Abstract
A study on a railway tunnel in the area of Karangkates, Sumberpucung
Subdistrict, Malang District, Indonesia, had been undertaken. This study aims
to detect cracks that may have been filled with water from rain that can be
fatal to the power of the tunnel. This research was conducted with the active
geophysical methods, namely resistivity geoelectrical dipole-dipole
configuration (pseudodepth section). Interpretation of the data acquisitions
was made after further processing. With the merge for each pseudodepth
section, it will be obtained a physical description of the target (tunnel). The
results showed that, rock solid structure (red) is located at the bottom of the
tunnel (rail), while at the top and sides of the tunnel, which is lithologic
structure, is relatively less dense (blue). It is estimated that the are cracks as
well as the distribution of the lens on the ground subsidence above the tunnel.
Another thing is the carrying capacity of the tunnel is dominated by the
presence of cast concrete that is located on the side walls and top of the
tunnel. But the cracks in the top and sides must be taken into account to avoid
the danger of a more fatal in the future, because it was pretty crowded tunnel,
as trains passed from Malang to Blitar cities, and in one of the top of the
tunnel is the path Malang – Blitar buses.
Index Terms— Railway Tunnel, geophysical resistivity, dipole-dipole,
pseudodepth section, Malang, Indonesia.

A hybrid type of grand-canonical Monte Carlo simulation is carried out to
investigate the accommodation of guest molecules inside ice and its influence
to the host structure. The simulation shows that the presence of guest
molecules inside the interstitial space of ice structures can enhance their
stability, which in turn push the envelope of phase boundaries of those ices to
higher temperature and pressure. The quantification of hydrate stability in
term of chemical potential of water, calculated based on extension of van der
Waals-Platteuw theory, lead to the global phase diagram. The influence of
guest molecules inside ice structures also bring unique mechanical properties,
such as positive gradient in compressibility with the increase of pressure
applied to ice II filled with hydrogen. The effect of Lennard-Jones (LJ)
parameter εwg, which mainly determines the strength of van der Waals
interaction, in stabilizing the host structure is also clarified by varying its
magnitude in a series of simulation.
KEYWORDS: Water, Ice, Gas hydrate, Non-bonded interaction, Monte Carlo

Semeru volcano (3676m above sea level) is an andesitic stratovolcano located
in East Java, Indonesia. Summit explosions have occurred continuously since
1967. During this period strombolian and vulcanian type explosions have
occurred, producing explosion plumes rising 400–1000 m above the summit.
We observed some of volcano earthquakes recorded at Semeru volcano in
2009. We analyzed the deep volcano earthquakes known as VA and also
investigated the explosion earthquakes in relation with the different of it’s
visual appearances. The hypocenters of VA with frequency ranged from 3-7Hz
distributed into two clusters. First cluster is distributed at a depth of 3-4km
and the second is about 6-8km which is associated with rising magma to the
surface. The frequency of eruption earthquakes ranged from 0,78 to 4,09 Hz.
Correlation between visual appearances and frequency are as follow; the
eruption earthquakes that is manifested by visual grayish white eruption in
January-February has 0,87 to 3,8 Hz; the eruption earthquakes that is
manifested by the eruption of white visual show ,87-2,64 Hz. Whereas lava
dome growth at the end of 2009, the eruption of earthquake frequency
content of 1.06 to 2.73 Hz. Eruption earthquake hypocenter is located at a
depth of less than 1km below the crater.
Keywords: Semeru volcano, volcanic earthquakes, explosion earthquake,
