September 22 Peru earthquake : Latest news

Boulevard en Chincha Alta

Update September 23 – 5 PM UTC : The Peruvian local press gave us some more information on what people experienced during this earthquake. Power was off for at least 7 hours in many villages around the epicenter. People ran on the street (almost everybody is still running away in panic from the inside of their houses, although EVERY EARTHQUAKE SPECIALIST IS ADVISING TO DROP, COVER AND HOLD).

Telephone lines did not worked for some time.
The Telefonica and Movistar cellular networks were down too. Earthquake Report is very curious for the reason, as this earthquake was really not that heavy.
In New Zealand Christchurch cellular phones kept working for many hours on batteries. Is the Peruvian cellular network (a prime earthquake sensitive country) equipped with batteries ?
People did not sleep anymore after the quake and stayed for a longer time in the streets as they where frightened for aftershocks.
The quake lasted for about 30 seconds.
The 10 uninhabitable damaged houses were mostly build in brick and adobe, materials who are very vulnerable for earthquakes. The sector most hit was San Clemente.
More damage was made to houses, but mostly the damage was limited to cracks in walls.

Earlier reports

Update 17:26 UTC : 10 houses badly damaged in San Clemente. The Civil Defense is still receiving reports of some other areas, but San Clemente has been hit the worst so far. People have been evacuated from these houses as are uninhabitable. Earthquake Report did not trust the earthquake after it happened because of the Magnitude and the poor construction of some houses.

Earthquake Report comment :
A very powerful but luckily rather deep earthquake did strike the Peru coast near Chincha Alta.
The earthquake was felt as far as Lima. The felt reports from USGS are reporting a Mercalli value of IV to V directly in the epicenter area = light to moderate shaking.
The theoretical Mercalli values from the USGS shaking map (see below) were calculated as V to VI near Chincha Alta = moderate to strong shaking.
The earthquake happened in the middle of the Peruvian night at 3 AM.
417,000 people are living within a radius of 50 km from the epicenter.
Due to the depth, millions of people will have felt the tremor, but a lot of them will have trough it.
GDACS Issues a GREEN earthquake report after the earthquake = very limited chance on injuries and damage.
The same earthquake at a depth of 20 km would have been a totally different experience.
USGS expects a Mercalli V shaking in Chincha Alta, San Clemente and Pisco = moderate shaking
USGS expects a Mercalli IV shaking in Villa Tupac Amaru,Quilmana, Imperial and Ica = light shaking
Weak shaking in Lima (maximum Mercalli III)
