seismic gap in Sumatera subduction zone still has energy to cause tsunamigenic earthquake. Then the west coast of Sumatera Island has been at high risk for tsunami disaster. However, some cities, such as Tapaktuan, were not damaged by 2004 tsunami and others after 2004. These cities locate behind small islands. Therefore many residents believe that the islands will protect the cities against tsunami. -

The largest and best documented are the events of 1770 and 1859 in the Molucca Sea region, of 1629, 1774 and 1852 in the Banda Sea region, the 1820 event in Makassar, the 1857 event in Dili, Timor, the 1815 event in Bali and Lom- bok, the events of 1699, 1771, 1780, 1815, 1848 and 1852 in Java, and the events of 1797, 1818, 1833 and 1861 in Sumatra. Most of these events caused damage over a broad region, and are asso- ciated with years of temporal and spatial clustering of earthquakes. The earthquakes left many cit- ies in ‘rubble heaps’. Some events spawned tsunamis with run-up heights .15 m that swept many coastal villages away. 2004 marked the recurrence of some of these events in western Indonesia. However, there has not been a major shallow earthquake (M ≥ 8) in Java and eastern Indonesia for the past 160 years. -

Many natural and cultural tourism objects are served by Banyak Island. There are 99 islands in the cluster of islands, many of which are very feasible to be developed into mainstay tourist objects, including the natural beauty of the underwater world and green turtles. This study aims to analyze the condition of Banyak Island in terms of attractions, amenities, accessibility, and tourism management as well as to provide alternative development strategies for tourism objects. The method used in this research is a qualitative approach, namely research that produces descriptive data with data collection techniques through interviews, observation, and documentation. The results of this study show that the government's strategy is formulated in developing the Banyak Island tourism area are by utilizing human resources/community in the management of tourism areas, Strengthen the area by optimizing services, infrastructure, stakeholders, and human resources, and by providing supporting documentation for the management of tourism on Banyak Island, intensify the promotion of the Banyak Island Tourist Destination and other Aceh Singkil Regency tourism areas. -

A Test for the Mediterranean Tsunami Warning System Mohammad Heidarzadeh1* , Ocal Necmioglu2 , Takeo Ishibe3 and Ahmet C
Heidarzadeh et al. Geosci. Lett. (2017) 4:31 https://doi.org/10.1186/s40562-017-0097-0 RESEARCH LETTER Open Access Bodrum–Kos (Turkey–Greece) Mw 6.6 earthquake and tsunami of 20 July 2017: a test for the Mediterranean tsunami warning system Mohammad Heidarzadeh1* , Ocal Necmioglu2 , Takeo Ishibe3 and Ahmet C. Yalciner4 Abstract Various Tsunami Service Providers (TSPs) within the Mediterranean Basin supply tsunami warnings including CAT-INGV (Italy), KOERI-RETMC (Turkey), and NOA/HL-NTWC (Greece). The 20 July 2017 Bodrum–Kos (Turkey–Greece) earth- quake (Mw 6.6) and tsunami provided an opportunity to assess the response from these TSPs. Although the Bodrum– Kos tsunami was moderate (e.g., runup of 1.9 m) with little damage to properties, it was the frst noticeable tsunami in the Mediterranean Basin since the 21 May 2003 western Mediterranean tsunami. Tsunami waveform analysis revealed that the trough-to-crest height was 34.1 cm at the near-feld tide gauge station of Bodrum (Turkey). Tsunami period band was 2–30 min with peak periods at 7–13 min. We proposed a source fault model for this tsunami with the length and width of 25 and 15 km and uniform slip of 0.4 m. Tsunami simulations using both nodal planes produced almost same results in terms of agreement between tsunami observations and simulations. Diferent TSPs provided tsunami warnings at 10 min (CAT-INGV), 19 min (KOERI-RETMC), and 18 min (NOA/HL-NTWC) after the earthquake origin time. Apart from CAT-INGV, whose initial Mw estimation difered 0.2 units with respect to the fnal value, the response from the other two TSPs came relatively late compared to the desired warning time of ~ 10 min, given the difculties for timely and accurate calculation of earthquake magnitude and tsunami impact assessment.
