Emissions from Anatahan |
| Description |
On March 17, 2007, the Anatahan Volcano, in the Northern Mariana Islands, released a plume of ash and/or steam. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] flying onboard the Aqua [ http://aqua.nasa.gov ] satellite captured this image on March 18, 2007, as the volcano's emissions continued. In this image, the volcanic plume pushes toward the southeast then changes direction slightly and aims for the islands of Saipan and Tinian. The volcanic plume is a little darker and more diffuse in shape than the nearby opaque white clouds. Volcanic emissions of sulfur dioxide sometimes react with water and sunlight to create vog—a haze that hangs over the region. Previous eruptions of Anatahan have created substantial vog. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12832 ] Although the chemical composition of the plume cannot be identified from a single picture, south of Saipan and Tinian, the plume takes on an extra-hazy appearance consistent with volcanic fog. The same day MODIS acquired this image, the U.S. Air Force Weather Agency reported an odor of sulfur (which would also suggest the presence of vog) on Guam, approximately 200 kilometers southwest of Saipan.Anatahan [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0804-20= ] is a stratovolcano composed of alternating layers of hardened lava, ash, and rock. Its first recorded eruption [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=15288 ] occurred in May 2003.

Eruption of Anatahan |
| Description |
A major eruption blasted from Anatahan volcano on April 6, 2005, sending a plume of ash up to 15,200 meters (50,000 feet) into the air. This is the largest eruption at the volcano since its first recorded eruption on May 10, 2003. This Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) was acquired by NASA's Terra [ http://terra.nasa.gov/ ] satellite at 00:35 UTC, about eight hours after the eruption began. By this time, the ash plume had spread south to entirely cover Saipan and Tinian, the islands immediately south of the volcano. Anatahan is an uninhabited island, and there have been no injuries reported from either Saipan or Tinian, the inhabited islands that have been affected. Aircraft have been warned to avoid the area because volcanic ash can destroy jet engines. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

| Description |
MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Anatahan ]., A week after its largest eruption in recorded history, the Anatahan volcano is still steaming. A plume of ash and steam rises from the volcano in this series of Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) images, acquired between April 7 and April 13, 2005, by NASA's Terra [ http://terra.nasa.gov/ ] and Aqua [ http://aqua.nasa.gov/ ] satellites. On April 6, the volcano erupted explosively, sending approximately 50 million cubic meters of ash up to 15,240 maters (50,000 feet) into the air. As of April 12, the ash plume had spread over 2,200 kilometers (1,200 nautical miles) west of the volcano to the Philippine Sea. The large eruption also impacted the ocean, as this series of images shows. Starting on April 7, the ocean to the north of the volcano had turned green. Two days later, the circular discoloration had expanded to a ring of green on the north and west sides of the volcano. By April 11, the ring of green water took on a brown shade and expanded even further. On April 13, the discolored water was dark brown, only faintly visible against the black ocean water. The band of discolored water forms a long oval that radiates away from the island to the north and the south, nearly reaching Saipan in the south. A second faint brown-green band of water rings Anatahan. There are several possible explanations for the discolored ocean water, says Frank Trusdell, a geologist with the U.S. Geological Survey at the Hawaiian Volcano Observatory. Trusdell has been monitoring Anatahan's eruption in collaboration with geologists from Saipan. First, ash may have settled in the water near the volcano. Light-colored ash floating near the surface of the ocean would reflect light, giving the water the green tint seen here. The ash would have thinned as it drifted away from the island, reflecting less and less light as it did so. This would account for the darkening color on later days. A second possible explanation is that phytoplankton are feasting on the iron-rich ash that has settled in the water. After Anatahan's first recorded eruption in May 2003, the ocean sprang to life around the volcano. The newly-fallen ash served as fertilizer for tiny ocean plants, called phytoplankton, that grow near the ocean's surface. Dense phytoplankton blooms give the ocean a green tint in satellite imagery. When the blooms die, they fade to brown and disappear as the plants sink into the ocean. There are other, far less plausible explanations for the discoloration seen in these images, says Trusdell, but it's impossible to pinpoint the cause without information from the ground. A week after the eruption, the area around the volcano remains sealed off as Anatahan continues to let off steam, reminding its observers that it's not finished yet.

