Significance We present a high-resolution, replicated speleothem δ 18 O record from Klang Cave in southern Thailand that characterizes rainfall variation NCIP over the past 2,700 y. This reveals notable dry climate conditions during current and warm periods, similar to observations SCIP, which resemble enhanced El Niño-like conditions. Using newly developed ITCZ shift index, we find southward shifted early MWP CWP. Our results suggest detecting changes due anthropogenic forcing still remains...
Since 1963, the International Heat Flow Commission has been fostering compilation of Global Database to provide reliable heat-flow data. Over time, techniques and methodologies evolved, calling for a reorganization database structure reassessment stored Here, we results collaborative, community-driven approach set-up new, quality-approved global database. We present background information on how is determined this important thermal parameter could be systematically evaluated. The latter...
In the fields of atmospheric and climate science, there is growing use machine learning global circulation models. These approaches are becoming increasingly sophisticated with availability extensive ground-based remotely sensed datasets. However, both rely on large spatial temporal For over half a century, stable isotopes oxygen hydrogen have been used as robust proxies for understanding hydrometeorological processes, acting conservative tracers land-ocean-atmosphere interactions. these...
Abstract Peninsular Malaysia is tectonically situated on a stable craton (intraplate) and so far experiences relatively little earthquake activities, thus considered as region with low seismicity. This study uses data from 59 events obtained various sources in the period 1922 to 2020. The overall seismicity area expected due general intraplate setting. Earthquakes occurred onshore offshore of between latitudes 1° 7° N longitudes 99° 105° E. pattern shows that epicenters are distributed...
The Malaya Peninsula, uniquely positioned between the South China Sea to east and Indian Ocean west presents a unique geographic vantage point for study of ocean-ocean ocean-atmosphere-land interactions, particularly in context climate change. Its proximity Indo-Pacific Warm Pool (IPWP) makes region critical nexus where global temperature rise intersects with significant ocean-atmosphere processes, such as Hadley Walker circulations, El Niño-Southern Oscillation (ENSO), Dipole...
Songkhla Lagoon has been studied for decades, but there is no clear evidence of its origin. As a barrier to the lagoon, Satingpra Peninsula plays crucial role in understanding formation. Eleven sediment samples from sand ridges and tidal flats on Peninsular were collected analysed granulometry geochronology. Both coarse-grained fine-grained quartz-rich fractions utilised prepare aliquots. The optically stimulated luminescence (OSL) dating was performed using single-aliquot regenerative dose...
Abstract Electrical energy demand for Southern Thailand is continuously increasing partly due to an increase in tourism. Around 3,000 MW of coal fired power plants are planned by the government, but proposal was put on hold resistance local communities and civil society groups. Besides this, not only large CO 2 emitters, thus intensifying on-going climate change processes, also require lengthy environmental impact assessments, their technology costs remain stagnant at comparable high levels....
The Phang Nga geothermal area represents a small, moderate temperature, deep circulating system, apparently typical of those associated to hot springs in southern, central and northern Thailand. An integrated geological, geochemical geophysical study was carried out found be useful for understanding subsurface flow characteristics developing conceptual model the system. Resistivity magnetotellurics (MT) data at depth down 500 m define low-resistivity layer with shallow aquifer water....
The shallow subsurface is subject to various human activities, and the place of occurrence geohazards, e.g. active faults. identification location orientation such faults can be vital for infrastructure development. aim this study was develop a low-cost 3D resistivity survey system, with reasonable time fault investigations. area in Songkhla Province, Thailand located an old quarry where could identified outcrops. designed cover expected 100 electrodes arranged 10×10 square grid electrode...
This paper initially reviews the sequence of events surrounding tsunami disaster, which occurred on December 26, 2004, and how this affected Thailand. The authors then consider concepts minimisation after effects, local people, homes, businesses, stock, supplies services, tourism. In these respects, consideration is first given to built environment its operation. Then possibilities for protection, using both natural man-made methods are reviewed. followed by suggestions research projects,...
On 11–13 November 2010, more than 150 participants from four different continents assembled at the 5th International Conference on Applied Geophysics in Phuket, Thailand, a city better known as “Pearl of Andaman Sea.” During conference weather was unusually rainy for that time year, but atmosphere inside Club Beach Resort, venue near Patong beach, vibrant.
Modelling of tsunami in shallow coastal waters involves fast flows which become complex as they reach the shore because seabed and line boundaries, pickup deposit sand, gravel, coral rocks. This results dynamic changes water/seafloor boundaries water/air boundaries. Typically, seafloor may locally deeper or shallower, giving rise to sand banks small islands being removed and/or added. The consequences are further made more by reflections from shoreline solid features, deposition, removal...
Summary Groundwater is vital and thus even more important in areas outside the tap water system of larger cities, e.g. rural or new infrastructure development. In groundwater often not well established making any exploration such a challenge; recent survey Southern Thailand related to project area. Based on overall requirements, including security situation area, 1D resistivity Schlumberger array mode was chosen. Over three days field work four surveys were carried out with AB/2 distances...

Geothermal springs have provided a unique opportunity to study the geothermal system of geological processes. A reservoir temperature estimation based on chemical geothermometers is vitally essential for assessing exploration and development resources. The paper represents various techniques with comparisons between silica (quartz chalcedony) cation (Na–K–Ca K–Mg) high exit (temp. ≥55°C) in southern Thailand. Na–K–Ca geothermometer presented more elevated temperatures than K–Mg, chalcedony...
Summary Communities located on small ocean island often face the issue of freshwater scarcity as usually they depend rainwater. If available, groundwater resources occur in form lenses, which are under constant threat from natural and anthropogenic factors, such rainfall variability, saltwater intrusion, contamination through waste water intensive farming. The size, extend, yield lenses depends various like size island, topography, vegetation, especially an complex subsurface geology. An...
Summary In geothermal systems, heat is generated inside the Earth and reaches surface; with main parameters are thermal conductivity, as well heat, transport properties. A thorough understanding of mass fluids in natural state earth system required. Here codes 'Simulators for HEAT MAss Transport' (SHEMAT) were used to simulate flow water distribution heat. The hot spring at Khlong Thom, Krabi Province, Southern Thailand, was chosen. First, a steady model simulated varied reasonable...
