What Happened on August 14 2026: The 7.7 Magnitude Indonesia Earthquake That Struck Flores
The Indonesia earthquake of August 14, 2026, measured 7.7 on the moment magnitude scale according to the United States Geological Survey, struck at a depth of only 10 kilometres below the seafloor approximately 68 kilometres north-northwest of the city of Ende in East Nusa Tenggara province at 5:58 a.m. local time, making it a shallow earthquake with the capacity to generate severe surface shaking across a wide area.
Shallow earthquakes radiate more seismic energy toward the surface than deeper events. At 10 kilometres depth, the distance between the rupture point and populated areas on Flores was small enough to translate the full force of a 7.7 magnitude event into severe ground shaking at the surface. The United States Geological Survey estimated that approximately 500,000 people were exposed to very strong or severe shaking following the event – shaking that USGS describes as capable of causing slight to moderate damage in well-built structures and serious damage in poorly built ones.
Two aftershocks followed the main event. Indonesia’s Meteorology, Climatology and Geophysics Agency, known as BMKG, confirmed the earthquake and activated emergency response protocols within minutes, including the immediate issuance of a tsunami watch for coastal provinces.

Death Toll and Building Damage Across Flores: Ende, Labuan Bajo, Maumere, and Sikka
At least five people were confirmed dead following the Indonesia earthquake of August 14, 2026, with the heaviest documented structural damage recorded across the tourist hub of Labuan Bajo, the city of Ende nearest the epicentre, the port city of Maumere, and the coastal district of Sikka, where the roof of a seminary assembly hall collapsed onto students attending morning Mass.
In Labuan Bajo, the main gateway to Komodo National Park and one of Indonesia’s most visited tourist destinations, a building at the Jayakarta Hotel suffered a structural collapse. Videos posted on social media showed buildings falling and residents running in the streets as dust filled the air over the town. International visitors were among those evacuated from the area.
In Sikka, students at the Roman Catholic St. Peter Major Seminary were attending morning Mass when the assembly hall roof came down. The seminary’s rector, Rev. Guidelbertus Tanga, described the moment: “Our students and nuns ran out in panic beneath a collapsing roof.” He confirmed that at least one priest suffered a broken leg after jumping from the second floor of a building during the quake.
Across Flores, multiple hospitals evacuated their patients as a safety precaution. Hospital staff moved beds, IV stands, and oxygen cylinders outdoors and set up temporary treatment areas in the grounds while buildings were assessed for structural integrity. East Manggarai also reported building damage, documented by AP photographers on the ground.
| Location | Damage Reported | Notes |
| Labuan Bajo | Jayakarta Hotel building collapsed | Tourist hub; gateway to Komodo National Park |
| Ende | Buildings damaged; nearest major city to epicentre | 68 km from epicentre |
| Maumere | Buildings collapsed; BASARNAS deployed | Maumere Search and Rescue first on scene |
| Sikka – seminary | Assembly hall roof collapsed during morning Mass | One priest broke leg; students and nuns evacuated |
| East Manggarai | Building damage documented | AP photographer present |
| Multiple hospitals across Flores | Patients evacuated to outdoor areas | Buildings closed pending structural inspection |
The death toll stood at a minimum of five at the time of this publication and is expected to rise as search and rescue teams reach more remote communities across Flores’s mountainous interior.
Indonesia Earthquake Tsunami Warning: Why It Was Issued, Which Provinces Were Covered, and Why It Was Lifted
Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) issued a tsunami warning for coastal communities in East Nusa Tenggara, West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi provinces following the 7.7 magnitude earthquake, urging residents to move away from beaches and riverbanks and for those on coastlines to evacuate immediately to higher ground, before lifting the warning after monitoring confirmed no significant sea-level changes.
A tsunami warning following a shallow, high-magnitude offshore earthquake is standard protocol in Indonesia. The combination of a 7.7 magnitude event at only 10 kilometres depth, with an epicentre below the Flores Sea, created precisely the conditions that historically have produced dangerous tsunami waves. BMKG’s early warning system, significantly upgraded following the 2004 Indian Ocean tsunami that killed over 230,000 people across the Indian Ocean basin, requires automatic warning issuance pending confirmation from tidal gauges and sea-level sensors along the coast.
The sensors showed no anomalous sea-level rise consistent with incoming tsunami waves. BMKG confirmed no significant sea-level changes had occurred and lifted the warning. Residents who had evacuated to higher ground along coastal areas were advised of the all-clear, though BMKG continued monitoring for aftershock-generated wave activity.
Villagers in coastal communities including Talibura were seen fleeing their homes and heading to higher ground after the quake. A 51-year-old resident of Talibura described the earthquake as “massive” and said the shaking forced her from her home. The 2021 Flores earthquake, which measured 7.3 to 7.4 magnitude, generated a tsunami of 7 centimetres – too small to cause harm. The 2026 event did not produce a measurable tsunami.
Why Indonesia Has Major Earthquakes: The Ring of Fire, Tectonic Plates, and Flores Seismic History
Indonesia is one of the world’s most seismically active countries because it sits at the convergence of multiple major tectonic plates on the Pacific Ring of Fire, an archipelago of 17,000 islands spanning the boundaries of the Eurasian, Australian, Pacific, and Sunda plates, where the constant movement and collision of these plates generate tens of thousands of earthquakes annually.
