Level 1 — Absolute Beginner
A big earthquake hit Flores Island in Indonesia. The earthquake happened early in the morning.
The earthquake was very strong. It was a magnitude 7.7 earthquake.
At least 47 people died. Many houses broke, and some roads are blocked.
Rescue workers are helping people. They are trying to reach places that landslides have blocked.

Level 2 — Elementary
A magnitude 7.7 earthquake struck off the coast of Flores Island in eastern Indonesia early Saturday morning, local time. The quake's center was about 68 kilometers northwest of the city of Ende.
Indonesia's disaster agency said at least 47 people died and about 50 more were hurt. More than 346 houses were damaged, and 157 of them were badly damaged.
The earthquake also damaged schools, health centers, and government buildings. About 2,000 residents left their homes and moved to safer places.
Officials warned about a possible tsunami right after the quake, but they later canceled the warning. More than 230 aftershocks shook the island, and the strongest one measured magnitude 6.2. Rescue teams are still trying to reach the area closest to the earthquake's center, because landslides have blocked the roads there.

Level 3 — Intermediate
A magnitude 7.7 earthquake struck off the northern coast of Flores Island in Indonesia's East Nusa Tenggara province early Saturday, with an epicenter roughly 68 kilometers northwest of the city of Ende, according to Indonesia's National Disaster Mitigation Agency (BNPB).
The death toll has climbed to at least 47, and officials warn it may rise further as search and rescue operations continue. About 50 people were injured, and the quake damaged more than 346 houses, 157 of them severely, along with 87 schools, 18 health facilities, five houses of worship, and six government offices.
Indonesia's meteorological agency briefly issued a tsunami warning for nearby coastlines, urging residents to move away from beaches and rivers to higher ground, before lifting the warning once assessments showed no significant wave threat had developed. More than 230 aftershocks have rattled the island since the initial quake, the strongest reaching magnitude 6.2.
Rescue crews have not yet reached Nagekeo, the regency closest to the epicenter, because landslides triggered by the quake have blocked roads and disrupted communications with the area. Indonesia sits on the Pacific Ring of Fire, a zone of intense seismic and volcanic activity that makes the archipelago especially vulnerable to powerful earthquakes.

Level 4 — Advanced
A magnitude 7.7 earthquake ruptured off the northern coast of Flores Island in Indonesia's East Nusa Tenggara province at 5:58 a.m. local time on Saturday, its epicenter roughly 68 kilometers north-northwest of the regional hub of Ende, Indonesia's National Disaster Mitigation Agency (BNPB) reported.
The confirmed death toll had climbed to at least 47 by Sunday, with roughly 50 additional injuries, and officials cautioned that the figure could still rise as search and rescue operations reach more remote, hard-hit villages. Structural damage was extensive: more than 346 houses were affected, 157 of them severely, alongside 87 educational facilities, 18 health facilities, five houses of worship, and six government offices, according to the agency's preliminary assessment.
The country's meteorological, climatological, and geophysical agency (BMKG) issued a tsunami warning for the surrounding coastline in the quake's immediate aftermath, urging coastal and riverside residents to evacuate to higher ground, before withdrawing the advisory once modeling indicated no significant wave had materialized. The seismic sequence has proven unusually prolonged, with more than 230 aftershocks recorded across the island in the following day, the largest measuring magnitude 6.2, complicating both structural-safety assessments and rescue logistics.
Emergency responders had yet to reach Nagekeo Regency, the administrative area nearest the epicenter, as of the latest reports, with landslides triggered by the initial rupture severing roads and disabling telecommunications infrastructure across the district. The event underscores Indonesia's acute exposure to seismic hazard as an archipelago straddling the Pacific Ring of Fire, where the collision of the Indo-Australian and Sunda tectonic plates generates some of the world's most frequent and destructive earthquakes.
