Ambrym Volcano (Vanuatu)
16.25 S, 168.12 E, summit elevation 1334 m, Pyroclastic Shield Volcano
Friday 25th February 2005
West Ambrym has been declared a disaster area following eruptions and acid rain which has caused damage to food gardens. The community needs new crop plants and food aid to assist through the next 4 months of the declared disaster period. There needs to be a continued awareness programme on the volcanic hazard and risk, and measures to reduce the effects of the eruption. The government of Vanuatu is looking at a resettlement programme for the people displaced by the eruption. Reports from the island indicate that food crops have been destroyed by the ongoing eruptions and acid rainfall. Satellite images show continued hotspot activity at the volcano, indicating the proximity of magma to the surface. The volcano has been closed to the public until further notice due to volcanic activity. Report by John Seach.

Kliuchevskoi Volcano (Russia)
56.06 N, 160.64 E, summit elevation 4835 m, stratovolcano
Monday 21st February 2005
Lava has flowed down the slope of Kliuchevskoi volcano, melting a large section of the Ehrman glacier. A 2.5 km lava flow moved down the north east slope. The Ehrman glacier reaches a depth of 300 meters in some places. Mud flows may rush down the volcano's slopes, now that the ice is melting. Ash emissions from Kliuchevskoi volcano, as well asf from neighboring Shiveluch volcano, may threaten aircraft. Kliuchevskoi, which is the highest Eurasian volcano, began to erupt January 17. A bright lava glow can be seen above the crater at night. Volcanic bombs are being ejected 300 to 500 meters above the crater.

Kilauea Volcano (Hawaii)
19.425 N, 155.292 W, summit elevation 1222 m, Shield volcano
Saturday 19th February 2005
Lava continues to flow into the sea at Kilauea volcano in Hawaii. The west branch of PKK lava flow is reaching the sea at West Highcastle lava delta. The West Highcastle ocean entry is about 1.6 miles from the end of Chain of Craters Road, drawing a daily crowd of approximately 1,500. During the peak sunset viewing period, more than 150 cars are parked along the road. The second ocean entry is at Ka`ili`ili, about 1 km west of Waha`ula, which is about five miles from the end of the road. The West Highcastle lava flow was the most active on Friday. Some hazards for lava watchers are high temperatures in the high 80s (F) and low 90s, toxic fumes, unstable ground and the potential for the collapse of newly created coastline. The source of the lava flows is Pu'u 'O'o crater, which is in an inaccessible area of the mountain. Pu'u 'O'o crater has been splattering lava into the air over the past few days from five vents. On February 10 there was a lava flow inside the crater from East Pond vent. This is the first intra crater lava flow at Pu'u 'O'o for 6 months. Kilauea has been erupting continuously since Jan. 3, 1983.

Manam Volcano (Papua New Guinea)
4.10 S, 145.06 E, summit elevation 1807 m, Stratovolcano
Thursday 10th February 2005
Situation report update. The large eruption of 28th January caused one death, and trapped 2000 people on the island. Evacuation of the remaining residents from Manam is almost complete, with only 167 people remaining on the island. The future of the evacuees on the mainland remains uncertain. There is some disagreement about the land ownership on the mainland and this is having some affect on the relief effort. The Papua New Guinea army is assisting with security. The number of people in care centres is 7875. The location of the evacuees are: Potsdam 3068, Asarumba 1448, Mangem 755, Dagui 426, Tobenham 1028, Bonaputa 425, Bogia 725, Suaru 843. The Madang provincial authorities have launched an appeal to raise more funds to assist the evacuees. Residents of the care centres have suffered from a number of health problems including 523 cases of malaria and 99 people with pneumonia. People continue to sleep under tarpaulins, and these have been damaged by severe weather and 2 cm of ashfall from the volcano. More tarpaulins have been requested to replace those damaged by the recent eruption. The immediate relief effort aims to replace tarpaulins, provide water containers and purification tablets, distribute soap, advise residents to boil drinking water, and conduct community based health awareness activities. Eruptions continue at Manam volcano which remains at stage 3 alert (out of 4). Further large eruptions are possible.

