04/1976 (SEAN 01:07) Explosion sends column 3 km high

An explosion at Shin-dake cone yielded columns of smoke 3,000 m high at about [1540] on 2 April. After 30 minutes the height of the smoke column decreased to about 200 m (twice that of usual emissions). Egg-sized volcanic ejecta fell, and ash 2 cm deep was measured in a village 3 km from the crater. The last explosion took place on 3 June 1974. [JMA reported that there was no damage.]

09/1980 (SEAN 05:09) Weak ash emission

After four years of quiet, a brief, weak explosion produced a [2-3-km-high] ash cloud on 28 September at 0510. Ash fell on the sea [SW] of the volcano, missing the homes of the 12 x 5 km island's 300 residents. Activity after the explosion was limited to emission of white vapor through the end of September. Minor ash explosions have occurred in seven different years since 1966.

12/1980 (SEAN 05:12) Seismicity and steaming decline; 28 September eruption fissure and tephra described

"After the 28 September eruption, which lasted for 1/2 hour, no additional eruptions had occurred as of the end of December. Eight scientists from Kyoto University, Kagoshima University, and the JMA observatory arrived at the island on 1 October, installing portable seismometers at five sites. The next day, they climbed to the new fissure, which was 0.6-6.0 m wide and 750 m long, trending N-S near Shin-dake crater (figure 1), active in historic time. A considerable amount of white vapor was emitted from the fissure.

"The SW sector of the volcano was covered with gray ash, l m thick near the fissure and 2 cm thick at the base of the volcano, on the coast. Blocks were scattered N and W of the fissure, the largest block measuring about 2 m in diameter. No essential ejecta were observed. The volume of ejecta was estimated at about 105 m3. Steaming decreased gradually during October, and was restricted to 10 small craters on the fissure by mid-October.

"Seismicity was relatively weak in October and November except on 4 and 9 October when swarms of small B-type earthquakes were recorded (figure 2). The JMA's seismometer was removed on 15 November because the volcano was quiet. People on the island reported no felt earthquakes, and decreasing steam activity through December. Life returned to normal for the island's 300 inhabitants soon after the 28 September eruption."

03/1996 (BGVN 21:03) Increasing number of earthquakes since January

According to the Sakura-jima Volcanological Observatory of Kyoto University, the number of earthquakes has increased around Shin-dake since January. The total number of earthquakes recorded was 32 in January, 40 in February, and 77 in March.

A group of young stratovolcanoes forms the E end of Kuchinoerabu-jima Island, midway between Suwanose-jima and Kyushu. Several villages on the 4 x 12 km island are located within a few kilometers of the active crater of Shin-dake and have suffered damage from historical eruptions. Shin-dake is the summit cone, and has been the site of all 13 eruptions known since 1840. The last eruption was a weak 30-minute explosion on 28 September 1980 that sent an ash plume 2-3 km high.

08/1999 (BGVN 24:08) Increased seismicity, but no change at the fumaroles

The Japan Meteorological Agency (JMA) reported an increase in seismic activity on Kuchinoerabu-jima since July 1999 based on data from Sakura-jima Volcano Observatory (SVO), Kyoto University. The number of earthquakes/month increased, rising from 26 in June, to 87 in July, and to 195 in August. By mid-September, JMA and SVO had not observed any anomalous change in fumaroles in the craters of Shin-dake (the youngest volcanic cone).

Kuchinoerabu-jima is a volcanic island 12 km long and 5 km wide located ~100 km SSW of southern Kyushu Island and Sakura-jima volcano. An andesite stratovolcano, Kuchinoerabu-jima includes both an older edifice to the NW and young edifices (Furudake and Shindake cones) to the SE. Historical eruptions at Shindake were phreatic. An eruption in December 1933 killed 8 persons and injured 26.

09/2008 (BGVN 33:09) A rise in hazard status owing to 2008 seismicity and GPS-measured inflation

Anomalous seismicity and inflation was noted at Kuchinoerabu-jima in late 2008. Seismic unrest was also reported during mid-1999 (BGVN 24:08). The island of the same name is home to ~ 140 residents and lies ~ 130 km S of the city of Kagoshima (Kyushu Island, Japan). The 19-km-diameter Kikai caldera, which is mainly submarine, sits a few tens of kilometers to the N, and is renowned for its massive eruption ~ 6,300 years ago. Kuchinoerabu Island contains a composite elongate cone made up of three closely spaced Holocene volcanoes supporting the island's S-central zone (figure 3; Geshi and Nakano, 2007; Geshi and Kobayashi, 2007).

Increased seismicity prompted the Japan Meteorological Agency (JMA) to raise the Alert Level from 1 to 2 (on a scale of 1-5) on 4 September 2008, and to level 3 on 27 October 2008. According to JMA, GPS measurements indicated inflation just below the summit crater that had started in September was continuing in October. Fumarolic activity near the summit had also increased.

