Dubbi volcano in Eritrea is a large volcanic massif rising 1625 m above the the western shore of the Red Sea. It is located in the Afar triangle south of the crystalline basement rocks in the Danakil Alps east of the Danakil depression and east of the Erta Ale range.
The two most-recent eruptive centers are fissure systems that extend NW-SE and NNE-SSW. The former produced lava flows that reached the Red Sea in 1400 AD. The second created 19 small craters at the summit in 1861. Ash fell more than 300 km from the volcano. Two villages were destroyed and more than 100 persons were killed during Africa's largest eruption in historical time. Lava flows from the 1861 eruption traveled as far as 22 km and reached the coast.
An eruption on 12 June 2011 from neighboring Nabro was originally believed to be from Dubbi. -> See whole entry

The middle crater has a hot lake with solfataras along its shore. The lower northern crater has a small, cold lake and is separated from the middle crater by a narrow ridge.
Historical activity has been recorded since the late 18th century and consisted in small to moderate explosive eruptions from the summit craters. Intense fumarolic activity occurs in the summit craters of Ebeko and on the outer flanks of the cone, as well as inside lateral explosion craters. -> See whole entry
Ebulobo (also called Amburombu or Keo Peak), is a symmetrical stratovolcano in central Flores Island. It has a flat summit lava dome and contains a 250 m summit crater, breached on 3 sides. In 1830, a lava flow (known as Watu Keli lava flow) descended from the northern breach on the summit and reached 4 km length.
A small summit eruption occurred on 28th February 1969, where "fire", steam and ash were reported.
Mount Ediziza in NW British Columbia, Canada is a large, complex stratovolcano about 1 million years old forming the most recently active of a group of overlapping basaltic shields, lava domes, flows, and central stratovolcanoes. Mount Edziza contains a 2-km-wide, ice-filled summit caldera with a central summit crater and several flank vents. The volcano's lavas range from basalt to rhyolite.
Frequent volcanic activity of the complex has been going on for about 8 million years, but the last eruptions occurred only about 1000 years ago.
After the Level Mountain Range to the north, Edziza is Canada's second largest young volcano.
Volcanic activity of the Edziza complex is caused by extension structures in the underlying basement and the volcano lies along a zone of north-south normal faults east of the Coast Crystalline Complex.
Active or recently active warm springs are found in several areas along the western flank of the volcanic plateau, including Elwyn springs (36°C), Taweh springs (46°C), and inactive springs near Mess Lake. All 3 hydrothermal areas are near the youngest lava fields on the plateau and are probably associated with the most recent volcanic activity at Mount Edziza.
The vast plateau has also been an important cultural resource. The Tahltan people, who now live largely near Telegraph Creek, British Columbia, used volcanic glass (obsidian) from Mount Edziza to make tools and for trading material.
More recently, most of the plateau has been made into a provincial park to preserve the volcanic and culture treasures unique to the northern British Columbia area. -> See whole entry
Ekarma stratovolcano forms a small 5 x 7.5 km island 8.5 km north of Shiashkotan Island in the northern Kurile Islands, Russia.

It contains two overlapping basaltic-andesite to andesitic volcanoes, with the western one showing historical activity. Lava flows have flown 3 km in all directions from the summit of the younger cone to the sea, forming a sinuous shoreline.
The island summit is formed by a lava dome which formed in the first historic eruption of Ekarma between 1767-69.
El Aguajito volcano (also known as Santa Ana caldera) is a large 10 km wide caldera at the coast of the Gulf of California, northwest of the older La Reforma caldera. The caldera formed during massive eruptions about 7600,000 years ago in what would be called a super-volcano eruption, and its rim is no longer exposed. A series of lava domes that formed about 500,000 years ago, occupy its northern edge. There is an active geothermal system with hot springs along the southern side of the caldera. -> See whole entry