Eruption of Anatahan |
| Description |
Ash rained down on Saipan, the main island in the chain of islands that make up the Northern Mariana Islands, and its neighbor Tinian on April 6, 2005. The sky over the islands darkened when the Anatahan volcano exploded late on April 5, and nearly 12 hours later, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image, the islands were still completely obscured by a brown cloud of ash. No one was injured in the eruption, but residents have been warned to remain indoors and avoid drinking ash-contaminated water. The fourteen islands of the Northern Mariana Islands, including Anatahan, form a U.S. territory. Sitting 320 kilometers south of the volcano, Guam (a separately administered U.S. Territory) does not appear to have been affected by the ash. The Anatahan volcano itself is actually two volcanoes with overlapping summit calderas. The volcano forms the tiny island of Anatahan, which measures 9 kilometers long by 3 kilometers wide. The larger of the two peaks rises 788 meters from the surface of the sea, while the smaller peak is just 68 meters above sea level. The volcano's first recorded eruption was in May 2003. The April 5 eruption is the largest the volcano has produced since May 2003. NASA image courtesy Liam Gumley, University of Wisconsin-Madison, made from data provided by NOAA/NESDIS. |

Eruption of Anatahan |
| Description |
Continuing eruptions from the Anatahan Volcano in the Mariana Islands have affected local air travel in late July 2005. The volcano's ongoing ash emissions have reduced visibility in the area, forcing nearby Saipan International Airport to suspend departing flights, according to the Pacific Daily News. The U.S. Air Force Weather Agency has likewise reported that the residents of Saipan and Tinian in the Mariana Islands are enduring a strong sulfur odor from the volcano's emissions. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on July 29, 2005. In this image, volcanic ash streams from the Anatahan Volcano toward the southwest as clouds drift overhead. The lighter area to the right of the volcano is caused by sunglint, when the ocean's surface reflects sunlight into the satellite sensor.

Eruption of Anatahan |
| Description |
As reported by the Saipan Tribune Website, the Anatan Volcano spewed volcanic ash to an altitude of nearly 13,000 meters (42,000 feet) in early August, prompting officials to issue a volcanic ash advisory for Saipan and Tinian in the Northern Mariana Islands. The volcano has emitted something besides ash: sulfur dioxide. Sulfur dioxide is colorless, so its presence must be monitored with sensors specially designed to find it. The Ozone Monitoring Instrument (OMI) on NASA's Aura [ http://aura.gsfc.nasa.gov/index.html ] satellite collects data on atmospheric chemistry. OMI monitors sulfur dioxide emissions from Anatahan, and collected data shown in these images between July 25 and 31 (top), and August 2 and 8 (bottom). Highest concentrations appear in red, and lowest concentrations appear in pale pink. In each image, the arrow indicates the volcano's summit. OMI measures sulfur dioxide in terms of molecules per square centimeter of atmosphere, known as Dobson Units. A single Dobson Unit equals 0.0285 grams of sulfur dioxide per square meter of vertical column of atmosphere. The images show different dispersion patters for sulfur dioxide in late July and early August. Between July 25 and 31, predominantly easterly winds carried the noxious emissions away from the populated islands. Between August 2 and 8, however, changing winds allowed sulfur dioxide to accumulate over the Southern Mariana Islands and Guam. Although invisible to human eyes, sulfur dioxide can still make its presence known—by irritating them. Sulfur dioxide can inflame mucous membranes of the eyes, nose, and throat, and even skin. The upper respiratory tract is the most susceptible to sulfur dioxide irritation. Sulfur dioxide also leads to acid rain and volcanic smog (vog) that interferes with air transport. The OMI instrument is a Dutch-Finnish Instrument, provided to the EOS/Aura mission by The Netherlands and Finland. NIVR (the Dutch space agency) is the overall program manager, in coordination with FMI (the Finnish Meteorological Institute). The Royal Netherlands Meteorological Institute (KNMI) is the Principal Investigator institute.

| Description |
Super Typhoon Nabi was a Category 3 typhoon in the western Pacific when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on September 2, 2005, at 11:55 a.m. Tokyo time. It had sustained winds of around 200 kilometers an hour (160 miles per hour) and was located roughly 1,000 kilometers (600 miles) from Saipan and Okinawa at that time. It was predicted to gather strength and make landfall at the southern end of the Korean peninsula early on September 7. However, the range of possible storm tracks as of September 2 takes in possibilities ranging from Shanghai on Asian mainland to Kyoto on the southern end of the Japanese Islands.

The lower photograph shows how Anatahan looked from the Space Shuttle in 1996 (photo STS080-708-28) On the night of May 10, the Anatahan Volcano announced itself with a vigorous eruption that sent high-level ash over a wide area. About 12 hours later, on May 11 at 00:19 GMT, the crew of the International Space Station observed and photographed this ash plume, describing it as huge. By May 15 a state of emergency had been declared in the Northern Mariana Islands as the eruption appeared to be intensifying.

Typhoon Longwang |
| Description |
Typhoon Longwang was a small but well-organized and powerful storm system when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 12:50 p.m. local time, on September 27, 2005. At the time of this MODIS observation, Longwang was 1,000 kilometers (600 miles) from Saipan in the Northern Mariana Islands, and well away from any significant land mass. It was travelling roughly westward towards the Chinese coast on a track that would take it through the southern fringe of the Japanese islands. Typhoon Longwang had sustained winds of 180 kilometers per hour (115 miles per hour) near the storm's center, and it was projected to become significantly stronger in the following days.

