Volcano Calendar 2015: We're proud to present our new volcano calendar 2015: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
Lassen (or Lassen Peak) volcano in northern California is located at the southern end of the Cascade Range. Besides Mt St. Helens, it is the only volcano in the contiguous US that erupted in the 20th century.
Lassen's summit complex is a lava dome that rises 2,000 feet (610 m) above the surrounding terrain and has a volume of half a cubic mile, making it one of the largest lava domes on Earth. Its summit is a complex area of several craters.
Lassen Peak is the largest and youngest of a group of more than 30 volcanoes that have erupted in the Lassen Peak area over the past 300,000 years.

Location of recent earthquakesSE of Lassen volcano (USGS data)
A shallow magnitude 5.7 earthquake occurred Fri, 24 May at 04:58 UTC km WNW of Greenville, California, about 50 km SE of Lassen volcano. Hundreds of aftershocks, some of them felt, have occurred. It is unlikely that the earthquake has any relation with the volcano. The status of Lassen volcano remains therefore at green.
Kelut volcano's lava dome in 2007: One of the most impressive lava dome eruptions in recent years. A new dome formed in the crater lake of Kelut volcano (East Java) in late 2007. Enjoy some unique pictures.
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
