Volcano Calendar 2018: We're proud to present our 2018 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Sakurajima (also spelled Sakurashima or Sakura-jima, 桜島 in Japanese) volcano in southern Kyushu is one of the most active volcanoes in the world, and one of the few that are at present in constant (persistant) activity. Its ongoing typical activity range from strong strombolian to large ash explosions every 4-24 hours.
The volcano is located across Kagoshima Bay only 8 km east of the city of Kagoshima with a population of half a million. Sakurajima's eruptive history has been recorded since the 8th century. It has frequently deposited ash on Kagoshima, and due to its explosive potential, considered a very dangerous volcano and closely monitored.
The largest historical eruptions of Sakurajima took place during 1471-76 and in 1914.
Sakurajima volcano (Kyushu Island, Japan): explosions continue, volcano back to its typical state of activity

Small vulcanian eruption at Sakurajima earlier today
Since its re-awakening in late March, the volcano seems to be back in its typical activity of intermittent small to moderate vulcanian explosions at rates of typically 2-3 per day. It also seems that since late April, it has picked up again to levels similar as during much of 2013-15, with sometimes larger explosions that generate tall ash plumes of up to 4-5 km height.
Most of the explosions come from the younger Showa crater on the upper eastern flank, although some also occur from the older summit vent Minamidake.
During the past days, 2-3 explosions have occurred each day, with ash plumes that rose to between 5,000 and 13,000 ft (1,500-4,000 m) altitude, i.e. ranging from a few hundreds to approx. 2,500 km.
This activity has has been characteristic of the volcano for most of the past years, with an unusual pause during late July 2016 and March this year.
from the Smithsonian / USGS Weekly Volcanic Activity Report 3-9 May 2017:
During 1-9 May, JMA reported that 9 events at Showa Crater (at Aira Caldera’s Sakurajima volcano) were detected during 1-8 May. One of the events was explosive, generating an ash plume that rose 4 km above the crater rim and ejecting material 300-500 m from the crater. Ashfall was reported in the cities of Kagoshima (3 km NW), Hioki (25 km WNW), and Ichikikushikino (40 km NW).
Nighttime crater incandescence was noted on 2 and 5 May. An event at 1213 on 5 May at Minamidake summit crater produced a plume that rose 500 m above the crater rim. The Alert Level remained at 3 (on a 5-level scale).
