fyi regarding EMAs, from s9(2)(g)(ii) NEMA Staff if we're seriously considering EMA for this
that we need think about how a nationwide one might work vs multiple groups.
If multiple groups send, then those who are on the boundary between groups
will get multiple messages. We also need to make sure that the groups are all
saying similar things so people don't receive conflicting messages.

their regions. CDEM Groups also need to be aware of the hotspots in their
regions that may see more inundation for beach and marine than is typical for
other areas.

Official 
There is no change to the current assessment
 
The data ac
ross the Pacific is matching their modelling, so their assessments are
the 
looking robust.
The current threat maps are expected to remain in place until around midday
tomorrow. There is then likely to be a de-escalation from midday tomorrow
through to midnight, zone by zone, starting on the West Coast.
Some areas could be under a beach and marine threat for as a long as two days
under 
after the earthquake (midday Friday).
There is also no change to Scott Base, they remain under a beach and marine
threat with a 7am arrival time.
The TEP will reconvene at 8am tomorrow, but there are seismologists
monitoring overnight for escalation.

TSUNAMI ADVISORY: Strong and unusual currents and unpredictable surges at
the shore are expected following a magnitude 8.8 earthquake near Kamchatka,
Russia.
Strong currents and surges can inju
re and drown people. There is a danger to
swimmers, surfers, people fishing, and anyone in or near the water close to the
shore.
Released 

People on boats, live-aboards and at marinas should leave their boats/vessels
and move onto shore. Do not return to boats unless instructed by officials.
IF YOU ARE ONSHORE, YOU DO NOT NEED TO EVACUATE. But STAY AWAY
FROM THE WATER, including beaches, shore areas, harbours, marinas, rivers
1982
and estuaries. DO NOT GO SIGHTSEEING.
This advisory is for all coastal areas of the North Island, Great Barrier Island, the
South Island, Stewart Island and the Chatham Islands.
Act 
The threat is likely to remain in force until at least midday today.
Tsunami activity has already reached parts of New Zealand. The first currents

many hours. The threat must be regarded as real until this Advisory is
cancelled.

Information 
Morning all, without wanting to come across as too defensive - there is no
indication from telco's that there has been any 'glitch'. We're well aware that
phones can receive the alert multiple times for a variety of reasons. Switching
from 3/4g, switching towers for better reception, a tower coming online for
capacity reasons or just a phone updating and reconnecting to the network can
Official 
cause this. There will be those on the cusp of the alerting area who will have
received the message repeatedly for the 12 hours that we broadcast.  I will
reach out to whoevers9(2)(g)(ii) NEMA Staff provider is today, but this is not an uncommon
the 
occurrence.

 Update from the TEP - they are continuing with the same threat level for the

able to de-escalate the threat across the west coasts of both islands. It is
anticipated this will come into place mid afternoon.

Due to the reflections off South America, there continues to be a possibility for
continued beach and marine threat overnight for the east coasts. Chatham

mean the absence of tsunami impacts, potentially strong and unusual currents

Act 
can still occur on the West Coast.". 
• TEP is still waiting on reflected waves from the Americas to inform
decisions for the East Coast.
• This current threat level expected to last at least until 7:30am on 1st August
• Some de-escalation is likely between 7:30 a.m. and midday on 1st August.
Parts of New Zealand could remain under Beach and Marine threat for

go to the beach or marina . It would be great to be able to show what this data

This is delivered via two mechanisms: 
• Advice provided by ESNZ’s National Geohazard Monitoring Centre (NGMC) directly to
NEMA’s Monitoring, Alerting and Reporting (MAR) Centre. This includes the forecast
Act 
maps and Event Arrival Time information.
• Phone calls between the TEP and the National Controller to discuss the analysis,
forward assessments, and to provide the opportunity to ask questions. This helps
inform NEMA’s decision making.
A total of 10 phone calls were conducted between the TEP and NEMA for this event, 
summarised below. 
30 July 1335hrs 
Information 
The EQ is expected to be upgraded from 8.7M to 8.8M. The modelling is indicating a beach and 
marine threat for the entire country, including the Chatham Islands. The Chatham Islands is 
likely to receive the strongest tsunami waves, getting close to a land threat at 0.8m. 
The modelling is not currently showing a land threat, but it remains a possibility. They will stick 
with a beach and marine threat assessment for now, noting the next update is likely to include 
Official 
actual data, as well as modelling. 
the 
30 July 1940hrs 
Still expecting to see beach and marine impacts, including the Chatham Islands, but the 
Scientist in Charge overnight will contact me if this looks like it will escalate to a land threat. 
The first wave arrivals are expected around midnight, and the DART Buoys will give an early 
under 
indication of their arrival from around 9pm. They may indicate an earlier de-escalation for the 
West Coast but there is likely to be some beach and marine threat for parts of the country going 
well into tomorrow. The picture will become clearer overnight. 
30 July 2300hrs 
No change to the threat area being all of New Zealand coasts for beach and marine. The models 
Released 
are looking good with the data matching the models across the Pacific. The current threat 
model will now remain in place until midday tomorrow. 

It is expected there will be de-escalation from midday through to midnight, zone by zone, 
starting on the West Coast. Some areas could remain under threat for as long as two days from 
the earthquake occurring. 
31 July 0845hrs 
No change to the current threat map and it remains valid until midday. 
Tsunami gauges around New Zealand are showing tsunami waves, some as high as 30cm, 
1982
therefore they could be higher along the coast. The Chatham Islands data is as 50cm and 
increasing. Dunedin is also increasing. 
Act 
Some de-escalation can be expected from midday. Wellington is expected to experience waves 
for longer, while Kapiti may de-escalate earlier. 
31 July 1150hrs 
Continues to be the same level of threat for the whole country. Criteria for de-escalation for the 
west coasts of both islands is expected to be met around mid-afternoon. 
The Chatham Islands model ing is showing similar arrivals to earlier to arrive overnight. 
Expecting to receive reflections off South America, possibly overnight for the East Coast. 
Information 
31 July 1500hrs 
The tide gauges for the west coast of the South Island are measuring at just below beach and 
marine thresholds. 
Official 
The west coast of the North Island is trending down. The east coast of both islands is expected 
to receive reflections from South America. There will be a lull and it wil  pick up again overnight. 
the 
31 July 1900hrs 
De-escalation of most of the west coast of the South Island. Things haven’t changed a lot, it’s 
stable and satisfied it’s not going to get any worse. Waiting on reflections on South America to 
under 
arrive and there could still be spots that exceed the 30cm beach and marine threshold. It is 
expected that more zones will be de-escalated tomorrow morning. 
1 Aug 0745hrs 
All of New Zealand has had its threat de-escalated, except for the Chatham Islands. The largest 
wave arrivals on the Chatham Islands have been from the reflected waves off South America. 
Released 
Beach and marine tsunami conditions were observed on the east coast of the South Island 
overnight, with the largest waves heights in Gisborne. 
There remains a low level of activity across the east coast, but below the beach and marine 
threat threshold. 

1 Aug 1250hrs 
All of New Zealand has been de-escalated and there is no longer considered to be a beach and 
marine threat. 
Strong currents are still expected to be observed over the weekend, but the tsunami threat has 
passed. The TEP is standing down for the weekend.
