This video was filmed during the major eruption of Mount Semeru in Lumajang, East Java, Indonesia, on 19 November 2025. The eruption produced massive ash plumes and sent pyroclastic clouds toward nearby villages.

I recorded this footage from a safe distance shortly after the mountain erupted, capturing the moment thick grey ash rose rapidly into the sky. The atmosphere turned dark as volcanic material spread across the area, and people around me reacted in shock and confusion.

This was an unexpected event, and within minutes residents began to evacuate while authorities issued an emergency alert and raised the volcano’s status to Level IV (Awas). My recording documents the intensity of the eruption as it happened in real time and shows the immediate impact on the surrounding environment.

This footage provides raw, on-the-ground visuals that help illustrate the scale and urgency of the Semeru eruption — valuable for news reports, analysis, and documentation of natural disasters.

1. What exactly is happening in the video?
The video shows Mount Semeru erupting and releasing a massive, thick ash plume into the sky. The footage captures the moment the ash cloud expands and rises dramatically above the mountain in real time.


2. Who is involved (names and ages if possible)?
There are no direct participants in the eruption, but the individuals present around the filming location include:

Aldi, local resident (early 30s)

Putri, local resident (mid 20s)

Slamet, the driver and elder (around 60 years old)
They were nearby during the recording but not directly in the ash-cloud zone.

3. Where, specifically, did it happen?
The eruption occurred at Mount Semeru, located in Lumajang Regency, East Java, Indonesia.
The video was filmed facing the volcano from a safe distance within the Lumajang area.
Gladak perak Bridge.

4. When, specifically, did it happen?
The video was filmed on 19 November 2025, during the active eruption phase of Mount Semeru.

5. Who filmed the video and on what device was it filmed?
The footage was filmed by aldi (the uploader) using a smartphone (Android device) with video stabilization enabled to capture a cinematic-style shot.

6. Why did it happen?
Mount Semeru is one of Indonesia’s most active volcanoes. The eruption was caused by natural volcanic activity, including pressure buildup within the volcano’s magma chamber, resulting in an explosive release of ash, gas, and pyroclastic material.

7. Have you shared this video with any other licensing agencies before Newsflare? (LADbible, Storyful, Viralhog, Jukin, etc.)
No — this video has not been shared with any other licensing agencies or publishers before Newsflare.
This is an exclusive upload.

8. Any additional information?
The visual style was intentionally made cinematic to show both the beauty and the danger of the eruption. The ash plume was extremely large and visible from kilometers away. Many residents were still in the process of evacuating from nearby villages, and the atmosphere was tense and uncertain. The video was captured safely with no one harmed.
