Fumarole temperatures increase

"Fumarolic activity persisted at Ahuan vent on the SW flank. When temperatures were measured at Ahuan vent on 29 November, the hottest fumarole was 473°C, 70° higher than in April 1983, when Dartmouth scientists last measured temperatures at Parícutin. Several fumaroles over an area of about 50 m2 were hotter than 300°C. No physical changes in the area were apparent since April 1983."

Fumarole temperatures decline

Geologists mapped fumaroles and measured temperatures on 8 and 16 May. As in previous years, fumaroles were hottest at Ahuan vent (figure 1) but had cooled to 336°C, from 473° in November 1985 and 375° in November 1986. The area seemed morphologically unchanged since April 1983. Fumaroles at Sapichu vent ranged from 186° to 275°C, an increase of as much as 120° since they were last measured in April 1983. Sulfur continued to be deposited around the Sapichu fumaroles. All other fumaroles at Parícutin had temperatures of

This photo shows an ash plume rising above Parícutin on 9 June 1943, seen here from the Uruapan highway to the east. Prevailing winds distribute the ash plume to the south. Other scoria cones appear on the horizon, some of the 1,000-plus scoria cones within the massive Michoacán-Guanajuato volcanic field.

The tower of the unfinished San Juan Parangaricutiro church rises above the lava flows that surrounded it in 1944. The Taquí lava flow began on 8 January 1944 from the SW base of Parícutin. Renewed lava extrusion on 24 April threatened the town of San Juan Parangaricutiro and impacted it 17 June. The church was surrounded by lava in July. By the time the flow ceased in early August it had a length of 10 km.

Parícutin, the volcano that erupted in cornfield in 1943, is the best-known feature of the Michoacán-Guanajuato volcanic field. The huge field contains over 1,400 vents covering a wide area of Michoacán and Guanajuato states. Scoria cones are the predominant volcanic form, and lava domes, maars, tuff rings, and lava flows are also present. Parícutin is seen here from the NE with Cerro de Tancítaro in the background.

Photo by James Allan, 1985 (Smithsonian Institution).
The flat-topped Hoya el Huanillo cinder cone, located about 35 km NE of Parícutin, erupted during the early Holocene about 9300 years ago. It is seen here from the NW with the town of Cherán in the left distance near the Cerro Cucundicata cinder cone. In contrast to many other Michoacán cinder cones, only a small ash-covered lava flow was emitted from Hoya el Huanillo.

Parícutin cinder cone, born in a Mexican cornfield in 1943, is perhaps the world's best-known example of a pyroclastic cone. Pyroclastic cones (from the Greek words for "fire" and "broken") are created by the accumulation of explosively ejected fragmental material around a volcanic vent. Depending on the dominant type of ejecta, they are called cinder cones, scoria cones, pumice cones, ash cones, or tuff cones. Pyroclastic cones are typically tens of meters to several hundred meters high and often issue lava flows from vents at their base.

An aerial view from the NNW on 5 March 1943, about two weeks after the start of the Parícutin eruption, shows the Quitzocho lava flow advancing to the NE as an ash plume rises from the scoria cone. The flow was about 6-15 m thick as it advanced.

An ash plume rises above the new Parícutin cone on 21 February 1943, the second day of the eruption. The new cone is about 30 m high and is just rising above the treetops in this view from the NE. During this early stage the cone had slope angles of 32 degrees toward the west and lower angles to the east. At this point lava had begun flowing to the east.

An incandescent lava flow travels down a channel within solidified lava near the SW-flank vents of Parícutin in 1945. Lava flows at this time traveled NW over the site of the village of Parícutin. The Taquí lava flows erupted during 1944-45 and covered about 18 km2. The most striking feature of the Taquí flows was the development of hornitos (rootless vents) when molten lava was ejected through overlying solidified crust.

An ash plume rises from Parícutin in October 1944. The photo was taken from the north at the outskirts of the town of San Juan Parangaricutiro. Lava flows in the foreground had already buried the town; the church tower seen in many other photos of the Parícutin eruption is hidden behind the small tree to the right.

An ash plume at Parícutin in 1944 is photographed from the first observatory cabin 1.5 km north, with local resident Celedonio Gutierrez in the foreground. Gutierrez was born in the nearby town of San Juan Parangaricutiro, which was inundated by lava flows, and became actively involved in collaborations with U.S. scientists throughout the eruption.

The first lava flow from Parícutin, the Quitzocho flow, moves northward over cornfields prepared for planting. An ash plume rises from the new cone, which by the time of this photo on 25 February, the 5th day of the eruption, was already more than 150 m high. Gas plumes rise from the advancing lava flow.

The steeple of the church of San Juan Parangaricutiro rises above surrounding lava fields in the center of the photo, seen here from the NE. The still-unfinished church was inundated by lava in July 1944, a month after flows began advancing into the town. The unvegetated, steeper-sided lava flows in the background were erupted later during 1944-46.

