stratovolcano
Northern Chile, -23.37°S / -67.73°W 
Summit height: 5592 m / 18,346 ft
Aktueller Status: normal / ruhend (1 von 5)
Last update: 19 Mär 2025 (Smithsonian / USGS Weekly Volcanic Activity Report)
Láscar volcano in northern Chile is the most active of the northern Chilean Andes. Lascar is an andesitic-to-dacitic stratovolcano with 3 overlapping summit craters. Large lava flows are visible on its NW flanks.
Lascar is flanked 5 km to the east by the older, but higher Volcán Aguas Calientes stratovolcano.
Lascar has had a number of small to moderate explosive eruptions in historic times, as well as a few larger eruptions that caused ashfall hundreds of kilometers away. The biggest eruption of Lascar in historical time was in 1993 and produced pyroclastic flows, which traveled 8.5 km NW of the summit, and ashfall in Buenos Aires.

Beschreibung
The older Volcán Aguas Calientes has a well-developed summit crater and a lava flow near its summit may be of Holocene age.Younger Láscar volcano consists of 2 major edifices; activity built a cone to the east and then shifted to the west, where a second cone was built.
The largest eruption of Lascar took place about 26,500 years ago, and following the eruption of the Tumbres scoria flow about 9000 years ago, activity shifted back to the eastern cone, where 3 overlapping craters were formed.

Anmerkung:
Unsere Liste von Vulkanausbrüchen orientiert sich eng an der Datenbank des Global Volcanism Project (GVP) des Smithsonian Instituts, der international anerkanntesten globalen Datenquelle für Vulkanausbrüche. Sie schließt aber auch bedeutende Eruptionsepisoden oder damit zusammenhängende Vulkanereignisse ein. Unter "Vulkanausbrüchen" versteht man in der Regel meist Serien einzelner Eruptionsepisoden, die zeitlich aufeinander folgen oder sich (bei mehreren beteiligten Ausbruchspunkten an einem Vulkan) auch überlappen können und unter Umständen viele Jahre, Jahrzehnte oder noch länger andauern können. So ist z.B. die aktuelle Tätigkeit des Stromboli als ein einziger Ausbruch verstanden, der seit 1934 anhält.

2006-07 activity
After the strong ash emissions between 18-23 April 2006, several small to moderate (probably) phreatic explosions occurred throughout the rest of 2006 and into 2007 at irregular intervals.
On 11 March 2007 an ash cloud from Láscar rose to 5.5-6.7 km altitude and drifted E. On 23 May, 2007, an ash plume from Láscar rose to an altitude of 9.1 km and drifted SSE. On 18 July 2007, an ash plume rose to altitudes of 7.6-9.1 km and drifted NE. After July, 2007, Lascar calmed down.

2006 April eruption
An eruption at Lascar volcano started on 18 April 2006 and lasted 5 days. The first of 4 explosions on the first day produced an ash plume that reached ca. 10 km above the volcano (ca. 16 km altitude) and was visible from the El Abra cooper mine 220 km NW of the volcano.

2005 eruption
During February to May 2005, a number of mostly smaller phreatic eruptions occurred at Lascar volcano.
A more powerful eruption occurred on 4 May, producing an ash column that reached a height of 11 km and caused fine ash fall in the city of Salta located 285 km SSE of the volcano.

1993 subplinian eruption
The largest eruption of Lascar volcano known in historical times was in 1993: The explosive eruption began late on 18 April with a series of powerful explosions and intensified on 19 April, when it produced a plinian ash column reaching 20-22 km height above the crater. Large pyroclastic flows traveled 7.5 km NW and light ashfall (<0.1 mm) was reported as far as Buenos Aires, Argentina, 1,500 km SE of the volcano.
The area affected by ash fall covered more than 850,000 sq km and stretched into north-central Argentina, southern Paraguay, Uruguay, and southern Brazil.

+When was the last eruption of Lascar volcano?
The last confirmed eruption of Lascar occurred während 2022 - 2023.
+How often does Lascar volcano erupt?
Since 1848, Lascar volcano has had at least 30 historically documented eruptions. This means that it erupts on average every 5.9 years.
