Map top and plot bottom of the seismicity recorded during July at Katla.

Colors indicate the timing of epicenters and their respective plotted magnitudes, recorded as late as on 9 July , according to the scheme shown below the map.

Black triangles indicate seismic monitoring stations. Figure 6. The plots show rising water level and conductivity that were coincident with peak harmonic tremor.

Azores May Green Volcanoes The Azores are famous for their very pleasant climate, breathtaking green and unspoiled landscapes and nature. Guided by a photographer and volcanologist, discover five islands: Sao Miguel, Faial, Terceira, Pico and Flores - each with its distinct character. Volcano Calendar We're proud to present our volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.

Daily volcano map. Katla erupted very powerfully in but there has been evidence of smaller eruptions since then. Icelandic volcanologists are expecting another eruption in the next few years, so Myrdalsjokull and the Katla caldera are being monitored quite closely.

Katla volcano is subglacial, basaltic-to—rhyolitic, and it has the reputation of being one of the most dangerous volcanoes of Iceland. The eruption lasted years. Katla is about 30 km in diameter with a crater of 10 km in diameter. Within Katla caldera, situated beneath the centre of Myrdalsjokull, the ice is hundreds of metres thick.

The caldera is oval in shape with the longest axis NW-SE up to m deep, covering an area of km2. During the summer of some activity was noted within the Myrdalsjokull caldera. After the flood, existing depressions enlarged and crevasses were formed.

The depressions became deeper during the summer and increased in number.
