We conducted the field survey of the tsunami generated by the M8.8 great earthquake in Chile triggeredon 27 February 2010 (UTC). The survey focused on the measurements of tsunami inundation/run-up
height, flow depth, extent of inundation zone, structural damage inspection, and collecting eyewitness
accounts. In total, tsunami heights and flow depths at approximately 155 points were measured along thecoast of Biobio region, Chile, to understand the tsunami features during this event.
Key Words :The 2010 Maule earthquake, tsunami, field survey

1. INTRODUCTION
On 27 February 2010, a megathrust earthquake of M8.8 (Fig.1) generated a destructive tsunami. It struck notonly Chilean coast but propagated all the way to Japan. After the event occurred, the post-tsunami survey team
was assembled, funded by JST, to survey the area of severely affected by the tsunami. The main purpose of thesurvey was to examine the damage, measure the tsunami run-up and inundation height, flow depth and extent
of inundation, and interview the eyewitnesses of the tsunami. A joint survey team was consisted of themembers from SATREPS and the researchers from Central Research Institute of Electric Power Industry (5researchers from Japan and two researchers from Peru).
The following report aims to describe the findings and knowledge from the survey.

day since the mainshock occurred.

2. POST TSUNAMI FIELD SURVEY(1) Logistics
Because the tsunami hit quite long extent of Chilean coast, the survey area needed to be prioritized. We decided
to deploy the most severely affected area in Biobio region. The survey team was deployed along the central
coast of Chile from 18 to 25 April 2010. Fig.2 shows the route of the survey team. Setting the base lodging in
Concepcion, we started the survey on 18 April from Talcahuano to visit eight coastal communities using a car.
(2) Methods
Conventionally, the post-tsunami survey measures tsunami inundation and run-up height, flow depth, andextent of inundation zone. The inundation height is measured as the height of watermarks on structures ordebris on trees above sea level (after tide correction), and the run-up height as the altitude of the inland limit oftsunami penetration. Flow depth is the thickness of tsunami inundation flow measured as the height of thewatermark from the local ground level. Measurements were conducted using the laser range finder (Laser
Technology Inc.) with survey rods and digital cameras with GPS and compass. During the survey, we interviewed witnesses to collect the information of tsunami features (time of the tsunami arrival, polarity of the firstwave, timing of maximum wave). In total, we obtained 155 points along the coast as the measurement oftsunami inundation and run-up heights, and flow depths. Figs. 3 and 4 show the longshore distribution of themeasured tsunami heights and depths. The complete dataset is provided in Appendix. We made the tide correction for all the data by using tide table at Talcahuano.
Along with the field measurements, we used high-resolution optical satellite images to inspect the impact oftsunami disaster. Table 1 is the list of high-resolution satellite images used in the inspection of tsunami-affected area.

3. RESULTS(1) Talcahuano
Talcahuano is the port city in Biobio Region, which contains the naval base, and has approximately 250,000
inhabitants as a population (2002 census). According to the tide gauge record (NOAA, 2010), the first wave oftsunami reached Talcahuano at 3:30 (Local time) with receded wave. After the arrival of first wave, the tidegauge at Talcahuano did not successfully record the tsunami and stopped transmitting data. CATOE (Centro
12

de Alertamiento Temprano y Oficina de Emergencia) reported that the tsunami attacked the coast at least fourtimes with its period of 45 to 60 minutes, and the fourth wave was the largest.
Fig. 5 represents the result of tsunami inundation height measurement in Talcahuano. The tsunami penetrated approximately 300 m inland in the port-town area and more than 1 km in the southern coastal marsh.
Tsunami inundation reached to 6-8 m in port-town area and 10 m in the coastal marsh. This figure also shows
the comparison of pre and post event satellite images in Talcahuano port (Figs. 5(b), (c)). Significant amount ofcontainers and fishing boats were left as tsunami debris, which caused long duration of failure of port andharbor facilities. While the tsunami left considerable damage to the town of Talcahuano (eastern bottom of thebay), no damage was found in the western port area (San Vicente). The measured tsunami run-up height in San
Vicente was 3.4 m (Fig. 5(a)).