Lopevi Volcano (Vanuatu)
16.50 S, 168.34 E, summit elevation 1413 m, Stratovolcano
Thursday 10th February 2005
Satellite images indicate possible eruptive activity at Lopevi Volcano in Vanuatu beginning at the end of January 2005 and continuing in February. Lopevi volcano is an uninhabited island in central Vanuatu, SW Pacific. Eruptive activity often goes unreported. The hotspot images indicates that magma is close to the surface, or there has been a small lava flow.
Reports of eruptive activity in 2004. John Seach visited SE Ambrym volcano in November 2004 and received reports from residents about previously unreported eruptions of Lopevi in 2004. During September 2004, five large booming noises were heard coming from Lopevi volcano by villagers in south Ambrym. Explosions were separated by 2 minutes. The next day there was ashfall on N and W Ambrym. The eruption was confirmed by satellite image on 28th September 2004. Hotspot activity was also noted at Lopevi on 13th May 2004 a satellite image. This correlates with eyewitness accounts of an eruption of Lopevi volcano obtained by John Seach during a field trip to the region.

Kliuchevskoi Volcano (Russia)
56.06 N, 160.64 E, summit elevation 4835 m, stratovolcano
Wednesday 9th February 2005
Eruptions continue at Kliuchevskoi volcano in Russia. Ash emissions are visible in satellite images stretching a hundred kilometres from the volcano. Lava is flowing down the western slope of the volcano. Mixing of lava and snow is creating phreatic explosions. Lava fountains and bomb ejection is visible at the summit crater. The eruption is creating mudflows with a diameter of 500 m, and moving boulders 3 m in diameter, and tree trunks. The mudflows pose a serious risk, and residents have been warned about the hazard. Flights near the volcano have not been affected. Kliuchevskoi volcano began erupting on 17th January and the eruptions may continue for months to years.

Ambrym Volcano (Vanuatu)
16.25 S, 168.12 E, summit elevation 1334 m, Pyroclastic Shield Volcano
Monday 7th February 2005
Continued eruptions from Ambrym Volcano are causing problems for residents of the island. Acid rain and ashfall have forced several families to relocate to the islands of Malekula and Santo. Serious food and water shortage has been a problem on the island which was hit by cyclone Ivy early 2004 and then suffered volcanic eruptions over the year. John Seach visited Ambrym in October and November 2004 and documented the volcanic eruptions and damage to the island. A total loss of food crops was observed in south and west Ambrym. This was caused by northerly winds and rain which blew during large ash emissions from one of the summit craters. John Seach measured caldera rainfall with a pH of 2.0, five kilometres from the active craters. Extensive yellowing was seen on vegetation and crops 12 km from the craters on the populated coastal areas. This type of volcanic damage has continued into 2005. Staple foods like banana, kumala, island cabbage and coconut have been destroyed. The western side of the island is the worst affected. Some people have complained of stomach aches and diarrhoea. So far no relief assistance has been sent. Ambrym is one of the most active volcanoes in the Melanesia. It has been in a regular state of eruption since first reports by Cook in 1774. The volcano is noted for the lava lake which regularly appear in the summit craters. The lava lakes are currently not present at the volcano.

Philippines Earthquake (Magnitude 7.1)
Sunday 6th February 2005
A major earthquake hit the Philippines on Saturday, February 05, 2005 at 08:23 PM local time. The earthquake was deep, at 486 km, and there are no reports of damage. The epicenter was located in the Celebes Sea, 215 km SE of Zamboanga, Mindanao, Philippines. Deep focus earthquakes are not as dangerous as shallow ones, and this event is not expected to cause a tsunami or result in large aftershocks. The Philippines contain a number of active volcanoes, including Mt Pinatubo, which in 1991 was the site of the second largest eruption of the 20th century. The earthquake was not located near Mt Pinatubo.

