Maninjau Lake is a caldera lake located in Agam, West Sumatra. This lake was formed from the volcanic activity of Mount Maninjau Purba about 60,000 years ago. The volcanic material resulting from the eruption is scattered and deposited in various pla

Despite immense progress in the last decades, the Holocene climate evolution is still poorly resolved, in particular in the tropics, and especially from a terrestrial perspective. Here we reconstruct 11 000 years of paleo-climate and environment in t

The quasi-biannual oscillation (QBO) dominates the equatorial zonal wind in the tropical stratosphere. Alternating easterly and westerly wind regimes form in the upper stratosphere and propagate downwards to the tropopause with a mean period of appro

Summary The Indo-Pacific Warm Pool (IPWP) climate and related monsoon systems directly affect approximately half the global population, and knowing their past behaviour is crucial for the understanding of our climate system and potential future chang

Volcanic ash is dispersed into the air when an eruption occurs, whilst the magma that reaches the surface of the Earth cools to form igneous rocks before eventually breaking down to form sedimentary rocks. One of the places where the sedimentation of

Peatlands are formed from the accumulation of organic matter that originate from weathering vegetation for a long time. Minerals within peatlands can come from volcanic ash and consist of several types of minerals, one of which is magnetic minerals.

Peatlands in Lake Diatas can store various types of minerals. One of the mineral phases that can be found in peatlands are magnetic minerals derived from volcanic eruptions. This study was used to determine concentration of magnetic minerals found in

Lake Maninjau was formed after a caldera forming eruption ∼50,000 years ago. Eventhough this eruption is one of the biggest Quarternary eruptions on Sumatra, it is not studied in detail so far. Only few attempts to study the volcanic processes have

The rocks on the surface of the earth have different formation process, beginning with the lava of volcanic activity that flow on the surface of the earth and then cool down forming igneous rocks. Rocks derived by volcanic eruptions contain different
