Eruption of Paluweh Volcano, Indonesia

8.3S 121.7E

April 1st, 2013 Category: Volcanoes

Indonesia – March 24th, 2013

Ash is projected forth from the summit of the Paluweh (also known as Rokatenda) Volcano in Indonesia. It is carried southwest by winds, over the island of Flores, the Savu Sea and the island of Sumba. The eruption at Paluweh may have been caused by the collapse of an unstable lava dome. The number of small tremors and emissions of ash increased in October 2012 and continued into February 2013, perhaps indicating growth of the lava dome.

Indonesia – March 24th, 2013

An eruption of the Paluweh Volcano caused a thick plume of ash to blow westward and then south, across Flores Island and over the Savu Sea.  High-altitude winds carried airborne ash more than 440 kilometers (270 miles) to the southwest. Paluweh, also known as Rokatenda, is a stratovolcano mountain located on the small Palu’e Island, north of Flores Island in Sikka Regency in the province of East Nusa Tenggara, Indonesia. It is the highest point on the island with a height of 875 metres (2,871 ft).

Italy – March 23rd, 2013

Visible just west of the clouds lining the east coast of Sicily is the snow-capped Mounta Etna volcano, the largest of Italy’s three active volcanoes. The faint grey line that can be seen streaming east-southeastward from its peak is a stream of gas and ash from multiple craters.

Mexico – March 7th, 2013

Popocatépetl Volcano is located just 70 km (43 mi) southeast of Mexico City, Mexico. It is one of the most active volcanoes in Mexico, having had more than 15 major eruptions since the arrival of the Spanish in 1519. Volcanic activity increased again in February 2013, and ash emissions still continue (click here for previous images). A plume (visible in the upper left quadrant) rises to at about 27,000 ft (7 km) altitude (or approx. 1500 m above the crater) and drifts east. The seismic signal shows numerous volcanic quakes, but less tremor.

Plume of Ash and Steam from Popocatépetl Eruption, Mexico

Mexico – March 7th, 2013

Popocatépetl Volcano, southeast of Mexico City (visible as a grey area by the left edge), Mexico, is currently erupting strongly. Here, a white plume of steam and ash fans out as winds carry it eastward. A new lava dome had been observed growing in the volcano’s crater until it was removed by an explosive eruption this morning. Seismograms indicate strong volcanic tremor generated by gas and magma movement (click here for previous images).