This nighttime time-exposure of México's Parícutin volcano in 1948 shows a Strombolian eruption ejecting incandescent blocks that then rolled down the slopes of the cone. Parícutin is known as the volcano that erupted in a cornfield in 1943. It grew to a height of more than 150 m within the first week of its appearance and remained active until 1952.

Photo by Carl Fries, 1948 (U.S. Geological Survey).
This sketch by Mexican artist Dr. Atl depicts the early moments of the Parícutin eruption in a cornfield near the village from which the volcano was named. A Tarascan farmer, Dionisio Pulido, observed the formation of the eruptive vent in his field about 1630 on 20 February 1943 as he was burning branches.

In mid-November 1944 lava broke out of the SSW base of the cone, below the south vent in the crater, seen here from the S. The Ahuán flow advanced over the earlier Taquí flows in the foreground. A small lava intrusion was exposed in the flank of the cone a short distance above the vent. Ahuán flows traveled around the east side of the cone and to the north.

A villager inspects the roof of a house in the village of Parícutin that was destroyed by heavy ashfall in the first year of the eruption. The village that the volcano was named after was located only 3 km NW of the new cone. Ashfall was particularly intense during the eruption's second to fifth months, and the town's 733 residents were forced to evacuate four months after the eruption began. The Mexican government provided new lands in Caltzontzín, 27 km to the SE.

A vertical aerial photo of Parícutin taken on 26 May 1945 shows the cone at the bottom with the partially buried horseshoe-shaped Sapichu vent on its NE flank. Lava flows, forming the lighter-colored areas in the photo, surround the Quitzocho Ridge in the center of the photo and the older Cerro de Jarátiro scoria cone at the top. Ultimately nearly the entire Quitzocho Ridge was buried by lava flows.

One of the first photographs taken of the Parícutin eruption shows an ash plume rising from the new volcano at 1800 on 20 February 1943, 1.5 hours after the start of the eruption. The photo was taken near Ticuiro, 5 km NNW of the volcano, with the fields of San Juan Parangaricutiro, later overrun by lava flows, in the foreground. Cerro de Canicjuata is the forested older cone to the right.

A geologist observes an ash plume rising above the crater of Parícutin on 22 March 1944, as seen from 1 km SW at Mesa de Cocjarao. During March 1944 the eruptive activity ranged from small ash plumes accompanied by deep rumbling to large but almost soundless ash plumes, as was true with the plume shown here.

Photo by William Foshag, 1944 (Smithsonian Institution, published in Foshag and Gonzáles-Reyna, 1956).
Villagers observe an ash plume rising above Parícutin in 1944 beyond the streets of San Juan Parangaricutiro, soon to be overrun by lava flows. In June and July 1944 lava advanced slowly through the town, which was incrementally evacuated as the flow progressed. Many residents, showing their deep attachment to the land, stayed until the lava overran the last segments of their property.

Local Tarascan residents observe Parícutin volcano from Cerro de Equijuata, 2.5 km to the NNE, in March 1944. In this photo taken a little more than a year after the eruption began the Sapichu cone appears at the NE (left-hand) base of Parícutin. The rugged lava flows of June 1943 are visible in the middle of the photo. Heavy ashfall has defoliated trees and a thick ash deposit mantles the landscape.

An ash plume rises from the summit crater of Parícutin sometime during 1946-48. A thick ash deposit covers the foreground. An estimated 4,500 cattle and 550 horses died during the heavy ashfall in the early months of the eruption, devastating the local people who depended on the animals for food, plowing, and transportation. Ashfall was deeper than 15 cm over a 300 km2 area around the volcano and continued with varying intensity throughout the 9-year-long eruption.

The Jorullo cone eruption began in 1759 in the Michoacán-Guanajuato Volcanic Field. In this view from the NW the unvegetated area visible on the center-horizon is the final lobe that flowed north. Volcán del Norte, one of Jorullo's four flank cones visible on the left horizon, produced a lava flow towards the west during the middle stages of the 1759-74 eruption.

Photo by Jim Luhr, 1996 (Smithsonian Institution).
The principal vent of Jorullo formed the scoria cone seen here from the SSE that grew to 250 m in height during the first month and a half of the 1759 eruption. Lava flows were erupted at some unknown later time from four flank vents located along a NE-SW fissure cutting through the main cone.

Photo by Jim Luhr, 1996 (Smithsonian Institution).
The most recent lava flows of the 1759-74 Jorullo eruption appear in the left and foreground of this view from the north with the sparsely vegetated cone of Jorullo to the upper right. Unlike earlier lava flows that were covered with ashfall from explosive eruptions, this latest does not and remains relatively unvegetated in this 1982 photo. Lava flows were erupted from NE-SW-trending flank vents and covered an area of 9 km2.

