Historical reference, not a live update. The Nepal earthquake 2015 sequence began with a reviewed magnitude 7.8 event on 25 April. The selected records below show the main shock and three later large events. The list is useful for understanding the sequence, but it is not a complete aftershock catalog or a full damage history.

The 2015 Nepal earthquake sequence began with a reviewed M7.8 earthquake and included later large events on 25 April, 26 April and 12 May. The practical lesson is to plan for repeated shaking: secure heavy items, practise drop, cover and hold on, and keep water and communication tools reachable today.

Nepal earthquake 2015 timeline

The times above are UTC. They are rounded to the nearest second from USGS data. The mainshock location uses the USGS label. Later records use broader labels. This page does not make them more precise.

What the records show

The first event, us20002926, is the reviewed M7.8 earthquake 67 kilometres north-northeast of Bharatpur. USGS gives its time as 06:11:25 UTC. It gives the depth as 8.22 kilometres. The date was 25 April.

The selected records show that the sequence did not end with the first shock. USGS records the M6.6 event us2000292y about 34 minutes later. The catalog records M6.7 event us200029bt on 26 April and M7.3 event us20002ejl on 12 May. Each event has its own source ID.

The catalog also records the mainshock as a shallow event, with a depth of 8.22 kilometres and coordinates of 28.2305 north and 84.7314 east. Those details help explain why the record is more than a rounded headline number. The event has a reviewed status and a moment magnitude value in the USGS response. The later entries are also reviewed records, but their place labels differ. Keeping each label intact avoids turning a catalog summary into a false map claim.

This is a selected timeline. It does not list every aftershock, felt report or impact. It does not add casualty totals or building damage.

Those claims need separate official records. The useful point is simple. A family plan must work after the first earthquake and during later shaking.

What USGS documented about the impact

USGS's longer historical review describes a large humanitarian impact. It reports about 9,000 fatalities and 23,000 injuries. It also reports more than 500,000 destroyed houses and about 270,000 damaged houses. These are USGS totals. They are not estimates from the event catalog.

The same USGS review says the earthquake moved Mount Everest about 3 centimetres southwest. Scientists also studied the event and its aftershocks. They examined how ground conditions shaped shaking and damage. An earthquake is not only a catalog number. Location, depth and buildings affect what people experience.

These facts have limits. They describe the 2015 disaster at a broad scale. They do not predict the next earthquake.

For household choices, use the separate Ready.gov guidance below. Secure heavy items. Plan communication. Practise the protective response.

Nepal earthquake 2015 preparedness lessons

Ready.gov recommends a family communication plan. Choose an out-of-area contact and two meeting places. Write down how children, older adults, pets and people with access needs will be supported. Keep a paper copy at home.

Secure heavy furniture. Move heavy or breakable items to low shelves. Check rooms where people sleep and spend time. Keep water, a flashlight, medicines and a way to receive official information somewhere easy to reach.

The site's family emergency plan covers communication. The earthquake emergency kit guide covers supplies. These pages add present-day help. They do not describe what every Nepal household had in 2015.

What to do when shaking starts

Ready.gov's earthquake guidance is simple. Inside, stay inside and avoid doorways. Drop onto your hands and knees. Cover your head and neck with one arm and hand.

Crawl under a sturdy table or desk if one is close. Hold on until the shaking stops.

In bed, turn face down and cover your head and neck with a pillow. Outside, move to an open area away from buildings, trees, streetlights and power lines, then drop and cover. While driving, pull over, stop and set the parking brake.

After the shaking, expect more movement. Check for injuries if safe. Stay out of damaged buildings.

Watch for gas or water-line problems. Follow current local instructions. Ready.gov also recommends texts and official alerts when phone networks are busy.

A five-minute preparedness check

Pick the household contact and meeting places. Find sturdy cover in the living room, bedroom and kitchen.

Move one heavy item lower or secure one tall piece of furniture. Put water, a flashlight and a radio within reach.

Then practise drop, cover and hold on. Repeat the drill after a room changes or a new household member arrives.

History cannot predict the next earthquake. Practice can reduce hesitation when the ground moves.

Verdict

The Nepal earthquake 2015 sequence is a clear reminder to plan for more than one shock. Use the USGS records for history, Ready.gov for safety steps, and a household plan that keeps people, water and communication tools ready.

Questions people also ask

What happened in Nepal on 25 April 2015?

USGS lists a reviewed magnitude 7.8 earthquake at 06:11:25 UTC on 25 April 2015, 67 kilometres north-northeast of Bharatpur, Nepal. This page uses the USGS catalog for the event timeline and does not present old reports as current news.

Which aftershocks are included in this timeline?

This selected timeline includes three later reviewed USGS events: a magnitude 6.6 event on 25 April, a magnitude 6.7 event on 26 April, and a magnitude 7.3 event on 12 May. It is not a complete aftershock catalog.

What should a family do before an earthquake?

Ready.gov recommends a family communication plan, meeting places, supplies for several days and securing heavy items. Write the plan down, keep water and a light reachable, and practise drop, cover and hold on with everyone in the home.

What should people do during an earthquake?

If you are inside, stay inside and avoid doorways. Drop onto your hands and knees, cover your head and neck, and hold on under sturdy furniture if it is close. If you are outside, move away from buildings, trees and power lines.

Is this a current Nepal earthquake update?

No. It is a historical reference about the 2015 sequence. For current earthquake information, use the USGS event catalog and local emergency authorities. The preparedness advice is general guidance from Ready.gov, not a report of current conditions.
