and seismic survey at the TA22 seamount (in the Lau basin, SW Pacific) for finding the submarine hydrothermal deposits in October 2009. We acquired magnetic and bathymetry data sets by suing Overhouser Proton Magnetometer SeaSPY (Marine Magnetics Co.), Multi-beam Echo Sounder EM120 (Kongsberg Co.). We conducted the data processing to obtain detailed seabed topography, magnetic anomaly, reduction to the pole (RTP) and magnetization. Based on the magnetic properties result, we analyzed submarine geology structure of TA22 seamount with post-processed seismic profile. The detailed bathymetry of the TA22 seamount showed the left and right crest parts that have caldera features in each crest central part. The magnetic anomaly distribution of the TA22 seamount regionally displayed high magnetic anomalies in northern part and the low magnetic anomalies in southern part around the caldera features. The RTP magnetic anomaly distribution of the TA22 seamount presented commonly high magnetic anomalies in the each caldera central part. Also, it represented strong anomalies at the inside of caldera rather than outside flank of the caldera. The magnetization distribution of the TA22 seamount showed the low magnetization zone in the center of each caldera, high magnetization zone in the southern and northern east part. From analyzed the seismic profile map, The TA22 seamount area is showed for the inferred small mounds inside each caldera central part and it assumes to make possibility of sills by the magma in cases of the right caldera. Taking into account all results of this study (bathymetry, magnetic anomaly, RTP, magnetization, seismic profile) with rock samples at the left caldera area in 2009 survey, we suppose the possibility of hydrothermal deposits at mounds in each caldera central part and at outside flank of the caldera representing the low magnetization zone. We expect to have the better results by combined modeling from this study data with the other geological data (ex. detailed gravity, 3D seismic, petrologic study results and etc). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=detailed%20bathymetry" title="detailed bathymetry">detailed bathymetry</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20anomaly" title=" magnetic anomaly"> magnetic anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=seamounts" title=" seamounts"> seamounts</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20profile" title=" seismic profile"> seismic profile</a>, <a href="https://publications.waset.org/abstracts/search?q=SW%20Pacific" title=" SW Pacific"> SW Pacific</a> </p> <a href="https://publications.waset.org/abstracts/65090/a-study-on-the-magnetic-and-submarine-geology-structure-of-ta22-seamount-in-lau-basin-tonga" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Seamounts and Submarine Landslides: Study Case of Island Arcs Area in North of Sulawesi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arif%20Rahman">Muhammad Arif Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamma%20Abdul%20Jabbar"> Gamma Abdul Jabbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Enggar%20Handra%20Pangestu"> Enggar Handra Pangestu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfi%20Syahrin%20Qadri"> Alfi Syahrin Qadri</a>, <a href="https://publications.waset.org/abstracts/search?q=Iryan%20Anugrah%20Putra"> Iryan Anugrah Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizqi%20Ramadhandi."> Rizqi Ramadhandi.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia lies above three major tectonic plates, Indo-Australia plate, Eurasia plate, and Pacific plate. Interactions between those plates resulted in high tectonic and volcanic activities that corelates into high risk of geological hazards in adjacent areas, one of the areas is in North of Sulawesi鈥檚 Islands. This case raises a problem in terms of infrastructure in order to mitigate existing infrastructure and various future infrastructures plan. One of the infrastructures that is essentials to enhance telecommunication aspect is submarine fiber optic cable, that has risk to geological hazard. This cable is essential that act as backbone in telecommunication. Damaged fiber optic cables can pose serious problem that make existing signal to be loss and have negative impact to people鈥檚 social and economic factor with also decreasing various governmental services performance. Submarine cables are facing challenges in terms of geological hazards, for instance are seamounts activity. Previous studies show that until 2023, five seamounts are identified in North of Sulawesi. Seamounts itself can damage and trigger many activities that can risks submarine cables, one of the examples is submarine landslide. Main focuses of this study are to identify new possible seamounts and submarine landslide path in area North of Sulawesi Islands to help minimize risks pose by those hazards, either to existing or future plan submarine cables. Using bathymetry data, this study conduct slope analysis and use distinctive morphological features to interpret possible seamounts. Then we mapped out valleys in between seamounts and determine where sediments might flow in case of landslide, and to finally, know how it affect submarine cables in the area. <p
