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.
Latest quakes in Greece: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
