"Bangunan penyelamat atau yang biasa dikenal dengan escape building dalam penggunaan sehari-hari dapat diperuntukkan sebagai fasilitas umum seperti perkantoran ataupun ruang serbaguna, namun pada saat terjadi bencana gempa dan tsunami maka bangunan ini dapat digunakan sebagai tempat perlindungan sehingga harus dilengkapi dengan kemudahan jalan masuk yang memadai seperti ramp dan tangga. Struktur bangunan penyelamat ini berdasarkan FEMA P646 harus memiliki sistem yang kuat untuk menahan gaya yang ekstrim, sistem terbuka yang dapat mengalirkan air dengan sedikit tahanan, sistem daktail yang menahan gaya yang ekstrim tanpa hancur, dan sistem tak tentu yang dapat mengalami kegagalan parsial tanpa keruntuhan progresif. Bangunan penyelamat berlokasi pada wilayah Banda Aceh dengan kondisi tanah lunak (SE) sehingga didapat Sds 1,05 dan Sd1 0,217. Beban tsunami yang digunakan adalah gaya hidrodinamik, puing (debris impact), dan angkat (uplift). Gaya yang lebih dominan berpengaruh terhadap struktur adalah akibat gaya gempa dibandingkan tsunami yang dapat terlihat dari besaran nilai momen dan shear check.

Building a savior or commonly known as escape building in daily use can be designated as public facilities such as office or utility room, but in the event of earthquake and tsunami is building can be used as a sanctuary and should be equipped with adequate ease of access such as ramps and stairs. Building structure is based on FEMA P646 rescuer must have robust systems to withstand extreme forces, an open system that can drain the water with little resistance, ductile systems that withstand extreme forces without destroyed, and the indeterminate system that can undergo a partial failure without progressive collapse . Rescue building located at the Banda Aceh area with soft soil conditions (SE) to obtain SdS 1.05 and Sd1 0.217. Tsunami load used is the hydrodynamic force, debris (debris impact), and lift (uplift). Style that is more dominant effect on the structure is due to the tsunami earthquake forces than can be seen from the magnitude of the moment and shear check."

"Dealing with volcanic and seismic activity, this book comprises eighteen papers, most of which were presented at an international seminar organized and held at the Complutense University of Madrid in October 2001. It addresses geodetic, geophysical and geochemical effects; monitoring; and theoretical modelling of volcanic and seismic processes."

"The work presented in this thesis is divided two subjects. First, devoted to the behavior, mechanic model, simulation and analysis of plate tectonics under excitation force approximated. Approach of an Earthquake are assumptions on the nature of the rupture process, review the evidence for the essential importance of the flow under plate with the modes of deformations.

Earthquake is primarily a mechanical process which appears as genuire rupture of crust and the earth behaves as an elastic body during the short time span of the phenomena. The friction has probably a fundamental role in the mechanics of the earthquakes. Rock mechanicians consider an earthquake as a stick-slip event controlled by the friction properties of the fault.

During an earthquake, on the nature of the fault and on the effect of trapped fluids within the crust at seismogenic depth, fault zone head seismic waves are generated by a shear-dislocation source and then propagated through the modeled earth medium. Wave propagation theory is used to solve the problem at hand for wave motion response, which is found as the superposition of the mean and scattered wave response.

Second, devoted model of the wave propagation, an important modeling tool of fault zone properties at depth can be provided by accurate simulations of seismic fault zone head and trapped waves for realistic structures. Analytical solutions for seismic wave fields generated by double-couple sources at material discontinuities in plane-parallel structures. Extensive 2D studies of the dependency of fault zone wave motion on basic media properties and source receiver geometries show that there are significant trade offs between propagation distances along the structure, fault zone width, impedance contrasts, source location within.

And the most important applications of the theory of structural dynamics is in analyzing the response of the structures to ground shaking caused by an earthquake. The study for earthquake response of linear SDF systems to earthquake motions concerned the displacement, velocity and acceleration. Then we introduced the response spectrum concept, which is central to earthquake engineering, together with procedures to determine the peak response of systems directly from the response spectrum."

"Penelitian sebelumnya telah menunjukkan bahwa curah hujan dan gempa bumi adalah dua mekanisme utama yang memicu tanah longsor (Keefer, 1984; Schuster et al, 1996;. Crosta, 2004). Untuk tanah longsor disebabkan gempa, banyak telah dilakukan penelitian mendalam tentang identifikasi dan deskripsi tanah longsor coseismal, terutama yang disebabkan oleh gempa bumi bencana ( Keefer, 1984; Harpa et al, 1991;. Jibson et al, 1994;. Harpa dan Jibson, 1996; Khazai dan Sitar, 2004). Pada Rabu,September 30, 2009, jam 5:16, sebuah gempa 7,6 Mw melanda pantai barat Sumatera, yang menyebabkan tanah longsor bidang di tiga desa di Kanagarian Tandikat dan menelan korban jiwa 360 orang. Penelitian ini mengkaji metode perkiraan untuk menentukan pengaruh infiltrasi pada stabilitas lereng dari dua lapisan dan akibat gempa. Ada dua pendekatan: 1.Analisa matematika dengan kondisi jenuh menggunakan model Hijau-Ampt, 2.Analisa numerik dengan kondisi jenuh menggunakan. Hasilnya adalah perpindahan akibat meningkatnya variasi kohesi, Dalam kondisi hujan lebih besar dari kapasitas infiltrasi, hal ini ditunjukkan oleh respon yang lebih besar sebelum hujan dan setelah hujan, dan perpindahan pada bagian lereng lebih besar dari bagian datar. Hal ini berarti variasi kohesi yang disimulasikan infiltrasi air hujan pada tiga kondisi, menyebabkan amplifikasi lokal, hal ini lebih berbahaya karena keberadaan air. Yang paling berisiko tanah longsor jika ada air tanah di lapisan batuan yang memisahkan pasir karena akan berisiko karena bidang tanah longsor mengikuti aliran air tanah.

Previous studies have shown that rainfall and earthquakes are two main mechanisms that trigger landslides (Keefer, 1984; Schuster et al., 1996; Crosta, 2004). For earthquake induced landslides, many studies have been concerned with the identification and description of coseismal landslides, particularly those caused by catastrophic earthquakes (see, for example, Keefer, 1984; Harp et al., 1991; Jibson et al., 1994; Harp and Jibson, 1996; Khazai and Sitar, 2004). On Wednesday September 30, 2009,at 5:16 p.m., an Mw 7.6 earthquake struck the west coast of Sumatra that caused landslides fields in three villages in Kanagarian Tandikat a lost life of about360 victims.

This study examines an approximate method for determining the influence of infiltration on the stability of the two superficial layers of slope. There are two approaches: mathematical 1.Analyse unsaturated conditions with the Green- Ampt model, 2.Numerical analysis of saturated conditions using the program FLAC 3D.

The result is displacement increased as the variation of cohesion In the condition when the rain greater than capacity infiltration showed a greater response conditions before the rain After the rain, and the displacement at the slope section greater than flat section. its means variation of cohesion which is simulated rainwater infiltration at all three conditions, causes amplification of the amplification local, is more dangerous because of the presence of water. Who is most at risk of landslides if there is groundwater in the rock which separates the sand it would be risky because the field of landslides following the flow of groundwater."
