Comparison of the Kawah Ijen crater lake in 1805 (from Leschenault (de la Tour) (1858)), and the present-day. The main differences are an increase in the size of the lake, a steepening of the eastern crater rim, and the presence of direct lake outflow in 1805. Thebottom mapalso s...
The blast is believed to have deforested parts of India - about 3000 miles away - and ejected about 2600 cubic kilometers of volcanic debris. Today the crater is the world's largest volcanic lake - about 100 kilometers long and 35 kilometers wide. Image composed using Landsat Geocover 2000...
On the basis of literature information and new palynological data from cored crater-lake sediments, in this presentation we briefly address the basic question to what extent the Siberian plant fossil record confirms age-equivalence between ... H Visscher,H Svensen,C Looy,... - Egu General Assemb...

Steps in the formation of Crater Lake Caldera Eruptions of ash and pumice: The cataclysmic eruption started from a vent on the northeast side of the volcano as a towering column of ash, with pyroclastic flows spreading to the northeast. Caldera collapse: As more magma was erupted, cracks ...
The Blue Lake Reservoir in Mount Gambier occupies a volcanic crater and it became the third largest water storage facility in the state of South Australia (Gouramanis et al., 2010). Similarly, in New Zealand, a volcanic maar in Auckland, Lake Pupuke, provides a major water supply for the ...
It is the largest lava barrier lake in China, and the second largest in the world. About 1 million years ago, Lava as a result of volcanic eruption blocked the river bed of the Mudanjiang River forming a lava dam. As a result, the incipient Jingpo Lake began to take shape. In the ...
We tested this approach in 43 samples of a 19,000-year sediment sequence recovered from Lake Rutundu, a volcanic crater lake on Mt. Kenya. Our results show that a significant fraction of the extractable Si is of non-biogenic origin, especially in the part of the sequence deposited during ...
The different intensities of radon trend curves and residuals, lower in MSA than in OLB, are likely due to the different distance of the two sites from the main active degassing area, i.e. Pisciarelli fumarole and Solfatara crater, where the CO2 flux is higher. Furthermore, OLB is inside...