Photo by Jim Luhr, 1982 (Smithsonian Institution).
Jorullo, a predecessor to Parícutin, was the first cinder cone of the Michoacán-Guanajuato volcanic field to be formed in historical time. The eruption began on September 29, 1759. Pyroclastic flows and mudflows in the first days caused much damage to neighboring haciendas. The first incandescent bombs were observed on October 8, and after October 14 the eruption was dominantly magmatic. By November 13 the cone had reached 250 m height. Major eruptions continued until 1764, and lesser eruptions were reported until 1774.

Lava flows in the western part of the Michoacán-Guanajuato volcanic field are seen here from the north. Cerro el Astillero, a scoria cone near the middle right-hand margin of the photo, was the source of the unvegetated lava flow that extends to the east and then south. Cerro el Pedegral, a cone near the lower left, produced lava flows to the west and south toward the upper part of the photo. This lava field is located near the town of Tancítaro and is among the many Holocene flows in the Michoacán-Guanajuato field.

Since the end of the 1759-1774 eruption the Jorullo crater has been collapsing inward along steep, arcuate faults, increasing its dimensions to 400 x 500 m; its depth was 150 m by 1997.

Photo by Jim Luhr, 1997 (Smithsonian Institution).
Jorullo scoria cone of the Michoacán-Guanajuato volcanic field is seen here from the ENE. The eruption began with phreatic and phreatomagmatic activity on 29 September 1759 with wet ashfall and lahars that caused damage to neighboring haciendas. By 13 November the cone had reached 250 m in height, and the eruption episode continued until 1774. The sparsely vegetated lava flow to the right was the produced near the end of the eruption.

Parícutin, the volcano that grew in a cornfield in 1943, is a well-known feature of the Michoacán-Guanajuato volcanic field. The huge field contains over 1,400 vents covering a wide area across the Michoacán and Guanajuato states. Scoria cones are the predominant volcanic landform, and lava domes, maars, tuff rings, and lava flows are also present. Parícutin is seen here from the NE with the Nueva Juatita flank vent in the foreground, the main source of lava during the last five years of the eruption.

Photo by Jim Luhr, 1997 (Smithsonian Institution).
By the end of the 9-year-long eruption of Parícutin, the new scoria cone had risen 424 m above the surface of the original cornfield. The 900-m-wide oval-shaped cone is elongated in a NW-SE direction and is truncated by a circular 280-m-wide crater. The western peak (right) is the highest point on the crater rim. The NE-flank peak of Nuevo Juatita is in the foreground with its top covered by white minerals from fumaroles, and was the main source of lava flows during the last five years of the eruption.

Photo by Jim Luhr, 1997 (Smithsonian Institution).
The small light-colored spire in the center of the photo is the renowned steeple of the church of San Juan Parangaricutiro, which was surrounded by lava flows from Parícutin volcano in 1944 in this view from the NE. The steep-sided, viscous lava flows in the background were erupted later, during 1944-46. This is one of numerous lava flows within the Michoacan-Guanajuato volcanic field.

Photo by Jim Luhr, 1997 (Smithsonian Institution).
The renowned Parícutin scoria cone, which grew from a Mexican cornfield beginning in 1943, is one of the roughly 1,000 cones that form the massive Michoacán-Guanajuato volcanic field in central Mexico. White mineral deposits formed across the top of Nuevo Juatita in the foreground, a NE-flank vent that was the main source of lava flows during the last five years of the 1943-1952 eruption.

The Jorullo cone (right-center) is seen here from the SSW with Cerro la Pilita cone in the foreground. The small, less-vegetated cones immediately to the left are the SW-flank vents that produced lava flows during the middle part of the 1759-1774 eruption. Cerro la Pilita is an older cone that produced pre-historical lava flows along a narrow channel to the SW.

Photo by Jim Luhr, 1997 (Smithsonian Institution).
A nighttime Strombolian eruption at Parícutin ejects incandescent blocks and bombs onto the flanks of the scoria cone. Ejecta like this accumulated around the vent to build the cone during February 1943 to February 1952.

The Valle de Santiago in the NE part of the Michoacán-Guanajuato volcanic field NW of Lake Yuriria contains a group of maars formed by phreatomagmatic eruptions. The maars, four of which are lake-filled, range from 0.8 to 1.8 km in diameter, are 80 to 180 m deep, and are probably Holocene in age. This photo shows the Hoya Rincón de Parangüeo maar at the northern end of the group.

Paracho volcano is one of the many cones of the Michoacán-Guanajuato volcanic field. It is seen here from the west with its summit crater filled by a flat-topped lava dome that is the site of a radio antenna station. The dome fills the upper end of a large erosional valley that extends down the flank from the summit. Edifice collapse has occurred on the eastern side of the volcano, producing a major debris avalanche deposit covering an area of about 175 km2.