Kilauea Volcano (Hawaii)
19.425 N, 155.292 W, summit elevation 1222 m, Shield volcano
Friday 4th February 2005
Lava has reached the ocean at two locations at Kilauea Volcano in Hawaii. One entry point is about 1.5 miles from the parking area at the end of Chain of Craters Road, and the second is about 4.5 miles from the road. The flow is near an area known as West Highcastle and began trickling into the ocean late last week but the volcano is now erupting significant quantities of lava. The flow in an area called Ka'ili'ili began entering the ocean Monday. Both flows originate from a vent on the southwest flank of Pu'u 'O'o. About 1,000 people a day have been making the trip down Chain of Craters Road to watch the lava. The numbers of people are expected to pick up as word spreads that lava has reached the sea again.

Mayon Volcano (Philippines)
13.257 N, 123.685 E, summit elevation 2462 m, stratovolcano
Thursday 3rd February 2005
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported today that increased seismic activity at Mayon Volcano in central Philippines has been recorded during the past 24 hours. Six low frequency and one high frequency short duration harmonic tremors were registered by seismometers located at the volcano. The agency warned residents living near the volcano not to venture into the six-kilometer radius Permanent Danger Zone. The exclusion zone is strictly enforced on the southeast sector where debris avalanches and pyroclastic flows are liable to occur. The last large eruptions of Mayon were in July 2001when there were pyroclastic flows, lava fountains and lahars.

Guam Hit by Earthquake and Volcanic Haze
Tuesday 1st February 2005
Residents of Guam in the Mariana Islands are suffering from sickness from volcanic haze due to the eruption of Anatahan Volcano. Dozens of people have arrived at Guam's only hospital complaining of respiratory problems and headaches. Aerosol particles from the volcanic haze may cause headaches, respiratory ailments, watery eyes, sore throat and flu-like symptoms. Residents should expect hazy conditions for the next few days because of ash being blown by the wind from the continuously erupting Anatahan volcano. Anatahan Island has been placed off limits until further notice and aircraft are advised to pass upwind of Anatahan or beyond 30 km downwind from the island and exercise due caution within 30 km of Anatahan.
A large earthquake of magnitude 6.2 has hit Guam. The earthquake hit at Wednesday, 2nd February, 2005 at 12:30:25 PM local time. The epicentre was located 70 km north of Hagatna, Guam.

Kliuchevskoi Volcano (Russia)
56.06 N, 160.64 E, summit elevation 4835 m, stratovolcano
Tuesday 1st February 2005
Mudflows have rushed down the slopes of Kliuchevskoi volcano in Russia. The mud flowed down Krutenkaya River and carried stones up to three meters in diameter, and reached the Kamchatka river six to seven km from Klyuchi town. The mudflow travelled along a road east of Klyuchi, sweeping away trees that had been felled by lumberjacks. The mudflow was triggered by volcanic bombs or lava flow from the eruption of Kliuchevskoi volcano. Volcanic bombs have been expelled with sizes of up to 15 m in diameter. A strong glow can be seen above the volcano's crater at night even in bad weather.

Kliuchevskoi Volcano (Russia)
56.06 N, 160.64 E, summit elevation 4835 m, stratovolcano
Tuesday 1st February 2005
Kliuchevskoi Volcano is ejecting steam and steam up to 1 km above the crater. The plume has stretched out at more than 100 km in the northwestern direction. Seismic stations near the volcano have registered high-frequency vibration. Scientists think that the vibration was accompanied by a discharge of ash or a lava stream. It is believed that the summit crater, which is about 700 m in diameter, is being filled with lava. The magnitude of the eruption that began on January 17 has been growing. Summit crater eruptions normally last from a month to several years, posing a serious threat to domestic and international air services.