Typhoon Tingting

Typhoon Tingting |
| Description |
Tingting, at the time still a tropical storm, dumped record breaking rains on Guam over the weekend resulting in extensive flooding and mudslides. The weather service reported that 16 inches of rain fell on Sunday alone (local time). The tropical depression that would later become Tingting first formed on the 25th of June 2004 several hundred miles east-southeast of the southern Mariana Islands. The storm proceeded westward for a short time before turning northwest. The system slowly strengthened becoming a tropical storm on the 26th and a minimal typhoon on the 28th as it passed north of Saipan in the central Marianas. After passing through the island chain, the storm turned northward and is expected to pass close to Iwo Jima. The Tropical Rainfall Measuring Mission (TRMM) satellite has been monitoring rainfall over the global tropics since its launch in November of 1997. Armed with its array of both passive and active sensors, TRMM has been able to image numerous tropical cyclones providing a unique perspective on their structures. Such is the case with Tingting as shown by the following images. The first image was taken at 4:28 UTC on 28 June 2004 just as Tingting was passing through the central Mariana Islands. It shows the horizontal distribution of rain intensity. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), the first and only precipitation radar in space, and rain rates in the outer swath are from the TRMM Microwave Imager (TMI). These rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). This image shows that Tingting has a well-defined center of circulation as evidenced by the spiraling rainbands to the northeast (blue arches). However, the majority of the rainfall is contained in a large rainband well to the southwest of the center. This rainband contains areas of heavy (red), moderate (green) and light rain (blue). At the time of this image, Tingting was classified as a minimal typhoon by the Joint Typhoon Warning Center with winds estimated at 65 knots (75 mph). The second image was taken at 11:43 UTC on the 29th and reveals that the storm had become better organized with a more pronounced eye and a more symmetrical rainfield. However, rain intensities around the eye are rather light (blue areas). As tropical cyclones rely on condensational heating near their cores to maintain their circulations, the weak rain rates near the storm's center as revealed by TRMM means that Tingting is not likely to strengthen. Tingting was estimated to have sustained winds of 80 knots (92 mph) at the time of this image. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center provides quantitative rainfall estimates over the global tropics. The final two images show MPA rainfall totals for the period 25-28 June 2004 around Guam as a result of Tingting. The dark red area over Guam indicates rainfall on the order of 16 to 20, inches which is in excellent agreement with the reported values on the ground. The final image shows contoured values in mm. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

The tropical depression that would later become Tingting first formed on the 25th of June 2004 several hundred miles east-southeast of the southern Mariana Islands. The storm proceeded westward for a short time before turning northwest. The system slowly strengthened becoming a tropical storm on the 26th and a minimal typhoon on the 28th as it passed north of Saipan in the central Marianas. After passing through the island chain, the storm turned northward and is expected to pass close to Iwo Jima. The Tropical Rainfall Measuring Mission (TRMM) satellite has been monitoring rainfall over the global tropics since its launch in November of 1997. Armed with its array of both passive and active sensors, TRMM has been able to image numerous tropical cyclones providing a unique perspective on their structures. Such is the case with Tingting as shown by the following images. The first image was taken at 4:28 UTC on 28 June 2004 just as Tingting was passing through the central Mariana Islands. It shows the horizontal distribution of rain intensity. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), the first and only precipitation radar in space, and rain rates in the outer swath are from the TRMM Microwave Imager (TMI). These rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). This image shows that Tingting has a well-defined center of circulation as evidenced by the spiraling rainbands to the northeast (blue arches). However, the majority of the rainfall is contained in a large rainband well to the southwest of the center. This rainband contains areas of heavy (red), moderate (green) and light rain (blue). At the time of this image, Tingting was classified as a minimal typhoon by the Joint Typhoon Warning Center with winds estimated at 65 knots (75 mph). The second image was taken at 11:43 UTC on the 29th and reveals that the storm had become better organized with a more pronounced eye and a more symmetrical rainfield. However, rain intensities around the eye are rather light (blue areas). As tropical cyclones rely on condensational heating near their cores to maintain their circulations, the weak rain rates near the storm's center as revealed by TRMM means that Tingting is not likely to strengthen. Tingting was estimated to have sustained winds of 80 knots (92 mph) at the time of this image. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center provides quantitative rainfall estimates over the global tropics. The final two images show MPA rainfall totals for the period 25-28 June 2004 around Guam as a result of Tingting. The dark red area over Guam indicates rainfall on the order of 16 to 20, inches which is in excellent agreement with the reported values on the ground. The final image shows contoured values in mm. TRMM is a joint mission between NASA and the Japanese space agency JAXA.