Approximately 90% of the world’s earthquakes and 75% of its active volcanoes are located along the Ring of Fire, the belt of tectonic fault lines encircling the Pacific Ocean. Indonesia sits at one of its most concentrated junctions. In the Flores region specifically, the island sits above the Flores back-arc thrust fault system, which runs along the northern side of the island and is directly responsible for the seismicity in the Flores Sea. This same fault system produced the December 2021 Flores earthquake, which measured 7.3 to 7.4 magnitude, killed one person, injured 173, and generated a minor 7-centimetre tsunami.
The 2026 earthquake is the most powerful to strike the Flores region in recent years, and its shallow depth of 10 kilometres amplified its surface impact well beyond what a deeper event of the same magnitude would have produced. Flores itself is a mountainous island of approximately 2 million people, most of whom live in small villages across difficult terrain. That geography, while defining for the island’s beauty and ecological importance as a gateway to Komodo National Park, also slows rescue operations and means that the full extent of damage in interior communities will take days to confirm.
The broader seismic picture of 2026 has been defined by a pattern of major earthquakes across different regions. Just four days before the Flores event, on August 10, 2026, a 7.4 magnitude earthquake struck Colombia’s Chocó department, killing over 254 people.
Emergency Response to the Indonesia Flores Earthquake: BASARNAS, Hospital Evacuations, and Government Action
Indonesia’s National Search and Rescue Agency, known as BASARNAS, deployed rescue teams to Maumere and surrounding districts in East Nusa Tenggara immediately following the August 14 earthquake, with images confirming personnel on the ground clearing debris from collapsed buildings while authorities coordinated a wider disaster response across the affected provinces.
BASARNAS is the principal emergency response body for earthquake and disaster search and rescue in Indonesia. Following the initial quake, teams from the Maumere Search and Rescue Agency confirmed the first casualties and began assessing access to affected villages. In areas with road damage, access for heavy rescue equipment was limited.
Across Flores, hospitals adapted rapidly to the emergency. At several facilities, all patients were moved outdoors, with medical staff setting up field treatment areas using portable equipment. Beds, intravenous stands, and oxygen cylinders were repositioned to outdoor locations while structural engineers began assessing building safety.
In Labuan Bajo, the international tourist presence added a layer of complexity to the emergency response. Visitors from multiple countries were in the area given its status as the departure point for Komodo National Park trips. Local authorities worked to account for and assist both domestic residents and foreign nationals.
BMKG continued to monitor aftershock activity following the lifted tsunami warning. Residents in coastal areas were advised to remain alert. The Indonesian government’s disaster management agency coordinated communications between provincial authorities and national emergency bodies, with real-time updates issued through official channels.
Indonesia Earthquake August 14 2026: What Is Known and What Rescue Teams Are Still Discovering
The 7.7 magnitude Indonesia earthquake that struck Flores on August 14, 2026 is one of the most powerful to hit the island in recent years and has produced widespread structural damage across East Nusa Tenggara, with at least five people confirmed dead, approximately 500,000 exposed to severe shaking, buildings collapsed across Ende, Labuan Bajo, Maumere, and Sikka, a tsunami warning issued and lifted, and BASARNAS rescue teams working through collapsed structures in communities that are difficult to access. Flores is an island of approximately 2 million people spread across mountainous terrain, and the confirmed casualty and damage figures will continue to rise as rescue teams reach more remote areas.

Frequently Asked Questions
What was the magnitude of the Indonesia earthquake on August 14, 2026?
The Indonesia earthquake on August 14, 2026, measured 7.7 on the moment magnitude scale, according to the United States Geological Survey. The epicentre was located 68 kilometres north-northwest of Ende in East Nusa Tenggara province, at a shallow depth of 10 kilometres below the seafloor.
Was there a tsunami warning after the Indonesia earthquake and was it lifted?
Yes, Indonesia’s BMKG issued a tsunami warning for East and West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi following the earthquake. The warning was later lifted after monitoring showed no significant sea-level changes at coastal sensor stations consistent with incoming tsunami waves.
Why was the Indonesia earthquake so damaging despite occurring offshore?
The earthquake struck at a shallow depth of only 10 kilometres. Shallow earthquakes radiate more seismic energy toward the surface than deeper events. Approximately 500,000 people were exposed to very strong or severe shaking, which is capable of serious damage in poorly built structures across the Flores island region.
What happened at the seminary in Sikka during the earthquake?
Students at the Roman Catholic St. Peter Major Seminary in Sikka were attending morning Mass when the assembly hall roof collapsed. Seminary rector Rev. Guidelbertus Tanga confirmed students and nuns fled in panic as the roof came down. One priest broke a leg after jumping from the second floor of a building.
Why does Indonesia experience so many earthquakes?
Indonesia sits at the convergence of the Eurasian, Australian, Pacific, and Sunda tectonic plates on the Pacific Ring of Fire. This makes it one of the most seismically active countries on Earth, registering tens of thousands of earthquakes annually across its archipelago of 17,000 islands.
How does the 2026 Flores earthquake compare to the December 2021 Flores earthquake?
The December 2021 Flores earthquake measured 7.3 to 7.4 magnitude and resulted in 1 death and 173 injuries. The 2026 event at 7.7 magnitude is stronger, struck at a shallower depth, and produced significantly more structural damage across Ende, Maumere, Sikka, and Labuan Bajo, with at least five deaths confirmed.
What is Labuan Bajo and why was it affected by this earthquake?
Labuan Bajo is a coastal town on the western tip of Flores Island and the primary tourist gateway to Komodo National Park, home to the world’s largest lizards. The earthquake caused a building collapse at the Jayakarta Hotel in Labuan Bajo, affecting residents and international visitors present in the area.