Lava flows from Parícutin (upper center) within the Michoacan-Guanajuato volcanic field cover much of the northern half of this photo. The small white dot immediately NE of the cone is the flank vent of Nuevo Juatita. The latest lava flows that formed during 1952 originated from this vent and form the darker-colored flows that extend to the SE. Cerro Tzirapan is the larger scoria cone near the center, and older cones are to the upper left.

Ashfall from Hoyo el Huanillo scoria cone (lower left) was radiocarbon dated to have formed about 9,300 years ago within the Michoacan-Guanajuato volcanic field. A small ash-covered lava flow extends a short distance to the NW of the cone, which is located 35 km NE of Parícutin. The Cerro Cucundicata scoria cone is to the lower right, and the Cerro Borrego and Cerro Tarucun cones are to the N, NE of the town of Cherán. The eroded Cerro Pacaracua edifice forms much of the upper part of the photo.

Jorullo volcano and associated lava flows in the Michoacan-Guanajuato volcanic field are visible in the bottom of this photo. Four NE-SW-trending vents flank the main cone, which erupted during 1759-1774. The 1759-74 lava flows appear in varying shades of gray, with the initial (and largest) flows being lighter in color (due to partial ash cover), and the most recent ash-free lava being darker and extending to the NW and NE. Jorullo lies about 80 km SE of Parícutin.

Aerial photo by Comisión de Estudios del Territorio Nacional (CETENAL).
Cerro el Jabalí (upper left) and the adjacent Cerro el Sapien (immediately to the east) of the Michoacan-Guanajuato volcanic field produced the unvegetated lava flow extending across the top of the photo. Ashfall from Cerro el Jabalí scoria cone, located about 15 km SE of Parícutin, erupted about 3,830 years ago. The city of Uruapan is in the right side of the photo, south of the circular Costo (Cerro Cotji) maar.

Volcán la Mina is the scoria cone near the center-left margin of the photo with the lava flow emplaced through the collapsed NE crater rim. It formed about 17,170 years ago within the Michoacan-Guanajuato volcanic field, around 90 km ENE of Parícutin. The SW cone containing a crater that also opens to the NE is Volcán el Melón (lower left), which was the source of a lava flow that traveled east to the present-day outskirts of the village of Capula.

Aerial photo by Comisión de Estudios del Territorio Nacional (CETENAL).
This aerial photo shows part of the Michoacan-Guanajuato volcanic field. Cerro el Pueblito (upper left), radiocarbon dated to about 29,000 years ago, produced the lava flow that extends eastward across the photo that flowed around the older Cerro las Cabras cone to the right. South of this lava flow is the La Vibor lava flow. Cerro Arena is the cone near the center of the photo.

The large forested (dark) area near the center of the photo is Cerro Tecolote, an eroded stratovolcano located roughly 50 km NE of Parícutin within the Michoacan-Guanajuato volcanic field. Cerro las Cabras (upper left) is a scoria cone that produced the lava flow extending across the upper part of the photo. Mexican Highway 15 travels across the flow, which is of Pleistocene age. Cerro Pajarito is one of the scoria cones south of Cerro Tecolote, and another cone is seen here on the SW flank.

The Hoya Rincón de Parangüeo maar rises directly above the town of the same name located on the lower southern flank. A brackish lake of seasonally variable size partially fills the floor of the 2-km-wide maar, seen here from its southern rim. The high point on the northern rim rises 450 m above the crater floor. Rincón de Parangueo is part of the Valle de Santiago maar field on the NE side of the Michoacán-Guanajuato volcanic field and is about 7 km NW of the town of Valle de Santiago.

Geologist Todd Housh observes pyroclastic surge deposits in the wall of an abandoned quarry on the north flank of Hoya Estrada maar, directly west of the town of Valle de Santiago. The exposure shows laminar and dune form-bedded surge deposits at the bottom with laminar ashfall layers at the top. The direction that the pyroclastic surges traveled was from right to left.

The walls of a quarry on the SW flank of Hoya Estrada maar close to the city of Valle de Santiago show a spectacular sequence of deposits from the maar-forming eruptions. Most of the outcrop consists of gray-colored dominantly planar pyroclastic surge beds. The three prominent light-colored layers are ashfall deposits. The largest ash layer is about 2 m thick just above the middle of the outcrop in this view looking towards the vent.

Several maars of the Michoacan-Guanajuato volcanic field are visible in this photo. The 600-m-wide Hoya Solis maar is seen from the SW rim of Hoya Blanca maar, immediately SW of the city of Valle de Santiago. The rim of Hoya de Cintora maar lies beyond Hoya Solis below the far-left horizon.