According to the interview with eyewitness, the tsunami slightly overtopped the dock of the harbor but did
not inundate out of the port. Possible causes of this discrepancy may be local effect of tsunami source mechanisms and the condition of harbor oscillation related to the size and shape of the bay.
In the town of Talcahuano, the tsunami penetrated with up to 2-3 m of flow depth (Fig. 6). After inspecting
the structural damage in the town, some washed-away structures were found, but it was limited within the port
facilities (north-west) and industrial area (south-west). Most of the structural damage in the town was likely to
be caused by ground shaking, but minor damage, e.g. bending shutters of commercial buildings and broken
windows.
(2) Inspection of satellite images
Inspecting pre and post event satellite images and ground photos helps to understand multi aspects of tsunami
disaster. Fig. 7 is the comparison of pre and post event satellite images in Talcahuano. We acquired thepre-tsunami image from GoogleEarth (QuickBird image taken on 13 April, 2009), and used WorldView-2
pan-sharpened composite image as post-tsunami image. From post-tsunami image and field survey, we foundthe tumbled ship at the west of waterway in Tulcahuano bay that has been stably stood in the bay (even though
it was not in use). In the coastal marsh, considerable changes of shoreline and tsunami debris are seen in thesatellite images, and it was found from the ground photos (Fig. 8) that the coastal sand were eroded by inland
penetration of tsunami.
(3) Detection of salt-water penetration
Since salt-water penetration causes death of vegetation, sometimes it is used as a clear indicator of tsunami
inundation. Using a specific feature of vegetation, i.e. strong absorption of visible red-band and strong reflection of nir-band, NDVI is defined by Equation (1) using the reflectance of near infrared and visible redbands.
NDVI = (Near infrared – Red)/ (Near infrared + Red)

Here, we focused on the eastern bank of the canal in Talcahuano. Fig. 9 indicates the area of investigationand illustrates the result of detecting tsunami penetration by the analysis of WorldView-2 pan-sharpened
multi-spectral image and the multi spectral camera (Tetracam ADC3). As shown in the ground photos (Figs. 9
A and B), considerable inundation was found on the western bank of the canal while the eyewitness testified
that the tsunami slightly overtopped the eastern bank (no inundation in houses). Using the multi spectral
camera that takes visible red, green and near infrared bands, we first calculated NDVI at the top of the bankwhere the tsunami did not overtop (Fig. 9B). As a result, we found that NDVI of the dead vegetation becomesless than 0.3. Using the threshold value determined by the spectral camera, we discuss the salt-water penetration on the eastern bank of the canal. Fig. 9 (c) shows the distribution of NDVI calculated from thepost-tsunami WorldView-2 image (pan-sharpened). NDVI indicates lower value on the western bank (inundated) while relatively higher value on eastern bank (not inundated), and these features are quite consistent
with the ground photos A and B.

(4) Tumbes, Puerto Ingles and Llico
Tumbes locates and Puerto Ingles are the coastal communities, which were isolated by the limited road access.
Fig.10 represents the overview of tsunami height measurements. Tsunami attacked these communities with up
to 11 m height and caused significant damage. Along the coast from Tumbes to Puerto Ingles, the tsunami wasparticularly devastating to demolish the houses of isolated villages (Fig.11). Some survivors mentioned thatthe first wave was withdrawal and the 2nd wave was the largest. Having the experience and lessons from the1960 Chilean tsunami, most of the village people evacuated to the hill immediately after the ground shaking.
They mentioned that the tsunami in 1960 was witnessed only as receded sea and did not cause inundation.

(5) Dichato
Dichato is a coastal village of approximately 3,000 inhabitants (Census 2002), which belongs to the municipality of Tome, located 37 km north of the city of Concepcion. Having a beautiful sandy beach, Dichato wasvery popular in summer for water sports and recreation. Attacked by the tsunami, Dichato became one of themost devastated towns. According to Dichato-Tome Emergency office, 405 families living in camps, and 1223
families were affected on their properties Fig. 14 represents the measured tsunami run-up height and flow
depths. The tsunami penetrated approximately 800 m inland to 10 m altitude. Figs. 15 and 16 illustrates thedevastating damage in Dichato. In this area, most of the houses were washed away and the tsunami left con20

siderable amount of debris. According to the eyewitness who watched the tsunami from 8-story building, thefirst wave of tsunami hit at 5:00 (AM) after most of the people evacuated. In addition, he said that the tsunami
attack was at least 3 times and the 3rd wave was the largest. The other eyewitness said that the tsunami did notcome first from the sea, but from the backside with not so much power (first wave).
Number of fatality and missing reported is 66 and the surviving resident believe that most of the victims are
not from Dichato but tourists or different regions, also heart attack elders or drunken people. This is mainly
because the residents of Dichato knew about the possible tsunami after the earthquake and had evacuation
drills.

6. SUMMARY
In summary, the results of our survey provide a dataset of tsunami run-up and inundation heights, flow
depths and extent of inundation at approximately 150 points. The survey extent was from Dichato to Llico, theareas mostly devastated by the tsunami. The tsunami inundation heights and flow depths were well recorded
and will be used as a constraint in developing tsunami source model to comprehend the features of tsunami
propagation and coastal inundation. Also, we collected the eyewitness accounts to describe the picture oftsunami attack. Most of the eyewitnesses said that the largest tsunami did not occur in the first wave.
Throughout the trip, we found that many of survivors knew the past event 1960 and evacuated immediately
after the ground shaking. Again we found that education and passing the lessons from the past event is highly
valued to mitigate the tsunami fatalities.