11/2010 (BGVN 35:11) Some periods of increased seismicity through 2009; white plumes

No eruptive activity has been reported at Kuchinoerabu-jima since a small eruption in September 1980 (SEAN 05:12). However, there have been many periods of elevated seismicity.

One such episode, beginning in early September 2008, prompted two increases in the hazard status by late October when the seismicity was accompanied by inflation and increased fumarolic activity near the summit (BGVN 33:09). The Alert Level remained at 3 (on a scale of 1-5) until 18 March 2009, when it was decreased to level 2. Sulfur dioxide emissions had decreased in January 2009, followed by a decrease in the rate of deformation.

Seismicity data during 2003-2009. Seismic data recorded by JMA between January 2003 and December 2006 indicted that the number of monthly volcanic earthquakes was typically below 200, with less than 30 tremor events. Seismicity was higher in March 2004, January-February, May, July-September, and November 2005, March-April, August, and October-December 2006, and February and April 2007 (table 1).

A seismic swarm consisting of 70 events on 4 September 2008 resulted in the Alert Level increase already reported. The months of September-December 2008 included high numbers of tremor episodes (table 1). Large numbers of tremors were recorded again in April-May 2009. Seismicity decreased after that time, until an earthquake swarm was recorded during 27-29 September 2009 (about 150 earthquakes). Tremor events also increased briefly, with 38 between 28 September and 6 October 2009. White fumarolic plumes rising from the summit area increased in height (up to 400 m) and frequency (every 1-2 days) after September 2008 through 2009.

01/2013 (BGVN 38:01) Increased seismicity, 11 December 2011-5 January 2012

Since a small eruption in 1980, Kuchinoerabu-jima experienced numerous periods of elevated seismicity, with volcanic earthquakes and tremor detected at least through December 2009 (BGVN 35:11). The volcano is located in the Ryukyu Island arc, off Japan’s SW coast (figure 4).

Recent monthly reports of volcanic activity from the Japan Meteorological Agency (JMA) translated into English resumed in October 2010. The only recent English-translated JMA report on Kuchinoerabu-jima available online through December 2012 was in January 2012. We know of no other recent report on this volcano’s seismic activity; therefore, this report summarizes seismicity between December 2011 and January 2012.

According to JMA, seismicity increased to a relatively high level immediately after 11 December 2011, but then decreased on 5 January 2012. On 20 January 2012, the Alert Level was lowered from 2 to 1; JMA noted that the possibility of an eruption was minimal.

During the December 2011-January 2012 period, no significant change in plume activity was observed, and plume heights remained below 100 m above the crater. According to a field survey on 11 January, infrared images (compared to images obtained in December 2011) showed no significant change in temperature distribution either at the summit or on the W slope of Shin-dake (also refered to as Shin-take), the youngest and most active cone.

Field surveys found that sulfur dioxide levels were 50 and 100 metric tons/day on 12 and 13 January 2012, respectively, which were lower than those recorded in December 2011 (200 metric tons/day on 9 December 2011).

According to JMA, continuous GPS measurements have established a baseline across Shin-dake, collecting data since September 2010. Shin-dake’s rate of change in surface deformation at the stations has been slowing since September 2011.

A group of young stratovolcanoes forms the eastern end of the irregularly shaped island of Kuchinoerabujima in the northern Ryukyus, 15 km west of Yakushima. Furutake, Shintake, and Noike were erupted from south to north, respectively, to form a composite cone that is parallel to the trend of the Ryukyu Islands. The highest peak, Furutake, reaches only 657 m above sea level. The youngest cone, 640-m-high Shintake, was formed after the NW side of Furutake was breached by an explosion. All historical eruptions have occurred from Shintake, although a lava flow from the S flank of Furutake that reached the coast has a very fresh morphology. Frequent explosive eruptions have taken place from Shintake since 1840; the largest of these was in December 1933. Several villages on the 4 x 12 km island are located within a few kilometers of the active crater and have suffered damage from eruptions.

Steam plumes pour from a newly opened arcuate fissure on Shin-dake, the summit crater of Japan's Kuchinoerabu volcano, on September 29, 1980. A brief eruption from the new 800-m-long fissure the day before ejected blocks and ash up to 2 km above the crater. A group of young stratovolcanoes forms the eastern end of the island of Kuchinoerabu-jima in the Ryukyu Islands. All historical eruptions have occurred from Shin-dake, which has had frequent explosive eruptions since 1840 that have sometimes damaged villages located near the crater.

Kuchinoerabu volcano rises to the SE above the fishing village of Motomura. The active cone of Shin-dake is in the center, Sankakuten-yama at the left, and Furu-dake (Huru-dake), the 649 m high point of the island, at the right. Shin-dake was formed after the NW side of Furu-dake was breached by an explosion and has been the site of frequent explosive eruptions in historical time. Several villages on the 4 x 12 km island are located within a few kilometers of Shin-dake and have suffered damage from eruptions.
