    Opis:
    The earthquake has most horrific and devastating effects on earth as it causes building collapse, destruction of the communication transportation infrastructure system. It further creates the natural disaster like the landslide, soil liquefaction, tsunamis; sometimes can cause enormous fire incident. There are advanced studies and new technologies are being developed to fully understand the phenomenon of the earthquake and its effect, mitigation process, and early prediction. Other bodies in planet, moon or star also experience quake. The seismometer reading from Apollo mission is still being studied to know more about lunar seismology. This study will review earthquake and moonquake as the general introduction, effects, terminology, characterization and shows the relation between these on the bases of some excellent studies done by researchers.

    Opis:
    This paper discusses a list of information and issues that causes of structural failure of buildings. Structural failure begins to occur when the material is stressed to its upper strength limit causing to rupture or extreme deformations. The ultimate strength of the material or the system is the limit of the load bearing capacity. On reaching this limit, the construction materials could already been damaged, and their load carrying capacity is suddenly decreased permanently. If the system is properly designed, a local collapse should normally not be a cause of instant or gradual failure of the complete building. The ultimate failure strength of the construction elements should be carefully considered in the design of structures to prevent failure.

    Opis:
    Three hundred and thirty earthquakes data sets within a period of twenty-six years (1990 -2016) were obtained for the Mid-Atlantic Ridge and East African Rift. The data were analyzed using Seismic Analysis software (SEISAN 9.0) and Microsoft Excel, and the results showed that the earthquakes occur more at a focal depth of 10 km. The body wave magnitude for EAR ranged between 4.1 to 6.6 with a dominant magnitude range of 4.5 - 4.9 and 5.0 – 5.4 having 53 and 52 (32%) occurrences respectively. mb for MAR ranged from 4.1 to 6.4 and recorded a dominant magnitude range of 4.5 – 4.9 and 68 (41%) occurrences. Surface wave magnitudes for EAR and MAR ranged from 4 to 7.2 and 4.1 to 7 respectively while their dominant Ms range was 4.5 – 4.9 with 18 (28%) and 26 (34%) occurrences respectively. Moment magnitude for EAR and MAR ranged from 4.7 to 7.1 and 4.9 to 6.8 respectively while their dominant range was 5.0 – 5.4 with 29 (45%) and 37 (49%) occurrences respectively. Monthly time occurrence showed that EAR had more earthquakes occurring in March while MAR recorded highest occurrence in August. Empirical relationship between correlated magnitudes for EAR and MAR were obtained. The b-values for EAR and MAR were 0.77 and 0.83 respectively while stress drop values within these regions ranged from 2.2 – 51.1 bar, with an observed radius of rupture between 7.0 – 14.4 cm.
